Different Forces and an example of each
Gravity-Falling to the ground
Buoyant-Floating up to the surface of a pool
Magnetism-A magnet sticking to a fridge
Applied-Pushing a cart
Tension-Playing tug-o-war
Drag-A parachute slowing you down while skydiving
Friction-Snow passing under a toboggan
Spring-Bouncing on a trampoline
So far, students in 5M have devised a method to generate a consistent wind speed by flapping a piece of cardboard from a specific height and at timed intervals. I was very impressed that they figured out how to make a consistent wind force without having to be taught how to do it.
Next, the students were challenged to design a structure made of playing card that could withstand the force of the wind generated by their flapping piece of cardboard. Surprisingly, the structures withstood quite a bit of wind force, many not falling down at all.
Here is a video demonstrating a low wind force and the card structure withstanding it:
