What we did today on July 24,2008 was Mr. Sherman showed us the right way to do bar graphs. For it to be a good bar graph it has to have: a x and y axis, x and y labels, title, key, and a scale. If you need to know more go to :http://www.ncsu.edu/labwrite/res/gh/gh-bargraph.html.
The next thing we did was the paper towel lab. That was a lot of fun and we loved it a lot. What we had to do was take three different brands of paper towels without knowing which one is which. Then we observed the paper towels and made a hypothesis of witch one would absore the most water. Then we measured 100 ml. of water and then soaked the paper towel in the water until completely covered with water. After soaked in water for one minute we would hold the paper towel over the beaker with the tongs and let it drip all the water that was not absorbed. Then we would see how much water was absorbed. Then we repeated it for the other two.
