Lesson Introduction: The Wonder of Chemical Reactions

Objective

To engage students in the fascinating world of chemical reactions by sparking their curiosity and encouraging them to think critically about everyday phenomena.

Introduction Activity: "The Mystery Box"

Materials Needed

• A sealed box (or container) that holds a variety of everyday items (e.g. vinegar, baking soda, food colouring, balloons, etc.)
• Safety goggles for each student
• A whiteboard and markers

Step-by-Step Activity

1. Set the Scene
   Begin the lesson by dimming the lights and drawing students' attention to the "Mystery Box" placed at the front of the classroom. Explain that today, they will become "scientific detectives," uncovering the secrets of what happens inside this box.

2. Create Anticipation
   Ask the students to guess what might be happening inside the box. Encourage them to think about different substances and what reactions might take place. Write their predictions on the whiteboard.

   Example questions to prompt discussion:

   • What do you think is in the box?
   • Have you ever seen something fizzy or bubbling? What do you think caused that?
   • Why do you think some substances react and others don’t?

3. Safety First
   Hand out safety goggles, explaining the importance of safety in science experiments. Emphasise that scientists must always be prepared, even for the unexpected.

4. The Big Reveal
   Perform a quick demonstration using one of the items from the box (e.g., combining vinegar and baking soda). As the reaction occurs, encourage students to observe closely. Ask guiding questions:

   • What do you notice happening?
   • Do you see any changes in colour, gas production, or temperature?
   • What would you call this process? (reaction, change, etc.)

5. Discovery and Discussion
   After the demonstration, ignite a discussion about what they observed. Relate the reactions to their predictions and engage them in explaining the science behind what they just witnessed.

   This dialogue can lead into the core content of the lesson about chemical reactions, specifically focusing on elements, compounds, reactants, and products.

Conclusion

By starting with the "Mystery Box," you create an interactive and engaging entry point into the lesson on chemical reactions within the Science curriculum. This approach not only piques students' interest but also lays a solid foundational understanding of key concepts, making them eager to learn more about the science behind everyday phenomena.
