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

Shape Changing with the CyberSquad

Science Fair Project Idea

Scientific Method

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. Which property (or aspect) will change the most: the length of an edge, the surface area, or the volume?

She Shoots, She Scores! How Does Hockey Stick Flex Affect Accuracy and Speed?

Science Fair Project Idea

Scientific Method

While watching an ice hockey game, have you ever wondered what differentiates a good player from a great player? For sure, the great player is athletically superior to the good player. But maybe it is a combination of athleticism and equipment. Maybe a great player knows which hockey stick is best for him or her. Hockey players can choose to play with hockey sticks with different flexibilities or "flex." In this science fair project, investigate how stick flex affects shot accuracy and speed.… Read more

Shoots: How do Mint Plants Branch to Form New Stems?

Science Fair Project Idea

Scientific Method

Do you like to climb trees? The branches of trees are what make them so fun to climb. Each branch starts out as a tiny shoot that grows out from a stem. How is the growth of shoots along a stem regulated? Read more

Should My Robot be More or Less Squishy?

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, we provided a template with four materials: two active materials that expand and contract in the physics sandbox mode, and two passive materials — one hard and one soft. The project mentioned material properties, but it did not go into much detail — you just used the default settings from the template. Changing the material properties can drastically change how your robots behave. Engineers must take material properties into account when designing… Read more

Should We Walk Like Penguins? How Age Affects Your Stride

Science Fair Project Idea

Scientific Method

Watch out for that ice! When winter weather makes sidewalks icy, many people slip and fall. One tip doctors give is to walk like a penguin. That means pointing your feet slightly outward, keeping your center of gravity over your feet, and taking short, careful steps. Research has shown that these changes in stride and posture help people stay stable and avoid falls. These tips are especially helpful for older adults, who are more at risk of falling due to a decline in their balance as they… 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

Size vs. Depth: The Relationship Between the Size of a Seed and Its Ideal Planting Depth

Science Fair Project Idea

Scientific Method

Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one important variable among many that determine the ideal conditions for seed germination.

Skunk Attack! Test Different Remedies to Remove Skunk Odor

Science Fair Project Idea

Scientific Method

Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more

1 review

Students are introduced to the engineering challenges involved with interplanetary space travel. In particular, they learn about the gravity assist or "slingshot" maneuver often used by engineers to send spacecraft to the outer planets. Using magnets and ball bearings to simulate a planetary flyby, students investigate what factors influence the deflection angle of a gravity assist maneuver. Read more

NGSS Performance Expectations:

3-PS2-2. Make observations and/or measurements of an object's motion to provide evidence that a pattern can be used to predict future motion. (Grade 3)
4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object. (Grade 4)
