Did you know that there are more planets than stars in our galaxy? All of these planets circle around a star, but only eight of them—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune—circle around the Sun—the star in our solar system. This activity explores the relative size of these eight planets. Is one bigger than the others, or are they all about the same size?

What's an Abstract?
An abstract is an abbreviated version of your science fair project final report. For most science fairs it is limited to a maximum of 250 words (check the rules for your competition). The science fair project abstract appears at the beginning of the report as well as on your display board.
Almost all scientists and engineers agree that an abstract should have the following five pieces:
Introduction. This is where you describe the purpose for doing your science fair…

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.

Use these free STEM lessons and activities to teach about electromagnetism.
Independently, electricity and magnetism are both powerful concepts in physics. Electromagnetism is the study of how electricity and magnetism can work together, and electromagnetism is one approach to generating electricity.
Teaching students about electromagnetism helps them synthesize what they know about magnets and electricity to see how they can work together. The…

What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic linear accelerator, called a Gauss rifle, of course! Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.…

In this lesson, students will model how traits are passed on from parents to their offspring by creating baby aliens based on their parents' traits. As students compare the physical features of their alien families, they will be able to make the connection between an organism's genotype and phenotype. Students will also learn the difference between dominant and recessive traits.

Use these free STEM projects, lessons, and activities to help students get hands-on exploring and learning about solar system science.
The Earth, the Moon, the Sun, and space are concepts students identify early on. The names of the planets quickly follow, along with stars and the reality that the Sun, too, is a star and is the closest star to Earth. Students learn that the Earth is one of eight planets in our solar system, a group of planets that…
