Adaptations of Stream Organisms

I discovered many things that I didn't know about the clubtail dragonfly by doing this project. First, I learned that they have a long, straw-like tail to help them breathe. They go through an incomplete metamorphosis, with only three stages. They usually stay fairly close to their breeding sites as they mature into the adult stage. The female dragonflies can lay up to 5,000 eggs. Lastly, their lifespan can be anywhere from six months to two years.

Dobsonfly

  • Stays underwater for most of its life
  • Has a lifespan of only three to ten days 
Mayfly

  • Goes through an incomplete life cycle composed of three stages
  • Live in rough, running waters because they require a high amount of dissolved oxygen

  • Damselfly
    • Metabolism changes based on environment
    • Have claws to help them stay on the rocks in the water
    I really enjoyed working with a group on this project! I feel that working with others and talking about what we have discovered allows me to learn and obtain information much more efficiently than working alone. The visual aspects of the project made it a lot more fun as well.

    It was challenging to decide what kind of visual aid we were going to use, because there are so many choices and pros and cons to each of them. When we decided on creating a prezi, it was frustrating at times when the computer wasn't working correctly. However, we asked for help and by using Mrs. Bates' computer, we overcame our difficulties. 

    Overall, I enjoyed working on this project and hope we can do more group activities like this in the future!
