Students work scientifically by using analytical techniques in a systematic way to identify mixed up samples of ocean water. The context of the lesson is a mix up in a lab which students have to use their skills to solve.
- Understand the wider context and learning outcomes
- Work systematically
- Demonstrate and reflect on learning
- Scenario (10 mins)
Use the slides to set the context and share the learning outcomes.
- Planning investigation card sort (10 mins)
Students sort the cards into an order that will allow them to identify their samples systematically.
- Practical work (30 mins)
Students use pH and the mass of salt residue to identify which oceans the different samples came from.
- Self-reflection (10 mins)
Students reflect on their learning by considering how they could work more systematically, using the slide as a stimulus.
