ODMS 3/8 & NFDMS 3/9

Please download this document, but do not print it. Then use the document to answer the questions on the Google form found here. If you cannot find the answer, please go find it. No resources is off limits.




ODMS 3/2 & NFDMS 3/3

PART 1
Follow the link and click through the animation

Newton's 3 laws

Once you have finished the animation, answer the questions below in an email to Mr. Collings.
1. In your own words, what is Newton's first law?
2. Give one example of Newton's first law that you might see in everyday life.
3. How does this law affect the safety features found in cars today?
4. In your own words, what is Newton's second law?
5. Give one example of Newton's second law that you might see in everyday life.
6. How does this law affect where the big guys play on a football field?
7. In your own words, what is Newton's third law?
8. Give one example of Newton's third law that you might see in everyday life.
9. How does this law affect how spaceships can navigate in space where there is nothing to push on when the rockets go off?

PART 2
The following questions should be added to the email from above. These are focusing on how objects act when only acted on by gravity. We are not interested in what happens when other forces are added.

"Dropping the ball"
The following questions are all related to dropping a pen/pencil from about shoulder high.
1. What happens when you drop the pen/pencil?
2. Does it drop at a constant speed, or is it accelerating?
3. Why does the pen/pencil fall when it is dropped?
4. Is there any way to make the pen/pencil fall faster when it is dropped? (If yes, how? If no, why?)
5. What forces are acting on the pen/pencil as it is dropped? (List more than one)

"What goes up, must come down"
The following questions are all related to tossing a pen/pencil up in the air 3-4 feet
6. When you throw a pen/pencil up in the air, what happens?
7. What makes it go up?
8. Why does it stop and come back down?
9. Once the pen/pencil goes up and then stops, how does its motion differ from "dropping the ball"?
10. Does gravity pull the pen/pencil down, or push it down? Why do you say that?


ODMS 2/10 & NFDMS 2/11

If you have headphones, get them out. If the video does not run smoothly, you may have to pair up and share a set of headphones (one partner will need to turn their computer off). Click on the link below and then click on the tab that says "Original Video". Then click on the "Science of the NFL" link. Watch the videos on Newton's first and second laws.

LINK

In an email, copy and paste the "textbook definition" of Newton's 1st and 2nd law. Then write a response to the videos that you just watched in light of these laws. You need to make your case for why what you saw in the videos was a representation of Newton's laws. Take your time and really think this one through; I'm going to be picky.




NFDMS 2/7 & ODMS 2/8

Please take detailed notes (at least a page) on the link below.
Vectors - An Introduction

Add a summary of the animation below to your notes.
Interactive tour of vectors and balanced forces

In an email, summarize the following things.
1. What are forces?
2. What are balanced forces?
3. What are unbalanced forces?
4. How can we tell if a force is balanced or unbalanced?
5. What happens when two forces of different magnitude and opposite direction act on an object?
6. What happens when two forces of the same magnitude and opposite direction act on an object?


Great PVT simulation



NFDMS 12/10

1. Follow the link below and learn about using the cardinal directions to find directions. Once the animation has loaded, click on "Look" in the lower right hand corner and then follow the directions.

2. Take this online quiz and print the results (thank you Mr. Anker). When you are finished, turn it into the 8th grade science box.



3. Use mapquest to get directions someplace at least two hours away from your house, but still in California. There must be at least 10 turns along your route. Then re-write the directions, adding the cardinal directions.

4. We are going to start learning about speed and velocity. Play the game below and take notes on each question that you answer.

5. Once you have a bit of an understanding of how speed an velocity work, play the game below. Make sure to keep your reliability rating up.

6. Write a 1 paragraph summary of how velocity and speed are related and how to calculate speed and velocity.

7. When you are ready, get the speed worksheet from Mr. Collings and complete it. When you are finished, turn it into the 8th grade science box.

7. When you are finished with 1-7, you may work on your research project for Ms. Fain, anything else you need to work on, or read your AR book.
