Twists in a string

 Looking at how twisting a string increases its strength #ALevel #Physics Compared straight and twisted fibres. Amazing difference. #iteachphysics #STEM #Science

Home Made Cyclotron

#ALevel #Physics My homemade cyclotron. Not quite as fast as the real thing, made from a clear mixing bowl, some copper conductivity tape Alt +positive and -negative and a Van der Graaff generator, with a graphite covered ping pong ball #STEM #Science #itechphysics

 

Crookes Radiometer

Snatoms and Covalent Bonds

 #GCSE #Chemistry Covalent bonding made much easier using the @snatoms. So much faster than other makes and 1000% better than the drawings. The students grasped the idea in seconds. #Science #STEM #iteachchemistry

Making Copper Sulfate Crystals

 #GCSE #Chemistry Time to make Copper Sulfate Crystals - one of my favourite practicals - Students love the colour change then the crystallisation then looking at the crystals, under the microscope. #Science #STEM #iteachchemistry

Sonometer

 #ALevel #Physics My new Sonometer from @SciChemEdu arrived. Typical science equipment no manual at all. Now need to devise the best experiments to use the machine rather than being given best examples. #iteachphysics #Science #STEM
