# 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.

# Scuba Diving

This activity provided several opportunities for increasing our vocabulary!

We not only learned about what pressure and compressed gas are, but applied our understanding of these words by “swimming” beneath the ocean waves.

Scuba diving is not only a fun recreational sport, but a science that integrates physics, chemistry, physiology, and oceanography.

As they placed their heads below the water’s surface, your budding divers learned about differences in air density.

As they examined an array of creatures in their inspection jars, they applied their knowledge of measurement and observation.

Lastly, as we explored the differences in the habitats our ocean friends enjoy, we learned that all creatures live and feed at different depths, so creating an ocean floor of many levels aided our understanding of this multi-dimensional concept.

# Sea Urchin Math

We are always striving to improve our counting and math skills! Using colored pasta, toothpicks, and Playdoh, we created our very own sea urchins.

We began the lesson with a revisit to the number six. We then practiced tracing the number six with our fingers. Following that, we wrote the number eight. Lastly, we counted as we placed each piece of pasta onto each spiny plate.

Experiences that allow the application of mathematical principles are an integral factor in the development of mathematical concepts.

This activity also fostered their sequencing skills, as many of our budding mathematicians found more pleasure in arranging their pasta pieces by color.
