Sense and Respond

In this unit, students will build models to understand how light enters the human eye and is processed. Students will compare this to light-sensing robots. 

Hands-on Activities:

• Students assemble a pinhole camera and consider how the movement on light in a straight line produced the image 
• A demo using a bowl with a hole in the center and string to model how light moves into the eye 
• Students assemble a periscope and model how light moves in a straight line to produce the image seen 
• Students explore robotic Cubelets to compare how robots and humans sense and respond to the world 
• Students use a ruler to test their reaction time given a variety of stimuli
