Magnetic Levitation: Experiments with 'Anti-magnets'

Science Fair Project Idea

Scientific Method

What happens if you hold a magnet next to water? You might think that water is not affected by magnetism, but in fact, the water is slightly repelled. Believe it or not, if the magnet is strong enough, you can use this effect to levitate objects that contain water, including insects and even small frogs! In this science project, you will learn about diamagnetism. Materials that are repelled by both poles of a magnet are called diamagnetic. The magnets you will use are not strong enough to float… Read more

Biodegradable Plastics

Science Fair Project Idea

Scientific Method

Plastics are made of polymers, chemical structures containing many repeated subunits. How does the polymer type of a plastic affect the biodegradability of the plastic? Do research on how plastic is made and what types of polymers are used for making different plastics. Can you learn to make your own plastic? What materials can you use for making plastic that is biodegradable? Test biodegradability by burying plastic samples for different lengths of time. (Kadar, 2004) Reducing solid waste and… Read more

Build Your Own Microfluidic Device

Science Fair Project Idea

Engineering Design Process

Microfluidic devices are small tools used in different fields like engineering and biomedicine. Scientists and engineers use these devices to work with very tiny amounts of fluids for various experiments. These experiments can include things like biomedical research, creating new medicines, and even applications in the car industry. In this project, you will create and test your own microfluidic device design and compare it to other designs. 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

Candy Snap

Science Fair Project Idea

Scientific Method

Have you ever broken a candy bar in half to share with someone? Some might snap in half quite cleanly, but others might be gooey and flexible. If you stick a candy bar in the freezer, will this change how the materials break? Try this sweet project to find out! Read more

Experiment with Making Gels

Science Fair Project Idea

Scientific Method

Chances are, you have several materials around your house made of gelatinized materials. Gels are used in all kinds of products and materials: pudding, diapers, insoles, packaging, ice cream, toothpaste, and many more. In this project, find out how gels are made and how they can be adjusted from firm to soft by changing the ingredients. Read more

Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials

Science Fair Project Idea

Scientific Method

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more
