Separating Mixtures: Can You Design a Device to Do It?

Science Fair Project Idea

Scientific Method

Have you ever looked in the kitchen cupboard and found a container of tiny white grains, but you were not sure if they were sugar or salt? They look very similar. How could you tell them apart? Well, you know that sugar and salt taste very different. Taste is actually called a property, and properties are used to describe and identify different materials. Properties can also be used to physically separate things. In this science project, you will use different properties to create a way to… Read more

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more

There are many different ways to make slime. In this lesson plan, your students will use the engineering design process to design their own slime product. They will need to decide on the desired properties for their slime and then experiment to find the best recipe. Read more

NGSS Performance Expectations:

3-5-ETS1-1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
5-PS1-4. Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
Optional: 5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved. (see Variations)

Slinking Slinkies

Science Fair Project Idea

Scientific Method

Want to do a project with a toy your parents, or even grandparents, might have played with? Slinkies are fun toys that also make great physics and engineering projects. In this science project you will investigate how changing the angle of an inclined plane affects how the Slinky walks down it. What angle will enable the Slinky to go for the best walk? Read more

Have you ever seen a real virus? Probably not—they are so tiny that it is impossible to see them with your naked eyes. But how big or small are viruses really? The coronavirus Sars-Cov-2, which causes COVID-19, is about 120 nanometers in size. One nanometer is equal to one billionth of a meter! How many of these tiny coronaviruses do you think can you line up inside a pencil dot? In this activity, you will find out by creating a scale model that allows you to compare the size of many… Read more

Solving a 'Windy' Problem

Science Fair Project Idea

Scientific Method

The wind is a powerful force, enough to erode whole hillsides over time. Building structures in windy environments challenge civil engineers with special safety concerns. A wall in a windy area can either shield you from the cold or fall down on you. Learn a few tricks on how to design walls in windy places. Read more

Something's Fishy About That Fertilizer

Science Fair Project Idea

Scientific Method

Did you know that when you use fertilizer in your garden, it can eventually reach a lake, stream, or pond? There are many different chemicals present in fertilizers. How will they affect the aquatic organisms in the ecosystem? In this science project you will get to find out! Read more

Sorting Out Sedimentation

Science Fair Project Idea

Scientific Method

Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more

Speed Quest

Science Fair Project Idea

Scientific Method

Do you like to watch the Olympics and see new world records get set? Have you ever wondered how fast you'd need to go to achieve that world record? Well, in this sports science fair project, you'll find out how to compute speeds needed to achieve world records. Not only that, but you'll learn what speed is, and how to measure it in almost anything that moves! So head for the track, you're on a search for speed! Read more

Spinning Your Wheels: Pinwheel Sensitivity

Science Fair Project Idea

Scientific Method

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more
