Activity 1
Canvas practice quiz- go into canvas and open “canvas quiz 1” (it is located in the module)
Take the quiz.
Activity 2
Short video about how to use a microscope
Activity 3
Sketching nature- use petri dish to claim the range of the sketch
1. Fold a sheet of paper in half. This will make 2 boxes on the front and 2 boxes on the back.
2. use a petri dish (or mug if you are at home) to draw a circle at the top of each box (4 boxes total)
3. place a natural object in or under the petri dish and sketch only what fits inside the perimeter of the dish. This
will mimic the field of view in a microscope.
4. Draw a total of 4 objects to scale using the petri dish to delineate the area. Remember: sketch only what fits
within/under the dish
5. label the sketches
-Object name
-Magnification= 1x (no magnification)
-label parts as needed
6. list 5 qualitative observations for each (descriptive terms)
7. list 5 quantitative observations for each (numerical terms: measurements or counting)
DUE Monday October 5 at the beginning of class. (stamped only if complete and on time)
Homework: whatever you don’t finish from the sketching/observation activity, be sure to complete before class Monday.
