Can Water Plants Be Used to Determine Water Quality?

Science Fair Project Idea

Scientific Method

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Germination

Science Fair Project Idea

Scientific Method

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Do you like your strawberry jelly with or without the seeds? Are you glad to have a seed-free watermelon, or do you enjoy spitting the seeds into the garden? You might not like finding seeds in your fruit, but fruit is a plant's tool for dispersing seeds to create offspring. In this activity you will investigate how many seeds can be dispersed for each type of fruit. Based on the number of seeds they produce, how productive do you think some of your favorite fruits are? … Read more

How Vines Find Their Spines: Thigmotropism in Morning Glory Tendrils

Science Fair Project Idea

Scientific Method

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

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

Radiant Radish Seeds

Science Fair Project Idea

Scientific Method

We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know that the sun gives off harmful radiation and heat. How much radiation and heat can a seed handle? Find out using some radish seeds, an oven, and your microwave! Read more

Students will explore heredity concepts by comparing observable traits of apples and onions, collecting data on the traits of different apple varieties, and learning about apple production. Additional activities include hands-on methods for testing apple ripeness. Read more

NGSS Performance Expectations:

3-LS3-1. Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.

Attack of the Killer Cabbage Clones

Science Fair Project Idea

Scientific Method

Do you like to watch outdated science fiction and cheesy horror movies? Many fictional tales of cloned organisms have been created based upon the scientific method for cloning animals or plants. In the real world, the cloning of plants is a common method used in modern farming. How do you clone a plant? In this science project you will get to find out by making your own cabbage clones!

Bacteria Can Fix It! A Comparison of Nitrogen-Fixing Bacteria and Nitrogen Fertilizers

Science Fair Project Idea

Scientific Method

Do you know what plants need to grow? Sure, they need soil, water, and sunshine. Everyone knows that. But here's a secret: they also need nitrogen. Plants use nitrogen to make DNA in their cells and the proteins that lead to healthy stems and leaves. The problem is, although the Earth's atmosphere is made up of 78% nitrogen, the form of nitrogen found in the atmosphere cannot be used by plants. So how do plants get their nitrogen? Either through nitrogen deposits in the soil, or through… Read more

Cryopreservation: Freezing Plant Tissues

Science Fair Project Idea

Scientific Method

Cryopreservation—storing seeds in ultra-cold liquid nitrogen—is one method for maintaining plant genetic stocks in seed banks. Can seeds withstand a really deep freeze and still germinate? Read more
