Dunk and Flip
Learners complete two simple experiments to prove the existence of air and air pressure which surround us. First, they push an inverted cup into water; the air in the cup prevents water from entering. Then, they try to flip up a meter stick covered by paper; the air above the paper pushes down and prevents the stick from moving easily. These can also be used as demonstrations. When learners set up a free account at Kinetic City, they can answer bonus questions at the end of the activity as a quick assessment. As a larger assessment, learners can complete the Smart Attack game after they've completed several activities.
