Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Teach your first grade scientist the difference between liquids and solids using maple syrup.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

Explore how dielectric heating comes into play when microwaving various liquids in this science project. This test will help you understand how microwaves work!

Kids will learn how to measure the viscosity of liquids by making their own homemade viscometer in this great science fair project idea.

Teach your child some scientific basics as you explore the densities of various liquids in this fun experiment.

In this science fair project, kids observe the expansion of liquids when frozen and determine if some liquids expand more than others in the freezing process.

see whether all liquids evaporate at the same rate. In other words, does water evaporate at the same rate as juice?

In this science fair project, students test how objects float and sink in liquids of different densities.

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Explore properties of liquids and how temperature and salinity effect surface tension of liquids in this fun- filled science fair project idea.

This project examines the affect of temperature on viscosity and surface tension of different liquids.

This science fair project idea examines whether the colors of the spectrum respond differently in the thermal aspect when radiated by the sun.

Kids will make a beautiful rainbow in a jar and learn what enables different types of liquids to remain distinct in separate layers.

Do thick liquids flow faster than thin liquids? Examine water and syrup's viscosity and inertia to learn about the Reynolds Number, laminar and turbulent flow.

Your kid will be captivated as she watches liquids change color before her very eyes during this fun science project that introduces some chemistry basics.

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

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

This is a quick, easy science fair project that conveys the idea of density to upper elementary students.

In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

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