In Science we learnt that hydrogen is extremely flammable and helium is not. Our teacher showed us some of this footage from YouTube and then did an experiment.
Our teacher showed us how to make hydrogen. Then we did the experiment of high pitch (like the sound a balloon makes) and low pitch (low like an explosion) experiments.
In our books we had to draw three columns and the headings were good, a question mark and bad. We had to write if helium was good, bad or unsure (question mark).
We really enjoyed the lesson!
