What force makes something move from a high place to a low place?

Gravity

100

What slows your zipline down as it slides?

Friction 

100

What is Oobleck made of?

Cornstarch and Water

100

What is a prototype?

The first version of a design to test

100

What can you change if your zipline carrier tips over?

Make it balanced 

200

What happens if you don’t tilt your zipline enough?

The carrier may not move 

200

What happens if there's too much friction?

The carrier might stop or move slowly)

200

Is Oobleck a liquid or a solid?

It’s both – it’s non-Newtonian

200

What do engineers do before building something big?

  • Plan, build, test, and improve)


200

How can you slow your zipline down?

Add weight, more friction, or change the slope

300

Why does the zipline need a slope?

So gravity can pull the carrier down

300

What happens if there is not enough friction?

It may go too fast or fall

300

What happens to Oobleck when you press it hard?

It acts like a solid

300

What machine helps move people up a mountain by cable?

Gondola or cable car

300

What tool helped your team the most today?

Answers will vary

400

What do we call a ride that uses a cable to carry people?

Zipline or gondola)

400

How can we add friction to a design?

Use rough materials or drag

400

What real object acts like Oobleck for protection?

(Body armor or protective padding

400

What do engineers learn from testing?

What works and what needs to change

400

Why is it okay to test and fail in engineering?

Why is it okay to test and fail in engineering?
