Materials Needed
Step-by-Step Instructions
- 1
Gather all your materials and choose a clear jar or glass for the experiment.
- 2
Start by pouring approximately 1/4 cup of corn syrup into the bottom of the jar.
- 3
Next, slowly pour 1/4 cup of dish soap on top of the corn syrup, allowing it to settle.
- 4
Then, carefully add 1/4 cup of water, pouring it slowly to avoid mixing the layers.
- 5
If desired, add a few drops of food coloring to the water layer for a fun effect.
- 6
After the water layer, gently pour 1/4 cup of cooking oil on top of the water.
- 7
Observe how the layers stay separate and discuss why this happens with your child.
- 8
For added fun, drop small items like beads or marbles into the jar to see where they sink or float.
- 9
Discuss the concept of density and why some objects float while others sink.
- 10
Encourage your child to experiment with different liquids or quantities to see how it affects the layers.
- 11
Record observations and draw conclusions about density and buoyancy.
- 12
Display the density jar as a colorful science decoration.
