Timber Harvest

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.
