Science Fair Project Idea

Scientific Method

Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Can Beeswax Wraps Replace Plastic Wraps?

Science Fair Project Idea

Scientific Method

Do you ever use plastic wrap to cover a container? Did you know that it is made of plastic, which significantly contributes to the amount of waste in our landfills? There are many alternatives to plastic, and one popular product is beeswax wraps. Are beeswax wraps a suitable replacement for plastic wrap? Find out in this experiment! Read more

Riprap: It's Not Hip Hop But Erosion Stop

Science Fair Project Idea

Scientific Method

Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water. Read more

Fight Flooding and Pollution with...a Garden?!

Science Fair Project Idea

Scientific Method

What looks pretty, stops flooding, and helps fight pollution? A rain garden! Find out how by building and testing your own miniature rain garden in a plastic bottle. Read more

Agrivoltaics: What Crops Grow Best Under Solar Panels?

Science Fair Project Idea

Scientific Method

We need farms for food, and we need solar panels for renewable energy. What if we could combine the two? Find out if certain crops can grow well under the partial shade of solar panels in this agrivoltaics science project. (Note: you do not need access to real solar panels to do this project. Any source of shade will work.) Read more

Which Liquid Works Best for Evaporative Cooling?

Science Fair Project Idea

Scientific Method

When we get hot, we sweat. Sweating helps cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes using what are referred to as swamp coolers. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

Model Water Flow in Rivers

Science Fair Project Idea

Scientific Method

Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape. Read more

Comparing Different Types of Irrigation Systems

Science Fair Project Idea

Scientific Method

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

Building Beaches

Science Fair Project Idea

Scientific Method

A day at the beach is a wonderful way to spend time with your family and friends. You can swim, play games, and build sand castles. But have you ever thought about how all of that sand got there and wondered why the shoreline weaves in and out of the ocean? In this science project, you will investigate how ocean waves build beaches by making a model of the beach and shoreline. All you need is a tiny surfer and a beach volleyball court for your model, and you can imagine that you are in… Read more

Go Fish! Creating an Ocean-Friendly Fishing Video Game

Science Fair Project Idea

Engineering Design Process

Video games are entertainment, but like other such media (say Oscar-winning movies or award-winning books), they can also point out challenges facing people. In this science project, you will design and create a fishing video game that teaches the player about which fish are plentiful enough to catch and which fish are not because their population is declining. Maybe your game can help solve the problem of over-fishing and help sustain healthy fish populations. All while having fun of course! Read more
