The NTCA investigation loop

The controls are not the lesson. The thinking is.

Strong science simulations help learners connect an action to evidence, then explain what the model can and cannot show.

  1. 1
    Predict

    Say what you think will happen before the model reveals the result.

  2. 2
    Change

    Adjust one safe variable and watch the visible system respond.

  3. 3
    Record

    Save a measurement, observation, drawing or spoken explanation.

  4. 4
    Explain

    Use the evidence to describe the pattern and its limits.

Model honesty

Virtual results are evidence from a model.

They help learners see patterns, prepare for a practical activity and test ideas safely. They do not prove that an improvised real apparatus is safe.

For physical work

Use teacher-approved materials and adult supervision around electricity, heat, chemicals, glass, sharp tools or biological samples.
