Pendulum Play

                             
                             We built a pendulum using PVC pipes.
 
          We learned to set up blocks and other items to knock down. 
          
We learned how to pull the pendulum back and let it go, or sometimes run with
                                       it through the blocks.
                   
                              Then we set up more blocks
                           
                                  and even more blocks
                         
                            Then we knocked them down again.
