The four "windows" below provide a mechanism for assessing the level of understanding which the student has achieved upon completing the activities and challenges.

The purpose of each window:

Recall: Demonstrate actual understanding of poster's concept and content

Relate: Show near transfer of understanding to similar object or related concept

Connect: Using concept or causal model, show transfer of understanding to an unrelated object

Create: Presentation of a novel learning task by student

Recall

What are possible contributing sources to drag on an airplane? Define the term "drag" in your own words.

Relate

Where do you think the effect of drag is most crucial, on a glider or a powered airplane? Explain your answer. Examine pictures of airplanes and note the shape of the wings. Make sketches of the wing shapes. Using what you know about drag, think of some reasons why different planes might have different types of wings.

Connect

Examine different types of parachutes and their uses. How might drag influence the different shapes of parachutes? Find pictures of fish of different shapes. How might their shapes affect the impact of drag while swimming? Which fish do you believe is the most drag resistant? Explain.

Create

Redesign a balsa wood airplane so that it is more drag resistant than the standard model. Create three different kite tails and determine which tail supplies the right amount of drag to give a kite steady flight.
