If water is less dense than dish soap, is water floating or sinking?
Floating
In the movie Toy Story, there is a toy monkey that plays the cymbals once it's switch is turned on. Where does the toy get it's energy from?
The switch activates the circuit to be complete. Therefore, it's energy comes from the battery inside of the toy.
This type of energy powers our school bell every morning.
Electrical energy
All matter takes up space. What is another thing that all matter shares?
All matter has mass.
Which lens shows transmission?
D
Which of the following statements is true?
A) vegetable oil is more dense than water because it floats on the top of water
B) corn syrup is less dense than honey because it floats on top of the honey
C) honey is less dense than syrup because syrup floats on top of honey
D) syrup is more dense because it floats on top of dish soap
B) corn syrup is less dense than honey because it floats on top of the honey
A student attached the parts as shown here and the bulb did not light. The most likely reason the bulb does not light is because...
A) batteries can't provide electric energy
B) the flow of electricity can't make a bulb light
C) the switch must be open for electricity to flow
D) yarn does not conduct electricity
D) yarn does not conduct electricity

D) none of the above
A) more dense than the boat
A group of students created a circuit by using wires, an aluminum battery, a light bulb, and a switch made from wood. They noticed that their light did not light up once the circuit was closed. Why?
Wood is an insulator and not a conductor. Energy cannot pass through it.
The picture below shows a steamboat moving across the sea. What energy change is happening in order to move the boat?
Thermal to mechanical
What is the difference between an open circuit and a closed circuit?
An open circuit does not produce sound, light, or heat due to wires not being connected or a switch being open.

A) light goes straight through
B) light is absorbed
C) light bounces off at an equal angle
D) light is bent
C) light bounces off at an equal angle

Series - one pathway
Parallel - multiple pathways
A) glass marble
B) aluminum can
C) rubber eraser
D) wool sock
B) aluminum can
Two objects that are the same size are dropped into water. One floats, while the other sinks. Why does this happen?
Even though they are the same size, the object that sinks has a greater amount of density than the object that floats.
