One of the best things about taking a biology class is growing bacteria. All students love it! In this lab students will observe the effect that different antiseptics and disinfects have upon the growth of bacteria.
I use this lab in my Biology I classes, but it can easily be used for a middle school science class, or a more advanced Biology class.
1. To learn to grow bacteria on agar in a Petri dish.
2. To learn aseptic technique when working with bacteria.
3. To test the effectiveness of disinfectants and antiseptics upon the growth of bacteria.
