Biology: the Study of Life and Globe Biology,(see bibliographic description above) are the texts that are used at the High School I teach at. The use of these two texts given in this unit is only suggestive and indicative of the feasibility of solving the problems that the unit addresses.
The titles of activities given in this unit are intended to be suggestive of what is possible rather than prescriptive. One would need to consult the texts cited for lists of materials. All of these activities can be done with readily available, inexpensive and easily acquired materials.
