Our 4th year students are enjoying the fantastic simple machines 6th years boys did last week.
Their pulleys and levers can show us how effort or resistance work in these simple machines.
On this video you can see how a pivot works. Pivots are used as irrigation systems saving lots of water and with this system farmers don’t need to set pipes or tubes sending water. Thanks to the pivots water is saved because the water is sent to the correct place.
This is the traditional irrigation system farmes have been using for years. In the parks of the cities or gardens it’s whate we use.
Cites or gardens.
