Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Students conduct experiments and collect data to determine physical and chemical characteristics of acids and bases.

Students work with models of substrates and of enzymes and test the digestion of lactose with lactase. They determine if digestion of lactose has or has not occurred.

Learners define what a redox reaction is. In this chemistry lesson plan, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Hang a soda can from a string and watch it spin by the force created by water streaming out of slanted holes. This plan provides background information, detailed materials and procedures, discussion questions, a lab worksheet, and...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Learners describe a complex path by the use of adding vectors. They comprehend the difference betwee scalar and vector quanitities. Students disucss the naviagation lab. They are explained the procedures for the lab. Learners are...
