Group Behavior for Survival
Students will explore examples of animals living in groups and how this behavior helps them survive and protect themselves.
Key Questions
- Analyze why some animals live in large groups while others live alone.
- Explain how group behavior increases the chances of survival for individual members.
- Differentiate the roles different members play within a social animal group.

About This Topic
Supply and Demand introduces the fundamental economic principle that determines the price and availability of goods. Students learn that 'supply' is how much of something is available and 'demand' is how much people want it. This aligns with C3 standards for Economics by exploring how buyers and sellers interact in a market.
By understanding these forces, students become more informed consumers. They begin to see why the hottest holiday toy is hard to find or why strawberries cost more in the winter. This topic comes alive when students can participate in a market simulation where they experience firsthand how prices fluctuate when the 'supply' of a popular item suddenly drops.
Active Learning Ideas
Simulation Game: The Classroom Market
Give half the students 'money' and the other half 'goods' (like stickers). Run several rounds where the supply of stickers changes, and watch how the 'price' in classroom tokens goes up or down based on student demand.
Think-Pair-Share: The Hot Toy Mystery
Students discuss a time they wanted a toy that was sold out. They work with a partner to explain why the store didn't just 'make more' and what happened to the price if they found it online.
Inquiry Circle: Seasonal Prices
Groups look at 'price tags' for items like snow shovels and swimsuits in different months. They must graph the prices and explain how the 'demand' changes with the seasons, affecting the cost.
Watch Out for These Misconceptions
Common MisconceptionStores just pick prices based on what they want to make.
What to Teach Instead
Use a 'Price Tug-of-War' activity where students represent buyers and sellers. This shows that if a price is too high, no one buys (low demand), forcing the seller to lower it.
Common MisconceptionIf something is expensive, there must be a lot of it.
What to Teach Instead
Discuss 'rarity.' Use examples like diamonds or rare trading cards to show that low supply often leads to high prices, even if the item isn't 'needed' for survival.

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.
