PROBABILITY

 Investigating probability: I look at the weather forecast and opinion polls for the election to work out the likelihood of rain, which party might win which seat, or whether I can roll six sixes.

Air Wedge

 Betting on how much mass I could lift with just air. None of the students had seen an Air Wedge before. Then moved on to Lego pneumatic systems to investigate how they work

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.
