Okay folks, we are still covering the information from last week's blog this week. We wrapped up with characteristics and properties and we are going to jump into wave behavior after completing our lab on wave speed. Hopefully, I will get a chance to update this post with a few videos, but in the meantime go ahead and look at the FOUR PREDICTABLE WAYS that waves behave:

Questions to Consider This Week:
1. What is the color of George Washington's white horse?
2. What do you suppose we can only see objects black at night?
3. What is the difference between colors of light and colors of pigment?
4. How does light react when it interacts with transparent, translucent, and opaque materials?
Making Waves Lab
PQ: How does a wave's speed relate to its frequency and wavelength?

| Students completing the first wave and tracing over it before they measure the length of a wave. |
Your task is to conduct three trials making and measuring waves to determine the relationship between wave speed, frequency, and wavelength. As a group, go through the pre-lab discussion. Collect your materials and begin working on the lab. Follow the directions exactly how they are provided. You will need to add a "speed" column to your data table. What happens the the wavelength and the frequency increases or decreases? Were any of your predictions correct?
