Unit Study Guidelines
1. Explain how waves transport energy.
2. Distinguish among transverse, compressional, and electromagnetic waves.
3. Describe the properties of waves.
4. Describe reflection, refraction, and diffraction of waves.
5. Describe how sound waves are produced.
6. Explain how sound waves travel through matter.
7. Describe the relationship between loudness and sound intensity.
8. Explain how humans hear sound.
9. Identify the properties of light waves.
10. Describe the electromagnetic spectrum.
11. Describe the types of electromagnetic waves that travel from the Sun to Earth.
12. Explain human vision and color perception.
State standards and benchmarks addressed by this unit:
| 7.2.6 | Read analog and digital meters on instruments used to make direct measurements of length, volume, weight, elapsed time, rates, or temperatures, and choose appropriate units. |
| 7.2.7 | Incorporate circle charts, bar and line graphs, diagrams, scatter plots*, and symbols into writing, such as lab or research reports, to serve as evidence for claims and/or conclusions. |
| 7.3.18 | Describe that light waves, sound waves, and other waves move at different speeds in different materials. |
| 7.3.19 | Explain that human eyes respond to a narrow range of wavelengths of the electromagnetic spectrum. |
| 7.3.20 | Describe that something can be "seen" when light waves emitted or reflected by it enter the eye just as something can be "heard" when sound waves from it enter the ear. |
| 7.5.1 | Demonstrate how a number line can be extended on the other side of zero to represent negative numbers and give examples of instances where this is useful. |
| 7.5.3 | Demonstrate how the scale chosen for a graph or drawing determines its interpretation. |
| 7.7.4 | Use symbolic equations to show how the quantity of something changes over time or in response to changes in other quantities. |
