Students witness various stages of mitosis through preparing onion root tip slides. With teacher guidance, they learn a great deal through the hands-on process of preparing the slides themselves.

Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

Young scholars identify minerals from its physical properties accomplished through observation and testing of the minerals involved. They divide into groups and perform the physical property tests listed on the Mineral Background sheet.

High schoolers develop an experiment to test a hypothesis. They use their knowledge of antigen-antibody specificity to develop a hypothesis. Students articulate that the antibody-antigen specificity is one part of the immune system. They...

Students simulate methods used to extend the effective life of an oil well by extracting less available oil. They identify techniques which can be used and evaluate their effectiveness. Pupils are introduced to rock size and temperature...
