Lab 1 -Title: Element Experiment                   Date, name  

Purpose:  to observe some of the different properties in two gases

Hypothesis:  The different properties of density and flammability will help distinguish (tell the difference between) the two gases.

Experiment:

     Procedure- fill two balloons, one with Helium (He) and the other with Hydrogen (H₂) .   Describe their buoyancy in air.  Light them on fire and describe the reaction.

Conclusion:
