In tech we watched a video about timber harvest. In the first video I learned how they used to cut down trees. They cut down tree electric saws so it will take a shorter amount of time. In the second video, I learned how the job of a woodcutter can be dangerous if you are climbing trees or a tree falls on you. In the third video, I could see the difference in how it was more modern. I would want to learn more about the automatic tree cutting machine they used. Finally, in the fourth video I learned the steps of a woodcutter’s job. Overall I liked learning more about trees.

3D printing
There are many benefits to 3-D printing, but most important is that it changes the way we make things. First, 3-D printing helps to make things in a more cost efficient way. For example, in China they used 3-D printing to build houses for people. According to the video, they printed 10 houses for less than $5000. Another example where 3-D printing changes how we make things, is in the medical world. For example, doctors are using patients’ cells to make plastic ears, noses and organs for transplant. Certainly 3-D printing is helping people around the world.
Building
The first week for 7th grade technology we are working on building. Building is mostly having wood and glue then making something. Yes, it is that but there is so much more to building, like using your imagination, creative and knowledge. One time at camp I had to build a bird house with no instruction and I had to think of what to do but I had to figure it out. I did it using my knowledge and it worked.
Week 6
In week 6 the project we made was catapults. During the week we mostly talked catapults. We could make them out of popsicle sticks, rubber bands, and a bottle cap. This is one of our final projects.
5th Day of Tech
Fourth Day of Tech
For the forth day of tech we made a canon. We had the option to make it out of popsicle sticks or sticks or plastic knives and spoons and rubber bands and a bottle cap. I thought it was fun but a little complicated.
Third Day of Tech
This week in Tech we had to build. This week project we had to build with toothpicks and carrots. I didn’t build with carrots, I built with marshmallows. With the toothpicks and marshmallows I had to make a 3D square. Next I put it in the freezer because it kept breaking. Then it started to work.
Second Day of Tech
For this week for tech we made something. I was fun. We made a I beam. I beam are used everywhere. A I bean is something that supports trusses, or near the ceiling in buildings or on bridge. In a bridge there are different shapes.
First Day Of Tech
I’m just learning what interesting things we get to do in 6th grade tech. In tech we get to make all different things that we will have in our house. For example, one thing is a flash light. There are many thing we will learn and I can’t wait to share them all.
