Hi, Sir. I appreciate your videos very much, they are extremely useful to teachers and students who want to perform lab activities but do not have enough resources to begin with. I see sir that you haven't uploaded a video since last year, which is a shame. Your videos deserve more views and comments. Again, thank you and Godspeed.
Hi Joanne This is Kate Gray replying - thank you for your comment. Brian had ideas to make many more videos but sadly he died in January 2014. You can go to www.scienceteachingalive.com to read more about Brian’s work AND to download pdf files with more info for each video. I'm delighted that you found the videos useful. Most of the videos were made while Brian was ill but he was keen to do as many as he could. We want these videos shared as widely as possible and to help teachers and students use these ideas in the classroom, so we are adding downloadable files for each video which will give more information to teachers on managing ‘active science learning’ in the classroom. There are currently downloads available for Acid-Base indicators, Electric Motor Effect, Electromagnetic Induction, Electrical Circuits. Sound and Pitch will be added shortly. We hope that with a good response to the videos, it will be possible to make more using ideas that Brian developed. Thanks again, and please tell your friends and colleagues!
I'm not sure how it works with rubber, but in longer strings the pitch decreases due to it needing more energy to vibrate, therefore decreasing the frequency, which in turn decreases the pitch.
murat kar Well basically the pitch depends on the amplitude. The smaller the amplitude due to the stretching out of the rubber causes a decrease in pitch since the two are directly proportional.
This was helpful. I used the container and elastic experiment to teach my students about pitch. Thank you!
Great sir best way of teaching god bless you sir

ScienceTeachingAlive I am so sorry to hear this. His work will continue to do good to all of us.
+ScienceTeachingAlive I'm so sorry to hear that he passed away but I'm glad that you are are continuing what he has started. All the best.
This is the first video i ever watched on ur channel and my heart sunk after reading this
Thank you wo much to share such things, The world need more of those personalities,
Thanks it's very helpful 🙏🙏🙏
Very good I like it
I just smacked my face with the rubber band trying to hold it on my teeth! 😂
simple materials, plenty of experimental fun! I will use the experiments in the kindergarten! thank you very much.
Gr8 video, appreciate that!
thank you very much. I am a new teacher and these videos help a lot.
Excellent
I love it sir I love to study and practical learning is the best way to learn faster. Please sir take out a video on electricity
I love your videos are helpful interesting and informative and I really enjoy and understand thank you
Wow nice sir,, please upload videos regularly thanq
great ideas! I am eager to use with my students. Thank you very much
v nice video sir
Thank u very much.I am going to do them with my students
when you stretch the rubber , what happened to pitch ? increase or decrease ??
I'm not sure how it works with rubber, but in longer strings the pitch decreases due to it needing more energy to vibrate, therefore decreasing the frequency, which in turn decreases the pitch.

Thanks
Helpful sir
Nice
Thank you sir
Thanks sir
I'm ten watching this
I am then too!
same
your teeth are sharp cutting that thing
A-Z movie
How to teach sound and pitch AND MAKE THE KIDS FALL ASLEEP.
Kids do not fall asleep when they are doing.
Liberis Puritatem they will not fall asleep if they will do it themselves with your guidance ofc!
thanks
