Just before our winter break, the third grade class completed a unit on how things work. They investigated what might make a machine do what it does.
At the end of their unit, they invited the whole school to watch as different groups of students made their wonderful contraptions come to life.
Citizen Scientists
Take a look at the video to see what the students made – in action!
This activity was inspired by Rube Goldberg machines. To take it a step further, the third graders used this as inspiration for several centering lessons on chain reactions in their emotional and social lives.
When the kids were working collaboratively, they had to use these things to receive full credit:
At least three simple machines
- At least five exchanges of force
- Examples of friction
- Examples of gravity
- And, of course, teamwork.
This presentation of their machines was the culmination of the entire unit. Students did several experiments based on the scientific method that helped them build upon their prior knowledge for this activity.
It’s pretty amazing how just a little rolling ball can have such a powerful impact on integrated systems.
Of course, this unit blends in so well with our theme of systems thinking this year.
