In this lab, we measured the length, height, and width of our lockers to find the volume. We then multiplied all the numbers and got a volume of 4,830 cm3.

During this lab, we found the mass of 2,4,6,8, and 10 pennies. Then we found the volume by filling the graduated cylinder with water and then placing the specific amount of pennies in the graduated cylinder full of water. We then subtracted the height of the water that we started with from the height that we were at after we put the pennies in. When the mass of the pennies increased, the volume increased at a steady rate. One thing we kept the same was the type of coin which was a penny. After we did that we recorded it in our lab pages.

In this lab, we took pennies and examined them. We then looked at the mint date, the color, and the luster. The A pennies were dirtier or darker than the B pennies which were shinier and looked to be much newer. The B pennies' dates were more recent than the B pennies'. Also, the mass of the A pennies (darker ones) were 6 grams heavier than the A pennies (lighter ones). The volume of the A pennies were 2 cm3 less than the volume of the B pennies. But the density of the A pennies were about 5.3 g\cm3 more than the B pennies.

In this lab, we learned that when energy is not in motion, it is potential and when energy is in motion it is kinetic. When the car was placed at the top of the ramp, it got to the bottom within 5 seconds. To determine the gravitational potential energy at the top of the ramp you need to find the weight of the car and the height of the ramp.

*Hands do not tell temperature*

Heat: The transfer of energy between objects that are different temperatures.
Temperature: a measure of the average kinetic energy of the particles in an object (thermal energy is the total KE of the particles, but temperature is the average KE of the particles)
Thermal Equilibrium: there's no change in either object's thermal energy

They have one hand is in ice water and are putting their other hand in warmer water.

Warm Hand: "feels cold"
Energy is going to the room temperature

Cold Hand: "feels warm"
Room temperature is going to the energy

The final temperature after mixing the hot and cold water together was 41.8 degrees Celsius. The hot water alone was 80 degrees Celsius and the cold water alone was 6 degrees Celsius. The mixed temperature was lower than the hot water temperature, but higher than the cold water temperature. The average temperature of the hot and cold water was always a little bit higher than the actual mixed temperature. So in order to get a pretty accurate mixed water temperature you can find the average of the hot and cold water.
