Do all solids float? and Can liquids float and sink?

The answer to both questions is...YES!

We didn't do this experiment but it shows how some liquids float while others sink!

We discovered that corn syrup was denser than water and oil.  It stayed at the bottom and the oil (which is less dense) stayed at the top of the jar!

Do all solids float? and Polygons

In groups today, students were asked to choose 10 solids in the classroom.  They then had to predict whether or not they would float or sink.  They took a bin and filled it with water.  After that, they took their solids and placed them in the water to see whether or not they would float.








We have been learning about polygons.  Polygons have at least 3 straight sides so a circle is NOT a polygon.
