JL conducted lessons on pressure for 3E Pure Physics. Students moved to different stations to carry out simple experiments and make observations. Two of the stations with inquiry-based worksheets:
1. pressure changes in a balloon being pumped.
2. forces acting on an inverted water-filled cup covered with a piece of transparency.
Students wrote down their ideas of the physical changes with the help of free-body diagrams. A subsequent lesson was devoted to discussion of common misconceptions.
