This activity introduces students to pure and impure substances by mixing. They will learn how different materials interact and observe the formation of solutions, suspensions, or reactions.
By engaging in sensory experiences through mixing, learners activate embodied cognition — they physically explore scientific concepts. Observing changes in mixtures reinforces their understanding of matter and states of purity, aligning with Vygotsky's scaffolding theory as they discuss findings with peers.
1. Gather 3 clear cups of water. 2. In the first cup, add 1 tablespoon of salt and stir until dissolved. 3. In the second cup, add 1 tablespoon of flour and stir; observe the result. 4. In the third cup, add 1 tablespoon of vinegar to 1 tablespoon of baking soda and watch the reaction. 5. Record the outcomes: which mixtures dissolved, which separated, and which had a reaction? 6. Discuss your findings with your partner. What did you learn about mixtures?
