Emphasis is placed on heat, light, and sound.
Experiments and demonstrations guide students to an understanding of basic concepts, such as reflection and absorption. Practical application of these concepts and relevance to everyday situations are stressed. Have students experiment with a ripple tank to observe reflection and refraction and then draw the wave patterns. Stretch or have a student stretch a Slinky across the floor. Flick one end sideways to demonstrate that energy can be transferred from one point to another by waves.
