Electricity Lab: Circuit Challenge

This activity is a series of 10 circuits. The students are to build circuit one and move through each circuit challenge. Each circuit gets progessivly more difficult. This activity uses both series and parallel circuits.

From Classical Taxonomy to Phylogeny

Students reasearch the taxonomic breakdown of a variety of organisms. Students will look at was characterisitcs are present and absent. Through this investigation they will determine the plausible evolutionary history of the organism.
