Here is an interesting video for you to practise your listening comprehension skills while you learn some everyday physics.
Roger Bowley is a retired professor from the University of Nottingham (UK). In this video he explains how to unlock a car from various distances, using waves from his key, brain and a big bottle of water.
Methodology:
- Before watching the video, think about the topic and imagine the kind of vocabulary you will be hearing
- Since many words in physics come from Latin, they are very similar to the Spanish ones so you will have no problem in understanding them. Here is a list of words you will hear; how many of them do you understand? Do not look them up, just read them aloud. Use a pronunciation tool, if you need it
- central locking device
- press a button
- to flash (the lights flash)
- electromagnetic waves
- frequency
- MHz= megahertz
- wavelength
- range
- signal
- extend (extend the range)
- pace
- water molecule
- electric field
- proton
- upwards and downwards
- oscillate
- ray
- synchronization
- phase
3. Watch the video and listen for those words; once you hear them in context, you will understand their meaning. You may watch the video once for general understanding and the second time for listening comprehension: write the list of words on your notebook and tick them when you hear them.
Put this experiment into practice next time your parents park your car in a large parking lot. Let me know if it works!
