Mini Project

So Kimberly Arciaga and myself were thinking..."What would be a simple but fun experiment to do?" and we thought of the best one!!!! The "Cup, Water, and Index Card "experiment.

What you need:
-plastic cup
-sink
-index card

Instructions: fill cup with water until it is almost full, put the index card over the cup, turn over the cup (while holding the card in place), then let go of the card.

The card doesn't fall?! how wierd!!!!!!!!!

Explanation:
In the "Cup, Water, and Index Card" experiment, the water can't escape until the card is out of the way, but for the card to move, the air inside the glass has to get bigger. The pressure of air outside the glass pushing up on the card keeps it in place.

I Propose We put a gummybear into a test tube of potassium chlorate!!!

I propose we put a Gummybear into a test tube with potassium chlorate inside of it!

Links: Potassium Chlorate- http://www.chenzhoumetal.com/Potassium_Chlorate.htm

Gummybears!! - http://en.wikipedia.org/wiki/Gummi_bear

Materials: Package of gummy bears, goggles, medium sized test tube, potassium chlorate, bunsen burner, ring stand and clamp, and tongs

Procedure:
1.) Place test tube in the ring stand and clamp over a bunsen burner
2.) put potassium chlorate inside test tube
3.)heat the KClO3 in the test tube until it is a molten liquid
4.)place the gummybear inside the test tube with a pair of tongs and watch the gummybear go bye bye!!!

Safety Precautions:
-wear goggles
-no loose clothing
-keep face away from the open end of the test tube when reaction is taking place
-do not touch anything hot
-Be careful and have fun!

Principles:
The gummi bear is mostly sugar, which is oxidized by something like molten potassium chlorate. A balanced equation would show sucrose (C12H22O11) being converted to carbon dioxide and water while the KClO3 becomes KCl. The actual reaction does not seem to go to total completion since there is usually a little gunky residue left behind.

Watch what happens!

Vacum Society!!!

So David and Joan Webb from some science place that dedicates their studies to vacumes came to our class on tuesday. They were an elderly couple and they were very nice. They were explaining that the vacume reduces pressure to a lower pressure than atmospheric pressure. It was very interesting to learn about vacumes, and I got to show off my common sense knowledge for the class when he was asking questions =P. I learned that there is no such thing as a perfect vacum. In the sports world though, we had a track meet today and I did really good. I got first place in long jump, 18 feet 5 inches, first place in the 400, third in the 200 and first in the 4x400 relay. It was very exciting and I felt really good about the meet

3/15-3/20

So I was stressed out this week because I was deciding wether or not I should do football or not, and I think I have some legitimate reasons. I really want a job this summer, and if I do football then I am not going to be able to have any time for myself because of summer conditioning. I also feel like I wouldn't be doing it for myself, I feel like I'm going to be doing it for my friends and that isn't right. I could go on all day, but the point is is that I've decided football isn't for me. Soccer is my LOVE!!! I'm going to find a class 1 CY team for summer and go on tournaments around the state. I'm getting jealous of my best friend because he's been going on all of these tournamens and he is in San Diego as I speak, for a tournament. And another friend is at the State Cup!!! A few weeks ago, he played the Idaho State Champs and tied them...I've been getting soooo jealous, so this summer I'm going to focus just on soccer.

I have been a little stressed lately because of my parents, they're just getting on my nerves and it's getting to me. I have started track and today is my first meet at Terranova, I am very excited because I am a very good runner and I'm sure I will do excellent. Chemistry is hard!!!!! it's not fair! It doesn't make sense at all!!!! My brother and I went on our first snowboarding trip this weekend and it was amazing, we went to Tahoe and snowboarded with his friends, it was awesome, It was warm the whole time we were up there.

So I havn't blogged for over a month, and I don't really have a lot to say!!! Soccer has been in full swing and were having an okay season. I have 3 goals, and many many assists, you can look at the PAL standings at http://www.smcoe.k12.ca.us/pal/. I'm doing track and football next, so Im going to be very busy in the coming months :)

Like Dissolves Like

Like dissolves like means that substances are more likely to dissolve in other substances with similar chemical properties. It is most often used when discussing polar and nonpolar solvents. For example, oil will not dissolve in water because oil is nonpolar and water is polar. Basically, a polar solvent will generally dissolve polar solutes and sometimes ionic solutes, and a nonpolar solvent will generally dissolve nonpolar solutes.
