# Photosynthesis and Cellular Respiration Card Shuffle

## Directions:

- Teacher gives each student one index card.
- Student cuts/tears card into eights and label each as follows:
- O
_{2}
- CO
_{2}
- C
_{6}H_{12}O_{6}
- H
_{2}O
- --->
- energy input (light)
- energy output (ATP)
- Photosynthesis (and on reverse side cellular respiration)

- Students shuffle cards
- Teacher directs students to construct equation for photosynthesis. Note not all cards will be used.

CO_{2} + H_{2}O + energy input ---> C_{6}H_{12}O_{6} + O_{2}
- Student places Photosynthesis cardlet above equation as the title.
- Teacher directs students to construct equation for cellular respiration.

C_{6}H_{12}O_{6} + O_{2} ---> CO_{2} + H_{2}O + energy output (ATP)
- Student places cellular respiration cardlet above equation as the title.
- Repeat as necessary.
