In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

Demonstrate how to tell the age of an egg without having to crack it open.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot navigate around several obstacles.

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

In this fun science experiment, kids will determine the best method for ripening avocados and discover the cool chemical reaction that makes this possible.

Gymnosperms are coniferous trees that reproduces using pine cones to spread seeds. Check out this simple pine cone experiment to learn about the process!

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

This experiment has students record rat behavior to learn about the benefits of rats and research rat myths throughout history.

Develop your child's mathematical and engineering skills with this fun building brick challenge. In this activity, your learner will be challenged to create a boat out of building bricks.

This science experiment has students test whether a snail moves faster on concrete or dirt.

The objective of this science project is to determine the length of time for different seeds to germinate.

This fun and easy middle school science fair project idea explores the topic of pollution and demonstrates if polluted soil affect the growth of green plants.

Find out whether putting something on top of a plant will inhibit its growth.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

This super fun science project, perfect for young children, combines crafts, dressing up as animals, outdoor play, and life science learning.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

This activity challenges your student to use spatial reasoning and computational thinking to program multiple robots.

This science fair project idea explores whether cats can be trained in the same way that dogs can.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

This science fair project idea attempts to train a worm to complete a simple maze in order to find out if worms can learn and remember.

What animals are most popular? This project affords practice in data-collection, record-keeping and data-analysis through the investigation of this question.

This science fair project idea explores how enzyme inhibitors, active sites, non-competitive enzyme inhibitors, and substrates work.

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

Cinnamon is tasty, but does it have super powers as well? Find out if cinnamon can repel mosquitoes in this outdoorsy experiment.

In this activity, students will be challenged to describe and count the ways a toy moves from one position on a grid to another.

Teach kids about a fun way they can remember this more efficiently- the power of mnemonics. Kids will be amazed.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Magnets vary in strength. Have your young scientist figure out which kind of magnet is the strongest when you have him conduct this attractive experiment.
