Knowing More About Photosynthesis Lab Experiments

It can be hard for the younger students to understand the science of photosynthesis with no hands on activities that will let them see what they are studying. But there are some lab experiments that are teaching the basics of photosynthesis which can be done for students in elementary school. The lab experiments will show the theoretical elements of photosynthesis because they will show what are the effects of sunlight deprivation on the plants instead of showing how the plants will be converting the sunlight into food.

You need to know that sunlight deprivation is.

Once you will know the basics of photosynthesis and how plants are producing sugar from the sunlight, you will be aware on the effects of sunlight deprivation. The students can pot two plants in small paper cups which can be bean sprouts or other affordable plants that are fast growing. Each child will place one plant on a sunny windowsill and the other plant inside a closet without windows. Each plant will have equal soil and will be watered in a span of one week. The plant that is sun-deprived will show how plants are harmed without photosynthesis.

What are the lab experiments with chlorophyll.

The experiment on chlorophyll is important to the study of photosynthesis because it plays an important role in helping the plants get the power from the sun. This lab experiment will use simple materials such as coffee filters, acetone, glass jars, and scissors. Two or three big leaves will be cut up by the students. The students will then mix the leaf in acetone and allow it to sit for one day. The students will take strips from the coffee filter and dip one end of the strip into the acetone. The chlorophyll will be visible as strip of green once the plant chemicals are released by the acetone moving up to the coffee filters.

What are the chemical reactions of photosynthesis?

Once the students will learn the basics of photosynthesis, the educators will give them a simple experiment that will show them first hand the number of photosynthesis chemical reactions. The students can make use of small plants that they can get from aquarium stores and place plant samples in test tubes filled with water which they will cork. After the course of 30 minutes, the walls of the test tube will be seen with tiny air bubbles. The tiny air bubbles are evidence on how the plants are converting water or hydrogen and carbon dioxide into food or carbohydrates. This simple lab experiment will show the students one of the chemical reactions of photosynthesis.
