        Week 5

        Truth to Teach (Source)

                      To introduce the concept that the keeping quality of food can be improved by
                      processing it and storing it properly.


        You need:
                       A few tinned foods, and food in jars and packets.

        Way to Work (Means)

                  1.          Have the display of food before the children.
                              Read  from  Exodus  16:13  –  35.    Recall  the  time  God  rained  down  bread  from
                       heaven and the people had to go and gather it.  How often did they have to gather it?
                       Why?  (It would go off, except on the sixth day!)  Today we are going to look at how
                       we store food, so that it doesn’t go off so easily.

                            2.     Here is a tin of peas. Could I have bought peas in something other
                       than a tin? [Frozen peas, or pea pods.]
                              Why are peas put in a tin or a packet for the freezer?
                                Establish that:

                                         •  it keeps the food clean and free of germs
                                         •  it makes the food stay fresh longer

                                         •  it makes it easy to handle small foods like peas.

               2.             Food can go off because of microbes. These are invisible, and are like
                              germs. They multiply in food if they can and make the food go off causing it to
                       become unsafe to eat.
                              However, God has helped people discover ways of treating food and   storing it
                       so that it can stay fresh much longer.

                                         •  Canning: in this process the food is heated up, in a sealed tin, and
                                         this  destroys  any  microbes  in  it.  The  tin  keeps  any  other  microbes
                                         out.
                                         •  Freezing: blasts of very cold air are directed at the food, and this
                                         stops  any  microbes from multiplying. You must then keep the food
                                         frozen by storing it in a freezer.
                                         •  Storing  in  a fridge: this slows down  the  multiplication  of  the
                                         microbes.  Food will stay fresh longer in a freezer   than in a fridge.

               3.  How might you know if food had gone off? Draw the three warning triangles on the board.
