Food Chains and Food Webs
Trace the flow of energy through food chains and food webs, identifying producers, consumers, and decomposers.
Key Questions
- Explain the role of producers in initiating energy flow within an ecosystem.
- Analyze the impact of removing a specific organism from a food web.
- Construct a food web for a given habitat, showing energy transfer.
Common Core State Standards
About This Topic
Global connections are the ways our state is linked to the rest of the world. Students explore how our state trades products with other countries, how what happens in other places affects us, and how technology like the internet connects us all. This topic connects to both geography and economic standards by showing the interdependence of the modern world.
Students learn that our state is part of a global community and that we both give to and receive from other nations. This topic comes alive when students can use collaborative investigations to 'track' the origin of common items in their classroom or discuss the impact of a global event on their own state.
Active Learning Ideas
Inquiry Circle: Where in the World?
Students look at the 'Made in' labels on their clothes, backpacks, and school supplies. They work in groups to map out all the different countries their items came from and discuss why we get things from so many different places.
Gallery Walk: Our State's Exports
Post images of products our state sends to other countries (e.g., wheat, airplanes, software). Students walk through and identify one country that might buy each product and why they might need it.
Think-Pair-Share: The Internet Connection
Students think about one way they use the internet to connect with people or information from another country. They pair up to discuss how this makes the world feel smaller and share with the class.
Watch Out for These Misconceptions
Common MisconceptionOur state is completely independent and doesn't need other countries.
What to Teach Instead
Explain that we rely on other countries for many things we use every day, and they rely on us for the things we produce. A 'Where in the World?' investigation can help students see this interdependence.
Common MisconceptionGlobal trade only happens with big products like cars.
What to Teach Instead
Teach that even small things like the food we eat or the toys we play with are often part of global trade. A gallery walk of state exports can help students see the wide range of things we trade.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
