Teacher's field guide

What Students Need to Do: Students identify epithelial, connective, muscle, and nervous tissue in microscope images. They compare how the cells are arranged and what lies between them.
What Mastery Looks Like: A student can identify all four tissues in unfamiliar images and point to visible evidence. They can explain why tightly packed epithelial cells differ from connective tissue cells separated by surrounding material.
Common Misconceptions: Students may call any tissue with long cells muscle, including nervous tissue with branching cells. They may also think all muscle tissue has stripes or mistake the material between connective tissue cells for empty space.
How to Assess It: Show four unlabeled tissue micrographs. Ask students to name each tissue, mark one visible clue in each image, and compare the cell spacing in epithelial and connective tissue.

Lesson moves

Place acetate over four printed micrographs and have students trace cell outlines, spaces between cells, and any visible fibers or branches.
Ask students: Which two tissue images could you confuse, and what two visible clues would help you tell them apart?
Play a slide sort: give pairs eight unlabeled tissue images and ask them to group the images and defend each choice.
Show a skin biopsy image and ask students to mark the epithelial surface and connective layer beneath it, then compare their cell spacing.
