Plants are the only organisms on the planet that convert sunlight into food. They do this through a process called photosynthesis which is explored in this activity.
What is needed in this photosynthesis experiments for kids?
A book about caring for plants in the library or bookstore
Your magnifying glass
Your science journal (science experiments for kids)
What should I do in this photosynthesis experiments for kids?
Look in your book about taking care of plants, or ask an adult to find out how much water each plant. Some may need to be watered more than others.
Take two pieces of a plant. Put one in a glass of water. Put one in a glass without water. Check each day to see how it survives that has no water.
Water the plants every other week for several weeks. During this period, fertilize some plants but not all. Label the ones you fertilized.
Record in your science journal the following with respect to the plants fertilized and unfertilized:
Does started to wilt a photosynthesis plant?
Did some plant yellow leaves fell off?
There a growth of plants toward the light (photosynthesis)?
See what happens when a plant (or part of a plant) does not receive any light:
Cut 3 pieces of paper 2 inches by 2 inches. You can cut them into circles or triangles, but you can experiment with other ways too.
Hold it to the leaves of a plant, preferably one with large leaves. You can use a plant from inside or outside the home. Be careful not to damage the plant.
Leave a hung paper for one day, one for 2 days, and a third for a week.
How long does the plant react?
How long it takes the plant back to normal?
Photosynthesis means “putting together using light.” Plants use sunlight to transform carbon dioxide food that exists in the air and water. Plants need this to stay healthy. When the plant has obtained sufficient materials, produces a simple sugar which used immediately or stored as starch. We do not know exactly how this happens. But we do know that chlorophyll, the green substance in plants, helps to make it happen.
