This week students explored new vocabulary connected to the unit (e.g., friction, force, pulleys, work etc.).
We also discussed and consolidated our understanding of the concepts:
- form – what is it like?
- function – how does it work?
We looked at the definition of a simple machine – these 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. (from: www.vexrobotics.com)
Students are currently working in small groups/pairs groups to explore simple machines further. They will practice their research skills to become “experts” about one of the following: wheels/axles, pulleys, levers, wedges, inclined planes or screws. They are using books and various website 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.
Here are some photos from learning engagements this week:
