SKU: B10633Tooth Tunes Kit
A Hands-on kit that teaches the principles of sound induction/conduction. When students bite on the wooden rod, the frequencies of the attached audio signal, from a radio, is then transmitted from their teeth to their ears. Includes activity material for five students and an instruction manual.
SKU: PH36197Trajectory Apparatus
This unique low cost trajectory apparatus allows the students to study the trajectory of a projectile. A steel ball launches from a ramp and collides with the target plate that is equipped with marking paper to record the point of contact manually. Move the target plate to different positions and the exercise is to plot the full trajectory of the ball. The kit consists of a wooden plotting board, two wooden supports, one steel ball, one cello tape role, four graph papers and four marking papers. The apparatus is provided with full instructions.
SKU: PH10517ATrans-Ratio
Trans-Ratio is a simple transformer system that allows students to investigate the relationship between primary voltage, secondary voltage and the turns ratio. The Primary coil has tappings at 200, 400 and 600 turns while the Secondary has 100, 200, 300, 400, 500 and 600 turns all brought out to 4mm sockets. An AC supply of upto 6 V as well as AC voltmeters are required for demonstration purpose.
