Doing Titrations the easy way

 #Chemistry Doing Titrations the easy way showing the temp and PH curves using @pascoscientific drop counter and Capstone. Students can see the reaction going on rather than finding an arbitrary end point. Good discussion. #Science #STEM

Calorimeter

 #Physics Setting up the calorimeter ready to work out the energy in foods. Sir, "Why are we doing chemistry and Biology in Physics?" #iteachphysics #Science #STEM

Chemistry Shells

 Looking at electrons in shells with year 8. Watching the light dawn on faces as Lithium and Fluorine combine by donating and receiving elections. Magic #teachchemistry #Science #STEM @ChatChemistry

Centre of Mass

 #Physics Centre of Mass. The students asked why I had a hanging basket indoors. Now they know. The used phones as inclinometers and looked at the stability of masses at different heights. #iteachphysics #Science #STEM

Westminster Electric Motor

 #Physics Demonstrating the Westminster Electric Motor. The students wind the coil and create a set of brushes and get the motor to work. Using Flemings left hand rule to work out the direction of rotation. #iteachphysics #Science #STEM

Simple Electric Motor

 #Physics #GCSE Looking at Flemings Motor Rule and how electric motors work starting with this very simple design. #iteachphysics #Science #STEM This design is nothing more than a coil of wire resting on two pieces of wire and a strong magnet. According to Flemings Left Hand Rule when a wire carrying an electric current comes into a magnetic field then movement happens.
