Floating Fish

This activity is ideal for elementary school students!

This activity is a great tool to use to explain water density to your student! Dry erase ink is designed to be "slippery," which makes it easy to wipe off of dry erase surfaces, and is also much less dense than water, which is the basis of this experiment!

Materials:

* Glass dish or shallow bowl

* Dry erase markers (do NOT use permanent markers, the experiment won't work!)

* Measuring cup

* Water

Directions: Use the dry erase marker to draw the outline of a fish on the bottom of the glass dish. Retrace your drawing to make sure all the lines are connected, and let it dry for a minute or two.

Fill the measuring cup with water and angle the pour spout just inside the edge of the dish and slowly add water until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it.

Tilt the dish slightly from side to side and watch your fish float!
