Welcome Back! Evidence Review

Labs Continued…Student Microscope pictures
We are continuing to look at the medulla and cortex of hairs using the microscope. Next week students will have a summative quiz on identification of hair using the microscope and the data they have collected.
Here is a photo shared by a student using her IPhone and shooting the photo down the eyepiece of the microscope. Pretty cool! (By the way, this is a brown hair!)
