During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Start this mini unit on matter out by demonstrating how food coloring behaves when placed in cold and in hot water. Then have the class experiment with warm water and soap film. Pupils will learn that an increase in thermal energy also...

Explore thermal energy with this short episode. Jiggling molecules and hand-drawn animation help to explain that just because something has a lot of thermal energy, it doesn't necessarily feel hot to the touch. This is an ideal addition...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Let's heat things up! This simple experiment demonstrates for students the important role the sun plays in providing the earth with energy. Place one cup of water in direct sunlight and one in shade, then take measurements in order to...

Three experiments are shown to demonstrate thermal conductivity. Dr. Carlson is amusing and educational at the same time. Show this video in your chemistry class when teaching about heat conductivity, especially if you do not have the...

A difficult-to-grasp concept, the fact that even cold objects contain heat energy, is the focus of this hot little video clip! Bill Nye tells physical science learners that heat is, by definition, the motion of molecules. He compares the...

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

More than a week's worth of investigation is provided in this source. Physical science stars experiment to describe specific heat, conduction, convection, and radiation. They also discover the relationship between mechanical and thermal...

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

Who needs a barbecue grill to cook hot dogs when you have the amazing power of the sun at your disposal? Engage young scientists in learning about solar energy with this fun activity that turns a used Pringles can into a solar powered...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

What a terrific way to explore temperature! Little scientists can use this resource to make their own large thermometer and measure hot and cold liquids. They can then come up with their own experiment ideas or discuss how it might be...

Mystify your class with this terrific experiment. Take an open photo chip bag with a foil lining and microwave it. The results are amazing! Afterward, have your class discuss why the bag went from a normal size to a much smaller one.

Here is an interesting demonstration which shows how heat can create sound in a metal pipe! The principle of heat rising is the key to making this particular demonstration a success. A piece of metal mesh is lodged inside each of the...

Have your class explore how a hot air balloon works. Through a simple demonstration, learners can see the process up close, and discuss why this occurs. They can then perform related experiments on their own.

This flick opens by revealing the enormity and extreme heat of the sun through a very old-fashioned cartoon. A solar eclipse is explained by Mr. Nye, and a safe way to examine an image of the sun is demonstrated. That's the extent of...

Students discuss what heat is and how it travels. They discover that one way to cool an object in the presence of a heat source is to increase the distance from it or change the angle at which it is faced.

Very young scientists who are learning about solids, liquids, melting, and freezing will use this worksheet to identify things that would melt if put in a warm place. There are eight objects altogether, and learners place a check mark...

Young scholars explore the steps involved in the formation of metamorphic rock as they prepare a cookie receipe. As part of the process, sedimentary rocks are created and changed through heat to a metamorphic cookie.
