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

Your students might know that they can burn calories, but do they know what a calorie really is? In this fun lesson plan, your students will measure the energy content of food by literally burning it using a device called a calorimeter that they will design and build themselves. This will get your students thinking about the chemistry of energy transfer as well as good nutrition, and gives a whole new meaning to the phrase "burning calories!" Read more

NGSS Performance Expectations:

MS-PS3-3. Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

Can Machine Learning Solve a Maze?

Science Fair Project Idea

Engineering Design Process

Using artificial intelligence (AI) is easier and more accessible than ever! In this project, you will teach an AI to solve any maze. This project requires little to no coding skills; instead you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

Can Nanotechnology Help Clean Up Ocean Oil Spills? Try It Yourself with Ferrofluid

Science Fair Project Idea

Scientific Method

The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

Can You Change the Rate of a Chemical Reaction by Changing the Particle Size of the Reactants?

Science Fair Project Idea

Scientific Method

The ingredients in Alka-Seltzer® tablets undergo a chemical reaction that produces carbon dioxide gas as soon as the tablets hit water. Do you think you can cause the tablets to produce gas faster by breaking them into smaller pieces before dropping them in water? Find out for yourself with this project. Read more

Can Your Body Temperature Tell the Time of Day? Find Out with Human Circadian Cycles.

Science Fair Project Idea

Scientific Method

Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated… Read more

Chlorophyll Extraction

Science Fair Project Idea

Scientific Method

Chlorophyll is a natural pigment found in green plants. It is the primary pigment that absorbs light energy from the sun for photosynthesis. This energy is then used by the plant to synthesize glucose from carbon dioxide and water. Chlorophyll in the leaves of plants can be extracted and separated using chromatography. A good source of chlorophyll for an extraction is a dark green leafy vegetable like spinach. Rub a fresh spinach leaf on the bottom of a strip of filter paper. You can get a… Read more

Clean Up The Water with a Trash-Skimming Robot

Science Fair Project Idea

Engineering Design Process

Engineers are trying to tackle the world's ocean pollution problem using robots. Some robots, like Mr. Trash Wheel and the ship featured in this Mark Rober video, are stationary and collect trash as it flows out of rivers before it gets into the ocean. Others, like the Jellyfishbot, are mobile and can squeeze into narrower spaces to collect trash: Can you build and test your own trash-skimming robot? If you do not have access to a natural body of water to test it in, you can use a bathtub or a… Read more

Click a Button Without Your Hands: Design a Puff Switch

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how you could push a button without using your hands? How would you type on a computer or play a video game? You could use a puff switch - an electronic switch activated by blowing into a straw. This type of assistive device can help users with limited mobility or physical disabilities do everything from using a computer to steering a wheelchair. In this project, you will design, build, and test a puff switch that is connected to a tiny programmable board that you can use… Read more
