SCIENTIFIC OBSERVATIONS

 

 

 

I was absent for this experiment 

Oreo Cookie Lab

Lab conducted on September 12th, 2013

Students measured the filling in three types of Oreo cookies to determine if filling amounts matched advertising.

Hypothesis: The amount of filling in the Oreo does not match what is advertised.

Method: weigh all three types of Oreos

              weigh one side of the cookies out of 2

              double the results

              subtract from results of step 1

Students peeled filling from different types of Oreos- Original, Double- Stuf, Mega-stuf- massed each and compared results.

Results: Chart below gives results for this group:

cookie part mass: 4.4g

Cookie                  Mass             after mass of cookie part is subtracted

Original                 12g                     3.2g

Double-Stuff         15.6g                  6.8g

Mega-Stuff            18.3g                 9.5g

Conclusion and analysis: The amount of filling in an Oreo does match advertisement.

What I Learned This Week

This week we learned a lot about measurements. For example, we learned to calculate density, volume, and mass. We did a Do Now everyday which prepared us on what we were working on in that class. When we found out if bowling balls sink or float, we learned about density and how anything less than 1 floats.  I was not here for the gummy bear lab so anything I say can be incorrect. But I think we used that lab to learn more about measurements. Like how to calculate volume of abnormal shapes through water displacement.

Why Do We Study SCience

Why do you want to take this course?
I took this class because my math grade was too low to apply for chemistry.

What do you hope to gain from this course?
Enough credits to graduate.

Why is Science important/ why study science?
To answer questions we have about the world/ life.
