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 week's 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.

Can We Touch Things?

This video discusses how atoms are unable to come in direct contact with other atoms. Since we are made of atoms, does this mean that we can actually never truly touch anything?

You Can't Touch Anything (Youtube video)

Prompt #1: We are just a bunch of molecules that hang out together but don't touch each other. Is this believable? If this is the case, what goes on in the body that allows us to "feel" when we touch something? How is this related to an object applying a force to another object?

Nuclear Bombs

Knowledge is power, and science is all about gaining knowledge. While we generally think of gaining knowledge as being a positive endeavor, there are also circumstances where the act of gaining knowledge can bring negative results.

Prompt #2: Based on the different forms of energy you have learned about in your Week 1 and 2 Course Notes, what are examples of different forms of energy generated during an atomic bomb detonation? Is the technology used to produced atomic bombs also used in a peaceful manner? If so, what do you think could be the danger of it? How should we handle the residual materials?

Richard Feynman Explains Fire

This video reveals what fire is and even the true origin of trees. These are two things about which most people have misconceptions.

Prompt #3: According to this video, what kind of energy do plants use to synthesize its cells? What happens to this energy once the cells are synthesized? Is this energy stored in any shape or form? If so, how could we use it?
