2. WARM UP: the Sun!  You may not have used a solar car to get to school today, but the energy needed for the trip came from… the Sun!  How is that possible?

3. Where did the car or bus get its kinetic energy? The car’s kinetic energy comes from burning fuel. Fuel’s chemical energy comes from decomposed micro- organisms that lived in the sea. The tiny animals get their energy by eating plants, which get their energy from the sun. The sun gets its energy from the atoms inside it. The sun is the source of almost all the energy on earth.

4. If you walked to school, where did you get your kinetic energy? CHALLENGE: Make your own diagram tracing back the energy in a toaster as far as you can go! Your energy to move comes from burning food. The chemical energy in eggs comes from the plants the chicken ate. The chickens get their energy from plants, which get their energy from the sun. The sun gets its energy from the atoms inside it. The sun is the source of almost all the energy on earth.

5.  Unlike matter, energy does not have mass or take up space. People and things all around us have energy, but we cannot observe energy directly. Instead, we see only the effects of energy. The wind blows our hair, a toaster browns our bread, or gasoline fuels our car. These are examples of changes that energy causes in matter. From p.51, Gateways to Science Grade 6

6.  Follow these directions with your partner: 1. Hold the neck of the bottle in the ice water for a few seconds. 2. Place the penny over the mouth of the jar. 3. Place some oil around the bottles opening or on the penny in order to provide a completely air tight seal. 4. Now hold bottle in your hands and carefully observe the penny

7. At first, the air inside the bottle is cold, so the air molecules are closer together. When you hold the bottle, heat energy from your hands warms the air in the bottle. The air then moves more, pushing against the bottle, including the penny at the top, causing it to move.

8. STATION 1STATION 2 STATION 3STATION 4 -The ball is less dense than the water so it rises back to the surface. -The dish soap causes the fat in the milk to break down and move away from the other fat particles. -The food coloring lets us see the movement caused by the reaction between the soap and the fat. - Striking the tuning fork causes air molecules to bounce between the two sides of the fork. This makes sound waves and moves the ping pong ball. -The car starts at rest and speeds up as it rolls down the ramp. It makes noise as it reaches the bottom.

26. STATION 1STATION 2 STATION 3STATION 4 Your hand transferred moving or mechanical energy to the ball. Because of gravity, the water moved the ball upwards. Mechanical to Mechanical (Potential to Kinetic) Gravity pulling the car downward transformed mechanical (potential) energy into mechanical (kinetic) energy. Mechanical to Mechanical (Potential to Kinetic) Striking the tuning fork gives it mechanical energy and produces sound energy (moving air particles). The sound energy then transforms into mechanical energy that moves the ball. Mechanical to Sound to Mechanical The dish soap broke bonds in the fat molecules in the milk, causing the milk to move when the chemical energy was released. Chemical to Mechanical

30.  So we can’t make energy, but energy can be made more useful by changing it from one form to another.  Record at least three examples of how energy is changed from one form to another to make it more useful in your own life. ? ? ? ?
