The Baker’s lab


The Baker’s lab – Chemical reactions in everyday elements


Enhance pupil’s ability to measure the temperature

Enhance the pupils’ knowledge about some chemical reactions occurring in everyday elements

Enable pupils to explore the concept of energy and heat

Enable pupils to explore the concept of negative and positive energy

Enhance the pupils’ knowledge about the process of rising

Enable pupils to explore the concept of weight and mass

Enable pupils to explore how different ingredients may affect the final result of a cake

Transversal goals:

To enhance pupils research attitude

To develop pupils’ skills in listening and following instructions

To develop pupils’ cooking skills

To enable pupils to investigate food changes

To develop pupils’ expressive language skills

To develop pupils’ ability to work in group

Intended Learning Outcomes

The child will be able to:

  • Participate in experiments under the teacher’s supervision
  • Recognize and explain changes in a substance
  • Understand the bake functioning
  • Learn to use the bake under the teacher’s supervision
  • Understand the phenomenon of leavening
  • Write down the chemical formula of a gas
  • Investigate how positive and negative charges interact with each other
  • Observe and discuss how pepper and salt are divided through electrostatic energy.

The structure of the learning pathway

Stage I

Measure the temperature, knead, understand the process of rising.

Stage II

Understand the osmosis and the statics energy processes behind the cooking ingredients; understand how different ingredients can affect the result of a cake.



Building a mind-map: (e.g., What do I know about? What I would like to learn about…?)

Activating the prior knowledge of children

Ongoing – described in every resource

Final assessment

A. Reflection with the mind map prepared at the beginning – What have we learned? What was the most intriguing? What else would we like to know about cooking?

B. Voting for the most interesting experiment (children can put the sticker under the photo presenting their favorite experiment).

C. Self-evaluation of one’s own learning process.

D. Teacher’s evaluation: see the scale below:

He/she can regonize the changes in substances 1 2 3 4
He/she can explain the changes in substances 1 2 3 4
He/She can use the bake (under supervision) 1 2 3 4
He/She can write down the chemical formula of gas 1 2 3 4
He/She can explain the chemical processes 1 2 3 4

1 – Not at all
4 – At all
