Science Fair Project Idea

Scientific Method

Have you ever seen those cool wind tunnel pictures of cars with streams of smoke blowing over them? You do not need access to a wind tunnel to do a car aerodynamics science project! In this project you will use cheap, readily available materials—tape and yarn—to visualize airflow over a car. You will examine how you can affect the airflow over the car by making changes, like adding or removing accessories or making body modifications out of cardboard and duct tape. Maybe you can… Read more

Grow Vegan Kombucha Leather

Science Fair Project Idea

Scientific Method

Do you love the look and feel of leather? Many luxury items like handbags, belts, wallets, and coats are made from leather. What if you could make your own vegan leather in a few weeks? Could it be a greener, more sustainable option than cowhide leather? In this science project, you will grow your own vegan leather from kombucha and see how different growing conditions affect the resulting leather. Read more

Which Kind of Wood Burns Slower?

Science Fair Project Idea

Scientific Method

Do you ever go camping with your family and roast hot dogs and marshmallows over a campfire? If you want your campfire to burn long into the evening, what is the best wood to use? Do research on the necessary conditions/materials to sustain a fire and on the properties of different types of wood. Which properties do you think will be most important for determining how fast the wood burns? For example, how do you think density would be related to burning rate? Why? Measure the density and… Read more

Sustainable Construction: Building with Mushroom Roots

Science Fair Project Idea

Scientific Method

Does growing your own house sound futuristic? If so, this project might surprise you! An overlap of biology, material science, and environmental science has resulted in some intriguing self-assembling materials. In this project, you will grow one of these materials: mycelium composite. It is made of agricultural waste and mushroom roots. You will explore two ways to grow your own construction material. Try it out and see which method proves to be the strongest! Read more

Study the Effect of Fertilizers on Algal Growth

Science Fair Project Idea

Scientific Method

You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more

Recycling Greywater: Can Plants Tolerate It?

Science Fair Project Idea

Scientific Method

One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more

The Pasta Puzzle: How Much Water is Required to Cook Pasta?

Science Fair Project Idea

Scientific Method

A plate of spaghetti, meatballs, and marinara sauce is a delicious and comforting meal. It's also an inexpensive meal, because it only costs about $12 to feed a family of four. And it's easy to make when you're on the go and need to eat a quick, but healthy dinner. Just boil a big pot of water, throw in your favorite pasta, cook for 11 minutes, drain, and top with meatballs and warm marinara sauce. Quick and cheap! But sometimes it feels like forever when you are waiting for water to boil,… 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

Have Your Chips Lost Their Chomp? Understanding How Food Becomes Rancid

Science Fair Project Idea

Scientific Method

You are looking under your bed for that video game you want to play, when you come across a real treasure—an open bag of potato chips that you forgot about! A crispy and salty potato chip is a tasty treat. But wait! This potato chip is not crisp and does not taste as great as it should. What happened? The chips have gone rancid! In this cooking and food science fair project, you will look into what factors turned your chips rancid. Read more

What Do We Do With Our E-waste?

Science Fair Project Idea

Scientific Method

If you made a pile of all the electronic devices (cell phones, computers, stereos, televisions, MP3 players, video game systems, remote-control toys, etc.) that your family has gotten rid of since you were a baby, how big would that pile be? Would it be taller than you? Would it fit better in a wheelbarrow or in a pickup truck? And did they just throw it in the trash? In this science project, you'll explore what people in your community do with electronic waste, commonly called e-waste, and… Read more
