Challenging a Claim
Testing a Hypothesis
Scientists are skeptics; we don’t believe what can't be proven. We demand empirical evidence; we design experiments to validate or disprove a claim; and we test repeatedly for ourselves!
Discovering the concept of mechanical advantage: gaining force through added distance.
In this example, we learn how adding two or more pulleys to our lifting machine decreases the effort needed (force), but increases the amount of rope needed (distance) to lift the load.
The Scientific Method:
"How does soap interact with water?"
Here we have designed an experiment to generate an observation which can lead to the creation of an hypothesis.
Learning about the properties of matter.
Here we are estimating and comparing the densities of various objects by carefully weighing them, observing if they sink or float, and measuring their water displacement.
Re-enacting Galileo and Newton's observations about falling objects and gravity.
Trading distance to gain force: Here we are learning about levers and fulcrums and how they help us make work easier.
