reaction rate: marble & acid

visitors this year: 96 Rates: marble and acid Apparatus Clamps, bosses, & stands, marble pieces (large, medium and small sizes), 1M hydrochloric acid HCl, flask, bung, delivery tube, a good gas syringe. Interface, position...

oscillator motion

visitors this year: 37 Oscillator motion A position sensor is attached to a weight and spring assembly as shown. This can be used to study simple harmonic motion and the effects of changing the...

extension of a spring

visitors this year: 75 Extension of a spring A position sensor is attached to a weight and spring assembly as shown. This can be used to graph the extension of the spring with increasing...

seismometer

visitors this year: 78 Seismometer The magnetic field sensor responds to magnetic fields. We can use this idea, together with a metre rule damped with a sand bag, to demonstrate how a seismometer might...

pendulum & simple harmonic motion

visitors this year: 181 A position sensor can be used to study this. The sensor is attached to a weight and spring assembly as shown. This can also be used to study the effects...

when do plants grow

visitors this year: 113 It’s not easy to measure how fast a plant grows. You would probably not be too keen to take measurements every few hours – and especially not overnight. There are...

monitor breathing

visitors this year: 223 Is your breathing steady while you sit restfully? How does it change when you talk? How does it change when you exercise? How quickly do you recover after exercise? To...

simple harmonic motion

visitors this year: 36 Simple harmonic motion is rarely as simple as the lesson title implies. This potentiometer-based sensor measures angles as its core rotates. Attaching a ruler as shown (or hack saw blade)...

position or angle sensor

visitors this year: 70 This sensor allows superb and easy to do investigations into the swing of a pendulum leading on to studies of harmonic motion and damping. (See several examples nearby). It allows...
