PATHWAY BASED ON SCIENTIFIC CONCEPTS
Exploring – how osmosis works?
Goals:
- Discovering the concepts of osmosis and solution;
- Investigating the process of osmosis and its application in the kitchen;
- Developing the children’s research abilities by conducting experiments;
- Creating the education context to observe and explain the osmosis in different contexts;
- Strengthening the research attitude in children
Intended Learning Outcomes
The child will be able to:
- participate in experiments with teacher’s support;
- observe the chemical reaction of osmosis and explain the concept;
- undertake the critical reflection on his/ her own learning
The structure of the learning pathway
Stage I
Creating opportunities to discover and build the concept of osmosis:
Stage II
The use of osmosis in the kitchen – investigating different dimensions of chemical reaction.
Stage III
Playing and having fun with osmosis
Assessment
Initial – creating the mind-map – eliciting children’s prior knowledge about chemical processes in nature (What do you know – what kind of chemical processes can you identify? What else would you like to know?)
Ongoing – described in every resource
Final assessment
- Returning to the mind-map and reflecting on What have we learned? What was the most intriguing / surprising for you? What else would you like to know about osmosis?
- Voting for the most interesting/ exciting experiment (children can vote with stickers or may draw the most fascinating experiment)
- Self-evaluation of one’s own learning on the chart prepared by a teacher (children draw + / -/ ?)
The example of the self-evaluating chart:
- I can explain how osmosis works
- I can give the example of osmosis in the kitchen or in nature
- I can conduct experiment like a scientist
- I can be a cautious scientist – I know how to follow the rules of safety in the scientific lab
- I can observe and make notes (record the experiment)
- I can use the osmosis in the kitchen
- I can measure liquids in different ways
