Prep for mocks

Prep for A-level year 2 mocks. Not done differentiation and Integration, so can only do about 1/3 of the paper since most of the paper is A level, not AS, so many of the students are only able to do AS questions, not the harder A level ones.

Wave Particle Duality

What is light? How many colours are there.?Are some colours just the figment of the mind like red and green light makes yellow? Is white light real, or is it made up of other colours? And is it a wave or a particle? So many questions to find answers to.

 

Biomass

Calculations of Biomass. How many aphids on a leaf? What percentage are infected? The mass of one aphid multiplies up compared to the mass of the tree.

 

Sorts and Searches

 How do sorts and searches work, and what are their advantages? Mechanically modelling them to see how they might work gives the students another way to visualise what is going on.

Online lessons

 Teaching online with Zoom. We can still do experiments, but they are harder by remote control or have to be demos. But still, with a selection of cameras and tools, we can still make great lessons to be remembered.

Electrolysis

AQA required practical electrolysis but quite a few year 11 students had not done it so after a quick refresher on the theory they had a go and correctly predicted the chemicals and successfully tested for oxygen, hydrogen and chlorine gases.
 

Changing air Pressure

Could you change the air pressure with just the heat in your hands? The @Pascoscientific Pressure sensor could detect the change in pressure, and the thermometer recorded the change in temperature as the Pressure went up from 99.1 kPa to 100.1 kPa
