Your first experiment

1. Choose a component and read “About this component.”
2. Predict what will happen when you change an input.
3. Adjust a control. Compare the diagram, readings and graph.
4. Try the task and explain the result in your own words.
5. Save two readings in your notebook to compare them later.

Each experiment explains the assumptions of its teaching model. Camera, microphone and GPS activities use simulated inputs; they do not access your devices or location.
