Barton's Pendulums

 Looking at Barton's Pendulums. An interesting problems on why they move the way they do. Amazed at how many nearly right explanations I got. #iteachphysics #Science #STEM

Determining the speed of sound

 Determining the speed of sound using a tube and tuning fork. We were impressed with the speed that we got - we repeated the experiment three times and managed similar values.

Seismograph

Seismic Waves are easy to understand but the fact that a seismograph pen stays where it is whilst the machine moves isn't. #iteachphysics #Science #STEM

Notes and lengths of tube

 How does the length of a tube affect the note. Yes I could use a sonometer but the trombone is much more fun. #iteachphysics #Science #STEM

Speaker and square plate

 I always enjoy this experiment with the speaker, square plate and some salt or sand vibrating #iteachphysics #Science #STEM

Video of the Space Tube in Action

 

Getting Old and Hearing loss

 I am seeing how becoming more mature (ok old) that when I put the lid on the Space Tube I can't hear the sound let alone when I remove the air. Fortunately the students still have good hearing and tell me. #iteachphysics #Science #STEM
