Objective(s) / Students will be able to learn about adaptation of retina based on external stimuli e.g. low condition light.
Students will be able to record the data and calculate accuracy
Students will be able to predict changes.
Materials and Websites / Stop watch and various color plastic bottle caps.

Smart Start / Provide students with a diagram of camera and have them match parts of camera to analogous parts of eyes.

Mini-Lesson / The retina contains two types of receptor cells.
(1)Cones, adapted for vision in bright light, allow us to perceive color.
(2)Rods, adapted for vision in dim light
The brain combines and interprets nerve impulses received from these cells; enable us to see in various light conditions.
Application (Group Work) / 1. Work with a partner. Using a stopwatch, time how long it takes to separate 30 plastic bottle caps into groups based on color.
2. Record the time, the number of caps in each group, and percent accuracy of the grouping.
3. Predict changes in the data if experiment is repeated in dim light.
4. Mix the caps into one group. Dim the light .repeat step 1
5. Restore light conditions and record the data.
6. Discuss the data with your group. Predict changes in the data if the experiment is repeated after five minutes in dim light
Analyze Graph the time required and the percent accuracy in each trial. How do these variables compare across trials?
Conclusion / Based on data, compare the action of blink reflex to the action of eye in adjusting to low light condition.
