Make a Dust Catcher

Complete instructions for conducting activities in this slide set, including materials needed, setup instructions, student sheets (in English and in Spanish), answer keys and extensions, can be found in The Science of Air Teacher’s Guide, which is available free-of-charge at http://www.bioedonline.org/lessons-and-more/teacher-guides/air/


Procedure
Session 1

1. Create a small cloud by shaking a cotton ball dipped in baking soda (or cornstarch or baby powder, or use a dusty eraser; see PDF Safety note). Shine a flashlight through the dust cloud. Ask, What are we seeing? Do you think this always is in air? How could we find out?

2. Show students the dust catcher that you have made and explain that they each will make a similar one to take home. They will place the dust catchers in areas of their homes they predict will have the most air pollution. After one or two weeks, they will bring the dust catchers back to school and examine them for particles.

3. Guide students as they construct their dust catchers, following steps described on the “Make a Dust Catcher” student sheet (steps 1-6 above)
