Waves have patterns of motion.
[CER] DISCUSSION QUESTION:
What do all waves have in common? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / Investigate
1. Modeling Waves - model the properties of waves using string or twizzler candy.
2. Making Waves - investigate how sound waves are similar to, and different from, other types of waves using slinkies. 3. Wave Properties Analysis - model factors that influence the properties of waves including frequency, wavelength, amplitude and speed. 4. Modeling waves - measure, model and analyze waves with different amplitudes, wavelengths and frequencies. 5. Electromagnetic Spectrum One Pager - create a one-pager to compare and contrast properties of electromagnetic waves. |

/ Iii / Level Up!
During this lesson you will learn more about the characteristic properties and behaviors of waves including:
- Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).
- Waves can add or cancel one another as they cross, depending on their relative phase (i.e., relative position of peaks and troughs of the waves), but they emerge unaffected by each other.
- Two different sounds can pass a location in different directions without getting mixed up.
- Earthquakes cause seismic waves, which are waves of motion in Earth’s crust.

Bella wanted to develop a model using a slinky to describe the relationship between wavelength and frequency to a friend. Draw and accurately describe what Bella would have to do to increase the wavelength of this wave followed by what she would have to do to increase the frequency of the wave. MASTER [+6 points]

/ V / Knowledge Check
Earth's surface is made up of huge puzzle pieces called tectonic plates. These plates are like gigantic rocks that float on the molten (melted) rock underneath, called magma. Now, sometimes these plates decide to move. When they do, they can either crash into each other, move apart, or slide past each other. Most of the time, they move so slowly that we can't even feel it. But sometimes, they move suddenly and cause big shakes called earthquakes.
When an earthquake happens under the ocean, it can cause the seafloor to move up or down. This movement creates a big wave in the ocean called a tsunami. It's like when you splash in the bathtub and the water goes everywhere, except on a much, much larger scale! This wave travels very quickly across the ocean, sometimes as fast as a jet airplane! As it gets closer to land, the water piles up and the wave can become really tall and powerful. When it reaches the shore, it creates a tsunami wave and crashes onto the land, causing lots of damage. |
