Creative and critical thinking

Critical thinking
Observation
Formulation of hypotheses
Discussion-Creative thinking-Flexibility of thought

Elaboration

Mathematical reasoning

Measurement, Comparison

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

– Being able to list the ingredients needed to reproduce the experiment illustrated by the teacher
– Accepting the suggestions and doubts of one’s classmates
– Wondering whether the same reaction can also occur with other ingredients and creating the various combinations, explaining why this is not the case
– Identifying the value of this experiment in daily life

Additional

Exactly follow the steps of a procedure

Carry out scientific observations

Produce an original product

Overall aims

– developing pupils’ ability to listen and compare notes within the working group
– follow the teacher’s instructions
– working in a team respecting roles
– understand how magma, inside the magma chamber, rises to the mouth of the volcano
– find out what kind of reaction effervescent salts have with water and oil
– discover the different density of water and oil
– understand that oil is less dense than water

Vocabulary – keywords should be understood

magma, magma chamber, volcano, effervescent salts, density, food colouring, oil, water.

Expected learning outcomes (operational aims)

the child/student will be able to:
– conduct an experiment
– discovering the different density of water and oil
– discuss the experiment and draw conclusions
the child/student will have developed the ability to:
– follow the steps of a process exactly
– scientific observation
– compliance with the rules and directions given

STEM skills – to which the learning unit is related to

CORE STEM SKILLS

Doing the experiment
Observe and discover cause-effect relationships
Calculate measurements and times
Asking questions

ADDITIONAL SKILLS

Coordination

Understanding

Teaching methodologies/activity outline

Introduction:
By activating the five senses, the children will analyse the characteristics of each material and will be asked where the chosen materials can be found in everyday life.
Presentation of the experiment to be put into practice, named: “Lava bubbles”.

The experiment will be used to find out what kind of reaction effervescent salts have with water and oil.

Activities:
The teacher will explain the experiment to the pupils, hand over all the materials needed to carry out the experiment and guide them through the activity.

Material:
transparent glass jar
water
seed oil
red food colouring
effervescent tablets

Instructions:
Pour the water into the jar up to the middle
Pour the red food colouring into the water and stir.
Pouring the seed oil into the coloured water
Place the effervescent tablet inside the jar

Conclusions:

When the effervescent tablet comes into contact with coloured water and oil, it begins to ‘fizz’, emitting bubbles that rise to the top and then fall back down again. The bubbles rise and fall like lava in a volcano. At the end of the experiment the children discuss together what they have learnt.

Assessment of learning

Debriefing between pupils and teacher; observation by teacher

Equipment and materials to be used in learning unit (tools, ingredients etc)

– transparent glass jar
– water
– seed oil
– red food colouring
– effervescent tablets

Kind of setting

Science laboratory or classroom
