This complete Introductory Dissection Lab Kit is a great way to introduce students to dissection! It has everything needed for dissecting a frog, earthworm, perch, and crayfish. It includes our dissection tool set, preserved frog, earthworm, perch, and crayfish specimens accompanied by dissection guides for each specimen, and four disposable dissection trays. This stand-alone lab kit can also be used with several homeschooling biology curriculums.
