Earthworm dissection
The earthworm is an example of a foraging herbivorous annelid, obtaining food by eating its way through the soil and extracting nutrients from the soil as it passes through the digestive tract. In this lab, students explored the simple digestive, circulatory and respiratory systems of the invertebrate (earthworm). |

Frog dissection Students look at the anatomy of the frog and see how it is more complex than the earthworm. For the first time, students see how the digestive, circulatory and respiratory systems look inside an organism and observe the organs associated with each of them. |
Pig Dissection
The dissection of the fetal pig in the laboratory is very crucial because pigs and humans have the same level of metabolism and have similar organs and systems. In this lab, students opened the abdominal and thoracic cavity of the fetal pig and identify structures.

Mimicking Bacterial Growth
Students work with water to mimic the growth of bacteria. Each drop represents thousands of bacterial cells and within each hour the bacterial population would double. After many hours students observe that quite a bit of water had filled in the beaker. The exponential growth seen here is what allows these micro-organisms to be so resilient and abundant in our bodies, ecosystems and the world. The study of bacterial growth also sheds light on how modern medicine develops medications and treatments for various bacterial infections.
