Simple Harmonic Motion

With a @pascoscientific Force Sensor at the top of a spring and an Ultrasonic Motion sensor at the bottom, the phase relationship between force, distance, velocity and acceleration can be examined and taught online within minutes.

Mitosis


 Slide making and staining and then trying to look for mitosis happening. Trying to find the different stages of mitosis is quite tricky at this magnification. This was one of the best slides.

How useful is the CG50 Geometry


 Just how useful is the Geometry App in the CG50? It seems to be quite good for GCSE Maths but I am not really sure it is worth the effort for A-Level Maths. Sure it can do some clever things, but the interface is hard to use so no marks here.

Learning to test Chemicals


 One of my favourites - identifying the unknown chemical. First flame tests, then chemical tests to determine the unknown. The Silver Nitrate test came out particularly well. I sometimes can't tell the Bromide from the Iodide, but in this case, I could.

Input / Output devices


Input / Output devices - easy in A-level computer science until questions like this come along, then it gets more fun. What specialized input and output devices are used in fields such as medicine and engineering?

 

Using a spectroscope to look at Helium

Using a @pascoscientific spectroscope to look at the discharge of Helium. After using a hand held spectroscope I now know what the students are looking at. #ScienceTeacher #Spectroscopy #STEMEducation

The velocity of a wave

#FunFact: You can determine the velocity of a wave in 2 ways! Use your phone's SloMo to measure distance and time OR use the wavelength and frequency relationship. Bonus: compare circular and straight wave speeds! #Physics #WaveVelocity

  1. To determine the velocity of a wave, you can use the slow-motion (SloMo) feature on your phone's camera to measure the time it takes for a wave to travel a known distance. By dividing the distance traveled by the time it took to travel, you can calculate the velocity of the wave.

  2. Another way to determine the velocity of a wave is to use the relationship between its wavelength and frequency. The velocity of a wave is equal to the product of its wavelength and frequency. By measuring the wavelength and frequency of a wave, you can calculate its velocity. Additionally, you can compare the velocities of circular and straight waves to determine any differences in their speeds.
