This science fair project idea explores whether dry ice will cool a beverage faster than wet ice.

Most people assume that cold water freezes more quickly, but could that be false? Does hot water freeze faster than cold water? Let's find out!

In this simple and social activity, children use size comparison skills to find objects in nature that are bigger, smaller, longer, and shorter.

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

Test whether cutting up meats will make it cook faster than just cooking it whole.

Determine if âdouble dippingâ chips really spreads more germs than dipping only once per chip.

Determine whether fresh vegetables have more calories or less calories than canned vegetables.

The objective of this science fair project idea is to determine whether frozen vegetables have more nutrients than canned vegetables.

Determine whether magic salt is more effective at melting snow than regular salt. Pour one ounce of salt over the ice cubes, compare the melt downs.

If it's Easter, it must be time for egg hunts. But we have to admit, most kids would rather take a bite out of a yummy cupcake than a hard-boiled egg.

Forget the measuring stick! This fun math activity uses a body part, your child's hand, as a ruler.

Help your preschooler grasp the concept of ordering and sequence while teaching him valuable vocabulary with simple activities around the house.

Get your child excited about measuring with this fun and easy household measurements activity.

This measurement activity uses feet to compare objects, but not the ones found on rulers and measuring sticks...the feet on your child's own body!

Give your second grader a chance to get his feet wet with measurement before he moves onto the more complicated stuff by trying this activity with him at home.

Measure temperature change over time using a variety of insulation materials. Be creative with insulation materials: scarves, yarn, socks, feathers, oil, etc

This fun activity encourages your child to develop their skills in not only taking measurements, but also in working with the measurements themselves.

This project concerns activity happening millions of miles away, on the sun.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

This science fair project idea determines whether land or water warms more quickly and investigates how solar radiation increases the temperature of surfaces.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

This experiment researches if you gave different amounts of food to mosquito larvae would they grow faster or slower

Introduce the idea of measuring weight to your preschooler or kindergartener by making a fun and easy-to-use bungee scale to weigh household objects.

Encourage your child to compare and contrast a wide variety of autumn-themed items by weighing various objects and recording their findings.

Help your kids fall in love with nature by making a simple clay bird bath. Set it up in your yard and watch the animals venture in for a sip of water.

In this cool experiment, learn about the forces of resistance in a liquid and race marbles in a cylinder to find out which fluids have a high viscosity.

What keeps a an item cooler, polymer crystals or ice? Find out in this cool science experiment!

This project examines the concentration of dissolved oxygen in water, with and without oil.

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.
