Before starting:
Discuss the basics of photosynthesis. Show the following video: https://youtu.be/cX3Iev-JDgM then discuss with the class.
Set-up:
Students will place plants in plastic cups. Plant one will be placed in a window where it will receive light during the day and no light at night.
The second plant will be placed under a desk lamp that will be left on 24 hours a day for the duration of the experiment.
The third plant will be placed in complete darkness (in a closet, cabinet, etc.)
All plants will be watered equally as needed. They will also need access to air.
Day 1:
Students will predict what effect they think each variable will have on the plants.
Students will draw a picture of each plant on "Monday" on handout 1 after students have observed each plant as a class.
Days 2-14
Over the next two weeks students will observe the plants periodically. They will draw their findings on "Friday" of both weeks to record the changes.
Day 14:
Students will draw a picture of what each plant looks like on the final day using "Handout 1". Students will discuss what they found throughout the experiment. They will write why they think the amount of light has the effect that it does on the plants. Additionally, the teacher will discuss the effect that the amount of light has on photosynthesis to wrap the lesson up.
