Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Students examine how a hot air balloon works. In this hot air balloon instructional activity, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when...

Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...

Students explore the different types of balloons.  In this materials instructional activity students can complete several experiments including building their own hot air balloons, making balloon animals and experimenting with...

A fascinating lesson on states of matter is here for your young scientists. Dry ice is used to challenge learners preconceived notions about how solids work. They discover all sorts of interesting facts about states of matter from...

Students investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.
