Topic 4: Staying Alive!
Unit Summary
In this topic they learn about LIFE!! - including themselves! As a living being, we have a body composed of a number of integrated systems all based on the cell. As long as these systems are functioning properly we are healthy but when things go wrong, disease results. There are an increasing number of technologies that scientists use to correct problems and this topic examines some of these as well as looking at some of ethical issues which might arise. Students also look in more detail at what cells are made of, as well as differences in cells in different organisms.
