Re-write this interpreting question so it is asking about the NZ's Biogeography:

How did it happen?

Then, write an answer for it.

How can we accurately measure temperature, mass, length and volume?

In Science we need to accurately measure things so that during experiments we can compare, record changes and make conclusions about what we observe.

For example, we could measure how the temperature of water changes as it is heated by a Bunsen burner flame. Or we could measure the mass of an ice cube as it melts. If we were changing the amount of water given to plants to see if it affected the height they grew we would need to accurately measure the different amounts of water added to the plants and the height that they grew.

All measurements need units. In Science there is only one standard unit for each measurement. For example length can be measured in millimetres, centimetres, metres, kilometres, etc. but the unit usually used is metres. Inches, feet and miles are not used in Science.

The units and how they are measured:
