Students actually produce the possible precursors of life-coacervates. The liquid, colloidal suspension produced by students will exhibit some of the same properties of living organisms. When the membrane-like structures surrounding the droplets are ...

Students will simulate a gene pool using different colored pop beads to represent alleles for a genetic trait in a population. Comparisons will then be made between the resulting frequency of alleles in the population with and without selection press...

An effective classroom simulation of the classic peppered moth natural selection study. Students assume the role of predatory birds capturing moths on a simulated bark background. Results show students firsthand how the moths’ population directly rel...

Prior to Louis Pasteur there was a commonly held belief that living microbes could arise from non-living matter by a “mysterious” process known as spontaneous generation. Pasteur was ingenious in designing “controls” into experiments and his classic ...
