Periodic Table

In class right now, we are learning about the periodic table. Therefor, I thought I could post it on my blog.

Vinegar Poppers Lab - On the Next Day....

Friday was the final day of the vinegar poppers lab. On our tenth, in totaling both days, we finally hit the window. However we didn't manage to hit it three times in a row. Our distance sarted increasing when we sparked with a different idea. We mixed water and baking soda together. Then we poured this new solution into the vinegar. We noticed that our distances were much farther. Eventhough we didn't hit the window three times in a row, I am proud that we did once and the lab was a lot of fun. I hope we do something like it again soon.

Vinegar Poppers Lab

Just today, we started a lab where we combined baking soda and vinegar to create a chemical reaction. This chemical reaction created carbondioxide which made a cork fly off a test tube.

When we first recieved this lab, many thoughts were being juggled around in my head. I was anxious to start our lab because it sounded a lot of fun. I personally love messy labs. Our goal was to get the cork to hit the window three times in a row. To accomplish this goal, we needed to find the correct proportion and an accurate launch projection.

This lab looked pretty simple, but it was not as easy as it seemed. Two groups, in my class, hit the window once. The farthest our cork went, in seven tries, was 510cm. Our cork needed to travel 210cm more to reach the window. Our measurements for the best distance was approx. 6mL baking soda (NaHCO3) and approx. 25mL vinegar (CH3COOH).
According to our results, we realized there needs to be more vinegar than baking soda, but not too much. In this lab, sometimes less is more.

I personally really enjoyed this lab. Even though we didn't hit the window, it was a lot of fun. I entirely enjoyed myself. I'm looking forward to figuring out the exact measurments in the lab tommorow. Hopefully we hit the window three times in a row tommorow!

Extra Credit

One of my favorite T.V. shows is Suite Life On Deck. I havn't watched it lately, but over the summer, I watched it like everyday!

In one episode, Zack creates an explosion and the ship starts stinking horrible. I realized that Zack's explosion was a chemical reaction. In class, I remember learning about how chemical reactions can create explosions. In addition, connecting to what we are learning now, his explosion was a chemical change. Meaning, a substance undergoes a change and a new substance is formed.

Obviously in the episode, the whole thing didn't focus on chemical reactions or explosions. Zack was given the job of hall monitor, and he bacme very snobby. However, that is a whole other story. Who would have a show like "Suite Life On Deck" could connect to science.

Mini-Connection

Have you ever baked or cooked something before? Well, guess what! It is all related to science. Baking and science are connected in many ways. Just imagine. Who would have thought of baking as a science? When you bake, you are changing the chemical properties of a substance by heating it. A chemical property describes a substances ability to change into a different substance; a chemical change is the process by which the substance changes. Chemical reaction is another way to say chemical change. In class this afternoon, I realized that all baked and cooked goods are outcomes to a chemical reaction. In addition, when you bake you may also use formulas. Formulas are definitely connected to both science and math. Who knew you could think of baking as a very important science?

I used the the Textbook...

Quote

" In Science the credit goes to the man who convinces the world, not to whom the idea first occurred." This meaningful quote, said by Sir William Oslar a Canadian physician, is very true. I completely agree with everything this quote has to say. In science, you must be able to prove to the world that an idea is real. Only then, will the world be able to appreciate the idea. Anyone can think of a mere idea, but it will only have value once it is proven. The idea is like the hypothesis or an opinion of what you think. The world can not come to your feet and start calling you a genius for having an idea. You need to support your idea with proof. Like our lit. teacher teacher always says, "justify our answer/idea." Putting it out there is not enough. For example, Galileo's idea was that the world was round, but no one believed him at first. He was almost categorized as a crazy. We appreciated the idea after we had proof.
