Life has been extremely busy here and I apologize for the lapse in posting.
Continuing the weekly lesson plans for an elementary science unit focusing on Kingdom Animalia.
Lesson 6: Fish
Read about and find examples of different kinds of fish using a good resource of your choosing . Our favorite resource is Eyewitness Books: Fish.
There are two main types of fish:
Cartilaginous Fish (Class Chondrichthyes)
1) Skeleton of cartilage
2) Rough leathery skin
3) Stiff fins
4) Many species bear their young
5) Powerful jaws with numerous teeth
Bony Fish (Class Osteichthyes)
1) Bony skeleton
2) Scaly skin
3) Flexible and often foldable fins
4) Lay eggs
Both cartilaginous fish and bony fish
1) Live in water
2) Take oxygen through gills
3) Have a swim bladder for buoyancy
While discussing what makes a fish a fish, be sure to compare and contrast to other classes of animals they have already studied. Be sure to help student understand and define words they may not have seen before, such as cartilage, flexible, buoyancy, etc.
Younger students-- Draw a picture of a particular species of fish and use the biodiversity website to explore the animal's taxonomy.
Older students--Fill out an animal report form (this one from CurrClick is free and will work for this activity), making sure to include the characteristics that make this animal a fish. Use the bio-diversity websitehttp://animaldiversity.org to explore the animal's taxonomy.
Objectives: Student will be able to list major characteristics of fish and give examples of both cartilaginous and bony fish. Student will be able to define "cartilage", "swim bladder", and "buoyancy".
