Volume is the amount of space an object takes up.  The students had fun discovering the volume of a piece of clay.  They put 50 mL of water in a graduated cylinder.  They then added the clay to the water and measured the water level.  They had to decide the volume of the clay.  We discussed how they could find the volume by using the measurements.  We repeated the measurements with more than one shape of the same piece of clay.  It was interesting to discuss their findings.

Identifying Matter

Everything that takes up space, has mass, and can be seen, touched, or felt is matter.  Is air matter?  That was the question of the day.  The fourth graders had fun exploring with balloons and bubbles to answer the question.  We found evidence to support that air IS matter.  How else does a balloon get bigger? It was fun to watch the children make their own discoveries, especially when they had a chance to "play" with the bubbles!
