This week we started our journey into the microscopic world that surrounds us. We looked at compound microscopes and how they work. First we looked at a variety of prepared slides - honey bee wings, plants, single cell animals. Then we prepared our own slides to investigate the differences in bottled water and pond water. Lastly, we viewed a large variety of student provided materials under the microscopes.

Our two big questions this week were:

• Where did all of those little things come from?

• Why aren’t microorganisms in tap water?
