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.

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

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more

Have you ever wondered why leaves change from green to an amazing array of yellow, orange, and red during the fall? Leaves get their brilliant colors from pigments made up of various color-creating molecules. During the warm, sunny months, plants use their leaves to turn sunlight into food energy, a process called photosynthesis. This primarily uses a pigment that reflects green light, which gives the leaves their characteristic color. In autumn, when colder, shorter days arrive, many kinds of… 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
Monitor Your Plants with a Soil Moisture Sensor
Science Fair Project Idea
Scientific Method
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
Is It Ripe Yet? Build a Circuit to Detect Ripe Produce
Science Fair Project Idea
Scientific Method
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
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
How Do Flowers Develop?
Science Fair Project Idea
Scientific Method
Flower development is an important part of plant growth. When a plant has reached maturity, it needs to develop flowers in order to reproduce. The male and female parts of the flower have specialized structures for reproduction that develop as the plant matures. How do flowers develop over time? Which structures develop first? You can answer these questions by dissecting the flowers of a gladiola. Gladiola flowers grow and develop along the stem, with the most mature flowers opening at the… 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
Rad Radishes: Effects of Irradiation on Seed Germination
Science Fair Project Idea
Scientific Method
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
