Problem: - Electromagnet creates magnetic field with electricity - Conductive copper wire is wrapped around a piece of metal - An electric current gets introduced from power source - Flows through the wire - Magnetic field gets created in the wire - And the metal gets magnetized What might be the last step of the process?

A: When turned off it is no longer magnetic.

Problem: - Plants and animals long ago died - They are buried under layers of soil - Pressure builds over time - The remains liquefy What might be the last step of the process?

A: The carbon atoms rearrange to become a new substance.

Problem: - There is a lot of rain or a dam breaks - Water levels of a river or lake get higher - Water builds up on the ground - Water covers streets - Water gets deep in some places - Water goes into houses and other buildings - The rain stops or the dam is repaired - Water flows into streams What might be the last step of the process?

A: The rest of the floodwater evaporates.

Problem: - Chloroplasts in the leaf of the plant traps light from the sun - The roots absorb water and minerals from the soil - This combination of water and minerals flows from the stem into the leaf - Carbon dioxide enters the leaf - Light, water and minerals, and the carbon dioxide all mix together - This mixture forms sugar (glucose) which is what the plant eats What might be the last step of the process?

A:
Oxygen goes out of the leaf through the stomata
