The point of the web quest is to encourage you to read!
Objectives:
•Complete the Web Quest on time, following the directions for each slide.
•Write an essay comparing and contrasting Chondrichthyes (cartilaginous fishes) and Osteichthyes.
(This essay will be a test grade)
Instructions:
1.Create a new Google Slides presentation and title it "Osteichthyes Web Quest".
2.Add a title slide with your name.
3.Proceed to create the Web Quest slides, following the directions provided for each one.
4.Do not get behind. Complete all assignments on time.
5. All assignments are Due Friday Oct. 25th.
Task
Osteichthyes, commonly known as bony fish, represent the largest class of vertebrates on our planet. This diverse group of aquatic creatures vastly outnumbers the combined populations of dogs, cats, humans, lions, tigers, and bears.
• Unlike the Chondrichthyes (cartilaginous fish) whose endoskeletons are made entirely of cartilage, the Osteichthyes are distinguished by their bony skeletons. To better understand the key differences between bone and cartilage, you can refer to the purple chart titled "Differences Between Bone and Cartilage" on the next page.
•As we delve deeper into the world of vertebrates, the Osteichthyes class will be the focus of our next discussion. This comprehensive exploration will provide valuable insights into these remarkable bony fish's remarkable adaptations and evolutionary success.

Conclusion
The web quest on Osteichthyes, also known as bony fishes, aims to explore the purpose and benefits of this activity. Osteichthyes are a diverse group of fish characterized by their bony skeletons. The web quest allows students to investigate the anatomy, physiology, and ecological roles of these fascinating creatures. By completing the quest, learners will gain a deeper understanding of the adaptations and importance of bony fishes in aquatic ecosystems. The web-based format encourages independent research, critical thinking, and the synthesis of information from various online sources. This engaging activity promotes scientific literacy and fosters a appreciation for the natural world.
