Science Fair Projects - Plant Growth

Science fair projects - plant growth can look at a number of different aspects of botany. Since many of these projects are hands on and are based on basic science concepts, they work well for young scientists as well as older scientists. Below are several botany experiments that you can complete.

The first science fair projects - plant growth will look at how fast various plants sprout from a seed. To complete this project you will need several different types of seeds, like bean seeds, pea seeds and radish seeds. You will also need moist paper towels and a safe place for your experiment. To complete this project simple soak the seeds over night and then place each in a moist paper towel. Check your seeds daily to see which one sprouts first.

The second science fair projects - plant growth that you can complete will examine the role light plays in seed germination. For this project you will have two test groups. The first group will be exposed to natural light and dark cycles, while group two will not receive any light. Your job is to determine if the amount of light the soil received affected how fast the seed sprouted.

The third type of biology science fair projects that you can complete will look at how temperature affects plant growth. In this experiment you will have several test groups, and you will need plant heating pads. Set each heating pad at a different temperature. Set one at 60 degrees, one at 70 degrees and one at 80 degrees. Then set your pots with planted seeds on each of the pads. Watch your pots for growth and note which pot sprouts first. What does this tell you about seed germination, temperature and seasonal timing?

The fourth free 6th grade science fair projects that you can complete will look at how oxygen impacts the growth of plants. In this experiment you will need two plants and a clear, air tight container. Plant number one is your control experiment. It will be left open to the natural atmosphere in your classroom, and it will be exposed to natural light and dark cycles. Plant number two is your test subject. It will be placed in an air tight container. Since the container is clear it will also be exposed to natural light and dark cycles. Your job is to determine if oxygen is important for the health of a plant. You will want to make careful observations each day abotu both plants. Look for changes in the test plant.

The final experiment that you can conduct will look at how light and dark cycles affect plant growth. In this experiment you will want to have a control plant that is exposed to natural light and dark cycles, a test plant that will be kept in the dark 24 hours a day and a test plant that will be kept in the light 24 hours a day for two weeks. Your job will be to explain the changes and growth patterns that develop. What does this tell you about how light and dark cycles affect plant growth?
