2. Electricity… • Did you know that another source of heat is electricity? • Electricity can be found in nature • Lightening is the strongest form of electricity

3. Lightening • Lightening is caused by friction in the air • A mass of cold air rubs against a mass of warm air. • The rubbing together makes a great flash of light and heat energy. • If lightening touches something on the ground, it can start a fire!

4. Let’s make static electricity! • You will need: • A small flat box • Plastic food wrap • Small bits of paper tissue • Directions: • Put the bits of paper into the box • Cover the box lightly with the plastic wrap • Rub your hand on the plastic • Observe what happens to the bits of paper

6. Molecules • All things are made up of tiny parts called molecules. • Molecules are so small that you can not see them unless you are using a microscope. • Some molecules can not be seen at all!

7. Moving Molecules! • When something is heated by friction, fire, electricity, the sun, or your body, the molecules begin to vibrate. • The faster the molecules vibrate, the more heat energy there is. • Heat energy is the energy of vibrating molecules

8. Experiment • You will need: • Two clear glasses • Hot Water • Cold Water • Food Coloring • Directions: • Put hot water into one glass and cold water into the other • Let the glasses sit untouched for 2 minutes • With the dropper put 1 drop of food coloring into each glass • Without touching or moving the glasses, observe what happens to the food coloring in the water • Watch for 1 minute

9. Questions VIBRATE MOLECULES HEAT ENERGY HOT • The food coloring mixed more quickly with the _______ water. • Molecules _______ faster in hot water. • Energy of vibrating molecules is the same as _______. • The smallest part of things are _______.
