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.

Type: Lesson Plan

Students will review the main interactions of light followed by a short investigation to understand how matter gets its color.

Type: Lesson Plan

Light travels at an incredible fast speed and it allows us to see everything around us. It travels as a wave which interacts with different types of matter in a different way. This lesson is designed for 7^th grade students to investigate the different ways in which light waves interact with matter. The type of matter depends on which state the object is in - solid, liquid or gas.
Note: The lesson covers only part of the standard addressed.

Type: Lesson Plan

Students will discover that light waves and sound waves move at different speeds through different mediums through inquiry, observation and collaboration with peers.

Time needed to complete this lesson:
2 Block Periods
3 Regular Periods

Type: Lesson Plan

This lesson focuses on the standards that require students to understand:

• What is light and how does it travel?

Type: Lesson Plan

In this lesson students will investigate how the various surfaces have different albedo values. Students will analyze the difference between radiation, conduction, and convection, the three mechanisms by which heat is transferred through Earth's system. Students will engage in collecting data, graphing their measurements, and presenting their findings to the class.

In this Model-Eliciting Activity (MEA), students will analyze data to determine which type of wave in a lab setting is best suited to power a toy car. Then students will analyze a set of data using data from going outside and using electromagnetic waves from the sun.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx

Type: Lesson Plan

In this Model-Eliciting Activity (MEA), students will have to determine which type of panel to choose for a fictitious greenhouse - glass or plastic and how much light, heat and moisture is best to let in - determined by whether the material is opaque, translucent or transparent. Students exploring how light travels, how heat moves and how it all affects temperature will find this activity fun and exciting. This is a fun challenge but applicable also to the environmental demands we are currently facing.
