Ms. Mandel

2. CT State Science Standards
Describe energy transformations among heat, light, electricity and motion.
Explain how electricity is used to produce heat and light in incandescent bulbs and heating elements.

3. Learning Targets
I can differentiate between potential and kinetic energy.
I can describe energy transformations for a variety of objects.

4. What is Energy? What makes matter move or change
The ability to do work

5. What is the Difference Between Kinetic and Potential Energy?
Kinetic Energy
the energy an object possesses due to its motion
Stored energy
Gravitational potential energy
the energy possessed by a body because of its elevation (height) relative to a lower elevation

6. Forms of Energy

7. Can You Name the Different Forms of Energy?
Mechanical
Thermal
Electrical
Electromagnetic
Nuclear
Chemical

8. What is Mechanical Energy?
energy in an object due to its motion or position, or both

9. Why is Sound Considered to be Mechanical Energy?
Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal.

10. What is Thermal Energy? Heat energy The motion of particles of matter

11. What is Electrical Energy?
Energy caused by the movement of electrons
Easily transported through power lines and converted into other forms of energy

12. What is Electromagnetic Energy?
A form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space
Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwaves and radio bands

13. Electromagnetic Spectrum

14. The energy stored in an atom’s nucleus
What is Nuclear Energy?
The energy stored in an atom’s nucleus
Fission
Fusion

15. Differentiate Between Fusion and Fission
The process by which multiple nuclei join together to form a heavier nucleus
The splitting of heavy nuclei (such as uranium) – into two smaller nuclei

17. What is Chemical Energy?
Energy stored in the bonds of chemical compounds (atoms and molecules).
It is released in a chemical reaction.

18. Learning Target Checkpoint
How do you differentiate between kinetic and potential energy?
Describe the energy transformations from the lab activity. (see the following slides)
