You are about to see the observation/experiment segments of this experiment. I'm sorry If it's a bit out of order but in Part III you will get to learn about our hypothesis and other info I left out in parts I and II. So here it is:
Below is the Silver Nitrate and Sodium Hydroxide Precipitate experiment about a minute after it was stirred. You can see that the Silver Nitrate dissolved and how it looks to be nothing but harmless water. But also note that drinking it could result in a severe belly ache- and most likely worse consequences.
To the right you can see the beginning of the Copper Sulfate and Sodium Hydroxide experiment. Look at the odd bubbles at the bottom of the test tube!
Here's Mr. Harrelson "stirring" the Copper Sulfate and Sodium Hydroxide experiment.
Above we have Mr. Harrelson closely examining the experiment while Mary Grace and I (out of frame) have our fingers crossed that something will happen in the experiment... We are not very patient.
Above we have the Copper Sulfate and sodium Hydroxide experiment... This is a great picture because you can really see the basic 4 layers in this experiment. First there is the condensed water on the sides of the glass, then you can clearly see the Sodium Hydroxide that turned blue from the Copper Sulfate, next comes the putty-like layer where the two ingredients creates a solid- thus completing the bit of the experiment that give it the name "precipitate" experiment (see part I), and finally we can clearly see the pieces of Copper Sulfate that did not dissolve*.
Below is the Silver Nitrate and Sodium Hydroxide experiment, and while it is not visible in this picture, there were little specs odd some kind of solid forming at the bottom of the test tube. They looked like EXTREMELY fine grains of white/transparent sand.
To the right and below
are the two experiments
beside each other.

To the left you can clearly see the large amount of condensation of the Copper Sulfate and Sodium Hydroxide experiment.
And here you can see the Copper Sulfate and Sodium Hydroxide experiment from and aerial view. Doesn't I appear to be glowing? :)
*Note that we were inspired to do this experiment from this video on YouTube: http://www.youtube.com/watch?v=JAeOP2MfrDY&feature=related
and didn't notice that Silver Nitrate and Copper Sulfate are not normally in liquid form... So while our experiment did create solids, it was technically not two liquids creating a solid and so we failed. :( But in the process we did learn what precipitate experiments are- which is good even though (due to bad planning on our part) we did not execute the experiment properly.
