This Week In Science #8

Side View

Dorsal View

This week in science we did many things. We started to dissecting  animals  some of us dissected a cray fish others dissected a giant grass hopper. We had to draw the animals first , we drew the dorsal view which is how the animal looks from the top , we also drew the ventral view which is how the animal looks upside down. A proximal is something that is closer to the center of the animals body for example the place where the legs and the body connect. A distal view is the place in the animals body that is not close to the center for example the end of one of the legs of the cray-fish. We dissected the cray-fish starting from the posterior part of the cray-fish ( tail ) to the anterior part ( head). It was really nasty not because of the insides but because of the smell it was very hard to cut it open with out gagging. We look pictures and analyzed some very important feature of the cray-fish the its gills , which where really weird.

This week in science we learned a lot of things. We learned the parts of the cray-fish like the dorsal view, ventral view, proximal and the distal parts of the cray-fish . We also learned words for things like butt which is posterior and head which is anterior . It was really nasty because when we opened the cray-fish up it smelled really strong and it was hard not to get sick. One thing that was really interesting was the gills on the cray-fish .
