In the volume lab i learned that you have to measure or read at the bottom of the meniscus. The SI unit for volume is liter. the 50mL of yellow liquid and 50mL of blue liquid didn't measure at 100 because they dissolved into each other and filled into each other creating less space.

The length lab i learned, V=Length times width times height not to look at the ruler from a angle if you do you could cause parallax error. Always measure to the nearest mm. There is maximum possible error, you add the scale uncertainty for each measurement. Minimum scale is the smallest unit of measure

During the mass lab I learned you must zero out the balance before measuring something. Also to move all three masses to the end before beginning. You always start with the heaviest mass in the middle minimum scale

Cars and Ramps- In this lab we are learning about potential and kinetic energy. We are timing how long it takes for the car to go down the ramp (table). We are going to find the weight of the car and the height of he ramp.

Temperature Materials- -Metal -cardboard -plastic -foam -plastic -tile -wood cardboard- felt warm plastic- felt warm wood- felt warm Foam- felt warmest Metal- felt coldest TEMPERATURES- -Metal-21.6 degrees C -cardboard-20.6 degrees C -plastic-21.6 degrees C -foam-21.6 degrees C -plastic-21.6 degrees C -tile-19.2 degrees C -wood-20.4 degrees C

Hands don't tell temperature they sense heat. Heat-the transfer of energy between objects that are different temperatures.

Temperature- a measure of the average kinetic energy of the particles in a object (thermal energy is the total kinetic energy of the particles but temperature is the average kinetic energy of the particles)

Thermal Equilibrium- when there is no change in either objects thermal energy


 * || Test Subject Which tub of water is the warmest? ||

Tub B is 20.8 degrees C Tub A is 21.6 degrees C
 * Zac || Tub B ||
 * Eddie || Tub B ||
 * Luke || Tub B ||
 * Josh || Tub B ||

warm hand- energy to room temperature (feels cool) cold hand- room temperature to energy (feels warm)

The final temperature after mixing the warm and cold water was 35 degrees Celsius, which is between the cold and warm temperature. The average temperature was always a little bit lower than the average temperature. we could prevent the heat lose by putting a lid on it.
