Life science learners measure and record traits of seeds, leaves, and their own hands and then graph the data to find a continous distribution curve. They compare and color diagrams of seven different animals' forelimbs (not included), note the adaptations, and relate them to the animals' habitats. Finally, they compare earlobes and construct a pedigree chart. These engaging and educational activities are thoroughly explained in a way that makes them easy to carry out with your biology class.
