10/1/13 My Summary of Labs

Length Lab- To start the lenght lab, we wrote down some notes on how to use a ruler than we measured certian objects with a ruler. We then used the formula for volume to find the volume of a rectangular prism. We also predicted and than measured our lockers using meter sticks and the unit of centimeters.

Volume Lab- In the volume lab we learned how to read the volume in a graduated cylinder by looking to the bottom of the meniscus. we measured out 50 mL of blue liquid and 50mL of yellow liquid and mixed them and ended up with 96mL of green liquid. We listed the inferences and discrepancies of our lab results. We than learned about water displacement and how to figure that out.

Mass Lab- In the mass lab, we found the mass of an empty graduated cylinder, then we found the mass of the graduated cylinder filled with blue liquid. After that we subtracted the to masses to find the mass of the blue liquid. we did the same thing to find the mass of yellow liquid. Then we mixed the liquids and made observations.

Materials- 1=coldest, 6=warmest I predict that the metal will be the coolest and the plastic foam will be the warmest.
 * Metal- 21.1
 * Wood- 19.8
 * Plastic Foam- 20.6
 * Rock- 18.4
 * Cardboard- 20.4
 * Plastic- 19.2

Notes on the Lab
 * The temperatures were similar.
 * Hands do not measure temperature well.
 * Hands measure heat. Heat- The transfer of energy between objects that are different temperatures.
 * Thermal[]

4-19-2014 Summary- Indirect Observations

In the lab we found that at almost any point that the marble was pushed under the board, it seemed to hit a wall right away. Out of thirteen trials, five seemed to hit a curve or corner and come out of a different side at a right angle, the other eight came back out of the same side immediately.

From what I can see through my groups indirect observations, the shape we were testing is a red cross type cross.
