Skateboard wheels come in different sizes, harness, colors, and graphic designs. The first step to making skateboard wheels is with a computer design. A designer uses the software to guide cutting tools. Next the tools carve into a solid aluminum puck and transform it into one half of a wheel mold. Then the other half of the mold takes shape as the computerized tooling sculpts another puck to a profile that fits to the first one perfectly. But not all of the skateboard wheel molds are two parts versions. Others are one-piece structures each with the pin in the center to form a bearing cavity. Polyurethane then gets put into wheel molds and starts to harden immediately. To finish the process a worker loads the polyurethane filled molds into an oven and bakes them at almost 240 degrees fahrenheit for 40 minutes. Workers remove the pins from the molds and then go to the next station. At the next station, the worker blasts compressed air between wheels and the molds to pry the wheels free and pop them out. At the same time another worker probes the wheel using the durometer gauge to the urethane has cured to the right degree of hardness. If the wheel is sufficiently hard the batch is ready for the next step. The worker clamps the skateboard wheel in the lathe. The lathe then spins the wheel while an automatic cutter contours the edges to a soft and more rounded profile. The wheels get set on a tray after getting designs placed on them and then a technician will clamp one of the wheels in a testing device which will gauge the rebound. He drops the metal ball onto the wheel and measures how high it bounces or rebounds. A high rebound is desirable. And now the wheels are ready for shipping. It takes overall 3 days to make skateboard wheels. It depends on the rider for how long they will last.

Flashlight diagrams
Today in tech class we were learning about diagrams and fractions. We started out with learning about wires and negative and positive wires. We all were given diagram paper and sketched out what we wanted our flashlights to look like. After we sketched it out we measure how long our flashlights should be. Then we striped wires, two red and one black or two black and one red, after we meausre our wires we striped the top of them and made a little curve. After that we sautered.
TeamWork!!
In technology everything is about teamwork.
If you don’t work together as a team it will take a long time, but, In tech class if we make friends and work together as a team you get things done even faster!
Switches
Today in class we learned about switches. We got cardboard, hot glue, and tape and tinfoil. We made a design out of cardboard and put it together so a tin foil could touch another tin foil. We decorated them and played a switch game so whenever the two tin-foiled touch an led light would turn on. We were given a deck of cards and whenever some put a card down if it was red you would have to press down the tin-foil and when ever it was black you wouldn’t do anything. I was really fun.
Soldering
Today in tech class we learned about soldering.
We started with making a design with wires. On a peace of paper was 15 circles that we had too put a design in them. We had too do 15. We could choose and make whatever design we want. When we finished we would take the wire and put it on the design, and measure the size and make so it looked exactly like our design. After we cut our wire we took the wires and a price of double-sided tape and put the wired on the design. Then we wrote our names down on a list and waited to solder. Then we would solder and make a necklace.
SMS Tech Safety Rules
In tech we have 12 rules we have to follow. I think the technology rules are very important.
1. Slow down, think before you ask.
2. Dress responsibly No baggy clothes and dangling jewelry.
3. Don’t assume you know.
4. Power tools need concentration.
5. Protect your eyes.
6. Before using anything ask for permission.
7. Use all guards when using machines, shut off and before making adjustments unplug.
8. Power tools are dangerous, NEVER leave a tool running unattended.
9. Soldering irons are hot, be cautious soldering irons heat over 842ºF
10. Xacto knives, saw, & awls oh my be careful when handling sharp things.
11. Walk all the time NEVER nudge or push someone.
12. Report all accidents BURNS CUTS SCRATCHES & SPINTERS No matter how small.
About Effluvia
Today in science class we learned about effluvia. It’s static electricity, we took a foam sheet and a pole and put it near metal. It wasn’t just metal, it was a jar that had a swirly metal string and on the bottom of the metal was a hook that had to pieces of aluminum foil that loooked like a rain drop.
Here’s a few pictures;
Colonial day!!!!
Today is Colonial day. Colonial day is when we dress up in our fancy nice costumes and look like colonial people. I went to school well first it was early morning first and I we played music like always but today we put on our colonial costumes. After the bell rang and everyone went to there class and we saw everyone in there costumes. Right, when we went to the class we got an activity it was a maze and a word search. the word search was easy but the maze was so hard. After that we had someone come in. It was someone that was pretending to be a colonial teacher. It was so funny, She made us do a spelling bee but she gave the girls easy words and the boys got hard long words. Whenever you got something g wrong she made you hold up a sign saying Idle boy or something else and a Dunce cap and other things like holding chairs. After that, we wrote on a piece of paper and we wrote with quilts. If you don’t know what a quilt is it is a feather with a sharp end so you can write with ink.
After that we went to a different class and we did tinsmith. Tinsmith is when you get a tin plate kind of like a pie shape. They people in the class room gave us choices to what shape we should do. I picked corn. So I taped the paper to the tin and I Got something sharp and pocked the holes from the paper. After a very long time I did my own little design on the side. Then I took the paper off and looked at the whole picture. It was so cool.
Then we did candle making. We all got strings and put our name on it and make them even. Then we got in a line and on a table they would have two buckets of wax and 2 buckets of water. You would dip the strings into the wax then you put water on it and do it one more time.
Then we went down stairs to do games and riddles I to pick up sticks. Then riddles then we had to try to get a hool a hoop to stand up while we push it with a stick. Then dancing. We went to the chorus room and we got in a line with a partner my partner was Stella. This girl sand colonial songs for us and we danced to them. We did 2 dances. We went back to the class and did music. We sang songs and learned about new instruments. Then we went to lunch. again we went in the chorus room and we took food there was chicken, mashed potatoes, vegetables, corn, and so much more. After everyone was done you got dessert. There was pie, whipped cream, and so much more. Then we did the dance with the rest of the 4th grade. and with my mom we did the floss the dab the nay nay it was so fun. and that was colonial day. I hope the rest of fourth grade enjoyed it and you too.
Science Lesson 16….
Today we science tested our landscapes ours worked. My group didn’t exactly predict how the landscape would react to the landscape but if I could predict I would predict that it would be successful. If this was real life in a actual dam area I would locate it in Jamestown, Virginia because Jamestown is a very poor unhealthy
Wayside Cottage!
Today we went on a field trip to Wayside Cottage. Wayside was built before George Washington was born. So that means it’s about 100 years old. It is a old colonial house place it was a meeting room, keeping room and so many other things. It is where there was a family of 8 children and 2 parents. I know its crazy right. Well any ways back to what we did. First we went into the meeting room we learned what a proper colonial family does. 
This is the meeting room (it is very small)
Then we put on actual colonial costumes it was so fun we were dancing and laughing (We were just dancing with our friends). we ate corn bread and drank apple juice and we took some pictures. We also learned about how you would get the mail. Who ever wanted to send the mail in these days the person who wants to send it pays but in the 1700’s the person who got the mail has to pay. If your wondering how much it depends how long it took. Here are the pictures.
