Biology Lab

Each lab has provided our 9th grade students with exciting investigations and their own new discoveries. We have recently explored human cells, plant cells, live tenebrio worms and the internal anatomy of earthworms. Who would think we could analyze the actual cells of the human muscle, human blood and human bone? In fact that is what we did! The students experimented and discovered what happens when a cell is diluted with water and also with liquids of high concentration. From this lab, there were students who became interested and asked what I thought about them entering the medical field! There is only one answer: “Certainly, you can do it!” The earthworm dissection allowed each student to: inspect the various parts of the worm which makes up the digestive tract and pumping organs; learn how a worm knows where to go when it does not have eyes; how it breathes when it has no lungs or gills; and what our soil would be like without worms. Indeed there were students who were looking for yet another opportunity to dissect an animal, and this time a larger one! We have that coming too! Stay tuned…
