1. Students will learn how to use the Bird section of the Digital Atlas
2. Students will observe how bird beak adaptations are specific for the types of food they consume.
|Pipettes||Colored Water in Bottle|
|Strainer||Marshmallows floating in a bowl of water|
1. Have your students to use the bird section Digital Atlas of Idaho. Click on Atlas Home, Biology, Birds, then on Birds of Idaho Checklist.
2. Let students examine the beaks of the following birds by scrolling down and clicking on the common bird name. Judging by each bird's habitat and diet, what do you think each beak is adapted for? (class discussion)
3. Put out the bowl of floating marshmallows, rice, marbles, and bottle with colored water. Explain to the students that these four items represent different kinds of food for birds.
4. Show students the pliers, pipettes, tweezers, and the strainer. Tell the students that these items represent the beaks of different species of birds.
5. Ask students to predict which kind of "beak" will be best for getting which type of "food".
6. Ask for four volunteers, give each student a "beak" and see who can obtain the most rice in 30 seconds. Get four more volunteers and do the same with the colored water, marshmallows and marbles. Advise students that they can only use their assigned "beak" for obtaining food. No cheating!
7. Record data on the blackboard and analyze the data.
8. Ask students which "beak" worked best for which "food" and discuss how their answers are supported by the data.
9. Ask students to explain why the pipette was best for getting water out of the bottle, tweezers were best for the rice, pliers were best for marbles, and the strainer was best for the marshmallows in the water. Did their predictions turn out to be true?
10. Ask class for discussion why different kinds of birds have different types of beaks. Discuss the birds from the list or other birds they might be interested in and to make predictions about the diet of each species based on their careful observations of its beak (Different birds consume different types of food)
