See the following Web sites for appropriate laboratory activities:
1. In this inquiry lab, students investigate how photosynthesis and cellular respiration affect gas levels in a closed ecosystem.
2. In this investigation, students use chromatography to separate plant pigments.
3. In this lab, students test factors that affect the rate of anaerobic respiration in yeast.
These Web sites may also be helpful:
4. Students can find interactive animations of photosynthesis at this Web site.
5. This Web site has animations of the Calvin Cycle. It keeps a running tally of ATP and NADPH.
