1. S8P2. Students will be familiar with the forms and transformations of energy.
Explain energy transformation in terms of the Law of Conservation of Energy.
b. Explain the relationship between potential and kinetic energy.
c. Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics.
d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).

2. S8P2A - Explain energy transformations in terms of the law of conservation of energy
Label the following pictures with the type of energy used and created. Type your answers in the boxes
Explain why this flow chart does not follow the law of conservation of energy.

3. b. Explain the relationship between potential and kinetic energy.
Using the “Insert” tab and “shapes” selection, create bars that complete the bar graph to show the percentage of each PE and KE for each point.

4. c. Compare and contrast the different forms of energy (heat, light, electricity, mechanical motion, sound) and their characteristics.
sound
Mechanical motion
light
Moves along conductors
Requires a medium
Moving electrons
heat
electricity
Does not require a medium
Travels as a transverse, mechanical wave
Travels as an EM wave
Directions: Organize the pictures, titles and details into a chart. Each type of energy has three details that match. (You can delete these directions because you will need this space.)
Also called radiant energy
Can be from elastic PE
Can be from gravitational PE
Can be static or current
Moves from areas of hotter to colder
Transfers by conduction, convection or radiation
Will transfer until it meets equilibrium
Has a pitch and loudness
Total KE and PE in a system

5. d. Describe how heat can be transferred through matter by the collisions of atoms (conduction) or through space (radiation). In a liquid or gas, currents will facilitate the transfer of heat (convection).
Type the correct type of heat transfer in the box. (Conduction, Convection or Radiation) 1. 2. 3.

6. S8P4. Students will explore the wave nature of sound and electromagnetic radiation.
Identify the characteristics of electromagnetic and mechanical waves.
Describe how the behavior of light waves is manipulated causing reflection, refraction diffraction, and absorption.
Explain how the human eye sees objects and colors in terms of wavelengths.
Describe how the behavior of waves is affected by medium (such as air, water, solids).
Relate the properties of sound to everyday experiences.
Diagram the parts of the wave and explain how the parts are affected by changes in amplitude and pitch.

7. Move the terms and descriptions into the correct locations on the Venn Diagram.EM

Explain why the person sees this apple as red.

11. Describe how the behavior of waves is affected by medium (such as air, water, solids).
Erase the question and answer the question by restating it.
In what state of matter does sound travel the fastest?
In what substance does sound travel the slowest?
Using the chart. Why do you think that your voice is a higher pitch when you breath in helium?
