History of Table Saws in Teaching- It wasnt until after World War 2 that industrial technology education really took off. So it wasnt until post war that school would have seen these tools or the table saw in their schools across the country. The first saws were often very dangerous so this would have prevented schools from using these as well. Current use of Table Saws in Teaching- The current use of table saws in teaching would be in your woods or cabintry classes. Students would use these while making projects to cut down the material to the correct lengths. Table saws today are very safe to use. Especially the Saw Stop table saw. It is replacing most older saws in schools across the country. It minimizes the risk of student injury by allowing the blade to stop in milliseconds. Future use of Table Saws in Teaching- I do not see the use of table saws changing much in the future. Other than i believe it will become more common to see schools have these and have students using them in the classroom. As far as safety in the future. Saws today are about as safe as they are going to get i believe. Being able to stop the blade in millisenconds is the number one concern since that is what injures the students when usign this tool.

Microscope

History of microscopes in teaching: Microscopes were first introduced in classrooms in the mid to late 1900’s. They were used to teach students the makeup of cells, the reproduction of cells, and to look at what kinds of organisms are in just one single drop of water. Current use of microscopes in teaching: Microscopes in the classroom are being used for the same reasons as they were when they were first introduced in the classroom. They are used to show students what cell division looks like, what blood cells look like when they are over saturated or undersaturated, or even to look at hair follicles. Future use of microscopes in teaching: We don't see the use of microscopes changing too much when being used in the classroom. They are going to be used to show students cells, and what cells look like.

History of telescopes in teaching: Like the microscope, the telescope was introduced into classrooms in the mid to late 1900’s. They were used to teach the students about the history of the telescope, as well as the parts that make it work and why it works (optics). Also, they helped introduce astronomy to students as they could now make astronomical observations about what they saw using the telescope. Current use of telescopes in teaching: Telescopes are being used in many of the same ways in classrooms today. There has been more of an emphasis on teaching why and how the telescope works the way it does. This whole concept is called optics. In our own experiences, there hasn’t been much of an emphasis on teaching astronomy in the high school/ middle school level outside of the bare minimum of learning the solar system. Future use of telescopes in teaching: We don’t see the use of the telescope changing much in the classroom. Teachers will still use this tool to teach and explain optics. There could, however, be a change in emphasis into what is taught with the telescope, similar to how optics are the main principle being taught today as opposed to in the past when it was more oriented towards the general history of the telescope. Perhaps the future will see a rise in the teaching of astronomy to high school/ middle school students using the telescope.
