Aim: To look at a twat flea and a h iodineybee downstairs a microscope and draw what is seen. Materials: Compound microscope, microscope map hand out, brisk mistakes of cat flea and honeybee. Prediction: I predict that it bequeath be relatively simple to set up the microscope and see the flea and honeybee, but non easy to draw the flea and honeybee picture. Procedure: 1. bring in microscope from trolley. 2. Set up microscope and switch on the microscope light. 3. Collect cat flea sloping trough and charge under microscope electron lens, view at mass medium power. 4. Sketch flea in pencil (1/2 or just page size) and commemorate cat flea from the overhead sheet. 5. furnish flea slide and collect honeybee head slide, place under microscope lens and view at low power. 6.

Return honeybee slide and pack up and return mic roscope. Observations: I found that the microscope was set up quite an easily and I had runty trouble figuring out what to do, thanks to the diagram sheet. I first drew a couple of robustious drafts of the flea before doing my trustworthy copy. I do not speak up that it is a genuinely good drawing, but it was the best that I could do. The honeybee was a little bit harder to draw, because I could not see all of it clearly at once, but I did get it drawn. Conclusion: I think that this experiment was a very good federal agency to show how to view things with a microscope. Questions: 1. You do not contain a microscope to view a flea, incisively to view one up close. 2. There is only one way merchandise in the lab to prevent collisions which could molest the equipment. 3.

When you put the flea upside down under the microscope, it appears to be veneering the right way. 6. The honeybee was harder then the flea to focus because the slide is thicker on the honeybee. 7. a) The high power lens has the least profoundness of subject because it is zoomed in more. b) The honeybee required more attainment of sector because it is bigger that the cat flea. 8. On both slides, in that discover are little hairs all over the specimen, which you hind endnot see with the innate eye. On the honeybee, you can see all of the different spark of the mouth, as well as its compound eyes. On the flea you can see the legs and you can also see the eggs. 9. The flea does not go wings, but it makes up for th at with its powerful jumping legs. 10. The flea is flat because it allows it to run very quickly through the cats fur and it cannot be caught.
