Three Phases of the Investigation

Based on our experiences with scientists and students, we find that there are three general phases of exploring an image. As detailed below, these phases help students:

1) get started wondering about an image

2) get oriented to the features, scale and viewing angle of the image

3) use the images as the focal point for extended investigations.

In the discussion which follows, we interweave a sample investigation into the discussion of the three phases.

As your students pursue their investigations, it will be helpful for them to have a notebook to record their progress. The investigation may end up following a "wandering line of inquiry" as one question leads to another. The notebook will help them keep track of their questions, conjectures and insights in this process.

Provide your students with plastic overlays and fine-line markers. Placing the overlays over the images enables your students to label features in the image, note areas of interest, mark and trace patterns, etc. A magnifying lens can also be very helpful.
