I created this experiment for my students to observe any differences in using a grow light instead of natural light from the classroom window.
This free product includes an experiment recording sheet and a bar graph.
I partnered my students up. One student put their plant in the window, the other student put their plant under the grow light. As we measure the plants, we record the results for each plant, one bar for the window plant, another bar for the grow light plant. This is why there is a key at the bottom of the bar graph.
I used clipart from My Cute Graphics
to create the experiment sheet.
