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.
