Isotoper. Et grundbegreb, der forbinder mange observationer i kemi og fysik. Det hjælper med at forstå observationer gennem en model i stedet for blot at huske dem. Start med kerneideen og forbind den derefter med konkrete grundstoffer, målinger og forsøg.
Start from what you can observe, then connect it to the model scientists use.
Look for one measurable consequence: a colour change, a temperature change, a spectrum, a pressure, a mass or a time.
A model is useful because it explains and predicts. It is not a literal photograph of nature.
