Adaptations of Steam Organisms

Jessica Rodriguez
1) For the organism you investigated, what are 5 facts you learned and found interesting?

1. The crayfish eggs stay under the mother's tail (swimmerets) until the eggs become independent juveniles
2. The crayfish was one of the main animals used in discovering plate tectonics because they are located on many continents
3. The female's eggs are not fertilized until they hatch.
4. Crayfish are very tolerant to pollution
5. The time that juveniles depart from their mother's tail depends on temperature, dissolved oxygen, predators, population, and food supply.

2) Choose three other organisms; for each, list two facts that you learned during the presentation.

1. Flat Worm- The flat worm is expected to live for ten years and it can reproduce asexually or sexually.
2. Crane Fly- The crane fly is eaten by birds, bats, and yellow jackets, and it's the bug that looks like a mosquito on steroids.
3. Stone Fly- The stone fly does "pushups" to move oxygen through its gills and is eaten by the crayfish.

3)What did you enjoy about this project?





My favorite part of the project was presentation day, because each group did so well presenting. I was so intrigued by the facts they displayed, and it was awesome how so many groups made their normally bland macroinvertibrate facts colorful and interesting. Also, I got to practice speaking in front of a group of people, and it's always good to get as much practice with that as possible.





4)What was the most challenging aspect of this project? Do you feel you successfully overcame this challenge? If not, how would you overcome this challenge in the future?

My biggest challenge personally was finding time to work on the project, and finding time to come up with a plan with my group. It was hard to balance out working with collaboration during class, and outside of class it's difficult to collaborate. I believe our group overcame this obstacle, because our presentation went smoothly and we were all comfortable with how we did and the work we got done.
