Resonance Tube Apparatus
- Let your class measure the velocity of sound in the air! After partially filling the resonance tube with water, sound a tuning fork of known frequency at the tube's open upper end. Then the water level can be adjusted until the air in the tube resonates at the same frequency as the tuning fork, increasing the volume of the sound.…

Second Law Of Motion Apparatus
- To demonstrate the Second Law of Motion simply and accurately, two identical balls one drilled, and the other solid is used. When the release lever is triggered, the internal spring accelerates one ball and releases the other, showing that two balls dropped from the same height hit the ground at the same time even though one is traveling forward when…
