Light Energy
5.6C
- demonstrate that light travels in a straight line until it strikes an object or travels through one medium to another
- demonstrate that light can be reflected such as the use of mirrors or other shiny surfaces - - deomonstrate that light can be refracted such as the appearance of an object when observed through water
How does light travel?
What might happen to light when it strikes a translucent, opaque, and transparent surface?
What might happen to light when it passes through one medium to another?
What types of surfaces or objects reflect the most light?
When is light refracted?
What objects might be used to refract light?
What are some examples of light being reflected?
What are some examples of light being refracted?
Can you predict what will happen to a beam of light when it strikes a mirror?
Predict what will happen when light strikes water.
How are rainbows created?

Thermal Energy
Vocabulary
thermal energy: heat energy caused by the movement of molecules in an object
conduction: the direct transfer of heat between objects that touch
convection: heat moving from one object to another caused by mixing a liquid or a gas radiation: the movement of thermal (heat) energy by electromagnetic waves, such as light waves from the sun

Driving Question - How can your team design a cooler that will insulate a water bottle better than the competition?
Project Requirements - The outer dimensions must be 12 inches long by 8 inches wide.
- The cooler can be no more than 8 inches high.
- The cooler must have enough space on the inside to place a 16 oz water bottle.
(You may use many different materials to use as insulation.)
Test 1: Place a cold water bottle in the cooler. Record the starting temperature and the temperature after 10 minutes.
Test 2: Place a water bottle with heated water in the cooler. Record the starting temperature and the temperature after 10 minutes.
The winning team will be the team with the least difference in temperature for each test.
Electrical Energy
Team Task #1
1. Build a simple circuit.
2. Build a simple circuit with only 1 wire.
3. Build a simple circuit with no wires.
4. Demonstrate and explain the flow of energy in an open circuit.
5. Demonstrate and explain the flow of energy in a closed circuit.
Team Task #2
1. Build a series circuit.
2. Demonstrate and explain what happens if a bulb burns out in a series circuit.
3. Build a parallel circuit.
4. Demonstrate and explain what happens if a bulb burns out in a parallel circuit.
5. Draw and label the flow of energy through a series circuit and a parallel circuit.
Team Task #3
1. Build a simple circuit and create a malfunction within the circuit.
2. Identify the malfunction in another team's circuit.
3. Explain why the malfunction stops the flow of energy in the circuit.
Sound Energy
Vocabulary:- sound energy: a change in matter produced by vibrating objects
- vibrate: to move back and forth
- pitch: how high or low a sound is
- volume: the loudness or amount of a sound
