The 1st students of Mrs. Ponton�s class participated in the O.R.E.O. Stacking Project. We stacked our Oreo� cookies to see how many we could stack before they tumbled. After everyone stacked their cookies, and counted the results, we fiound the average number of cookies stacked and submited our data. Our average was 22 cookies.  Please visit the 2007 O.R.E.O. Project for further details. Procedures First, teams of 3-4 students predicted how many Oreo cookies they coulkd stack, before they tumbled. The predictions were recorded on our class prediction chart. Next, each team had two attempts to stack the cookies, without any adjustments. Once the cookies were placed they could not be readjusted or moved. Finally, each team reported their best tower and added their data to the class list and an average is found when everyone has a turn stacking the cookies. Click HERE to see some of us at work! We are practicing our scientific skills as we observe, questione and describe. Each student is given one Oreo cookie and a hand lens. They record all the information they can discover about their cookie in science lab notebooks. The observations are listed on our data board. Teams also weigh a cookie to find its mass. Mass Investigation We are using a package of Oreo cookies to investigate the scientific theory: The mass of an object is equal to the mass of its parts. To do this we measure the mass of a full bag of Oreos. Then we open the bag and find the mass of the bag by itself, the plastic sleeve (that holds the cookies inside the package) and the cookies. We add up these and compare with the mass of the whole, unopened bag of cookies. Somethimes we find a difference and form ideas for why this might happen. Oreo Writing Each of the 12 classes will be writing poem about Oreo cookies. They will be posted soon! |
