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

Ionic Bonds

 #GCSE #Chemistry Teaching about ionic bonds using shapes I made using a @ScanNCutUK machine. The activity worked well with the students creating all sorts of correct formulae for compounds. #Science #STEM

Blood Pressure

 #GCSE #Biology Blood pressure is always hard to explain but using a pipette and glass tubing and a syringe it became so much easier. #iteachbiogy @chatbiology #STEM #Science #BloodAndWater
