There were certain things we learned. Cams/mechanics and the electric board, the automaton, and a catapult. I learned that the triangle is the strongest shape because aside cannot change unless the other side changes. I learned about automaton and the functions it could do. I learned its history and learned some of the most famous ones such as the boy writing a letter. I learned how to make a catapult out of popsicle sticks and to launch them. I learned how to cut off the outer layer of the wire to just leave the middle in there for the electric boards.  I learned that the fulcrum is the point where you move something and the point does not move. Finally, I learned about the cams and cranks that could create a function for the automatons and could make something look real. I learned so much in technology.

First, fold part 8 to have the square on top and circles on each side and with the back covered. Next, fold the top of part one back that makes a hole. Make sure it has enough to fit something through. Next, read parts C and D.

. Then, stick the ends of the piece through the circles from part 8 and the tall part through the square at the top. Fold out the flaps of each side and face the open side towards you. Put part 10 on the left, glue on the flaps and open the flaps on piece 9 and take the flaps from part 6 through it and glue the flaps from piece 6 onto the back of piece 9. Finally, glue the flaps on to piece 7 with the squares matching up and glue piece 11 to the bottom.

Bonus!: Put a animal or Human drawing (or together) On top to make it look like there moving.

First, fold part eight to look like a box with the square on top and circles on the sides with the flaps glued down. Next, take piece one and fold the bottom out, and put it through the square on the top with the flaps glued to the top of the ceiling of it. Next, fold the flaps and paste them onto piece three where there are the dots. Next , read parts D and E

Next, face the open side towards you, glue part ten on the left where the square is and glue piece seven on the right with the flaps outward and with the flaps from piece 6 through the hole. Finally, put piece 11 on the flaps from part 6 with the square in the middle matching up with the square on piece 11 and glue piece 7 on the bottom.

Bonus!: Add an animal (Fish etc,) on top to make it look like its moving!

You need 12 popsicle sticks,3 rubber bands, a bottle cap, and some glue. Stack 10 sticks on top of one another. Then put one stick through to make it look like a cross. Then tie a rubber band on each end to hold it together. Then put one stick on top of the stack and the one through the middle and connect the tips of each stick with a rubber band. Finally on the same stick, get any bottle cap and some glue. Squirt some glue on the tip of the stick. Place the bottle cap on the glue and gently push down and wait for one hour at least (a few hours would be better though).

Bonus: Game 1: Get a piece of paper and draw a bullseye and the middle is ten points, next level is 5 and after that is 3 or 1.

Game 2: Use your catapult to annoy your little siblings. I highly recommend something small or soft like a marble because it is small.

The results are in! My truss project full of triangles was able to hold a lot of books. It held nearly 10 medium-size books. I knew that the strongest shape is a triangle so I added the supports to be all triangles to make sure that it held up nicely.  I also built a catapult. The catapult is made out of popsicle sticks, rubberbands, and a bottle cap. It does not matter where you put the bottle cap on the first half of the slanted popsicle stick because it will go the same distance. It also barely matters, if at all how much you push the slanted stick back to any angle. Numbers: From the effort arm tip to the fulcrum(the bottom) is 150mm. The Load to the fulcrum is 100mm, 150mm/100mm= 1.5 mechanical advantage. The catapult can hit about 3 ft long and a couple feet high and can fit up to about 3-5 marbles depending on positioning.

To create a project like this you first have get lots and lots of toothpicks and get carrots. Chop them up with a knife into pieces/squares. Stick the toothpicks into the carrots and then make your own design. My design was simple but stable. I had three equal triangles on both sides, a square at each end, slanted, with a couple of toothpicks taped together to put across it to make it two triangles. The top and bottom just long rectangles. To make a stable design, it should be wide and long. Triangles are the strongest shape so create a lot of triangles as supports to make it more stable. When taping two toothpicks together, try and keep them tightly and neatly wrapped around so they don’t fall apart as easy to make them more stable. Lastly, The carrot pieces should be about 1cm wide, high, and in length to be able to stick three or four toothpicks and be able to adjust them without breaking up the carrot piece.

I tested my custom beam to hold the weights up in the bag with the beam holding the handles. I first tried 3 pounds and it held up. I tested 6 pounds and it collapsed. In conclusion, I think that it should have been able to hold 3.1-5.5 pounds. I tried the I beam and it held for both 3 and 6 pounds. I then tried 7 and the 14 and it still held up. In conclusion for the I beam, I am able to hold over twice the weight of the custom beam and maybe more as it still did not collapse. I think that my custom beam fell because the lines on it go vertically making it flexible and easy to bend which is why it broke so easily. The I beam on the other hand had the cardboard holding it made sure it could not able to bend.

The I beam is shaped like I. In order to make it your first going to get to two-inch-wide pieces of cardboard. Next, you pull the sides up into a U shape. Do it for both and then stick the underside of it to each one by gluing and it makes an I. Let it dry for an hour. I put another strip of cardboard that fits the width and length perfectly and let it dry for an hour. You can use rubber bands or tape to hold it together while it dries. When it is done it looks just like a 3D I. My custom design is 4 stacked 12 by to 2-inch pieces of cardboard stacked on each other. My design is simple but I think compared to the I beam it will hold up better because the I beam has less mass and is made of less cardboard while the custom-built beam has more mass and is made up of more cardboard and I think is sturdier.

I learned in tech we learn about many things about just tools we use in our day-to-day life and we are learning such as the structure of objects and other robotics such as cams. I also found out that we are learning about electricity. This class reminded me of a science camp I did a couple years ago. We were constantly doing 1 project a week and working on that a lot of the time or just about the topic of the week. My prediction about tech is that it will be similar to my science camp that where we have a project and we learn about that topic that the project is in and work on one project a week. In the submissions form where it asked what one human invention could we not live without. I then chose electricity because almost all house appliances and other things such as lights, heating, air-conditioning, and you can’t charge your iPhones, you can’t turn on the tv or charge/use a computer/laptop unless you have a portable electricity machine. When I found out that we were learning about electricity I was very excited. I think we are going to build our own circuits and build more complex things. For structure/building we might build something like a catapult or some other structural things. Finally, another thing I learned is that how we are having one project per week like this week is a nearpod.

In my Tynker project, I tried to make Cody ask questions. I made Cody ask questions all about state capitals. I looked at a few and I really liked Noam’s. I liked how the project had added sound effects such as music if you got it right or wrong I found out that the capital of Italy is Rome. I also liked that you had an introduction at the beginning asking what your name. Finally, I also like how the project had little facts in between each question such as The largest capital city is Tokyo at 6993 km squared which I found interesting.
