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.
When you have your X-rays taken at the dentist's or doctor's office, do you ever wonder how the X-ray machine works? Or better yet, how you could make one yourself to use for experiments? This how-to guide provides detailed instructions for high school students and adult do-it-yourself (DIY) enthusiasts to construct and use a homemade X-ray machine safely.
Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland.
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.
Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors.
In physics class, you have probably rolled your eyes at some point after being assigned a "projectile motion" homework problem where you use equations to predict how a ball will move through the air. This experiment will show you just how fun that problem can be by using a real catapult to launch a ball and videotaping it as it flies along its path. Then, you will analyze the video and compare it to what the equations predicted. If you have ever wondered if those equations in your physics…
The first man-made satellite, the Sputnik 1, was launched in 1957. As of late 2020, more than 2,600 man-made satellites orbit Earth, with a little over 70% of them in low Earth orbit. If you would like to delve into how satellites and their sensors are configured, or into how their orbits are planned—and do not shy away from a little programming—this project is for you! With the help of FreeFlyer®—powerful software that allows you to simulate satellite orbit and…
Safety Notes about Neodymium Magnets:
Handle magnets carefully. Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched.
Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer…
If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions.
Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways.
Once you familiarize…
Whether you have already tried the Science Buddies
Build a Paper Speaker activity or the
How Loud Can Paper Speakers Get?
project, or you just like music and are interested in exploring more about the science of sound, then this project is for you.
You probably know that sound waves can have different frequencies. If not, you can read more about that in the background section
of the How Loud Can Paper Speakers Get?
project. The range of human hearing is typically about 20 hertz…
Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably
thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS)
is equipped with its own HAM radio station. The
ISS HAM radio station allows astronauts,
cosmonauts, and space mission specialists from different nations who are on board the space station to talk
to people back home on Earth. Anyone with an amateur radio license is…
