Aphid lifecycle

 Black flies and green flies are attacking the plants. Now seems an excellent time for the students to investigate life births and how they feed through the phloem. This is a great homework investigation for the movement of stuff in plants.

Golden Rain Experiment

The Golden Rain Experiment! Watch as Lead Iodide precipitates out of the solution, swirling in the flask like golden rain falling.  #ScienceExperiment 

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.
