Engineering Challenge # 4 - Ramps

Your first challenge is to make a ramp out of cardboard.

Remember:  you may only use cardboard, glue, tape, scissors or cutters and string for these activities.  Any kind of cardboard that you can cut is fine.

Here are some internet pictures I found to give you an idea of what you can build.

As you can see, you can build a ramp in lots of different ways.  The basic idea is to have a flat surface that something can roll down (or up!) that sits at an angle.  You will need supports to hold the top part of the flat surface off the table or ground.  Can you see the triangles that makes?

Would the cheerios box in the 3rd picture make a good ramp?  Why or why not?

Make ramps with your siblings or friends - find something to roll down them (marbles, toy cars  - hey! use the ones you made from the lego challenge #1!)  Time how long it takes your item to reach the bottom of the ramp.

 How fast did it go?
Can you make it go faster?
How high can you make the top of the ramp before your object falls off?
