Scientific Observations Skills Lab

Here are the observations Jared, my lab partner, and I did.
-Copper chloride is poisonous.
-Copper chloride is crystalized and blue.
-When copper was added to water it began to slowly diffuse and turn gray in color.
-When stirred the mixture turned blue.
-When the aluminum foil was added to the mixture it slowly sank.
-Bubbles began to form on the foil then it started to dissolve slowly.
-When the water was stirred aggressively it turned gray
-The water then rose to 25.5 degrees Celsius
-The water turned into a red-like color.
-When left over night it turned a clear pale-blue color.
-When stirred it became cloudy
-When filtered it began to drip fast, but slowed over time.
-Sediment on bottom is pink.

Oreo Cookie Lab Abstract

Oreo Cookie Lab Abstract

Author: Ethyn, Pentucket H.S

Lab conducted on Sept. 12, 2013

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

Hypothesis: I believe that the advertising stating that the double-stuf and mega-stuf oreos have double and triple the amounts of filling than a regular oreo.

Method:

1. Measure each cookie with filling.
2. After measuring each cookie take the cookie part off of one.
3. Measure the mass of the cookie part.
4. Subtract the cookie part's mass x2 from the original measurement to find the mass of the filling.

Result: The chart below gives the results for this group.

                             | With cookie and filling|cookie part|       math         |result              

Original     |      12g             |4.4g   | 12-8.8    | 3.2g

                    |                 |       |                |     

Double-stuf|      15.6g    |4.4g | 15.6-8.8  |6.8g

                    |                 |       |                |     

Mega-stuf   |    18.3g     |4.4g  |  18.3-8.8 |9.5g

Conclusion- The Oreos do in fact live up to the advertisement's claim.
