"Evolution in six assay lessons!"
Evolution in six assay lessons? Once again those lovable Wartskis have come up with a timely response to a number of complex concepts of creation (and we don't mean -ism).
Students have the (half) time of their lives radiodating pennies and walking an evolutionary time trail. They are exposed to evolution by finding and making fossils, and they explore variation using teddy bears, beans and graph paper.
Includes: flour, graph paper, kidney beans, diatomaceous earth, string, salt, shells, vinegar, plastic bags, droppers, microscope slides and covers, happy and sad bear pads, disk, instructions.
