• Arrows help students locate important features
• Mounted in a clear plastic holder that protects it on both sides
• Set of 15 includes detailed lesson plan on the topic under study

Male and female gametes differ dramatically in their form and size. Challenge students to learn about these differences and speculate as to why these cells have these particular forms.

Introduce junior and senior high school students to the world of microscopy with inexpensive, unbreakable microslides. Microslides consist of a strip of film with eight photomicrographs, each reproduced exactly as you would see them through a professional microscope under ideal conditions. You can supply all your students with their own microslides. A detailed text folder is included. Viewers are available separately.
