Today and last Friday, we worked on a packet in class. The packet was mostly made up of finding the volume of different objects. Also, the packet asked questions such as how to find the volume of an object. The packet also talked about uncertainties. An uncertainty is + or - the measurement. Mr. Finley also said that we always have to use metric measurements i.e. centimeters and milliliters.
In the packet, we had to perform an experiment. We had to find two different ways to find the volume of the following objects: a dice, a coin, a transformer, and a ping pong ball. The two ways my group chose were to use a ruler to measure the object, or use a beaker. First, we would fill the beaker with about fifty milliliters of water. Then, we would drop the object in the water, and measure. Then we would subtract the new measurement by the old one to see the volume. The volume for the dice was 3 ml. The volume for the coin was 0.5 ml. The volume for the transformer was 24 ml. The volume of the ping pong ball is 20 ml.
The last couple of questions were about finding the volume of different objects such as, a bottle of soda, an ipod touch, an Xbox 360, and a bottle of cough syrup. Also, there was a question on how many minutes are in an hour, and how many hours are in a minute. There are sixty minutes in an hour and 0.06666666667 hours in a minute Mr. Finley wants this packet to be turned in.

Good Post! Just curious because since there is 1/60 of an hour in a minute, i got as the decimal 0.01666666666667. Just wondering if i was wrong in my calculations.

Ya thats right but I think is okay to keep it in fractions form. Also just a reminder you have to show your work or Finley will take off points!! When using uncertainty make sure all the measurements are changed. Ex. If the measurements are 5x6x4 then the largest value would be 5.5x6.5x4.5 and the least is 4.5x 5.5x 3.5.
