Journal: 2-18-2008

I went to the science fair. I memmerysed how to spell Chocolate! The titel of my science projekt is: How Much Energy Do Foods Contayn? I used 3-D paper. I love SCIENCE!

I like playing play stayshton [Station].

I like playing in the snow.

I like dooing beads.

I like Scooby-Doo.

Friday Stories: Laws Aren't Fair to Kids

I don't think it's fair that you have to be 18 to vote and when I'm 18 there won't be a presidential election, so I'll have to wait until I'm 21. Some adults don't even do research on who they pick, they just pick it if they don't know. If I could change the laws, I would change it to "you have to be eight to vote."


I don't think it's fair that you have to be 18 to buy lottery tickets because I know there's billions and billions and billions of people trying to win, and I'd be very surprised if I won. I just want to do it because it sounds fun. I'd change it so that you have to be eight, also. I'd leave the one that you have to wait until you are 21 to drink beer. 'Cause beer can damage your brain, I don't know how though. Your brain is done growing when you're 21 so I'd leave that one.


I think you should be able to drive when you are ten. Well, whenever you are tall enough to reach the pedals and see out the window. And when you learn to be a safe driver.


When you collect sales tax when you sell something to someone, you have to give it to the government. I don't think that's fair 'cause the governments are so rich, they don't need our money that much. The government should set aside some of their money for interest. That's another way for them to earn more money easily. If you have a million dollars, and put that million, all of that, into interest, you would be getting paid six dollars a minute, and ten hundred dollars a week. You'd be so rich, you could live on your interest.

My Science Fair Project Abstract

A calorie is a unit of energy. One calorie can lift a 70 kilogram (155-pound) person into the air 6 meters. Sugar in a different source of energy is more powerful than dynamite. I know two calorimeter types. A can calorimeter and a bomb calorimeter. The point of a calorimeter is to see how much energy is in foods. A bomb calorimeter is like a can calorimeter although you blow up the food instead of burning it. You dry the food up for the bomb calorimeter and you grind it up so it doesn't have to use up some of the heat energy to get the moisture out. Then you use pressured oxygen and it's shielded by a steel dome with a water bath.

A can calorimeter is put on a ring stand and you use a clamp to hold your food in place. Then you burn the food and however much the temperature of the water rises is how much energy was in the food.

We burned ten different kinds of food. We burned cherry sours, apple, carrot, Pirate Booty popcorn, Mentos candy, Fiber One granola bar, peanuts, pistachios, provolone cheese, and a Hershey bar. I only picked foods that I liked. First we had to get the supplies. Then we weighed the foods in grams. We used gram weights. We used a balance scale. We burned one food at a time. The food that took the longest to burn was the Fiber One granola bar. The Fiber One granola bar burned for exactly 16 minutes and 5 seconds. The provolone cheese had some reactions that looked like a sparkler. It shot out blue sparks. The provolone cheese stinked the most.

I was surprised that the peanuts raised the temperature from around 15 or 16 degrees up to around 95 degrees Celsius. One hundred degrees Celsius is boiling. Even though the pistachios didn't reach 100 degrees Celsius, they still boiled.

There are two different kinds of calories. Science calories with a little "c" and food Calories with a big "C." One food Calorie is worth 1000 science calories. It takes 4200 joules to make up for one food Calorie. You use joules to figure out how much energy is in foods and how much work you can do with a certain amount of energy.

The carrot was the most fun food to burn. It was the easiest to do. The chocolate was kind of hard. The pistachios I did for a little bit, and oh, they lit on fire so easily!

I wrote observations about the foods we burned. I wrote the observations myself. I wrote about what I learned while doing the experiment. I memorized how to spell chocolate and observations. I'll tell you how to spell chocolate: c-h-o-c-o-l-a-t-e. I also thought of the hypotheses by myself. I guessed that the slower a food burned, the more energy it would have. I was right. I wrote all the foods that we were going to test. I wrote a list of supplies we needed. I wrote the numbers in the tables. I did all the measuring for the experiment. I measured how long the foods burned. I measured their weight before they were burned and after they burned. I measured the water temperature, too. The coldest it ever got was 15 degrees Celsius. I measured 50 ml of water. Every time we burned a food, I had to get fresh water.

My mom made the tables on the computer. Mom printed the papers for my display board.
Mom made the books and lists of websites we used.

The hardest part of the project was writing. It's hard for me to do that much writing. The experiment was easy for me to do.

If I do this experiment again, I would use a candle instead of a lighter so we wouldn't run out of fuel right in the middle of the experiment! I would use a different calorimeter to get a more accurate answer. This calorimeter let some of the heat out through and into the air. Next time I would try the foods a few times to see if it actually burns that long, and to see if the flame was hotter or colder. I would test out marshmallows next time. I could use different kinds of nuts next time, like Brazil nuts, walnuts, coconuts, and macademia nuts. That would be interesting. I would measure the water level at the beginning and the ending of the experiment if we did the experiment again because that could affect our answer. It takes energy to make the water evaporate and I would need to measure that energy.

Friday Stories: The Snow-Burning Snowmobile Shoes

Once Mom took me to a shoe store and I said I could pick out anything I want and I found a pair of shoes. They had a little conveyor belt built in that worked like a snowmobile. They were only eight dollars. Mom said yes.


And what luck I was in! It was winter when Mom bought them so I got to try them out and I said, "Slow!" it went slow. When I said, "Medium!" it went medium, and when I said, "Fast!" it went fast. I loved making jumps for my shoes and doing stunts on the jumps.


Once I entered a contest What Was the Fastest in a town called Waseca. The pond was a mile long. The judges said I lost but actually I went up so high on a bump and I accidentally turned around the other way. I was three-quarters of a mile there. I was heading right toward the starting! Then I turned myself around and then a foot before I got to the finish line I hit the ground, and boy, that was the funnest jump I ever did.


The prize was one million dollars. I put it in interest, so I'd be getting paid six dollars a minute and ten hundred dollars a week. I chose to impress Target and I sold them out of Game Boy games. Then I gave a quarter of the Game Boy games to Mitch and then I sold some of them for fifteen dollars each. Accessories were five dollars. I earned one hundred dollars.


I donated ten hundred dollars and [Mom, what are those bell-ringing things?] I wrapped up a check for ten thousand dollars in a one dollar bill and gave it to the Red Kettle for the Salvation Army. [We read a newspaper article about a donor who donated in that manner during the holidays of 2007 and Max was most impressed.]


And then I decided to impress Target again by selling them out of Air Hawk toys and Nerf Toys. I bought the newest dart gun from Nerf. It's twenty dollars and it's the newest dart gun in Target made by Nerf and it has laser point action. I sold them out of that and the glow-in-the-dark dart guns.
