I put each air-dry clay under two pounds of wieght. After an hour i meausre how thick the clay was in centimeters. Here is my chart:

Air-Dry Clay Height Before Experiment Height After Experiment
Blue 3 cm 1.5 cm
Green 3 cm 1.2 cm
Pink 3 cm .6 cm
Brown 3 cm 2.5 cm

And here are my pics:

The first of a color of clay is the begging of the hour and the second picture of that sertain kind is the end of the hour! In my previous post i put the recipes in case anyonjhe is intersested!

How Conductivity Effects Different Baking Pans 2

After the baking part of the experiment was over, I recorded the observations that I made based from the data table with all the temperatures of each pan. The Pyrex was the best conductor. It gained heat extremely quickly, but surprisingly slowed down once was in there longer. This maybe because glass is known as a insulator and will keep the heat it already has and keep out the heat trying to come in. The metal pan was the second best conductor. The metal pan took awhile to heat up, but kept increasing in temperature. The aluminum pan was the worst conductor, because its temperatures were not consistent throughout the cake.

Trebuchet

Heres a video of the trebuchet firing.

Heres a video of the Catapult firing.

Catapults Versus Trebuchets

Yesterday I began my experiment. I had finished building the catapults on thursday. I placed my catapult and my trebuchet next to each other in an open area. I shot ball one, three times from each weapon, and measured the distances. Then, I fired ball two, which was lighter, three times from each weapon, and measured the distances. I concluded, it was just as I had hypothesized. The catapults throws were much farther than the trebuchets, about two times farther. So my experiment was allot of fun and a great success. I know now that based on a range a catapult would be more fit for battle than a trebuchet.

How Conductivity Effects Different Baking Pans

This post is long over due, since I preformed the first part of the actual experiment on the weekend of March 1st. On that Saturday, I collected all my materials, including 3 Betty Crocker cake mixes, an 9" aluminum pan, a 9" metal pan, and a 9" glass (Pyrex) pan. I then preformed the Pyrex first. I put it in the oven for 10 minutes to start off at 350 Degrees. AFter the 10 minutes finished, I took thermometers and placed them in the center, two on the bottom and one on the top. Until it was 30 minutes, I took the temperature every 5 minutes. These steps were repeated with the other two pans.

Long, Tedious and a Pain in the You-Know-Where (or TJ's Hurricane Experiment)

Sorry for the big delay, but my project was in fact long and tedious, and, as such was hard. However, I did get plenty out of this project. My abstract was the polar opposite of my project short and sweet. Here it is:

Hurricanes cause a lot of damage on costal areas. This damage is among the most costly in the world, sometimes upwards of 1 billion dollars. This damage is from 3 sources: wind, rain and storm surge. Storm surge is the heightening of the tide due to a hurricane. The storm surge was found to be the most dangerous of all portions. Therefore, storm surge should be protected against the most when a hurricane is coming.

I also got several great pictures, and a video.
