Lesson 3 – Investigating Mealworms Eating (students as investigators and questioners) |
|
|---|---|
|
Activity 3.1: Predictions about Mealworms Eating |
Students develop hypotheses about how matter moves and changes and how energy changes when mealworms eat, move, and grow and make predictions about how they can use their investigation tools—digital balances and BTB—to detect movements and changes in matter. |
|
Activity 3.2: Observing Mealworms Eating |
Students record data about changes in mass and BTB when mealworms eat, move, and grow and reach consensus about patterns in their data. |
|
Activity 3.3: Evidence-Based Arguments about Mealworms Eating |
Students (a) use data from their investigations to develop evidence-based arguments about how matter moves and changes and how energy changes when mealworms eat, move, and grow, and (b) identify unanswered questions about matter movement and matter change that the data are insufficient to address. |
NGSS Performance Expectations
Middle School
- MS. Matter and its Interactions. MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
High School
- HS. Matter and its Interactions. HS-PS1-4. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
