The custodians came to school this morning and
found several suspicious boxes in our classroom.
They were too scared to move the boxes, so they
need your help! They are unsure of the contents
of the boxes or where they came from. Your job
is to move the boxes to the marked spot. Since
we don’t know what’s in the boxes, you can not
touch the box when you’re moving it. Then we can
call the office to come collect the boxes.

pole. The poles are at opposite ends of
the magnet. The poles have the strongest

Get your engines started! Today you
are designing a ramp to show how fast a
race car will travel from the start line to
the finish line!
Gather your materials and begin to
build a ramp that will show the fastest
speed for your race car. You must try 3
different heights and time your car as it
travels from start to
finish!
