Tuesday 14th March
For a long time we have been planning our Lab-13 Lectures, and tomorrow is the day! We are going to present our lectures about Sound to about 400 children and teachers! Jamie says that he is scared, but James is just excited. We have planned our talks in partners: Elizabeth and Izzy about how sound is made by vibrations, James and Ellie about how sound travels in waves, Ty and Sam have some experiments about how we hear sound, and finally Jamie and Charlotte have some great facts and recordings about how bats and dolphins use ultrasound. We’re about to go and practice at Wollaston: it’s really exciting!
Wednesday 15th March
The day has arrived we are all scared and nervous but hopefully it will go well! We meet in the morning at school at 8:15am, so that we have plenty of time to get ready for the lectures.
When we got to Wollaston School we went to the hall that was very big with comfy seats. We had some spare time to practise, when we practised there was just one thing that we all were doing wrong: we were all talking too fast so we ALL NEEDED TO SLOW DOWN! We also got to practice with real volunteers for the first time: which was good because we discovered that volunteers are very bad at doing what you want!
During the actual show, it all went really well! The audience really enjoyed being part of a sound wave, and testing their own hearing. After we did all our own lectures, the fantastic Rick Hall presented a quiz where the audience had to decide if new inventions were real, or made up. Everyone in the audience got to vote by holding up wither a green (for fact) or red (for fiction) card. Finally Mr Sheldrick and Mr Bodycote (science teachers from Wollaston School) did some experiments. Not just any experiments though: They were trying to impress us to decide if chemistry or Physics was the best!
Afterwards we had some time to experiment with our new giant slinky, and Rick showed us some more experiments he had brought with him. We also caught a few passing teachers and showed them all of our experiments! The day went very well, and when we got back to school everyone was tired. Elizabeth would love to do the lectures again though: maybe we will do them for the rest of our school!
