Ramps for Investigation

New ramps are placed in the construction corner.  

How can the children use them?

 Gabey places a car at the top of it.  "It goes down," he says.

 Peretz balances the ramp on a pile of blocks.

 Sara holds the ramp as she lets a car down.
Gabey places it on the shelf.
The children experiment at different heights, seeing the speed at which the cars slide down. 

Yakir uses both ramps side by side.  He notices it keeps the cars from falling off.
