Pressure and Temp

 Fixed Volume. The flask is warmed, but the Bordon gauge doesn't seem to move. But add the @pascoscientiofic pressure sensor, and with much relief, we can see the pressure change with the wireless pressure sensor, which is a bit more sensitive than the Bordon Gauge.

Normal Distribution and Hypothesis Testing

 A-Level students find hypothesis testing the most challenging concept and type of math to understand. In the run-up to the last Maths Exam, this is what all the students ask about and need to go over again. 

Pullies

 Playing with Pullies Finding out that with an eight to one pully the mass of the rope balances a 3 kg mass.

Potometer

 A potometer is used to measure the transpiration rate of a plant. We started using a leaf, but a few gave much better results, and we tried in different wind conditions - powered by a fan and measured with an anemometer.

Analog Computing

 Analog Computers can easily do things that are complex in digital terms, and it is right that students should be exposed to all types of technology so that they can make informed choices in the future.

Kipps Apparatus

 The students had to figure out how the Kipps apparatus worked and what it could produce. Defeated, the use of the Internet improved things, and then a demonstration with Zinc and Acid explained everything.

Protecting the Ultrasonic sensor

 Protecting the @pascoscientific Ultrasonic sensor when investigating Simple harmonic motion of a weight on a vertical spring. Safety also protects the equipment as well as the students.
