Have you ever looked outside on a windy day and seen "helicopter" seeds spinning through the air? Or picked up a dandelion and blown on it, sending the tiny, fluffy seeds flying all over the place? Wind is very important for dispersing seeds to help plants reproduce. In this project you will design some of your own "seeds" and see which ones work best when they are blown across the room by a fan. 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

Can Aloe Juice Save Your Berries from Mold?

Science Fair Project Idea

Scientific Method

Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry—yuck! Companies look for natural, plant-based ways to protect the berries from mold when they are in the store, waiting for you to purchase them. Would washing them in aloe vera juice protect strawberries from mold? Do this project and find out! Read more

Suck It Up: Capillary Action of Water in Plants

Science Fair Project Idea

Scientific Method

Have you ever heard someone say, "that plant is thirsty" or "give that plant a drink of water"? We know that plants, and even bouquets of cut flowers, need water to survive, but have you ever thought about how the water moves within the plant? In this science project, you will use colored water and carnations to figure out where the water goes. Read more

How Do Roots Grow When the Direction of Gravity Changes?

Science Fair Project Idea

Scientific Method

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… 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

One Bad Apple Spoils the Whole Bunch: An Experiment on the Plant Hormone Ethylene

Science Fair Project Idea

Scientific Method

We have all heard the old saying, "One bad apple spoils the whole bunch." Due to the production of the plant hormone ethylene during the ripening process, this saying proves true! This experiment will investigate the role of ethylene in the process of fruit ripening. Read more

Propagate Plants Without Using Seeds!

Science Fair Project Idea

Scientific Method

Did you know that apple trees do not "breed true"? This means that if you plant seeds from an apple, say a Granny Smith, you will get apple trees, but they will make apples that are actually different than Granny Smiths. So how do farmers produce new Granny Smith trees? They use a method called vegetative propagation. For instance, they may cut a branch off of a tree that grows Granny Smith apples and attach the branch onto a different tree trunk. This method of making new trees is called… Read more

What Color Are the Leaves Really Turning?

Science Fair Project Idea

Scientific Method

Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? 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
