In this lesson plan students learn about the property of light: refraction. The lesson begins with an engage demo placing a pencil in a glass of water. The students will be able to witness the effects of refraction. After answering a few questions the students are split into partners for the explore portion of the lesson. The students place a penny on the bottom of an opaque cup then step back until they cannot see the penny. The partner then slowly pours water into the cup until the penny comes into site (record data). The teacher leads the class in a classroom discussion about their findings. The teacher then explains what refraction is and why it happens. For the elaborate portion of the lesson students are asked to explain how to spearfish from a riverbank. There is a short quiz for the summative assessment.
