Secret Lab 2: Sound

Professor Knowitall explores sound with Dr Spark and Dr Bright

Factual series explaining all the mysteries of the world of science in BSL! In this episode, Professor Knowitall and his sidekicks Dr Spark and Dr Bright explain how sound works. How do submarines navigate underwater? Dr Bright gets sent into a submarine to find out! There he learns about sonar and how it helps to make sense of objects in the sea. Later, Dr Knowitall shows how sound causes vibrations, which is how music is created. We also look at how sound energy can pass through liquid and gases. Finally, Dr Bright visits some caves to find out about echoes!Aimed at children of Key Stage 3 level. Don’t miss it!

  • HI i am a GCSE Science assistant at the Royal School For The Deaf in Derby and find The Secret Lab fantastic .They are entertaining and easy on the eye for retaining the topic you are signing about.I think the only thing that worries me is the use of so much fingering spelling throughout your varoius topics.Working with deaf secondary children they would find that hard and doing so may miss out on vital scientific concepts or termology. For example you fingerspelt oil and gravity in one of your videos and i have a sign for that.I have two reference books linked with Science vocabulary that i use for our children within teaching Physics,Chemistry and Biology and i find that the children retain the information better that particular way.Also the children like to think that a hearing member of staff has gone away and researched the correct BSL sign for the topic being taught.For signs that have no language equivalent,so i have created a nounce sign to cover the subject thats being taught.If i can be of any help at all regarding any language or science concepts please dont hesitate to email me.Continue the good work and we could do with loads more science videos to help people who are out there struggling to teach and learn about science.Many thanks.Sarah Hall :)
