In a science class, Mr. Sumit brought some materials: a water bottle, a glass, and a thick paper sheet. He poured water into the glass and put the thick paper sheet over it. Slowly and carefully, he inverted the glass and removed his hand from the paper. Learners were surprised to see that the paper stuck to the glass and water did not leak out. Some students said that the paper had glue on it, while others said it stuck due to the water inside. What was the pedagogical objective of performing this task? (A) Help learners understand that experiments are a principal route to scientific knowledge. (B) Encourage learners to construct explanations based on their observations. (C) Encourage learners to ask questions.
