Skills Lab 1
Students started out with 150 mL of water in a beaker and then added 1/2 teaspoon of Copper Chloride. Then added a 15x1.5 cm piece of Aluminum foil to the solution. Then after stirring, filtered the liquid and put the sediment that was left over in a test tube. Then, Nitric Acid was added to the test tube and results were recorded.
Starting Temperature of Water: 22 degrees Celsius
Observations of Copper Chloride:
-Looks like blue sand
When Added to Water:
-Turned green when added to water
When Stirred:
-Water turned opaque and blue
-Copper Chloride dissolved
-22 degrees Celsius after stirring
After Aluminum Foil Was Added:
-Foil started to turn dark
-Liquid starting to oxidize the aluminum foil
-Foil started to fall apart
After Stirring Again:
-Foil fell apart
-Turned a rusty color
-Water turned a dark blue/gray color
The Next Day:
-Liquid is a pale blue
-Blue sediment is on the bottom of the beaker
After Nitric Acid:
-Liquid started to turn blue starting at the bottom
-Bubbling

Oreo Cookie Lab
By Tori
Date: 9/12/13
Students measured the filling in three different types of Oreo cookies to determine if the filling amounts matched the advertising claims.
Question: Do double and triple stuffed Oreos really have double and triple the amount of frosting than the original cookie?
Procedure:
-Measure the mass of each Oreo
-Take the cookie part off of one of the Oreos
-Measure the mass of only the cookie, not including the frosting
-Multiply the mass of the cookie part by 2 and subtract this number from the mass of each of the whole cookies to find the mass of the frosting itself
Data:
Original Oreo- 12 grams Frosting: 3.2 grams
Double Stuffed- 15.6 grams 6.8 grams
Triple Stuffed-18.3 grams 9.5 grams
Ratios: Original- 1:1
Double Stuffed- 1:2.1
Triple Stuffed- 1:3
Analysis:
The Oreos do in fact live up to the claims. The double stuffed Oreos seem to have double the filling, and the triple stuffed seem to have triple the amount of filling.

Do Bowling Balls Float Or Sink?
Bowling balls float because the have a density that is less than 1 g. Since water has a density of 1 g, anything less than that will float, anything more will sink.
