This week in Science # 9

This week in science we dissected a Perch. A Perch is a certain type of fish that lives in freshwater. Before we even got to dissect it we did some research on this fish and drew a picture of what the Perch looks like, then labels the parts we see. We also took pictures of the Perch and labeled them on preview. After we labeled everything we saw on the outside the next time we had science we were suppose to open it up a certain way and investigate the inside. The room was smelling very bad the smell caused many kid to actually not want to do the project.

I learned many things this week, and most of them were about my organism which was a Perch. I learned that the perch live in freshwater like pounds, lakes, streams, river. They eat smaller fishes, and sometimes shellfishes. I also learned a few things about my other groups organism the Skate. I leanred that it is in the sharks family, they also have a slow growth rate, they have gills, and live in salt water

Even though my organism looked very different from my other partners organism they did have some similaries. One of the similaries would be they both have gills and one of the difference would be the Perch lives in freshwater unlike the Skate that lives in saltwater

This Month in Science

 

This month in science we did the Zoology Project with our new groups. The first thing we did was decide was biome we wanted to gather data on  that perticular biome. The research lasted a while because we wanted to make sure we got as much info as we needed in order to make a nice presentation (like above) and make sure that all the information we put it to each slide wasnt just slide of information handed to you, but that all the information "flow" together. After we did that David and Jamie gave us a few pointers on how to make a slide and how it goes all together to make sense. After that my group and i decided to assign certain slides to a person. Meaning that the slide or slides you got you are in charge of putting all the infor that need to go there and making sure it is done correctly. Then when all the slides are done David this new thing called screen casting which really is you recording your voice as you go through slides. When you record your voice you need to explain each slide and what it identifies. This is why we created speaker notes. Speaker notes a are the notes on the side of your slide that only you can see and you use that as a guide to go throught you slides and record. At the end we just saw eachothers presentations and gave eachother comments. This was my favorite part i learnded many new things about different biomes by watching my peers videos.

This week in science #8

The picture on the left is the ventral view of the crawfish Yasmin and I dissected, and on the right is the dorsal view. The dorsal part was where my partner Yasmin the open to observe the inside or the crawfish. What I labeled on the picture was the abdomen. This feature is the most distal part of the crawfish. Distal is the back or spine of the body or in this case of the crawfish. The proximal part of the crawfish would be the eyes. Proximal means the closes part to the body. The eyes are located in the anterior part of the body, meaning on the head area. The abdomen is located in the posterior area, mean the abdomen is around where the tail is at. You can tell by the picture this is true. The environment of the crawfish is surrounded by fresh water they mostly live on the muddy bottom area of the body of streams or pounds.


while doing this project i was honestly very disgusted because of the crawfish's guts coming out of it. It wasn't pleasant. Other than the disgusting part i did actually learned something. I didnt know that the crawfish's liver is yellow, but after dissecting the crawfish I saw something yellow then i asked Jamie what it was and she told me its was the liver.
