Construction: On the large or tab side of the manila file folder, punch a number of holes randomly (Figure 4). It may be necessary to cover the folder with an opaque material to prevent seeing the shapes in the folder. Next, tape the folder leaving the tab end open creating an envelope (Figure 5). Create an insert by gluing differently colored, randomly shaped pieces of paper to the sheet of construction paper (Figure 6). The inserts need not be the same for all prepared folders. Insert the construction paper into the envelope with the colored pieces of paper facing the holes (Figure 7).

Hand each student, or group of students, a manila folder (with the insert inside) and an erasable or non-permanent pen. Inform students that the inserts have certain colored shapes glued to them. Students, without removing the inserts, are instructed to figure out those shapes and colors. The only available information to the students is what they see of the colored paper through the holes. Have students trace their proposed shapes on the overhead transparency.

Using transparencies and erasable pens allows you to re-use the folders in other or future classes. The activity aims to put students in a situation similar to the ones that scientists face when going about their work. When your students finish their proposed shapes, take the time to make explicit the similarities between what they are doing and what scientists usually do:

Faced with a natural phenomenon (the insert), scientists pose certain questions to which there usually are no readily available answers (What is the shape of the colored pieces of paper on the insert?) Just like your students, scientists would rather handle the phenomenon first hand, which in the present case would be to simply pull out the insert and see how it looks. This, however, is rarely possible.
