This assignment has two parts. The first part (A) requires that you have reviewed the course notes for this week. The second part (B) requires you to watch some videos and respond to prompts about them. Part A You will first need to review the course notes for this week and watch the recorded lectures. Please post at least two well thought out questions that you have over this weeks material. Questions should be based on the course notes or lectures and be related to physical science. These questions can include things you are not sure you understand, concepts you find confusing, or questions that go beyond the scope of this course. I will respond to one or both of your questions in the grade comments section after submission. Part B Below you will find links to online videos for you to watch followed by a few prompts. Choose one or more of the prompts to respond to. Each prompt might include several questions, but you do not need to answer each one. Use these questions inside each prompt to guide and inspire your response. Your response for Part B must be a minimum of 150 words. You can choose to either watch one video and post a response of 150 words on that single video or you may watch more than one video and distribute the 150 words across more prompts. For example, if you chose to watch two videos, your response could be 75 words each for a total of 150 words. Why Earth’s Magnetic Shield Matters
Prompt #1: What happened to the once living planet Mars that forever made life impossible there?

Discuss some of the conditions and characteristics of Earth that make it just right for life to survive and flourish here. The Coolest Things Sound Can Do
