Year 7 & 8 Science Experiments: Dissecting a Fish & a Heart 

Year 7 Science Experiment - Fish Dissection

Recently 7C dissected fish so they could examine the skeletal structures of a marine organisms.  Good fun and lots of learning was had by all.

Year 8 Science Experiment - Dissecting a Heart

On Friday, 8A Science finished the Biology unit by completing a heart dissection on a sheep’s heart. We learnt about the structure of the heart and the way it pumps blood throughout the body. It was great to put our theory into practice. We found out that a sheep’s heart has similarities to a human heart because when we cut into it, we found an aorta, left and right ventricles, and left and right atria. We also found that the muscle wall was much thicker in the left ventricle. It had taken us about two to three attempts to cut through the wall as it was so thick! The wall is thick due to its role to pump blood throughout the body. We put straws through the veins and arteries to see how the blood gets transported through the heart. Deoxygenated blood enters through the veins, and oxygenated blood leaves the arteries to be carried around the body. I really enjoyed the dissection and I look forward to more practical work in the science classroom.
