Product Details

Illuminate students’ understanding of photosynthesis, the process of “putting together with light.” This activity necessitates cooperation among lab groups as experiments are conducted to answer two important questions: Do plants prefer certain colors (wavelengths) of light for photosynthesis? How do environmental conditions affect the rate of photosynthesis? Student groups carry out experiments using Hornwort, an aquatic plant, to investigate changes in the rate of photosynthesis. These experiments involve changing the wavelengths of light, the temperature, light intensity and the concentration of a sodium bicarbonate solution. To discover the answers to the experimental questions, all class data will be pooled, graphed, and analyzed. Kit contains all the chemicals, test tubes and a set of six colored filters needed for 30 students, working in groups of three, to conduct the experiments.

The Hornwort aquatic plant is available separately.

Performance Expectations

HS-LS4-1: Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.
HS-LS4-2: Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
