The Baker’s lab THEMATIC PATHWAYThe Baker’s lab – Chemical reactions in everyday elements



Goals:




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.




The magic focaccia – rising



Gas mixing – fermentation



Bread in a bag




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.




Greedy osmosis



Two weights, two measures – static electricity



Cake science – Chemical experiment








Assessment



InitialBuilding 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 assessmentA. 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:
