Laboratory: Micro Rockets
If you know how to employ the exothermic reaction between hydrogen gas and oxygen gas to make a miniature rocket, then this worksheet is a fabulous lab sheet for your chemistry charges. First, they observe a spark in pure oxygen and one in pure hydrogen, then write out the corresponding chemical equations. Critical-thinking questions are asked about the combination of gases. Chemists work collaboratively to record flight distances and then compare results with other groups.
