MACHINES

MACHINE DISPLAY

Bring in a display of some simple machines for children to examine and guess at how they work.

  • Music Box
  • Jack-in-the-box
  • Flash light
  • Toaster
  • Clock
Set out some safe tools and let children experiment by taking the machines apart.
At circle time, discuss what they think made each item work.
 
ITEMS THAT MAKE MACHINES MOVE

Bring in a display of gears, wheels, springs, switches, etc. for your children to examine.
Ask your children, why some things do not work, even though they have wheels, or switches. 
Machines often need sources of power to make the gears move.
 
SOURCES OF POWER

Give examples of different machines and have children guess what type of power moves them.

  • Windmill - wind
  • Lamp - Electricity
  • Push or wind-up toy – Man power
  • Water mill – water
  • Flashlight – battery
  • Car – Gasoline
  • Candle Christmas toy that spins - Heat
Have children think of other machines and discuss what power they use.
Discuss things we still do by hand, that would be nice if a machine could do them.
   
JUNIOR INVENTORS

Set out art supplies, plus wires, gears, nuts and bolts, etc.
Let your children make a pretend machines.
Later, at circle time, have children explain their machine, what it does, how it helps people and what source of power it uses.
It is not important if the idea would really work, it is the process of exploring ideas that is important.  Congratulate each child on his/her work.
 
HOW MACHINES MAKE WORK EASIER

Discuss simple inventions that have made work easier.
Name a current machine and have children discuss what people did before this machine was invented.  Examples:
  • Refrigerator
  • Oven
  • Vacuum
  • Car
  • Furnace
  • Electric Light
 
EXTENDED ACTIVITIES

If interest last, you may want to get into a discussion how we need to conserve power.  

Turn off lights when not needed.
Take short showers.
Recycle glass, aluminum, paper.
