In tech we learned about atoms. They are so small. If you had a ball of nitrogen atoms the size of a grapefruit. You would have to make it the size of earth for the atoms to be the size of a blueberry. In the middle of the atom there is a nucleus. I the nucleus there are positively charged protons and neutrons that have no charge. Protons don’t like other protons like when two girls were the same dress. The neutrons are there so the nucleus can stay together. On the outside there are electrons. They are negatively charged. They are more in a cloud but we draw them differently.

Today I finished my automaton. It uses a Cam mechanism. When I turn the paper circle the cams spin. Since its not a perfect circle it pushes the thing attache to the dolphins up. A lot of things use this. Most cars uses this inside of the car. One challenge was making it so what goes up and down doesn’t rub against something so it goes up and down.

Today I made a structure out of tooth picks and cellularly. The assignment was that you had to build a structure with toothpicks and something else to hold them so I chose cellularly. You also had to incorporate so trusses. Which is a triangle. He made a cube with carrots and toothpicks. He put books on the top and his was able to hold 5 books. And when I put books on mine it could hold 7. But I had to rebuild to get the test on video. This time it could hold only 5 . So I kinda won.

Today I finished building me I-Beams. I made one by watching a video Mr. Calvert made of him making one. And the other one I made by myself. I used tacky glue to make it. Twenty actual minutes later. Welcome back I just finished testing my I-Beams. I put the handles around the I beam and put the I-Beams on a chair. I put 1 inch of slack over the chair. I put weights in the bag. My I beam was able to hold 21 pounds. His was able to 25 pounds. So his won.

On Tuesday we learned about the property’s of materials and how heat And cold can change them. First we learned about the Titanic, the Dee bridge, and challenger a space shuttle. We learned about how they all broke even thought they used very strong materials. Then we talked about the different forces they might encounter. Mr. Calvert talked about how different materials have different properties. Like Cement which is very strong but easy to pull apart. Then we watched a video that showed a rod of steel be pull apart with a machine. He showed us what was happening and how steel is very ductile. Which means it is hard to pull apart. Then we learned how heat and cold could change the property’s. When the Titanic was on the water some of the iron froze. So when the iceberg hit it the iron shattered and made a huge hole. Also the dee bridge collapsed because iron broke from the vibrations of the train. And the challenger space shuttle vaporized and failed. Part of the rocket froze and made it break. And killed all the passengers.

When creating wellness log Each time I did an activity I would right is down and when doing Friday I knew what I was going to do that day. For the totals I went and hit equal sign b2 plus b3 plus b4 plus b5 when putting the cells I would click on them. For the average I put average and put the cells.  I think I could use this for weight lifting to see if I am making progress.

The sheet shows the amount of home runs team hit. Each row is a different year and each column is a diffrent team. The new Column I added shows how many more runs a team hit. If it’s blue that hows many more the Yankees got. And if it’s orange it’s how many more the Mets hit. The formula I did was C minus B whatever row it was.

Things that was hard with righting the codes was getting it right. If I was talking to a person I don’t have to say show (“hello”) but with the coding you do. Because the computer is not smart enough to always know what you are talking about. Also I thought it was fun when you finally got it correct and it felt great.
