1. Energy! !

2. We are going to focus on:
Energy Transfers;
Energy Transformations

3. Energy is all around us! There is sound energy;
the energy of light and electric energy [and other electro magnetic radiation];
heat energy
The energy of motion [also called kinetic energy];
(In addition there is chemical energy and nuclear energy, not covered in standards through 5th grade).

4. Nature of Energy You use energy when you: hit a softball.
lift your book bag.
compress a spring.

5. Living organisms need energy for growth and movement.
Nature of Energy
Living organisms need energy for growth and movement.

6. Transfer of energy
Some of the kid’s energy is transferred to the baseball
There is a change in the position of the ball over time
A force is involved when the baseball starts moving

7. Electrical energy can be transferred from one place to another and transformed into light or heat.

8. Physical Science Energy: Transfer & Transformations
4-5 PS3A Energy has many forms, such as heat, light, sound, motion and electricity.
4-5 PS3B Energy can be transferred from one place to another.
4-5 PS3C Heat energy can be generated … and transferred from warmer things to colder things.

9. Energy Transfer, Transformation continued…
4-5 PS3D Sound energy can be generated by making things vibrate [PE: …and can be transferred through the air from a source to an observer.]

10. Energy Transfer, Transformation cont.
4-5 PS3E Electrical energy … can be changed [transformed] into other forms of energy including light, heat, sound and motion.

11. EALR 4: Life Sciences
4-5 LS2B Plants make their own food using energy from the sun.
4-5 LS2C Plants and animals are related in food webs with producers (plants make their own food), consumers (animals eat producers and/or other animals) and decomposers (primarily bacteria and fungi) that break down wastes and dead organisms and return nutrients to the soil.

12. Here we have transformation of one form of energy to another.
Light energy to [chemical] energy to make the plant grow:

13. The chemical energy stored in the plant is transformed by the moose into energy of motion and heat (and reserved chemical energy).

14. Energy Transfer & Transformation
Things move, energy makes them move and change, energy can be transformed to different forms of energy.
