This lab asks students to pick a muscle group and push it to the point of anaerobic respiration. Students should have background knowledge before beginning this. This activity can be done using only a stop watch to time reps (sit-ups, push ups, etc.), but I like to borrow hand weights, yoga balls or pilates bands from the gym for extra fun. Kids really get into this activity!
I have uploaded this in a .docx format, so you can edit and differentiate for your classroom and students' needs. Enjoy!
NGSS HS- LS2-3 Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.
NGSS 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.
