Students recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...

Students conduct experiments with plants.  In this photosynthesis lesson, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula for...

Students compare the efficiency of producing food calories in different types of food then calculate how much land is required to supply their food for a year. They then graph the results.
