Learning About Plant GrowthThis is the 6th part in my plant science series. I hope you have enjoyed learning about plants. What does a plant need? In this experiment you will learn about the needs of a plant. A simple chart can be printed from your computer or drawn by hand to record the results. This chart should include column headings as follows: Plant, procedure, missing requirement, hypothesis and results. This chart should have five rows. Under the plant column simply label each of the four rows with numbers 1-4. Under the procedure column describe what was done to each plant. Beneath the missing requirement column describe what which of the plants needs were lacking. Under the hypothesis column have the kids make an educated guess as to what they think the results will be. Finally, in the results column, record the results of the experiment for each plant (1-4).
You will need: Directions: Purchase or grow your four plants. Number each craft stick (#1-#4). Place one stick into each pot. Place a bag over plant #1. This will deprive the plant of light. Smear the petroleum jelly on the leaves of plant #2. This will not allow air to reach the plant. Place plants # 1, 3 and 4 in a sunny location. Place plant #2 in a closet or in a dark area. Regularly water plants # 1,2 and 3. Plants need water when the soil feels dry when you touch it. Do not water plant #4. This will deprive plant #4 of water.
After about 10-14 days examine the plants and record the results. If there is room at the bottom of your chart have the kids describe which plant looks the healthiest. Have the children decide if the any of the plants can be saved. Replant the healthy plant in a permanent location. If you use beans or tomato seedlings, put the nice one in the veggie garden!
