May 2019: Sea Lions vs Salmon
Developed by Natalie Wolf - Elementary school teacher
Salmon are a crucial part of the Columbia and Willamette Rivers ecosystems. They are also vital to many tribal communities, including Yakama, Umatilla, Warm Springs, Grand Ronde, Nez Perce and Siletz, and important to recreational and commercial fisherman. In the last few years, sea lions have been traveling from the Pacific to feed on the migrating salmon and other fish. They are traveling long distances to the Bonneville Dam and Willamette Falls to feast on the migrating salmon that are slowed by these barriers. Scientists study the rates of migration and numbers of sea lions and have been trying various methods of discouraging the sea lions from eating the salmon. Sea lions have eaten tens of thousands of fish in these areas and are eating endangered fish potentially to extinction. Recently, Oregon was granted legal permission to lethally remove sea lions in an effort to protect the fish.
This lesson starts with students being challenged to think like scientists and develop a solution to a given problem based on information. The explanation of the phenomenon comes at the end as they learn that this is a real-life scenario that is playing out in their own communities.
Discussion on this scientific phenomenon could also offer entry points into conversations around economics, government, and Oregon’s tribal communities, cultures, and history.
GRADE LEVEL: 5 (modifications could be made to adjust to a 3rd or 4th grade lesson but would require more teacher support with the text and notes and more of a focus on life cycles and ecosystem dynamics)
Time: 1 hour
INTRODUCING and EXPLORING THE ANCHORING PHENOMENON
1. Begin class by reading through the challenge with your students. You can show pictures of the Bonneville Dam and Willamette Falls to help them get a sense of the structure and location. Locate them on a map.
2. Using the attached sheet, have students work in teams to read about the problem and make notes about the sea lions, salmon and scientists. While not included in the Army Corp of Engineers’ article, encourage students to also think about how this issue impacts fishermen (recreational and commercial), as well as local tribal communities (Umatilla, Nez Perce, Warm Springs, Grand Ronde, Siletz and Yakama).
3. Support students in the reading and interpreting of the graphs.
What do you see? Help students draw connections between the increase in sea lions with the increase in salmon consumed compared to the previous 10 years.
(Graphs from Army Corps of Engineers study cited on Northwest Power and Conservation Council https://www.nwcouncil.org/news/going-going-almost-gone)
4. Come back together to compare answers and discuss each of the differing perspectives.
Questions to consider:
5. Using the attached planning page, have teams or pairs of students clearly identify the challenge and come up with 3 possible solutions. Come back together as a class and have teams briefly share out a few ideas, developing a class list of proposed ideas. Then give teams time to choose one idea and analyze potential benefits and impacts of their proposed idea. Students should consider how their solution impacts or benefits each part of the scenario.
6. Briefly have teams present their ideas to the class.

INTRODUCING THE ANCHORING PHENOMENON
1. Begin class by sharing the two photos above without photo captions. (Photo credits: Brodeur, et al., 2018.)
2. Ask: Has anyone ever seen or heard of these? If so, encourage students to explain where and when they have observed them.
3. Depending on answers, explain/confirm that students are looking at photos of what are called pyrosomes (Pyrosoma atlanticum) taken along the Oregon coast in 2017.
4. Follow up this discussion by sharing the NOAA video footage of pyrosomes taken 85 miles off of Newport, Oregon to a depth of 100 meters. While watching, challenge students to record at least two observations about pyrosomes that could help them understand how they move or what they might eat and one question they now have about pyrosomes. https://youtu.be/9ovWa83GIOo
5. Create a class list of observations and questions about pyrosomes.
EXPLORING THE ANCHORING PHENOMENON
The appearance of such high densities of a normally tropical sea life in the much colder Pacific has created many questions for marine scientists.
1. Share the four-minute video link below and challenge students to individually listen and record at least three questions marine scientists are now pursuing as a result of the unusual pyrosome sightings. https://www.youtube.com/watch?time_continue=3&v=YLFbQpkrsBY
2. Split students into groups of three and complete a round robin where each student shares one of the questions they listed. As a whole class, record one research question from each group. Possible examples:
EXPLAINING THE ANCHORING PHENOMENON
1. Share with students possible explanations being examined by marine scientists for the high density pyrosome sightings on the Oregon coast:
2. Using the Oregon STEM partners, research articles, and resources listed below, challenge student teams to research which claim the scientific data most supports.
Each team will share their conclusions using the Claims, Evidence, and Reasoning strategy. Teams should also prepare a rebuttal that explains why the unselected or alternative claims are not the best descriptions for the pyrosome phenomena.
CLAIMS, EVIDENCE, REASONING AND REBUTTAL STRATEGY
Make a Claim: A statement that identifies which anchoring phenomena explanation the team agrees is most consistent with the scientific evidence.
Provide Evidence: Sufficient, appropriate, qualitative and/or quantitative evidence that supports their claim.
Share Reasoning: Explain how or why the data counts as evidence to support their claim, provide a justification for why this evidence is important to their claim, and include one or more scientific principles that are important to their claim and evidence.

OREGON'S STEM LEARNING ECOSYSTEM
by Lisa Blank, Director of the Oregon Coast STEM Hub
Oregon science teachers are fortunate to be teaching in a state that supports a STEM Learning Ecosystem approach.
What is a STEM Learning Ecosystem and How Do you as a Science Teacher Benefit?
One, STEM ecosystems convene strategic partners to improve education and connect all learners to STEM experiences across multiple learning environments, from school buildings to libraries to creek beds to factory floors, igniting students’ passions, interests and aspirations. In short, STEM Learning Ecosystems are your everyday partner in supporting your work with students.
Two, STEM Learning Ecosystems were identified in a 2018 federal report as the top strategy for improving STEM literacy. This means Oregon is well - positioned to secure federal funding for STEM educators – this includes science teachers!
The Oregon Department of Education supports thirteen STEM Learning Ecosystems that are most often referred to as STE(A)M Hubs. The map below can help you identify and connect with your STE(A)M hub. As well, you can find more information about your STE(A)M hub by visiting: http://stemoregon.org/.
One consistent message STE(A)M Hubs hear from educators is that they would like more specific teaching supports. To that end, OSTA will begin providing monthly, place-based anchoring phenomena that are unique to each hub landscape, aligned with NGSS, and includes connections to community partners for your students to further investigate the phenomena.
The Oregon STE(A)M Hub Anchoring Phenomena column launches in March with an anchoring phenomena provided by the Oregon Coast STEM Hub. This means you can expect an anchoring phenomena that helps students better understand Oregon's marine and coastal ecosystems and the questions practicing marine scientists daily ponder.
What Makes a Quality Anchoring Phenomenon?
Central to the changes outlined in the NGSS is the understanding that teachers should “anchor” their instruction in observable, complex, and puzzling events that require students to use their science understandings to explain or predict phenomena.
Known as “anchoring phenomena,” these events focus teaching and learning episodes, integrate math and science learning across several weeks of instruction, and require multiple lines of evidence and reasoning on the part of students.
Let's use a marine science example to illustrate. Dr. Leigh Torres (Marine Mammal Institute, Hatfield Marine Science Center) and colleagues are using drone technology to develop a new whale body size metric - termed “Body Area Index” - that enables marine mammal researchers to compare whale body size within and among whale populations over time.
This research context provides an excellent opportunity to anchor student investigations: How can Body Area Index be used to assess the health of whales? What measurements are essential for creating a Body Area Index? Why? How does the Body Area Index vary from the Body Mass Index for humans? What is the ideal Body Area Index for whales? How is the health of whales related to food availability? Do whale populations struggle with food security or obesity like human populations? How should these findings inform commercial and/or recreational fishing policies?
These questions are too complex for students to explain after a single lesson or online search. Possible explanations are observable to students, require the integration of important math and science concepts and access to data, images, and text to engage in a range of ideas, and depend on considering important stakeholders such as recreational and commercial fisheries. As well, understanding the Body Area Index builds upon the familiar concept of Body Mass Index. These criteria are essential for developing quality anchoring phenomena (Bell, 2016).Curious? We hope so! See you next month when the Oregon Coast STEM Hub provides a fully developed anchoring phenomena for you to use in your science classroom. Questions? Contact Lisa M. Blank at email@example.com.
JANUARY 2019: COMMODITIES NEAR YOU
This map from Oregon Agriculture in the Classroom gives a visual representation of Oregon's agricultural commodities. Teachers: order your free copy here!
What's your local agricultural commodity(s), and why is it grown in your region? Asking these questions opens up so many more questions about soil chemistry, local climate, transportation of goods, ecosystems, engineering design, human impacts, and more.
Oregon Agriculture in the Classroom is a great resource to start digging deeper into agricultural commodities and beyond. You can find lesson plans, information about school gardening, and sign up for weekly current events in agriculture.

december 2018: ENGINEERING AWAY PLASTICS

One environmental issue that students easily connect with is plastic pollution in the oceans. For students in Oregon who live on the coast, they likely find plastic trash every time they visit the beach, but this isn't just an issue for coastal communities. New evidence is emerging about microplastics making their way through the food chain into human waste, and even into our indoor air and water supply. While all of the repercussions of microplastic waste aren't yet well understood, we do know that plastics in general are bad news for ocean life and, when used to package foods, aren't great for kids, either. Couple that with the recent refusal of Oregon's plastic recycling from China, and we have a mountain of plastic problem on our hands.
How are engineers working to solve this problem? One Portland design lab is creating paper packaging meant to replace some of the most common plastic waste. Engineers are working towards using biodegradable and recyclable packaging materials that, rather than contribute towards climate change by using fossil fuels, could help sequester carbon through the sustainable harvest of trees.
How can this engineering problem translate to the classroom? We've included a few resources below...
For the earliest grades (PK-1), we'd suggest focusing on the properties of packaging materials. For example, students could drop water on materials and observe what happens, bury them in the compost for several weeks at a time, try different ways to break them down into smaller pieces (or, in the case of paper, make new paper), or design their own tests and carry them out. They could then sort materials by different criteria: whether they think it's easy to reuse or recycle, whether it can biodegrade, whether it's water resistant, etc.
The Ship the Chip activity, designed for students aged 8-18, challenges students to create the lightest possible shipping container to mail a potato chip back to school, safe and sound. This activity could be modified with the criterion that packaging materials must be recyclable and/or compostable. Includes connections to the NGSS and CCSS.
This NSTA blog post, "Striving for a Zero Waste School," describes several schools' journeys to reducing or eliminating waste, addressing issues ranging from school lunch packaging to disposable lab materials. We appreciated that schools addressed lunch packaging by going to their school lunch supplier, rather than appealing to individual families who may be on tight food budgets and/or live in areas where unpackaged foods are harder to come by.
Engineering for Good is an NGSS-aligned three-week middle school unit from KQED Learning, designed to teach students about the issues of plastic waste and guide them through their own design process to solve a plastic-related problem. The unit includes videos and a notebook for students to use. This was our favorite resource that we found - on its face, it seems to be the most student-centered.
NOAA's Marine Debris teacher guide contains ideas for lessons for students aged K-12 that range from identifying what marine debris is, to tracking the movement of trash through a watershed. These lessons are not NGSS aligned (instead, "STEM objectives" are identified), but they include a lot of very important topics and could be modified to better reflect the NGSS and be more student centered.
November 2018: CLIMATE CHANGE

We'll admit that when the IPCC Climate Report came out, stating that if society doesn't drastically curb carbon emissions in the next 12 years we will face grave consequences, it was discouraging news to say the least. We decided to use this issue of TOST to focus on what makes our work as science educators so powerful: We are afforded the opportunity to prepare students to face the challenges of the not-so-distant future.
How is climate change addressed from K-12 in the NGSS? Students in primary grades do not learn about climate change directly, but rather focus on human impacts on the environment, both positive and negative. This starts as early as kindergarten, when students learn about and communicate ways reduce impacts in their communities. Middle school students make sense of climate data through asking questions. In high school, students use data to make predictions about the rate of climate change as well as how it will impact their communities. They also model carbon cycling to better understand the mechanisms of climate change.
It's noteworthy that the IPCC climate report changed the recommended cap on warming from 2 degrees celsius to 1.5. The NGSS includes a document outlining the Nature of Science, which includes a list of scientific understandings, including Scientific Knowledge is Open to Revision in Light of New Evidence. As students think critically about what they might hear about climate change, it's important for them to understand that scientific knowledge is not static, but rather ever evolving as new evidence comes to light.
A topic like climate change can feel overwhelming to approach, and the fact that it's a political hot-button issue can be intimidating. The NSTA Climate Science Resources page includes NSTA's position statement on teaching climate science, as well as resources for educators, parents and community members. As with any science topic, it's helpful to look to observable phenomena in your community as a place to start. Communities across Oregon are already being affected by climate change related or exacerbated issues like tree die-offs, drought and accompanying wildfires, increasing ocean acidification and more.

OCTOBER 2018: FRUITING FUNGI
Fall is officially here! For many, fall means a return of the rains, school starts back up, the temperatures cool down and the days get shorter. For some of us, fall is an eagerly anticipated time of year when the forest floor transforms from dusty and brown to vibrant green, damp and covered in fungal fruiting bodies, otherwise known as mushrooms.How can this local, seasonal phenomenon be a jumping off point for students? Here, we use the Crosscutting Concepts as a lens to ask different kinds of questions about the phenomenon of mushroom growth (linked articles are to provide more information to get the wheels turning...). Note: some of these questions are investigable by students, and some are still unanswered by science!
Systems and Interactions: What role(s) do fungi play within a forest ecosystem?
Matter and Energy: What role do fungi play in nutrient cycling in the forest?
Structure and Function: How do mushroom structures enable their functions?
Patterns: How can we make predictions about when and where mushrooms might grow?
Scale, Proportion and Quantity: What can we learn about the structure of fungi at the cellular level? At the organism level?
Stability and Change: How does a sudden event like logging affect mushroom growth for a particular species?
Cause and Effect: What might cause mushrooms to be so prolific in some years and absent in others?
This STEM Teaching Tool has more helpful ideas around using the Crosscutting Concepts to generate student questions.

september 2018: THE EERY ORANGE SUN

Across the state of Oregon, wildfire smoke has played a major role in our summer, whether it forced sensitive people indoors, canceled large events like the Ashland Shakespeare Festival, or adversely affected agriculture across the state. For those of us who were (and continue to be) negatively affected by smoke in the air, there hasn't been much positive to say about it, except for one thing: the light sure does look pretty. On days of heavy smoke, the sun appeared orange or red in the middle of the day. This is one of many phenomena involving light that you, or students, may have observed when there are high levels of fine particulates in the air.
How would students explain this phenomenon? As an educator, our first task is to think about the age level of our students, and the appropriate level of complexity with which to engage with a phenomenon. For example, first grade students might observe that the sun appears less bright on smoky days, while middle school students might create a model explaining how different frequencies of light interact with particles in the air. Below, we have included the progression of DCIs addressing light waves (click here to see full NSTA document of DCI progressions).

August 2018: URBAN HEAT ISLANDS
Phew! July was HOT. With the exception of the Oregon Coast, Oregonians have been on the hunt for the coolest places to spend the day. This month's phenomenon, urban heat islands, is inspired by the heat wave many of us experienced in July, and involving students in planning climate resilient communities.
Data shows that temperatures are increasing faster in urban areas than in surrounding rural areas, which has the potential to negatively impact human health. In fact, Portland has the fourth highest heat island effect (meaning the difference between Portland temperatures and surrounding rural areas is greater than most cities). The PDX Resiliency app takes localized climate data one step further and assesses the city of Portland by temperature, access to air conditioning, local air quality and more, highlighting who might be most vulnerable to rising temperatures and where to focus mitigation efforts.
Most of Oregon is not urban - are there localized heat island effects that can be detected in rural areas, too?One way to help students better understand heat islands is to study microclimates on the schoolyard. Annenberg Learner's Journey North website provides lessons that are centered around planting a pollinator garden in the part of the schoolyard that is most similar to the local climate. Students map the schoolyard and take temperature data at different locations over a period of time. With the data students have taken, they can then propose design solutions to cool the schoolyard on hot days. (These activities would align well to the NGSS third grade Weather and Climate standards)
What other Disciplinary Core Ideas would students need to know to understand the phenomenon of urban heat islands? How do heat waves impact your community?JULY 2018: KEYSTONE SPECIES IN OREGON'S KELP FORESTS
This month's phenomenon is pulled from Diving Into Oregon's Kelp Forests, a 6-8th grade curriculum from the Coast Aquarium. Diving Into Oregon's Kelp Forests takes a closer look at kelp ecosystems off the coast of Oregon, including the keystone species that keep the ecosystem healthy and diverse. Interested in this topic? The Coast Aquarium is hosting a professional development day on August 3!
From the curriculum:
Compare these two sites. Which site has a greater abundance of species? Which site has a greater diversity of species? Which site appears to have a healthier ecosystem? Why?
To take a "deeper dive" into the idea of keystone species and how they affect Pacific coast ecosystems, view this video (also linked in the curriculum).
After viewing the video, these questions might come to mind: What ecosystems are in my area? What are the keystone species there? How could students explore the effects of absent keystone species? How could students design plans to reintroduce keystone species?
Already engaged in learning like this with your students? We'd love to hear about it. Tweet at us or email us!
june 2018: LIVING WITH ACTIVE VOLCANOES

Aloha from Hawai'i! Leah, the editor of TOST, has the incredible fortune of writing this month's newsletter from the north shore of O'ahu. The eruption of Kīlauea on the island of Hawai'i has many of us thinking about the hazards of living around active volcanoes. Although Kīlauea's activity is unrelated to the volcanic activity in the Northwest (the Associated Press initially erroneously named Hawai'i as part of the Ring of Fire - see correction in the linked article. Whoops!), it is a good reminder to consider the natural hazards we live with every day.
In considering the phenomenon of living with active volcanoes, this sample NGSS unit asks the question: Why do people live and farm on volcanoes? This resource gives an overview of a possible middle school curriculum for the year, with an example of "bundling" Performance Expectations to provide a conceptual flow. This example of bundling PEs could be modified to address living with other geologic hazards, such as a flood plain.
Not a middle school teacher but interested in learning more about NGSS standards related to natural hazards? NSTA has a page outlining ESS3.B: Natural Hazards. Discover your grade band's disciplinary core idea(s) and how they fit into the overall progression of learning.
The Oregon Department of Geology and Mineral Industries (DOGAMI) has a page dedicated to natural hazards in Oregon, such as earthquakes, floods, landslides and tsunamis. What natural hazards exist in your area? How does your community prepare?
MAY 2018: MONARCH BUTTERFLY MIGRATION
This spring and summer, eastern Oregonians are in for a treat: Monarch butterflies make their incredible migration north after overwintering in California. Below are some ideas of how to experience this phenomenon with your students.
April 2018: OREGON SNOWPACK
Consider the difference between these two Snow Water Equivalent maps from January 30 and March 29 :

How is your area affected? How do scientists decide what snowpack levels are "normal"? Why is it important to study snowpack, anyway? Here are some more recently published articles about this phenomenon that might spark some ideas:
To find the SNOTEL maps used above and more interactive data about weather and climate, explore the National Resources Conservation Service (NRCS) website for Oregon.
The Oregon Basin Report from USDA/NRCS contains region-specific information about water conditions in Oregon. Contained in this report are streamflow forecasts, graphs comparing the current snowpack with historical snowpack, and data tables galore.MARCH 2018: THE FLOATING PAPERCLIP AND GENERATING INVESTIGABLE QUESTIONS
When you drop a paperclip into a cup of water, it sinks. But wait! Is there a way to make it float on the surface of the water? Observe here: https://www.youtube.com/watch?time_continue=2&v=fz4jn3h_9VU
Try recreating this phenomenon yourself! It's surprisingly fun considering how simple it is. Engaging with the paperclip phenomenon is a perfect opportunity to practice the process of asking investigable questions. This resource, adapted from The Exploratorium in San Francisco, can guide you through the process.FEBRUARY 2018: ENGINEERING A TIPI
For this month's phenomenon, we're focusing on an engineering challenge: Using the photos, diagrams, and materials, try your best to construct a tipi model.
The following tipi modeling and measurement high school curriculum materials were designed by C Greene. These resources are shared with her permission. We hope they spark ideas for how to plan culturally relevant science, mathematics and engineering units.
