Third and Fourth Graders explored the Scientific Proecss and participated in the O.R.E.O. Project.


They extended their study by desiging and implementing their own Oreo Experiments.

Check out their scientific thinking below.




ON AVERAGE WHICH COOKIE STACKES THE HIGHEST, OREO'S OR SHORTBREAD?


Hypothosis:We think Oreo's will stack higher because they are stable and hard.

Materials
Flat surface
Paper to record on
Short bread cookies
Oreo cookies
Procedure
  1. Have a paper to record on
  2. Start stacking Oreo's on flat surface.One at a time.[ not double stuff]
  3. Even if only a few fall it is a tumble and you need to start over
  4. Record your data
  5. Start stacking short bread cookies
  6. The cookies can not lean on anything
  7. You can not adjust the cookies after tou take your hand off the stack
  8. Record your data
  9. Find your average
  10. make a conclusion

OUR CONCLUSION
We found out that oreo's stack more than Shortbread cookies.
The Oreo's were stacked in the twenties. The Shortbread cookies were stacked in the tens.

Further Questions and Ideas
Would other cookies such as sugar cookies stack better or worse than the Oreo's.

HOW LONG DOES IT TAKE FOR AN OREO TO LAND FLAT ON THE BOTTEM OF DIFFRENT LIQUIDS?



MATERIALS
1000 Millimeter cup
tap water
orange Koolaid
orange G2
FANTA orange soda
OREO
and metric system ruler


Hypothesis

We thought that it would take an OREO 10 sec. to land flat at 1000 ml of G2 by Gatorade co. and it would take 8 sec. for it to hit the bottom of 1000 ml of water and 9 sec. for it to hit the bottom of 1000 ml of Koolaid.

Procedure


1. Fill 1000 millimeter cup to 1000 millimeters.
2. Use regular OREO from NABISCO.
3. Drop OREO from 2 centimeters from liquid surface (Use ruler).
4. Start stopwatch when OREO hits liquid surface.

5. Time until OREO lands flat on the bottom on the bottom of 1000 millimeter cup.
6. Do NOT touch the OREO or its surroundings.

7. Repeat procedure 3 times for each liquid.


Conclusion


Our hypothesis was refuted because our timing for water was off two of three trials our closest time to the hypothesis was about ten sec. our closest time for the koolaid was about twelve sec. our closest time for the G2 was ten sec. off to about twenty sec.

Further questions

What do different ingredients do to the timing?
How fast do different cookies take to hit the bottom?

What’s the average distance a oreo can roll

Hypothesis-I thought it would roll about 2 meters. -
Materials-
1. A piece of masking tape
2. A clip board
3. A book 6 1.4 inches tall
4. Some oreos

Procedure-
1. Use a piece of masking tape to mark starting point
2.Roll oreo on clip board and a book 6 1.4 inches not standing on spine with clip board set on top
3.Do not push or touch oreo after rolled
4.Each person rolls three times
5.Start and level clip board to front of tape
6.Hold cookie with pointer finger and thumb on oreo sign
7. Measure from front of starting point to the cookies closest edge of cookie in cm
8.If oreo hits any object that roll does not count
9.Compare and find average distance a oreo can roll

Conclusions-My data did not support my hypothesis cause only one time out of three times I got 2 meters

Further questions for study-Different types of cookies on average distance roll and use different size ramps

We enjoyed out experiments so much that we have thought of a few more that we could try. Listen to our ideas!
