Lesson 3 – Investigating Bread Molding (students as investigators and questioners) |
|
|---|---|
|
Activity 3.1: Predictions and Planning about Bread Molding |
Students (a) develop hypotheses about how matter moves and changes and how energy changes when bread molds and (b) 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 Bread Molding |
Students record data about changes in mass and BTB when bread molds and reach consensus about patterns in their data. |
|
Activity 3.3: Evidence-Based Arguments for Bread Molding |
Students (a) use data from their investigations to develop evidence-based arguments about how matter moves and changes and how energy changes when bread molds, and (b) identify unanswered questions about matter movement and matter and energy change that the data are insufficient to address. |
NGSS Performance Expectations
High School
- Chemical Reactions. HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
- Matter and Energy in Organisms and Ecosystems. HS-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed resulting in a net transfer of energy.
Middle School
- Chemical Reactions. 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.
