This is the first lesson in a series of lessons on waves. It is an exploratory lesson where students observe, draw and think about how waves are shaped, how they move and what creates them. The teachers creates a model using a plastic bottles with colored water inside. The students then make their own models using the materials and procedures set up by the teacher. Students observe and record the waves and how they change. Students also observe how a hair dryer creates ripples on water that the teacher models for them. Students then gather together to discuss their observations. The teacher creates a collaboration board as a means of recording their ideas/explanations around the speed of the waves and evidence to support these ideas from their observations and investigation.
