In reviewing the online microscope lab homework, we discussed several important points. When you looked into the microscope you saw a backwards, upside down "e" with a red ring on it. When you zoom in, you would see less of the of the backwards, upside down "e" with a red ring on it. When you try to move the slide away, the slide moves towards you and when you try move the slide towards you, it moves away from you . When trying to move the slide to the right, it goes to the left, and when trying to move the slide to the left, it goes right. Also, remember when looking at a specimen object through a microscope, always start on the lowest objective power first, then you may increase the power. Also, there are four objectives on our online microscope; 4, 10, 40, and 100.
^^The online microscope we used.^^ After we went over the important microscope things and the homework for the normal microscope users, we viewed three pieces of thread under under a microscope connected to the SmartBoard. We were able to see what you would see through the oculars of a microscope, on the SmartBoard screen.Matt demonstrated how to move the slide and adjust the coarse adjustments on a microscope. We saw that the string that we thought was a single string, was actually composed of twisted string. We proved that you can focus on different layers of a specimen, however you cannot look through.
If you were absent and need to view the online microscope lab again, this URL will there. http://www.udel.edu/biology/ketcham/microscope/scope.html
