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

Here is a hands-on activity to help third graders understand the four points of a compass...and how we use them to get around.

Create a three-dimensional X-ray of your child's hand in this simple modeling activity. All you need to get started are black paper and drinking straws

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!

Store seeds under three different environmental conditions. Plant seeds in carefully marked groups, watch them grow. Compare results.

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

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

How do crystals form? In this science fair project, students will use three different saturated solutions to see how different minerals form crystals over time.

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

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.

Help your fifth grader trace your family's roots and interview all the living mothers to create a makeshift, 3-D family tree!

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?

In this open-ended activity, students will be given a small quantity of three types of materials and asked to design a prototype for “something that will improve the school.”

Learn how to relight a candle by lighting the vaporized wax in the smoke, and test how various kind of wax and candle brands relight differently.

This experiment investigates whether smell can be used to enhance test subjects' memories.

Check out this cool science fair idea on why hard fruits become soft and learn how to compare the sugar content between ripe and unripe fruits.

Wool can absorb 1/3 of its weight in water, while still keeping the body warm. She can test this theory by performing a scientific sock comparison!

Bake some cookies with an oven that collects sunlight and traps the shorter wavelengths (heat!).

In this activity, young learners will make a balance using a plastic hanger and weigh a variety of small objects using candy corn.

Conduct a simple science experiment to see if flowers from your garden pass the acid-base indicator test with this exciting chemistry activity.

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

Learn how matter transmits sound with a simple, hands-on experiment using sand, water and air.

Explore how you can achieve magnetic levitation with the Meissner Effect! This cool science project explains formation and applications of a superconductor.

In this project students experiment with making music using only glasses of water.

Students identify variables that affect the duration of high school romances and analyze data to predict the success or failure of ongoing relationships.

This fun science fair project idea explains what a circadian rhythm is and explores the types of biological activities that follow a 24 hour cycle in mammals.

This science fair project idea produces sounds by creating vibrations using different objects.

Explore the properties of light and color using photographic filters. Take pictures of color spectrum, compare results of different filters.

The objective of this science fair project idea is to examine light refraction as it passes through liquid crystals.

This experiment demonstrates the conservation and transfer of energy using a marble rolling over sandpaper.
