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

Fractional Distillation

 Crude Oil fractional distillation. Looking at many different types of fuels and why to use or not use them.

Vacuum

I can't understand why I can't pull these apart. There is nothing in there holding them together.

Electrical Conductivity

This is not usually the first sensor I think of to use but for many physical and chemical reactions the @pascoscientific electrical conductivity probe provides an insight into the composition of the solution. #STEM #Science

Air Pressure in a Balloon

 What is the air pressure inside a balloon? The students were amazed at the answer using a @pascoscientific wireless pressure sensor and Capstone to prove the pressure didn't really change. #teachphysics #STEM #Science
