Study skills · Revision strategy
Watching an animation is the start. Make the next move yourself.
Predict, change one thing, and explain the result before moving to a fresh question.
The short answer
A visual model is most useful when you can connect a change on screen with an explanation. Before moving a slider or revealing a step, predict what will happen. Afterwards, compare the result with your prediction and explain any difference.
Conceptual illustration. Colours distinguish parts of the model.
Where the confusion starts
A smooth animation can feel familiar without proving that you understand it. Treat the controls as a way to test an idea. Colours and sizes are model choices: check what each one represents rather than assuming every feature is physically to scale.
WORK IT THROUGH
Explore a percentage increase followed by an equal percentage decrease.
- Predict whether the result returns to the original amount.
- Change only the percentage and watch the starting base for each operation.
- Close the example. Solve a fresh case and explain why the two percentage changes use different bases.
CHECK YOUR UNDERSTANDING
After watching an electron-transfer animation, what could you explain without replaying it?
Make a prediction or write an answer before opening the explanation.
Reveal the explanation
State which particle moved, how the electron count changed, why a charge formed, and which particle count still identifies the element. Then test the explanation using another atom or ion.
SEE IT. CHANGE IT. EXPLAIN IT.
Take the next step in the lesson.
Use the visual explanation in the lesson, then choose Practice to test the idea with another question.
