                                        INVESTIGATING AIR RESISTANCE
        Truth to Teach (Source)

              God wants us to trust Him, in the same way as a parachutist trusts his parachute as he steps
              out of a plane.

        Learning for Life (Fulfilment)


              For the children to appreciate how God has enabled people to understand principles of air
              resistance and to discover a way of using air resistance to save lives.

              For the children to be encouraged to open up and to depend on God to hold them and to lead
              them. (Ephesians 5:18)

        Way to Work (Means)

              1.     Remind the children how air can move things, carrying them along in its flow, especially
                     on a windy day; how hot air can lift things in its flow too.
                     When we are moving with the Holy Spirit, and we are trusting Him to help us, it is a good
                     place to be.  It is ‘easy’.

              2.     Explain  that  today  the  class  is  going  to  investigate  things  falling  through  the  air  and
                     learn how God has helped people discover a way of using air to save lives.

              Experiment 1:  Dropping a flat piece of paper and a crumpled piece of paper from a
                              height and observing which lands first.


                       •  Predict what will happen.
                       •  Observe. Repeat the experiment.
                       •  Interpret results.  [Air got trapped under the sheet of paper and pushed
                       •  against it, so slowing it down.  Much less air got trapped under the ball of
                       •  paper, so it fell quicker.]
                       •  Does this piece of paper floating gently down through the air remind you of
                          anything?  Can you think of a situation, in which it would be good for something to
                          fall slowly through the air, rather than quickly?

              Experiment 2:  Dropping a peg (dolly-type) and a peg attached to a parachute from a
                                      height, observing which lands first.

                       •  Predict.
                      •  Conduct the experiment.  Repeat.
                      •  Discuss results.
                           [As the parachute fell it filled up with air and this trapped air slowed the peg man’s
                           fall.  He landed safely.]
                      •  Ask: could we make the peg-man come down even more slowly?
                           [Use a larger parachute.]
