Today on the second, our class objectives were to check and review the Hdub. Then we had to do our daily ? and we finished class working and reviewing the pages seis and siete. Mr. Manning told us that we had a small test tommorow and that each of us needed to buy a ruler and a protractor for the next unit we would be doing. Mr. Manning then showed us a sweeeet demonstration involving one girl and one boy kind of close in size. The demonstration involved a book on the ground with somekind of paper towel on it. The boy had to stand on top of the book and the girl was just on the ground. When they both pushed their hands on each other to try to push the other away, the boy had a lot more trouble staying on top of the book then the girl just not moving on the ground. The boy had a harder time staying on the book because the paper towel had much less friction then just the regular ground. The whole demo was to prove that friction is the key component to winning tug of war battles. If two equal size people are doing tug of war, whoever has more friction on the ground and more friction on the rope will definately win the battle. After all of these demonstrations and discussions, Mr. Manning handed out page 9 for practice on the test. This page was an optional homework assingment but was very helpful in understanding all of the topics covered on the unit for the test. We did start page 9 in class too.
