The main IBSE approaches employed in this subunit are interactive demonstration, guided discovery and guided inquiry. Inquiry based skills developed in this unit are amongst others:
- Asking and answering questions.
- Planning and conducting simple investigations.
- Performing experiments.
- Employing tools to gather data.
- Analysing results obtained with experiments.
- Communicating results with the use of graphs.
- Using data to construct reasonable explanations.
- Communicating investigations and explanations.
- Understanding that scientists use different kinds of investigations and tools to develop explanations using evidence and knowledge.
The activity 5 is an open inquiry; students have to prepare questions to ask during a visit to a hospital to be able to make a leaflet for patients having an ultrasound examination.
Some activities in this subunit make use of ICT tools:
- Data logging - measurements with a sound sensor
- On-line simulations
- Computer as source of information.
