Tug-of-War

1) List all of the questions your group came up with based on this prompt "Tug of Wars and Physics"?
What is the function of the rope?
Where is force important for the winning team?
What causes friction in the rope?
How much force acts on the rope?
How can one person exert a lot of force?
How is the losing team losing?
How does the ground affect the force?
Is it possible to break the rope?

2) What is your one focus question?
How is tug-of-war different on grass or cement?

3) List your Hypothesis- what do you think & why
People can put less forces (friction) on grass than they could on cement making the over forces less.

4) Explore & Investigate- describe everything that you did to help you answer your focus question.
We went outside and tried tuf of war on different surfaces to see how it can affect the game.

5) Wet grass provides less friction than cement. Physics.

Free Falling


1) I chose this video because it was short and informational.

2) This video is better than others because it is short and has enough information to understand free falling.

3) If I were to make a video on free falling I would make it short with enough information to understand the concept of free falling.

Spaghetti Tower

1)
2)

3) 82cm was our towers final height.

4) Our current design is excellent, one thing I dislike about it would be the foundation. The foundation could have been more sturdy.

5) The biggest challenge we faced was constructing the middle part of the tower, we overcame that by working slowly and carefully.

6) If I had the opportunity to redesign our tower I would just make it better in general, by spending more money on more tape to make it more sturdy. Right now it's pretty minimalistic.

Self
1) I felt pretty good during this activity it was a challenge but nothing to hard.

2) Our design was pretty different to everyone else in the class. It was small while everyone else went big.

3) If I could choose a material to add to the mix I would add hot glue, even though that might make things too easy.

4) I shared building and buying responsibilities.
