Dtse2007:Phylum Chordata

INSTRUCTIONAL GOAL
Students will become familiar with the different characteristics of the 3 orders of fish.
 * Note: Classification of orders as bony, cartilaginous, and jawless is a more simplistic way of teaching classification.

PERFORMANCE OBJECTIVE

 * Students will be able to distinguish between the 3 orders of fish.
 * Students will be able to explain how fish obtain oxygen.
 * Students will be able to give examples of fish adaptations.
 * Students will be able to recognize parts of a typical bony fish.

INSTRUCTIONAL PROCEDURES

 * 1) 	I will ask students to name the five chordate classes.
 * 2) 	I will ask students to number the chordate classes in order of evolution.
 * 3) 	We will go over them. I will tell students we are exploring the first class of chordates in evolution, fish.
 * 4) 	I will give a short explanation about each station.

Station 1: Identifying parts of the fish

Station 2: Oxygen by diffusion

Station 3: Classification of Fish

Station 4: Fish adaptations


 * 1) 	Closure: Write down three new things you learned about fish. Stand and tell.

EVALUATION PROCEDURES

 * 1) 	Station work to be handed in

MATERIALS AND AIDS

 * station worksheets
 * PowerPoint of diffusion slides
 * textbooks

TECHNOLOGY USAGE
PowerPoint for students to view at station 2:

Slide 1: Animation of a fish obtaining oxygen

Slide 2: Animation of oxygen molecules passing from the water to the blood of the fish
