Answer:
It involves experimentation and observation of the pencil dropping from different heights
Step-by-step explanation:
Students are being asked to drop the pencil from different heights and to measure the time it takes for a pencil to fall from different heights and then calculate the speed corresponding to each height and measured time. In this scenario the students are doing science as they carrying out experiments and making observations to find a unknown which is the speed of the pencil falling from different heights.
