Simple Machines are tools used to make work easier. In science, work is defined as a force acting on an object to move it across a distance. Pushing, pulling, and lifting are common forms of work. A force is any push or pull that causes an object to change its position (movement), direction, or shape.
This week students explored new vocabulary connected to the unit (e.g. friction, force, pulleys, work etc.). We also discussed the concepts:
Form – what is it like?
Function – how does it work?
Students have formed groups to explore simple machines – they will research to become “experts” about one of the following – wheels/axles, pulleys, levers, wedges, inclined planes or screws.
They are using books and various websites to complete their research. Students will share their learning with the whole class and in the next few weeks they will use the scientific understandings gained to create their own inventions to move and lift objects.
