Self Evaluation: During this activity I learned a lot & The reaction of the antacids & the vinegar was fun to watch. The lower the Ph Number the more acid something has. Therefore, the higher the numbers get, the more the solution is a base. An antacid is a base so it balances out the Ph level making you feel more comfortable when you have a lot of acid in your stomach. I learned that different antacids effect some PH levels different while others don't. I wasn't aware that vinegar has a similar PH level as stomach acids or that the antacids work as fast as they do. Just because some antacids are labeled "maximum strength" or "extra strength" doesn't really mean they work any different then the other. In the end, I did learned not to use liquid antacids before Tums because it won't work! (:

Antacid Lab

Properties of Water!
The class performed a water lab in groups and I had tons of fun! (: We tested a variety of things as far as: how many droplets of water or alcohol a penny would hold before it spilled, the form water takes when it's placed on a sheet of wax paper, and also how far water can travel down a string without hitting the floor before it gets into the cup.
Here's just a cool picture I created on wordle with a bunch of words related to the topic(:
- As far as the water on the penny, the highest number one of my group members got was around 35. With the alcohol, the highest number was 27.
- Water was placed onto the wax sheet. When we attempted to cut the drop apart with a toothpick, it just moved around the paper.
- In order for the water to travel down a long length of string you had to wet it. My group, of course, wanted to break the record (: so we took just over the record holding amount and attempted it! We got water about 3/4 the way down before it spilled onto the floor. Before we had another chance to try again, the bell rang. BUT, we were suprised at how far the water actually did travel without hitting the ground.

‘Dead simple’ way to see atomic structure
Soooo.. Here's what i learned! :D
Researchers believe water coats just about every surface at room temperature. So with just a sheet of carbon reasearchers have found a new way to visualize the structure of the molecules. The water molecules are hard to study because they are always in movement but, by accident a group found a better way to look at these molecules. They discovered that Graphene, a honeycomb like lattice, should be flat when layered onto a flat surface. This proved that water molecules exsist on every surface :D They tested further and discovered the water molecules' pattern became more odd at a higher humidity. This also supported their idea that the molecules exsisted on all surfaces. After performing this experiment, they discovered the molecules form in a two layers of two-molecule-thick of ice forms. On top of this is where you get your droplets. As they work further they are trying to make is possible to photograph these molecules.
Self Evaluation:
I would just like to point out I wasn't aware of ANY of this. I learned a lot! I would like to work more with articles and summarizing them because I'm not very good at understanding things when i read them. I have to have a visual picture. Although, I did learn a lot from this article.

Clinical Trials (:
http://photopeach.com/album/17kscxl#
Since I wasn't able to get the video embedded into my blog your going to have to copy & paste to watch my video of a clinical trial! :D
Self Evaluation:
I believe my strongest area would probably be standard 6 because i used appropriate technology. (: My weakest area would probably be standard 8 only because sometimes I have a hard time at recognizing my weakest areas, especially in science. Therefore, that's what I'll be working on :]
