Oreo Information
The amount of cream in an Oreo is 3 grams. I found out this information by going to the science lab in my school and got out a measuring scale. It measures in grams. So I could tell by the fact that the scale said the Oreo weighed 3 grams that the Oreo weighed 3 grams. Also I had only put the cream on the scale. So I had to take out the cream with a spoon. The scale has a little hammer that when you move the weights on the hammer goes up and down and when the line on the hammer matches up with the line on the scale you know what weight it is. It is useful because it is something to support my hypothesis. It also helps me understand my experiment because I can guess if there is 3 grams worth of cream in this Oreo. It makes it easier to make a good hypothesis.

Problem
Which surface will the Oreo cream spread farthest on?
Hypothesis
My hypothesis is that based on my research I came up with a guess that the cream will spread 45 centimeters long because the cream weighed 3 grams so I x it by 15 for the cutting board and the card board. For the table I guess that the cream will spread 100 centimeters because it is a smooth surface with nothing that I would suspect to make all of the cream come off the OREO at the same time to make it spread less. So overall I guess that the smooth surface of the table will affect the length that the cream will spread.

Materials
* Pack of Oreos
  • Cutting board
  • Pencil
  • Note book
  • Paper towels
  • Table
  • Piece of cardboard

Procedure
1. Collect a pack of Oreos, a roll of paper towels, a cutting board, a piece of cardboard the size of a cutting board, and a table that you can easily clean.
2. Open 1 of the Oreos so that the cream is showing and if the cookie breaks than keep doing it until you broke one in half that the cookie does not break (what the pack of Oreos is for.)
3. Put the cutting board on a table and hold it still with one hand so that the other hand is free.
4. Use the cracked open Oreo and scrape the cream from one side of the cookie on the cutting board starting from the left side of the cutting board to the right.
5. Repeat step 4 but move down on the cutting board.
6. Make sure that one line does not touch another.
7. Do this until all of the cream is off the OREO.
8. Measure how long the cream is in centimeters with a ruler.
9. After you have measured the length record the length.
10. Than wipe the cream off of the cutting board with a paper towel.
11. Repeat step 3-10 three more times.
12. Average the amount of cream. I recommend a calculator or computer. To average it, just add up the answers you got and divide it by 4
13. Than do the same thing but with the piece of card board
14. Than do it again but on a table.
