In the length lab we learned the volume of our locker and the formula of volume; which is L*H*W=V. It dosen't matter whitch side you laid the prism on it's always the same. We also learned the SI unit for legnth, meters.

In the volume lab we mixed two different liquids together, 50 mL each. When we puored them together they didn't equal 100 mL, instead it equaled lower than 100 mL like 98mL. We also found the SI unit for volume, Liters.

In the mass lab we measured the mass of a graduated cylinder empty, then full of yellow liquid. Then we maesured another cyinder empty, then full of blue liquid. We then subtracted the cyinder's mass from the the liquid's mass. We then mixed the liquids together and measured it's mass. We learned SI unit for mass, grams.

Our results from the penny lab didnâ€™t really match any pattern except that the whole numbers are all divisible by six. The result from two pennies on the triple beam balance was 6.23 grams, while four pennies was 12.45 grams. A difference of 6.22 grams, but this does not carry on to the other results.

Dec 5th Racing Cars

Practice

First run: 3.308 seconds

2nd run: 2.904

3rd run: 2.735

4th run:2.852

5th run:2.938

summary: The car does somewhat curve at some points, and goes around 2.9 or 2.8 seconds down the ramp.

potential energy: to find this energy we need to find the weight of the car and how high the ramp is. PE= W * H

Kinetic energy: we need to find the mass of the car and the velocity of the car. Then multiply them together.

the height of the ramp is 5 cm or .05 meters. 5 cm divided by 100 = .05

The mass of the car is 33.8 divided by 1000 = .0338 kilograms

.0338 times a number equal 33.124 newtons
