Introduction to Substances and Mixtures

Begin with a Captivating Experiment

Objective:

To engage students' curiosity and spark interest in the topic of substances and mixtures through an interactive experiment.

Materials Needed:

• Clear plastic cups
• Water
• Oil (e.g., vegetable oil)
• Food colouring
• Small objects (e.g., sand, salt, pebbles, and sugar)
• Stirring sticks
• Paper towels

The Experiment: "The Mystery of the Mysterious Mixture"

1. Set the Scene: Start the lesson by dimming the lights slightly to create an air of mystery and present a question to the class: "What happens when you mix different materials together? Can we discover the secrets of substances and mixtures?"

2. Demonstration:

   • Invite a few students to join you at the front.
   • Begin with the clear plastic cups filled halfway with water, and have a cup of oil and food colouring ready.
   • Ask students to predict what will happen if you pour the oil into the water.
     "Will they mix or will they separate? Why do you think that?"

3. Mix and Observe:

   • Pour the oil into the water and stir it gently.
   • As the oil sits on top of the water, discuss the observations.
     "What do you see here? Does this mixture combine, or can we see both liquids separately?"
   • Next, add a few drops of food colouring.
   • As the colour disperses, ask them to think about how the substances are interacting.

4. Group Activity:

   • Divide students into small groups and provide each group with a variety of small objects (sand, sugar, pebbles).
   • Allow them to mix these materials with water in their cups and observe what happens.
     "What do you notice about the different substances? Are they behaving the same? Let’s explore!"

Discussion:

After completing the experiment, gather the class together for a discussion. Facilitate a conversation around the following points:

• Define what substances and mixtures are.
• Explore examples from their everyday lives (e.g., salad dressing, air, chocolate milk).
• Highlight the differences between homogeneous and heterogeneous mixtures.

Conclusion:

Wrap up the lesson with a challenging question: "If you could create your perfect mixture using any substances, what would it be?"

Encourage students to get creative and think about combinations they might use in cooking, art, or nature. This engaging introduction sets the stage for a deeper understanding of substances and mixtures throughout the lesson!
