1. Take the cup of the seven different objects then pour the water into the funnel into the beaker.
2. In the cup separate the objects that can be separated into groups such as the toothpicks, the pebbles, the clear rock, and the sand.
3. Then you plug in the hot plate and put the beaker on the top of it; let the water sit there till all of the water has evaporated.

6. Be careful, take the tongs to remove the beaker away from the hot plate.
7. Do not forget to unplug the hot plate when finished removing the beaker.
