NOTE: Making an electromagnet uses up the battery quickly, so disconnect the wires when you are done exploring. The quickly moving current turns electric energy into heat energy and the wire can get ...
Students make their own chewing gum and observe a polymerization reaction.  Introduction Students will explore the special properties of their chewing gum polymer, and the effect of heat on ...
Students explore the melting and solidification of wax. Introduction Students observe wax as it is heated and cooled, and make observations about this substance as it changes from a solid to a liquid, ...

... of the rolling can will be stored as potential energy in the tightly twisted rubber band (some will be transferred to friction (heat) and sound). Once the band has reached its limit, the stored energy ...
Students fill an ultra-thin plastic bag with air, allow the air to heat up under the sun's radiation and watch the bag float. Students observe the transfer of solar energy to thermal energy and are introduced ...
... as heat behind glass—a solar oven! The glass allows the sun's rays enter the oven. The rays are converted to heat energy and the glass prevents the heat from leaving. Have you ever noticed how hot cars ...
... better than the white sides. The black sides heat up and the molecules in the air around them move faster than the molecules in the air near the white sides. The difference in pressure on the vanes causes ...
... electric current provided by a battery or an electrical socket. The sun can also generate an electric current with the help of the same element that is in sand, silicon. When sunlight heats specially-prepared ...
... extra caution when heating and pouring wax, and remind students never to pour extra wax down the sink! An extra pair of adult hands is useful for this activity. Objectives Students will be able to: ...

Students defy logic by putting flame to a balloon without popping it, thanks to the ability of water to conduct heat. Introduction Water has a high heat capacity. In other words, it takes a lot of ...
... by temperature and density (i.e. how many air particles in a particular space). The Sun heats the Earth unevenly. When air is heated by the Sun, the air particles move faster and expand. This reduces its ...
In this demonstration, students will use differences in air pressure to force an egg into a bottle. Introduction Air expands when it is heated. If air is heated in a container that prevents expansion, ...
