Unit Starter Questions:
9/16-17:
1) How can we tell from looking at a crater how much energy a meteor had? 2) List 5 examples of Potential Energy? 3) How could it be possible for an object to have both Potential AND Kinetic Energy at the same time? 9/28-19: 1) What happens to the energy in a battery when the battery is "all used up"? 2) Which ball has more Gravitational Potential Energy? 3) If both balls have the same mass, which will have more Kinetic Energy? 9/20 & 23:
1)How do we know (from our last lab) that a marble with more mass will have more Kinetic Energy than a marble with less mass? 2) How do we know (from our last lab) that a marble placed higher on the ramp had more Kinetic energy than a marble placed lower on the ramp? 9/26-27: 1) Loudness is controlled by what property of a wave? 2) Pitch is controlled by what property of a wave? 3) Light & Sound wave energy travel at different speeds. How do we KNOW this is true? |

The unit packet includes all the work for the entire unit. The packet is turned in all at once at the end of the unit on the day of the test.

Unit/Subject Videos!
"Hot" and "Cold" are words we use all the time and I bet you THINK you know what they mean. But do you really? What exactly do we feel when something "feels" hot or cold? This video does a great job showing what temperature and conduction are really all about:
The Sun is the source for all the energy in our solar system. And it clearly has A LOT of energy! But wouldn't that energy (that keeps it burning) run out by now? What is causing it to keep burning?
Convection and Density Home Experiment!
A nice demo of how Convection works in a fluid material. The second half of the video even throws in some density modelling to remind you about that important function of how matter works. |
