Octopus Ink

Children learn more by participating in their experiences than interacting with a piece of paper.


When an octopus feels threatened, it may squirt out a cloud of ink, intended to confuse any potential captors.

To recreate this scenario in the classroom, we used food coloring, eye droppers, water, and a plastic octopus to examine the effectiveness of this primitive defense.

This activity helped your little one formulate their own predictions about what might happen when ink is added to the water, and then compare and contrast their results as they completed the experiment.
