ZIPLINE SCIENCE
What force makes something move from a high place to a low place?
Gravity
What slows your zipline down as it slides?
Friction
What is Oobleck made of?
Cornstarch and Water
What is a prototype?
The first version of a design to test
What can you change if your zipline carrier tips over?
Make it balanced
What happens if you don’t tilt your zipline enough?
The carrier may not move
What happens if there's too much friction?
The carrier might stop or move slowly)
Is Oobleck a liquid or a solid?
It’s both – it’s non-Newtonian
What do engineers do before building something big?
Plan, build, test, and improve)
How can you slow your zipline down?
Add weight, more friction, or change the slope
Why does the zipline need a slope?
So gravity can pull the carrier down
What happens if there is not enough friction?
It may go too fast or fall
What happens to Oobleck when you press it hard?
It acts like a solid
What machine helps move people up a mountain by cable?
Gondola or cable car
What tool helped your team the most today?
Answers will vary
What do we call a ride that uses a cable to carry people?
Zipline or gondola)
How can we add friction to a design?
Use rough materials or drag
What real object acts like Oobleck for protection?
(Body armor or protective padding
What do engineers learn from testing?
What works and what needs to change
Why is it okay to test and fail in engineering?
