Where Do Plants Get Their Food?
Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

The Effects of Photosynthesis on Plant Growth
Students are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during the...
Curated OER
Photosynthesis
Students conduct experiments with plants. In this photosynthesis instructional activity, students examine plants under different types of lights. They calculate the amount of dissolved ocygen concentration and compare it to the formula...

Photosynthesis in a Jar
Students simulate Joseph Priestley's experiments using a bell jar. They demonstrate that oxygen is necessary for fire and animals but that given time, plants can create oxygen, allowing fires to burn and animals to breathe.
