My Theory

I think that the results of the experiments changed from group to group because that the first experiment was dry soil and on the second experiment the soil was rather wet. That makes the sample and results slightly different.

I'm on the all A honor roll

Today January 29, 2008, I got on the first semester all A honor roll. This is a certificate that states I got all A's for the first semester. So now I have five all A honor roll certificates. Three first semester & two second semester I also have two all year all A honor roll certificates. Now my plan is to finish the year with a first semester(which I just got), second semester, & all year all A honor roll.

Investigate 3 summary

First, we collected all the materials. Next, we scraped our mud into a slope. Then we sprinkled water onto the slope. After that we watched as the water poured out of the tub & into our sample tube. Then we put a bucket under the tub for all the extra water to run into. After that the water formed a trench in the mud. Then, the hole in the tub got plugged.

Investigate 2 summary

First, we put the gravel, clay, and humus in the tub. Next, we collected sand and put it in the tub. Then, we filled our 2 liter bottle with water and put a sprinkler head on it. After that we made a hillside in the tub and poured the water on it. Then, a puddle formed at the bottom of the hill and then it overflowed. After that the water flowed out the hole & into our 50 ml. sample tube. Then, we put a bucket under the hole and waited for the rest of the water to drain out. After that my group put the rubber stopper in the hole, and the experiment joyfully ended.
