Homeostasis in Cells

In this lesson plan, students make use of their knowledge about homoestasis, osmosis, and types of solutions to design their own science investigation that will enable them to prove and answer: Why it is dangerous to drink dead sea water. Students have to prove their hypothesis to this phenomenon. The materials for this activity are naked egg (as a model of the cell), distilled water, Dead Sea water (31.5% salt concentration), digital scale, and timer (phone timer).
