Plant Biology Project Ideas (45 results)

Plants provide us with so much — oxygen to breath, food to eat, materials to make clothing and paper, and beautiful flowers and leaves to admire! How can plants be so diverse and survive in so many kinds of climates? How do they know how to grow towards the sun? Why do some plants not have seeds? Explore the amazing and beautiful world of plants with an experiment from our collection of plant biology projects.

Science Fair Project Idea
We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project, you will investigate how plant tendrils respond to touch stimuli. Read more

Time Required Very Long (1+ months)
Prerequisites This science fair project requires healthy growing plants with tendrils. It may take 3 to 4 weeks to grow the plants from seeds.
Material Availability Specialty items: A growing plant with tendrils, such as a morning glory or sweet pea.
Cost Low ($20 - $50)
Safety Use caution when using the razor blade or craft knife. Adult supervision is recommended.
Science Fair Project Idea
When you go to the supermarket, how do you pick out ripe fruits and vegetables? You might look at their size or color, or feel them for firmness. That might be easy to do when you pick out a half dozen apples, but imagine if you had to examine thousands of apples growing in a field, or strawberries coming down a conveyor belt getting ready for packaging. Suddenly, it is a lot harder to do yourself! What if a machine could pick and sort the produce for you? In this project, you will address part… Read more

Science Fair Project Idea
DNA is the "instruction manual" for the successful growth of a living thing, from a single cell to a mature adult. When the DNA of an organism is somehow damaged, it can have an impact on the organism's development over time. In this plant science fair project, you will track how irradiation (exposure to radiation) of radish seeds affects germination (sprouting of a seedling from a seed). Read more

Science Fair Project Idea
Farmers are constantly battling various types of weeds that compete with the crops they are trying to grow. One of the tools they use to combat unwanted plants is a chemical called glyphosate. Glyphosate is the active ingredient in Roundup, a widely used weed killer. In this plant biology science fair project, you will explore the factors that affect the activity of glyphosate. Read more

Safety Wear disposable gloves when handling the weed killer and work in a well-ventilated area. Adult supervision is recommended.
Science Fair Project Idea
Do you or your family have a lawn, garden, or potted plants that you water regularly? Irrigation—or the artificial application of water to plants and landscaping—accounts for over two-thirds of the world's freshwater consumption (U.S. Geological Survey, 2016)! While that total includes farms, in the United States landscape irrigation still accounts for almost one-third of residential water use. As much as half of that water is wasted due to inefficient watering methods (WaterSense,… Read more
