Mass and distance

BOPDs performed an experiment that put two ideas together: force and mass. First they used an informative text to find out how to perform the experiment and this helped them set it up and prepare to perform it. Then they wrote their individual hypothesis based on the problem posed. Working in threes, they explored who mass affects the distance traveled by an object. Using gram weights, cups and tape measure, they each took roles to ensure the validity of the experiment. They tabulated results on the experiment sheet and interpreted the information to write their conclusion. Some students took the experiment further by adding more grams to to the cup and then predicting outcomes. A few groups innovated by taping the tape measure along the projected path to facilitate the accuracy of their measurement in centimeters.

Estimating mass

BOPDs learned all about mass. We explored what it is, how we measure it and how it affects our lives. It was interesting to find out how to measure the mass of an object using a balance. We applied our skills of subtraction to compute for the mass of an object. We also estimated and offered other ways to determine the amount of grams an object has. Using those three measurements as reference we explored the ESL room for objects that may match 2, 30, and 70 grams. We returned to the class and checked on some of our estimates. We also tested the marble measuring 30 grams on our contraptions and found that it meant having to change some part of our creation.
