Give the sequence of planning for your science classroom using inquiry approach in teaching concept of density. a. allow students to determine relationship between objects that float and sink. b. allow students to play with water in a tub with different objects. c. ask students to design a small boat that can carry 1 kg of weight.

Using the inquiry approach, learning starts with concrete exploration, moves to identifying patterns/relationships, and culminates in application. So first students play with water and objects (b) to observe phenomena, then they determine the relationship between floating and sinking (a), and finally they apply the concept by designing a boat that carries weight (c). The correct sequence is b → a → c.
