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

Determine which metal has the highest rate of conductivity.

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.

This science fair project looks one of the most important factors affecting seed germination: water. A fun and easy plant biology experiment for 3rd graders.

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

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

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

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

This experiment investigates if small changes in your diet can alter your basal body temperature.

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!

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.

Why do plants wilt? Kids will learn to think critically about what environmental factors affect plants, and what plants need to survive.

This experiment evaluates if the temperature of the environment that you work in affects your ability to perform mental tasks.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

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

Explore joule heating and resistance vs. temperature with this cool electricity science fair project that gets kids melting ice cubes with resistors.

The thermometer outside is dip, dip, dipping! What kind of clothes will keep you warmest this winter? This project determines which materials insulate best.

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

Thermometers are how we measure temperature, and we've all heard the terms "centigrade" and "Fahrenheit" tossed around, but what do they really mean?

The objective of this science project is to examine the factors that affect the dispersion of oil in water, including water agitation.

In this experiment you will become familiar with the properties of dry ice while creating interesting effects like ice bubbles!

Cookie catastrophe! In this project you will determine if different types of cookie sheets can cause cookies to bake differently.

This experiment investigates if stress alters body temperature.

This experiment will evaluate bacterial content on toothbrushes before and after different cleaning methods to determine which method of disinfecting is best.
