What I learned from the volume, weight and mass lab
From the volume, weight, and mass labs I learned how to use water displacement to find volume, along with a ruler. I learned that the SI unit for mass is grams. We also learned the metric system, and how to use it.

Cars and Ramps Lab
For This lab we tested a chex matchbox car to find its potential energy.We presented our data on the tables below Potential Energy First Run: 3.308 Second Run: 2.904 Third Run: 2.735 Fourth Run: 2.852 Fifth Run: 2.938

After Testing the potential energy we got our height( .05m) and weight(.0338kg) we multiplied them together to get our potential energy total of .017.

Kinetic Energy First Run: 2.308 Second Run:2.241 Third Run:2.248 Fourth Run:2.515

Temperature Lab
The temperatures were similar. Hands do not measure temperature well,they measure heat. __Temperature__-the degree or intensity of heat present in a substance or object, esp. as expressed according to a comparative scale and shown by a thermometer or perceived by touch. __Thermal equilibrium__- a state in which all parts of a system are at the same temperature __Heat__- the transfer of energy between two objects from a high temperature to a low temperature. __Thermal energy__- Thermal energy is the part of the total potential energy and kinetic energy of an object or sample of matter that results in the system temperature.
 * Material || How it feels || Temperature ||
 * Metal || really cold || 21.2 ||
 * wood || cold || 19.8 ||
 * foam || warm || 20.6 ||
 * tile floor || really cold || 18.4 ||
 * plastic || warm || 20.4 ||

Experiment with water
Tub A: 20.2 Tub B: 20.0
 * Test Subject || Which Tub is the Warmest ||
 * 1.Will || Tub B ||
 * 2 Zach || Tub B ||
 * 3 Alex || Tub B ||
 * 4 Shelby || Tub B ||

Prediction: I think my classmates thought that Tub B was warmer because hands can't measure temperature, they measure heat. First -The energy from the water went into the hand "feels hot". The energy from the hand went into the cold water"Ow, that's cold." Second - then we moved the hands into the room temperature water. When we put the hand that was in the warm water into the room temperature water the energy left the hand and went into water "feels cold". When we put the hand that was in the cold water into the room temperature water, the energy from the water went into the hand "that's warm".

Indirect Observation: Ernest Rutherford Demonstration
Every time we rolled the marble under the surface, the marble either came out on the same side or a 40 and 90 degree angle. From all of our lines being drawn in the paper and the empty space in the middle of the paper resembling a square I thought that the object underneath the board was a square.

Chemical Families
my element is silver and my family's name is transition metals. Other chemical families that I heard of are alkaline metals, nonmetals, halogens, and noble gases( pnictogens, chalcogens).

Movie Notes
So far the two families we've learned about are in the Noble gasses and Halogen Family. They are both nonmetal. Noble gasses don't react while halogens do. The halogens are very reactive nonmetals and the Noble gasses ae nonreactive metals.
