Experiment-Coin Lab

On the 3rd of February,Thursday,2011, we did an experiment. What you had to do in the experiment was to put how many drops you can on a penny or a 5-cent euro coin. Here is what we needed to do.

Part A:
Step 1: Rinse the coin and dry it completely.
Step 2: Place the coin on a dry towel.
Step 3: Use an eye dropper to place drops of water on the penny (one at a time) until ANY amount of water runs over the edge of the penny.
Step 4: Record the number of drops for that trial in the table.

There was also a part B.

Part B:
Step 1: Rinse the coin and dry it completely.
Step 2: Place the coin on paper towel.
Step 3: Hold the coin with the tweezers provided, then dip it into the testing liquid (water). Allow extra liquid to drip off the coin into the container before going to the next step.
Step 4: Place the coin on a dry spot on a paper towel. Place drops of water on the coin (one at a time) until ANY amount of water runs over the edge of the coin.

Part A:

Trial 1: 44 drops

Trial 2: 24 drops

Trial 3: 27 drops

Trial 4: 48 drops

Trial 5: 17 drops

Mean (average): 32


Part B was better than Part A.

Part B:

Trail 1: 61 drops

Trial 2: 56 drops

Trial 3: 201 drops

Trial 4: 72 drops

Trial 5: 32 drops

Mean (average): 100

What Is Balance? Do You Need Balance?

Balance means to keep balance of the things you do.

For example, 

Suppose you are a academic student. You always get good grades and you are great at math, science, social studies,etc. And you have lots and lots of friends, you play skip rope, you can sew, you can cook, and you can do many other things. That would be an example of balanced.  

I do not really know if I'm balanced. I have lots of friends, I play sports, and I have many talents such as dancing, reading, painting,etc.

But, I am also get good grades, finish my homework on time, read everyday,etc. 

Sometimes I can focus on one or more things at a time!

Ads-5th Grade

On Thursday, the 19th of January, 2011 5A and 5B had to present their ads in front of 5th grade. The first one was Juicy Juice. It was by Lana, Nemke, and Max. They all did an ad about juice.


Juicy juice:

The actors did not speak clearly.

The music was too loud.

 I could not understand what they were saying.


The logo was colorful.






I think Fizzy Rawr(from 5B) was the best because they not only make their own jingle but also tried to make it unique.
