Lesson 13: Waves Unit Apply
Turn in your completed study guide
Lesson 14: Waves Unit - Review
Practice test (not included in overall science grade)
Lesson 15: Waves Unit Test
Use an example to explain how we see an object's color. Be sure to use these terms in your answer:
Transmission
Reflection
Absorption
Smartphones connect to the internet wirelessly. When you send a text from your phone, the phone must first convert the information in the text into radio waves. The phone then sends these radio waves wirelessly to a nearby receiver that is connected to the internet. Describe the analog/digital conversion that occurs when you send a text. Be sure to include the definitions of both terms.
Lesson 16: Waves Unit Reflection
Reflect on what you have learned throughout this unit on waves. What was the most interesting concept to you? How do you think waves play a role in your daily life? How do you plan to apply the knowledge you have gained about waves in the future?
