Students study the effects of varying amounts of water on common houseplants.
Students give different amounts of water to common houseplants and observe and record the effects.
plants, water, houseplant
- two each of several varieties of common houseplants, such as cactus and philodendron
- paper or journals
- pens or pencils
- Discuss the conditions most plants need to grow. Ask students to speculate what might happen if the conditions are changed in some way.
- Divide the class into small groups. Assign each group a pair of the same variety of plant.
- Have students place each pair of plants together so that each receives the same amount of sunlight.
- Tell students to give one plant in the pair lots of water and to give the second plant little water.
- Have students measure and record the growth of each plant over a specific period. (Depending on the types of plants, students may not see results for a week, two weeks, a month, or longer.)
- Have each group write a summary of the results and present the findings to the class.
Evaluate students' presentations.
