Field of View • Field of view: • Observable area seen through the microscope • How much of the area can you see while looking through the microscope
Pretend the microscope works like a camera… LOW power/barely zoomed in
Pretend the microscope works like a camera… MIDDLE power/zoomed in some
Pretend the microscope works like a camera… HIGH power/zoomed in a lot!
Low power 1 2
With a partner answer the following… • How did the field of view change when you zoomed in from low power to high power? • How did the field of view change when you zoomed out from high power to low power? • Can you see more of the image or less of the image as you zoom in? • What is the benefit to zooming in/magnifying an image?
Estimation • Estimate: To give an approximate value • We are going to ESTIMATE the size of things by comparing them to something we know! Let’s try it…
Now let’s estimate the size of something microscopic! Low power 1 2 24.5mm!
Now let’s estimate the size of something microscopic! Low power 1 2 3mm!
