Analyze and Extend You will convert your revolutions per minute into approximate wind speed.

Part A
Remove the pushpin, and place the cups and straws on a table so you can find the circumference of the anemometer. Lay the string on top of the cups to make a circle that passes through the centers of the cups, as show in the image. Use the marker to mark the point where the ends meet or cut the string at the meeting point. Straighten out the string, and use a tape measure to measure the length of the string in inches. Write down the length.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
