Tech Blog Post #4 – Logging

Leave a reply

Today’s blog post will be about logging. Logging is the mass cutting down of trees. Back in the early to late 1900s, they used manuals tools like axes and saws, while now most to all logging is done with machinery like mechanical saws, chainsaws, and other large chopping or digging devices. Logging is used for many things. Like many of the common uses of wood, such as being used for paper, being used for building, or to be turned into products. But I find it interesting that they also use logging and the trees cut down as renewable energy.

Tech Blog Post #2 – 3D Printing

Leave a reply

3D printing is a very interesting topic, and it has been used to create several things from toys and blocks to actual artificial human limbs. 3D printing heats up a long roll of plastic and uses an extruder to put it into the place it is meant to go, using instructions from a computer. In several instances, 3D printing was used to create limbs for people born without a limb, lost a limb, or had an amputation. It is also used for things like cases, boxes, toys, even things that move, like hinges. 3D printing is a very good thing to have in this world and will be used for many other very advanced things in the future.

Building – Tech #1

Leave a reply

Building means to create, to gather materials and follow a plan, or just wing it, to create a product that has a function or is completely cosmetic. One time I have built something was with my dad when he got me a sick small homemade electric guitar kit where it had a built in speaker and everything. Another time is when I painted the nose and tail of my skateboard, and put the chemical structures of serotonin, dopamine, and adrenaline on the good chemical side, and formaldehyde, mustard gas, and trinitrotuline (tnt) on the bad chemical side. I enjoy building things even when they don’t succeed. It’s just gratifying to know that I am making something that I will be proud of either way. In my opinion building anything is really fun.

Overview and Recap of Tech Class

I had an incredible quarter in Tech. I had tons of fun with the projects, lessons, and the zoom lessons. We had only a limited time in tech, but I feel like it had been awesome and everything I wanted. I would have liked it better if we still had school because we could do more interactive projects with more advanced tools and materials. Overall, I am excited for the summer and will miss tech class and all the people in my class.

Periodic Table and Metals Lesson

Leave a reply

This is a lesson, so there won’t be much here. The first day we learned about the periodic table. It is a chart that shows all known elements. Then the next day we learned about metals. We learned mostly about conductive metals, and how they conduct electricity. The third day we learned about batteries. We learned about the reactions that happen inside to generate electricity. I don’t think there will be another project and that makes me sad, but that is ok, I’m still excited for the summer.

Tech Project #5

Leave a reply

For the fifth project in tech class we made something that I didn’t even know existed. Electroscopes. An electroscope shows if an object has an electrical charge. If it does, the two metal sheets will separate. The materials we used were balloons, one paper clip, a clear drinking glass (In my case a mason jar,) cardboard, tin foil, and a sweater. We needed scissors, and pliers. We blew up the balloon and rubbed it against the sweater to get charge into it, then we touched it to the paper clip, and the two sheets would split for a moment. The next project is gonna be cool and I am having fun in class!

Tech Project #4

This week we made a catapult! The materials we used popsicle sticks, rubber bands, and one bottle cap. We made it so that you bend back the  the arm with the cap, then release and it shoots outside of the cap. This one was a pretty cool project. I really can’t wait for next weeks project and tech class has been pretty cool so far.

Tech project #3

Leave a reply

For the third project we did in tech, we used a software called FabMaker Studio to make printable 3D guides for shaped or almost anything actually. It is a very simple program, yet it can yield some amazing results. I chose the cube net pre made project. The instructions were very simple. All I had to do was drag 6 squares into their places and I was ready to print. When it was printed, it showed me clearly where I needed to cut and fold to make a cube. This was a really fun one to do, as it was so simple.
