When Earth first formed, there were particles everywhere moving like crazy. When things began to settle down, the denser particles sank, while the less dense particles stayed at the surface. I wonder what will happen if I pour these 3 different liquids into a new container.
- 4 Beakers or Clear Cups
- 10 mL Water
- 10 mL Oil
- 10 mL Honey
*Exact measurements can be substituted for equal parts water, oil, and honey
- Pour 10 mL water into one beaker, 10 mL oil into another beaker, and 10 mL honey into a third beaker.
- Place an empty beaker in front of you.
- Pour water into the beaker.
- Pour oil into beaker – observe what happens.
- Pour honey into beaker – observe what happens.
Questions & Further Research
- Can you list the liquids (water, oil, and honey) from least dense to most dense?
- Do you think the particles in the densest liquid are closer together, or further apart than the particles in the least dense liquid? Why?
