Lesson 4 –Explaining How Animals Move and Function |
|
|---|---|
|
Activity 4.1: Molecular Models for Cows Moving and Functioning: Cellular Respiration |
Students use molecular models to explain how carbon, oxygen, and hydrogen atoms are rearranged into new molecules in a cow’s cells. |
|
Activity 4.2: Explaining How Cows Move and Function: Cellular Respiration |
Students explain how matter moves and changes and how energy changes during cellular respiration in a cow’s cells (connecting macroscopic observations with atomic-molecular models and using the principles of conservation of matter and energy). |
NGSS Performance Expectations
Middle school
- MS. Matter and its Interactions. MS-PS1-1. Develop models to describe the atomic composition of simple molecules and extended structures.
- MS. Matter and its Interactions. MS-PS1-5. Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
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.
- HS. Matter and its Interactions. HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
- HS. From Molecules to Organisms: Structures and Processes. 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.
- From Molecules to Organisms: Structures and Processes. HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
