Length lab- Volume=length*width*height, si unit is centimeters. Also we learned how to find the minimum scale and scale uncertainty.

Volume lab- we learned how to find the volume of an object in cm. Then we learned how to convert measurements into different units. We also learned how to find volume using water displacement.

Mass- We learned how to measure mass using a triple beam balance. Also we learned how to find the mass of a liquid by measuring the mass of the cylinder with the liquid. than subtracted the mass of the cylinder by itself from the mass of the cylinder and the liquid. []

The Match box car had a big curve when it went down the table. This changes the time dramatically. We decided to put the car down the table backwards and it worked better. About 2 seconds to the bottom of the table. The height of the ramp is 5 centimeters. We found the weight of the car and the height of the ramp to calculate the potential energy. To find the kinetic energy we used the formula mass times velocity squared divided by 2, we got .015 joules.

The temperatures were similar. Hands do not measure temperature well. Hands measure heat, heat is the transfer of energy between objects. Thermal equilibrium is the point at which two objects reach the same temperature as the one in the room. Temperature is the average kinetic energy of the particles in a substance.

Marble Activity Observations Summary In this experiment we noticed some very interesting results about were the marble came out when we put it in. When the marble was placed in the middle of each side it came right back out. But when the marble was placed on the right or left of the top and bottom it came out on the side opposite of it, like the marble hit an angle.

Numerous inferences can be inferred because if the results we observed. We can conclude that our object has both flat and angled surfaces. We cannot determine what kind of material the object is made of but, we know it has to be solid enough to make a change on the marbles course.

Halogen non metals are very reactive with other elements. Noble gases are non metals that are not as reactive as halogens.
