Description

Understand that the combination of bicarbonate and vinegar produces a chemical reaction, a gas called carbon dioxide.

Scientific concept introduced

Volcano, crater, eruption, lava, food colouring, bicarbonate, carbon dioxide.

Creative and critical thinking

Critical thinking:
– Analysis
– Observation
– Reflection

Creative thinking:
– Curiosity
– Amazement

Mathematical reasoning

Comparison of quantities

Scientific thinking

– Formulating hypotheses while watching the experiment
– Reproducing the experiment
– Evaluating the results
– Applying the results of the experiment to everyday life

Learning how to learn

– Ask yourself whether the same reaction can also take place with other ingredients and create various combinations, explain why this is not the case

Additional

– Actively participating in the teacher’s execution of the experiment
– Predicting possible results
– Becoming familiar with the ingredients
– Choosing the most suitable tools
– Concluding the activity with tidying up

Teaching methodologies/activity outline

Introduction:
Show the children/young people the material they will need to carry out the experiment and say to them: “What do you think we will do with this material today?”

“The eruption in a bottle” is the name of the experiment we are going to carry out today.

The experiment will be used to recognise changes in a substance

Activities:

After explaining the experiment to the pupils, the teacher gives them all the materials needed to carry out the experiment and guides them through the activity.

Material:
A plastic bottle.
Adhesive tape.
Scissors.
A green envelope.
A plastic container to raise the “mountain” and to contain the liquid that will escape.
A funnel.
Vinegar.
Bicarbonate.
Red food colouring.

Instructions:
– Cover the bottle with a green envelope so that it takes on the appearance of a volcano.

– Then, using a pair of scissors, pierce the envelope to free the top of the bottle and secure everything with adhesive tape.

– Using a funnel, fill the bottle halfway with vinegar.

– Pour in the red food colouring and mix the ingredients

– Add two teaspoons of bicarbonate to the inside of the ‘crater’.

Conclusions:

This activity aims to make the most of chemical reactions that occur with certain elements that are easy to find in the home.
The ultimate goal is to arouse the children’s interest, but also to initiate them into the study of chemistry and the elements found in nature.
