Your students will design, build, and race balloon-powered cars in this fun lesson plan that teaches about engineering design and kinetic and potential energy. Read more

NGSS Performance Expectations:

MS-PS3-5. Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from that object.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Bottle Rocket Blast Off!

Science Fair Project Idea

Scientific Method

3... 2... 1... 0— blastoff! In this science project, you will use a bottle rocket launcher to launch your own bottle rocket. You will load it with water and pressurized air, make several launches, and find out what makes your rocket soar the highest. Read more

Build a Jumping Robot

Science Fair Project Idea

Engineering Design Process

Can you build a robot that hops like a frog? In this engineering project, you will learn how to build a simple robot that uses the energy stored in a stretched rubber band to jump. You will use the engineering design process to try to make your robot jump higher and farther. How far can you make it jump? Read more

Cleaning up Dyes from Contaminated Waters using Yeast

Science Fair Project Idea

Scientific Method

Have you ever wondered how your clothes got the colors they have? What dyes were used to color them? And after the clothes were manufactured, what happened to any leftover dyes? It turns out that many waters around the world are contaminated by dyes, and this can impact animal and human health. In this science project, you will investigate how active, living yeast may be able to break down dyes in contaminated water. Read more

What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

Genetically Modified Organisms: Create Glowing Bacteria!

Science Fair Project Idea

Scientific Method

Have you ever heard or read about GMO? GMO stands for genetically modified organisms. Scientists can deliberately modify the DNA of organisms, such as bacteria or plants, to change their properties for a specific purpose. For example, crops can be modified to become more drought- or pest-resistant. Genetic engineering is a very powerful tool in biotechnology that has already found many different applications in agriculture, medicine, and industry. In this project, you will engineer a… Read more

Green Technology: Build an Electronic Soil Moisture Sensor to Conserve Water

Science Fair Project Idea

Engineering Design Process

Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

How Much Weight Can Your Boat Float?

Science Fair Project Idea

Scientific Method

Have you ever wondered how a ship made of steel can float? Or better yet, how can a steel ship carry a heavy load without sinking? In this science project you will make little "boats" out of aluminum foil to investigate how their size and shape affects much weight they can carry and how this relates to the density of water.

Have you ever wished your drawings would come alive and the stick figures or objects on your paper could move around? What sounds impossible actually is not! In this activity, you will make your drawing move around by letting it float on water. What makes this possible is the interesting chemistry of dry erase markers. These markers are usually used to write on white boards or glass surfaces and can easily be erased to make space for more writing or drawing. It turns out that they are also… Read more
