Ever wonder how much bacteria is killed by boiling water? This is great science project that will help you answer this question!
Science Project Supplies
- Kids biological microscope (with 400x magnification required to view bacteria)
- Well depression slide
- Cover slip
- Container with a lid for storing the water (an old milk jug works well - just make sure you clean it out before gathering the water).

Next, fill a pot with your pond water and boil the water for a minimum of 30 minutes. Once the water has cooled, place a drop of your boiled water under the microscope. Have the bacteria disappeared? Would you feel safe drinking this water? What remains under the microscope after the water was boiled?
If you are presenting your science project to your class, show images or drawings of what was under the microscope both before and after you boiled the water. Explain what caused the water contents to change.
