Sink or Float

Young children enjoy learning about how things work.

By participating in a vast array of science activities, they are learning important critical thinking and observation skills.

These activities also promote their inherent sense of curiosity about the world.

For this activity we experimented with sinking and floating.

Using real pumpkins, we placed them in water to observe whether they would sink or float.

Ghosts in a Jar – Density Experiment

A primary vehicle to scientific instruction is that of example.

Because the study of scientific concepts incorporate both observation and experimentation, our classroom activities strive to both display and apply this type of instruction.

jar1

Your budding chemist learned that all things are made up of molecules.

We talked about how some molecules are bound really close together while some molecules are bound further apart, and the word that describes this phenomena is known as “Density”.

jar2

Using three different materials (all the color white to go with our ghost theme), we placed each into a bowl of water and observed how each material dissolved.

We then discussed why we thought some materials “disappeared” faster than others.
