• Contains enough materials for 8 groups of students
• Comes with a Teacher's Manual and student study guide copymester
• Aligned with AP curriculum, covering AP Environmental Science primary learning objective ENG-1.A

Living organisms require energy for growth, respiration, reproduction, and movement. Primary producers such as plants absorb energy from the sun and convert it to biomass, via photosynthesis, which is then either used for cellular respiration or passed up the food chain. In this activity, simulate the photosynthesis and cellular respiration of an aquatic plant under different conditions to demonstrate when plants need for each process. This kit contains enough materials for 8 groups of students and comes with a Teacher's Manual and student study guide copymester. The activity covers AP Environmental Science primary learning objective ENG-1.A.
