Device
Light bulb, buzzer, motor
A person is looking into a pool and sees an image of themselves. Why is that?
Light is reflected by the pond.
If its an open ciruit?
If it is a closed circuit?
if its open its broken
If its closed it flows
What are the forms of energy?
MELTS
Mechanical, electrical, light, thermal, sound
What would be the purpose of having a bush in the desert?
To provide energy for any animal that consumes a producer.
Absorbtion
When light is absorbed by another object and stops it from passing through
What type of materials reflect light energy?
What type of materials refract light energy?
Reflect- Shiny materials
Refract- transparent materials
Draw a picture of a Parallel circuit.
What type of energy does electrical energy turn into to use a TV. Give examples for each.
Electrical energy turns into light and sound energy.
light- the screen produces
sound- the speaker makes noise
A marble is at the top of each ramp, which ramp will the marble travel the furthest?

A
Reflection
The bouncing back of light rrays from a surface.
How does light travel
in a straight line
Draw a picture of a Series circuit.

What is an example of electrical energy transforming into sound energy
An electric guitar
pencil sharpener
a radio
etc.
Students made observations of several different substances and classified them into the groups shown. How could you classify which items go in each group.
Soda, brick, lamp, helium, air, milk
Solid-
Liquid-
Gas-
Solid- brick, lamp
Liquid- Water, Milk
Gas- Helium, Air
Refraction
The bending of light rays as they move from one material into another material.
What happens to the light when you shine it at a prism
A prism separates light by refracting the colors at different angles.
Why does the 2nd light bulb not glow?
The light bulb is not part of the closed circuit.
Electrical energy can only transfer into one other form of energy at a time.
FALSE
Example: A blow dryer transfers electrical energy into thermal energy and mechanical/motion energy
The amount of mass in a known volume of an object or substance
Density
Conductor
Anything that allows the flow of electrical energy
ex. Wires, foil, penny
If you shine a light from position E where would it reflect off of and Why? 
Position A because light travels in a straight line until it is int his case reflected. The angle of incident will be the same as the angle of reflection.
What will happen if the switch is open on the following parallel circuit?
The first two light bulbs would still light up, the last light bulb will not light up.
Give an example of electrical energy transforming into thermal energy
A toaster
an oven
etc.
What is the difference between a mixture and a solution.
Solution- 2 or more substances mixted together, 1 must be a liquid, not easily seperated, properties change
Mixture- 2 or more substances mixed together, easily seperated, properties do not change
