Junior biologists journey through the hiearchy of living things with these activites. Using a dichotomous key, they identify common algae, plants, and fish. They design their own key for a mixture of seeds and a collection of miscellaneous objects. Black and white dichotomous keys are provided for the first few activities, but if you can provide colored versions, it would bring more life to the identification exercises. Also, with four keying and two designing lessons, it could be redundant. Maybe choose one of each.
