Why is Honeycomb full of bubbles?

Overall aims

● to enable pupils to explore the chemical reaction involved in forming the bubbles in honeycomb
● to develop pupils’ skills in listening and following instructions
● to develop pupils’ cooking skills of stirring and pouring
● to develop pupils’ skills in observing and predicting
● to develop pupils’ skills in measuring
● to develop pupils’ skills in creative thinking

Vocabulary - keywords should be understood

Honeycomb, sugar, golden syrup, spatula, sweet, bubbles, gas, mixture, froth, stir

Expected learning outcomes (operational aims)

The child will be enabled to:
- follow instructions for making honeycomb
- explore how water, sugar, golden syrup and bicarbonate of soda react with one another
- practice measuring liquids in non-standard units
- practice the skill of stirring with a spatula
- make observations about how ingredients react and change
- respond creatively to the experiment

Teaching methodologies/activity outline

Introduction:

1. Ask pupils to work in groups. Give a piece of honeycomb to each group and
discuss.
Sample questions: What colour is it? Have you ever tasted food like this
before? If so, what did it taste like? (Eliciting a sweet taste). What do you
think it’s made of? What’s inside the honeycomb? (Eliciting that there are
bubbles). Why do you think there are bubbles?

2. Explain to pupils that the main ingredients in honeycomb are sugar, water and
golden syrup (hold these items up as you identify them). Inform pupils that
they’re going investigate why honeycomb is full of bubbles.

 

Activity:

(Ask pupils to work in 4 groups, with one adult per group.)

 

Materials: (per group)
- 25g of sugar
- ¼ Tablespoon of water
- ½ Tablespoon of golden syrup
- ¼ Teaspoon of bicarbonate of soda
- Spatula
- Teaspoon
- Tablespoon
- Poster paper

 

Instructions:

(Each group will need to be carefully supervised by an adult)
1. Prepare by lining a baking tray with foil.
2. Place the sugar into the saucepan.
3. Pour in the water and golden syrup.
4. Place on a low heat.
5. Stir the mixture well, until all of the sugar has dissolved.
6. Raise the heat a little so that the mixture begins to bubble.
7. Stir a little more, making sure there’s no sugar left on the bottom of the
saucepan.

8. Take the pan off the heat.
9. Now add the bicarbonate of soda and stir well.
10. Ask pupils what they observe – the mixture should froth up with lots of
bubbles.
11. Pour the mixture onto a small baking tray, or into a mould to cool. Now
you have made honeycomb! Ask pupils to explain in their own words why
they think the bubbles appeared.

Inform pupils of the following: This is because of gas (like the gas inside a
blown up balloon). When the bicarbonate of soda was heated, it caused a
reaction and released a gas (called carbon dioxide). This gas caused the
sugar and syrup mixture to froth up and bubble. Those bubbles then
became trapped in the mixture and they stayed there and ‘set’ as the
mixture cooled.

 

Conclusion:

Ask pupils in their groups, to make up a fun and creative story explaining why
there are bubbles in honeycomb. Then ask them to do record it as an audio
story.
- Begin by planning the audio story
- Record it
    - Talk through each part of the story
    - Add sound effects – using voice or props
- Share the audio story with the other groups in the class
