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.
In this activity, students mix a given quantity of salt with a fixed volume of water. Mass and volume measurements are made before and after mixing to determine if these quantities change. Students... read more
Osmosis is the process by which the concentrations of two solutions, separated by a selectively permeable membrane, equalize by the movement of a solvent such as water. This demonstration shows that... read more
