Tree rings can tell the age of the tree but also information about the world. This science experiment uses tree stumps to discover new facts.

Science fair project in which you will learn more about the natural world by preserving and identifying different animal tracks.

Discover whether the â5-second ruleâ is effective at determining whether food is still safe to eat after being dropped on the ground.

This science fair project idea explores whether it is easier to balance on a narrow ledge or on a rope.

This science fair project idea explores plant growth from a bulb, root, and a stem and investigates asexual plant reproduction.

Kids will make predictions about cricket behavior by conducting this fun and easy experiment which simulates different environments for crickets.

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.

Learn about the microclimate of your backyard by tracking rainfall, temperature, and observed weather with hand drawn charts and graphs.

This science fair project idea investigates how the height at which a pendulum is released affects the length of time it continues.

In this science fair project you will make a model of a cell membrane using very simple material.

This science fair project will help students learn about non-vascular plants, such as mosses.

This science fair project idea investigates if fats add to the flavor of food.

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

This experiment explores whether reading text on a computer screen or type on paper leads to better retention of the information read.

In this activity, children will work on their mathematics and engineering skills as they attempt to recreate the Eiffel Tower out of building blocks!

This science fair project explores how osmotic pressure forces water through the root up into the plant.

In this science fair project, students examine under what conditions individual plants release seeds and how far the seeds are released.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.

This science fair project idea investigates how the shape of an object affects drag.

In this science fair project, students will try to discover if test subjects can detect the presence of Monosodium Glutumate (MSG) in food.

How do organic materials become soil? This science experiment measures what materials biodegrade.

In this activity, your learner will be challenged to create their own tic-tac-toe grid out of building blocks.

This tricky building block challenge asks your learner to think creatively. They will work on their divergent thinking skills as they try to fill up an index card perfectly with building bricks.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

The purpose of this study is to determine if people can tell the difference between organic and conventional food from looking at, smelling and tasting it.

Science fair project that determines whether tapping a pomegranate with a spoon helps it release its seeds.

This science fair project examines how seeds hitchhike on animals and clothing.

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

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.
