Determining molecular mass


 Heating a gas syringe to 100C using steam from a steam generator and then adding a known mass of a volatile liquid allows us to determine its volume and, thus, its molecular mass.

Vector Analysis


 A ball is thrown into the air, reaches maximum height, and then falls to the ground. It is videoed, and using @pascoscientific Capstone, the motion is analysed, and vectors are drawn on it to describe the motion. Amazing what can be done in an hour.

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.

Set up for molten electrolysis

  Setting up ready to do electrolysis of a molten substance. Most of these are too dangerous to do in the lab and require a fume cupboard to...
