Innovating Science™ AP Environmental Science: Net Primary Productivity of Aquatic Plants

Description

In this activity, simulate the photosynthesis and cellular respiration of an aquatic plant under different conditions to demonstrate when plants need energy for growth, respiration, reproduction and movement.

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 energy for each process.
• This kit contains enough materials for 8 groups of students and comes with a Teacher's Manual and Student Study Guide Copymaster.
• The activity covers AP Environmental Science primary learning objective ENG-1.A.
