Lesson�4:�The�Wheelbarrow�

Teacher’s Notes

The wheelbarrow, although a lever

in action, is a different type of lever

from that found in the balance and

seesaw. In those simple machines

the fulcrum is between the effort and

load. Talk about how both types of

levers share the same features – a

rigid beam that rotates about a

fulcrum, effort and load.

See the ‘A Quick Guide to Levers’ for

additional information.

relative positions of the effort, fulcrum and load, into 1st,

2nd and 3rd Class levers.

The seesaw and balance are examples

of 1st Class levers in which the fulcrum

is between the effort and load. In 2nd

Class levers the load is between the

fulcrum and effort.

See the ‘A Quick Guide to Levers’ for

additional information.

If time is available, or in a prior ICT

lesson, children could use the Internet

to research different uses of 2nd Class

levers. For example: a door, stapler,

bottle opener and nutcrackers.
