Projects with Video Physics Science Projects (7 results)

Physics is the study of matter — what is it made of? How does it behave? What laws or equations describe it? From subatomic particles, to the Big Bang, modern physicists study matter at a tremendous range of scales. There's a whole lot of interesting physics at the human scale, too. If physics interests you our wide collection of physics projects is sure to have an experiment that excites you.

Science Fair Project Idea
Try your hand at this engineering challenge. Can you build a "launcher" device to launch a ball as far as possible and a "receiver" to catch it? Building a receiver provides an extra twist to a traditional catapult project. Add to the challenge by using a limited set of materials to build your machine and calculate a score based on your throw distance and materials used. Read more

Science Fair Project Idea
Do you think you could build a car powered by nothing but air? A balloon-powered car is pushed forward by air escaping from a balloon, and it is fun and easy to build with materials you already have around your house. Can you imagine how you would want your own balloon-powered car to look? Can you design a car that will travel as far as possible? You can even measure your car's speed using your smartphone and Google's Science Journal app. Get ready to grab some simple supplies to bring your… Read more

Safety Cutting some materials, like plastic bottles, can create sharp edges. Young children should have supervision when using scissors or hobby knives.
Science Fair Project Idea
Can you build a volleyball machine? It will need one part to launch a ping pong ball over a net and another to return the ball. How many back-and-forth volleys can you get before the ball touches the ground? While the 2019 Fluor Engineering Challenge is over, you can still try this fun project out yourself. Follow the rules and compare your score to top scores from around the world! Looking for this year's challenge? Check out our main Fluor Engineering Challenge page for all the latest… Read more

Science Fair Project Idea
This is a really fun project even if you don't like going on roller coasters yourself. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much of an initial drop is required to get the marble to "loop the loop." It's a great way to learn about how stored energy (potential energy) is converted into the energy of motion (kinetic energy). Read more

Science Fair Project Idea
Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension. Figure 1. Water striders (image credit Isaka Yoji). You can build your own water striders using thin wire (Figure 2 and following video). Do some background research about surface tension, and… Read more

Science Fair Project Idea
Astronomers can figure out what distant stars are made of (in other words, their atomic composition) by measuring what type of light is emitted by the star. In this science project, you can do something similar by observing the color of flames when various chemicals are burned. Read more

Safety Adult supervision is required. This science project involves creating small, controlled fires. Make sure you follow all the safety guidelines in the Procedure.
Science Fair Project Idea
If you'd like to investigate the physics of amusement park rides, then this project is for you. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much the marble's potential energy at the beginning of the track is converted to kinetic energy at various points along the track.
