How is inquiry different from a worksheet?
In a worthwhile investigation, students ask what will be compared, collect or inspect relevant evidence, interpret a pattern and evaluate the strength of their conclusion. A virtual simulation should let pupils change a variable and observe consequences rather than simply reveal a prewritten answer.
What about small schools or limited equipment?
Use a shared projected investigation or printable record where appropriate, and check each lesson's material needs before teaching. A digital model can be useful, but it is not a replacement for all hands-on science or for the teacher's scientific explanation.
What does the teacher receive?
Lessons have teacher plans and resources such as slides, investigation records and exit questions. Class management and saved student work require approved free teacher access. See the school information page for privacy and classroom setup limitations.
