Students comprehend and describe that light waves, sound waves, and other waves move at different speeds in different materials. They are divided into pairs and given a beaker and straw. Students are instructed to fill their beakers three-fourths full of water. Pupils are asked: "If you insert your straw into the water and then look at it, what do you expect to observe?"

Students explore how light waves passing through a medium can be used to determine the sizes of particles within the medium. They assess exactly what "backscatter" and "forward scattering" is and their relationship to the reflection of light. In addition, they identify the substances classified by their physical and chemical properties. Full Review »

Students think about whether light is matter or energy before they participate in demonstrations and experiments to determine how spheres, light, and waves travel. They study that the current theory is that light is comprised of photons which sometimes behave like waves and sometimes like particles. They review the meaning of transparent, opaque, and translucent while singing a song.. Full Review »
