Tenth Grade Physics Science Projects (20 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.

Measuring Sugar Content of a Liquid with a Laser Pointer
Science Fair Project Idea
Did you know that you can figure out how much sugar is in a liquid without ever tasting it? In this science fair project, you will learn how to measure the concentration of sugar dissolved in a liquid by using a laser pointer, a hollow prism, and some physics. You will discover how refraction, or the bending of light, is the key to measuring the sugar content of a liquid with a laser pointer. Read more

Is your Physics Textbook Lying? Linear & Nonlinear Springs
Science Fair Project Idea
Spoiler alert: Your physics textbook might contain an inaccurate equation. Are you shocked? Let us explain — many questions in your physics textbooks are simplifications of how things behave in the real world. For example, in physics textbooks, springs are usually modeled with the equation Force = stiffness x displacement: Equation 1: [Please enable JavaScript to view equation] F is the force in newtons (N) Δx is the spring's… Read more

On the Rebound: The Height Limits and Linearity of Bouncy Balls
Science Fair Project Idea
You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In this physics science fair project, you'll investigate this energy storage and transfer, not in a plant or animal, but in bouncy balls. You'll find out if there are limits on how much energy can be stored and if there are losses when the energy is transferred. Read more

Particles in the Mist: See Radioactive Particles Decay with Your Own Cloud Chamber!
Science Fair Project Idea
Are you fascinated by radioactivity and the emission of particles caused by the disintegration of an atom? This science project enables you to observe safely a spectacular display of radioactive decay. Following the instructions in the Procedure, you will be able to isolate a safe radioactive source and build a cloud chamber to watch the radioactive decay. Then you will use your cloud chamber to discover if a plastic lid can shield you from this type of radioactive decay particles. Read more

Prerequisites Basic understanding of, or willingness to study independently, the atomic model and what radiation is.
Material Availability Specialty items are required. See the Materials tab for details.
Cost Average ($50 - $100)
Safety

You will be working with radioactive material in this science project; it is completely safe as long as the simple safety instructions in the Procedure are followed.

This project uses isopropyl alcohol, a flammable product. Do not use it near an open flame or anything hot.

Dry ice is colder than regular ice and can damage your skin. Wear insulating gloves when handling it.

If you choose to take apart a smoke detector, be very careful when cutting through metal or plastic. Cut edges might be sharp. Adult help and supervision is required. Minor injury is possible.

Simple Harmonic Motion in a Spring-Mass System
Science Fair Project Idea
Many things in nature are periodic: the seasons of the year, the phases of the moon, the vibration of a violin string, and the beating of the human heart. In each of these cases, the events occur in repeated cycles, or periods. In this project, you will investigate the periodic motion of a spring, using a mini Slinky®. You can also measure the motion of your spring using Google's Science Journal app. Basic physics will then allow you to determine the Hooke's Law spring constant. Your… Read more
