In this PowerPoint, I discussed the axolotl and why and how it is endangered. I talked about how the construction industry is destroying axolotl habitats and forcing them to move, also pollution of the earth is causing Axolotls to move because of the rising PH levels in the water. The reason there are multiple of the same slide in the PowerPoint is because when I am presenting it could throw me off when I need to scroll and this might mess me up during my presentation. The reason I chose the axolotl is because I thought that it looked nice and with it being added to Minecraft, it gained lots of popularity in recent years. I could improve my work habits by being more efficient and finishing my work faster with fewer distractions. Still, other than that I think that I did this assignment to my full ability and I put lots of effort into it.

Owl Pellet Dissection

What surprised you during the dissection?

One thing that surprised me is how many animals could fit in that pellet, there where many skulls and lots of bones in the pellet when we dissected it.

What challenges did you face while articulating the skeleton?

Some challenges that I faced while trying to articulate the skeleton was finding all the bones and aligning the ribs. Lots of bones were missing and we had trouble finding where they went in the skeleton. Also the ribs were very small and hard to align.

What did you learn about owl diets and ecosystems?

An owl is at the top of its food chain, it eats many different types of rodents, such as mice, rats, shrew, moles, vole, etc. They cannot digest bones or fur so they turn all the bones and fur into pellets that they spit out. Also owls live in almost every climate, such as deserts, tundra’s or prairies.

How did this activity connect to what we’ve learned in class.

This activity connects to what we learned in class in many ways. It relates to biology because we are studying how animals work and what their organs do. First, we learned about the rat and its organ systems. Then, we dissected a frog to look at its internal organs. Finally, we examined an owl pellet and saw the skeleton of a rat, which helped us understand the skeletal structure. Through these activities, we explored different layers of animal biology: the external body (through diagrams and lessons), the internal organs (through dissection), and the skeleton (through the owl pellet). This shows how the owl pellet dissection tied into everything we learned in class.

This is our assembled skeleton:
