Weigh the mineral Dip the mineral in acid Heat the mineral until it melts Drag an edge of the mineral across a tile
I gave my students this multiple choice question: Which action should be taken in order to identify the streak of a mineral during an investigation?

Only one answer is correct among these 4 choices:
- Weigh the mineral
- Dip the mineral in acid
- Heat the mineral until it melts
- Drag an edge of the mineral across a tile

Could you tell me which one is correct?

Drag an edge of the mineral across a tile
