This image is an example of
reflection because the light bounces from the water to the air.
thermal energy causing the dolphin to jump.
absorption because the light is bouncing back.
refraction because light is bent when it passes from the air to the water.
How does light travel?
Light travels in a straight line forever and ever.
Light curves around objects as it travels.
Light travels in a straight line until it hits an object.
Light cannot travel at all.

A student builds a circuit made up of a battery, two light bulbs, and a switch. What will the student most likely observe in this circuit?
Light bulb 1 and light bulb 2 will both be on
Light bulb 1 will be off, but light bulb 2 will be on
Light bulb 1 and light bulb 2 will both be off
Light bulb 1 will be on, but light bulb 2 will be off
Will the light bulbs light up in this image?
Yes, both of them will
Yes, but only the one on the right
No, neither of them will
Yes, but only the one on the left
Is this a working circuit?
Yes
No
I'm not sure, I would need to test it myself.
What is missing from this circuit? Why would the light bulbs be off?
The battery, there is no power for the circuit to work.
The switch is open, so the circuit is broken.
The third light bulb, that is needed to complete the circuit.
The wires are not connected properly.
