Your kindergartener will have a blast helping you craft these fun, eco-friendly potted place cards.

This science fair project investigates why the number of visible stars changes from place to place.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

Give some of your local ladybugs a warm place to stay for the winter by making a ladybug home with recycled materials.

Study the effects of wind and temperature on evaporation. Place wet sponges in different environments, check at regular intervals, track time required to dry.

The garden is the perfect place to practice math and science with preschoolers. Get digging (and counting, sorting, observing at the same time!)

Demonstrate that insects observe colors and choose favorites. Place colored pieces of construction paper on a flat, glassy surface, observe bug preference.

First graders are learning to think like scientists. What better place to start, then by raising tadpoles? This hands-on activity explores science in action!

Get a cool middle school chemistry project idea on how to determine whether a physical or a chemical change has taken place.

Place mushroom caps on poster board, label samples. Check beneath mushroom caps for "prints" of spores. Record and interpret prints left behind.

What makes your shadow dance around all day? Let's play detective and find out why that sneaky shadow never stays in one place for long.

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

Help your child create a magical miniature garden in the most unlikely of places: a recycled plastic bottle!

Culverts transport seeds away from their original location to different places. This science project examines the effect of culverts on plant growth in streams.

Which public places harbor the most bacteria and germs? Test different environments to find out where the most bacteria live in this science project.

Science fair project that helps you better understand density by comparing the relative densities of cans of Coke and Diet Coke.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

Check out this fun high school science fair project idea to investigate how the cell membrane regulates what moves into and out of cells.

Create your own cloud with an activity that will explain how important concepts such as evaporation, condensation, and precipitation work.

Determine which seeds are most likely to survive harsh winter conditions (low temperatures).

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

This experiment will explore if magnetism has any effect on the regeneration abilities of flatworms.

Create uphill flow of water by using a siphon. Create vacuum by suctioning one end of tube, and submerge it under water. Watch the direction the water travels.

The objective of this experiment is to find out if cooked beans grow faster, if at all, than uncooked beans.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

How does mold grow? Kids find out by testing different conditions to measure mold growth rate and learn about what factors cause mold to grow more quickly.

This experiment explores how microwave radiation affects fungi, bacteria, and plant life.

This science fair project examines the vein structure (venation) of leaves in order to determine the class of the plant sample.
