Space Exploration
Fourth graders observe an empty 14 oz. clear plastic cup and measure how much water the cup can hold when it is completely full. They work in groups to fill the plastic cup, but half of the groups receive a smaller vial and the other...
Curated OER
Physical Changes and States of Matter
Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Density of a Gas
Eighth graders investigate the mass, volume, and density of a gas by producing it in a chemical reaction. The entire Density of a Gas Lab and L section of the K W L chart be formatively assessed.
Curated OER
Float or Sink?
Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
