The Hindenburg- Titanic of the Air

In 1937, in the skies over Lakehurst, US, New Jersey State, the German airship Hindenburg suddenly burst into flames. It had been filled with flammable hydrogen gas.
Static electricity was said to caused the airship tp explode into a ball of flame, which quickyly burned the airship. This was the end of the hydrogen airship industry. Airship today use helium, which is not flammeable and yet also lighter than air.

Guiding questions for students:
1. Why was hydrogen used?
2. Why was helium not used then?

Possible Extentions:
1. Get students to play reporters and report the Hinderburg incident; they can report 'live' or produce a newspaper report for the Newspaper.
2. Students can also come up with a short documentary on the lesson learnt from this incident.

Using History To Teach

History has been recommended to teach science. Personally, as a student, I enjoy reading the autobiographies and biographies of some scientists, especially the female ones as I find their lives fascinating and amazing. I like to immerse and transport myself back to those times and see how these scientists work in their homes, labs, against the scepia background. Vivid thoughts and imaginations you will say. But I like that. It is not so much about the discovery that I was very much into; but rather, their determinations, the way they lived, their dedications. Hence, I believe in the value of using history; for it can be a means to interest the students, especially those with interpersonal intelligence.
Of course there are other advantages of using history. For one, it enables students to see the development of a science concept or model over time and help students see that the nature of science is that it is not perfect, but one should seek to improve on the current knowledge.
Another is that history help orientate students to the process of science; of how an investigation was planned to study and obtain the results that help establish the knowledge that they are studying today. Also, it serves to help them understand that with new technology, more gaps to current knowledge can be filled and help them understand the ever changing state of flux and improvement that the field of science is in.
But due to time constraints and the tight curriculum schedule, the teacher should exercise professional judgement in using history. However, it does no harm for the teacher to read up on a few incidences and do some research on the pausible ideas that he/she may want to incorporate in some chapters...
