Using the Microscope to View & Sketch a Specimen Using the Microscope to View & Sketch a Specimen Students practice applying their understanding of the compound light microscope to draw a prepared specimen. Students are then asked to use a compound light microscope to create a wet-mount of a letter "e", position letter correctly on the stage of the microscope, students are asked to draw the letter, and determine the total magnification. Students were also asked to create other wet-mount slides of items they gathered from the field outside.

Microscope Lab Activity Students apply their knowledge and understanding of using the compound light microscope to draw a specimens to scale
	exceeds 4 pts	meets 3 pts	partially meets 2 pts	does not meet 1 pts
Letter and Specimen	4 All correct: Lowercase letter shown and well drawn cells/specimen. Student has placed great effort in their work	3 Lowercase/thick letter shown and/or a distorted representation of the specimens are drawn. not all information is included	2 Lowercase/line/ letter shown and/or a slightly distorted representation of the specimens are drawn. messy and unclear. missing information	1 missing letter and/or specimen
Accurate Drawing/Sketch	4 Microscope view represents the true/exact picture of the specimen in the "Field of View" title is present	3 Microscope view present or both present but are drawings are sketched quickly. not a lot of attention to detail title is present	2 Naked eye drawing present only. difficult to see what the drawing is supposed to represent no title	1 Naked eye drawing present only (copied from someone else) no title
participation	4 able to demonstrate how to prepare a slide completed 100% of tasks	3 did not demonstrate how to prepare a slide completed 100% of tasks	2 no demonstration completed 80% of tasks but copied the rest from lab partner	1 no demonstration copied more than 25% from partner.
Power of Magnification	4 Total magnification is used shown in the correct formula format. ex. 10X multiplied by 4X = 40X total magnification	3 Only the total magnification is present on all or most of the pictures.	2 Objective lens power on 2 or 3 pictures	1 objective lens power only or missing magnification on 4 or more
