Hello readers! Yesterday in science we did our first dissection!! It was so cool, it’s by far my favorite thing I’ve done in science thus far. We dissected a chicken wing. The goal was to see the musculoskeletal system in the chicken wing and how everything connected to help the chicken wing move. I thought it was amazing, I really enjoyed it. The tendons are surprisingly stretchy and squishy and kinda clear-ish, that was interesting to me.
Method
Here’s how we did the dissection:
- We laid down newspaper on the table.
- We put on gloves and safety glasses.
- We got scissors, tweezers and a ice cream container lid.
- We put the chicken wing on the ice cream lid on the newspaper so the table wouldn’t get chicken on it.
- The first thing we took off was the skin. We were just going to pull it off, but that proved to be a challenge because of how tight and rubbery it was. We ended up using the scissors to help us get it off.
- We seperated the muscles from the bone with the scissors, being careful not to mess up the tendons.
- The dissection was done and we examined the muscles and bones!
Results
We never did end up using the tweezers, but in hindsight it probably would have made removing the skin way easier. I’ll remember to do that next time! My favorite muscle was definitley the bicep. I’m pretty sure it was the largest muscle there and it was round and squishy. I was very eager the whole time to dissect so I wasn’t very careful, I need to remember to calm down a bit next time since I believe we’re doing a sheep’s heart.

Discussion
Muscles help bones move by contracting and relaxing, which pulls bones up and down (they can’t push!)
