Plant Biology Science Projects (53 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.

Use Floating Leaf Disks to Study Photosynthesis
Science Fair Project Idea
Scientific Method
Have you ever seen a (non-carnivorous) plant eat? Probably not! Plants do not get the energy they need from food, but from the sunlight! In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay. In this plant biology project, you can… Read more
Build a Circuit to Automatically Water Your Plants
Science Fair Project Idea
Engineering Design Process
Have you ever taken care of a plant? It can be tricky to get it right. You have to remember to water it regularly, and you also have to make sure to give it the right amount of water — not too much or too little. What if technology could help? In this engineering project, you will learn how to automate the entire process of watering a plant. Using a soil moisture sensor and a pump, you will build a circuit that will automatically detect when the soil is too dry, add water, and stop when… Read more
Grow Plants in Microgravity with an Arduino Clinostat
Science Fair Project Idea
Scientific Method
Can humans grow food in space? Can we grow plants on the Moon or on a space station? This is an important question to answer as humans look to expand our existence to the Moon, Mars, and beyond. In this science project you will build a clinostat, a device that can simulate microgravity right here on Earth and use it to explore the effects of microgravity on plant growth. Read more
Can Every Part of a Plant Regrow?
Science Fair Project Idea
Scientific Method
Have you ever picked a flower and tried to make it stay alive in a cup of water? How long does that last? Do some flowers last longer than others? Why do you think that is? In this experiment, you will compare different plants to see which ones can regrow or regenerate after damage and learn why some plants are better at it than others.  Read more
Make a Biohybrid Robot
Science Fair Project Idea
Engineering Design Process
When you think of robots, you might think of things made out of plastic or metal...but what about living materials? Living materials have one big advantage: they can heal and repair themselves if they get damaged. Since it might not always be easy to repair a damaged robot (for example, a robot on another planet), some scientists want to figure out how to include living, or biological, materials in them to create "biohybrid" robots. In this project, you will create your own simple biohybrid… Read more
Upcycle Paper Products into Plantable Seed Paper
Science Fair Project Idea
Scientific Method
Do you ever have notebooks and papers left over from the school year? Do you recycle them? What if you could use them to start your garden instead? In this science project, you will upcycle old paper into seed cards and test how paper compares to other materials as a fertilizer!  Read more
Monitor Plant Health with a Color Sensor
Science Fair Project Idea
Engineering Design Process
Do you have a garden or houseplants? What about living on or a near a farm? How often do you check your plants' leaves for discoloration? What if you could build a robot to check for you, and warn you if your plants are getting sick? In this project you will learn to use a color sensor to identify different colors on leaves, which can give you a warning about problems like pests, diseases, or nutrient deficiency. Get ready to automate your gardening! Read more
LivingLoom: Clothing With Live Plants
Science Fair Project Idea
Engineering Design Process
LivingLoom looks at how plants can take an active role in making textiles instead of just being used as raw materials. By spinning microgreen seeds into biodegradable yarns, the textiles can actually sprout and grow over time. The project opens up new ways to think about sustainable, care-based design, and invites us to rethink how we connect with plant life through the things we make and use. Read more
Growing Plants on Mars
Science Fair Project Idea
Scientific Method
To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more
A Toxic Test: Can Plants Be Genetically Resistant to Heavy Metals?
Science Fair Project Idea
Scientific Method
Have you ever wondered why a plant that grows well in one environment may not survive in a different environment? For example, plants that grow well in a wet jungle would probably not do so well in a dry desert, lacking enough water. This is because plants have adapted to their specific environment. Some plants have even adapted to tolerate chemicals that would usually be toxic, such as various heavy metals. In this plant biology science project, you will investigate whether different varieties… Read more
