Lesson Components Time Inquiry Skills Tech. Used Engage Level Brief Description
Engage 10 min 5.2 Projector, Computer, and Video 2 Students are given a video to watch pertaining to the speeds of sound and EM waves.
Explore 20 min 2.6, 3.1, 3.2, 3.5, 4.2, 4.4, 5.8 none 3 Students work in small and large groups to simulate how the speeds of sound and EM waves change through solids, liquids, gasses, and a vacuum.
Explain 30 min 4.3, 5.3, 5.4, 5.7, 5.9, 7.2, 7.3 none 3 Students will graph and analyze their data. They will construct an explanation about how the speed of sound and EM waves change as particles get closer together and farther apart.
Expand 15 min 3.3, 5.3, 5.4 none 3 Students will analyze data of an unknown type of wave, classify it as either a light or sound wave, and support their claim.
Evaluate 10 min 7.2 none 1 Students will take an exit ticket addressing the learning targets.
