Move It

Move it explores a variety of ways to transport materials

 
Activity.... Do - Think - Learn
The move it exhibit shows how a number of simple machines work.
How many machines are there in the ‘move it’ exhibit?
Which machine will move the beads fastest and why?
Why was the Archimedes screw very important in farming in countries like Egypt?
  
The Science Bit
A machine is a device that uses energy to perform some activity. Humans are machines. There are 4 machines on this exhibit, Archimedes Screw, conveyor belt, bucket conveyor and chute. The Archimedes Screw and chute are examples of the inclined plane. The belt and bucket conveyor both use pulleys. Pulleys allow us to lift loads far greater than we would with just muscle power.
The Archimedes Screw consists of a screw inside a hollow pipe. The bottom of the screw picks up its loads as it is turned. The contents are then drawn up the tube to the top working against gravity.
 
QCA:
Unit 1E – Pushes and pulls
  • That there are many sorts of movement that can be described in many ways
  • To observe and describe different ways of moving
  • That pushing and pulling things can make objects start or stop moving
  • To identify similarities and differences between the movement of different objects
  • To make suggestions about how objects can be made to move and to find out whether they were right
  • That it is not only ourselves that make things move by pushing i.e. wind
  • To ask questions about what is causing movement
Unit 4E – Friction
  • That there is a force between an object and a surface which may prevent the object moving
  • Air resistance is a force that slows objects moving through air
  • That the force between two moving surfaces in contact is called friction
  • That friction can be useful
D&T
Unit 5C- Moving Toys
  • That a cam will change the rotatory motion into linear motion
  • That different shaped cams produce different movements
