Ammonia and HCl

 Doing the safer way of showing the reaction of Ammonia with HCl. The relative size of the molecules can be appreciated more. #Science

Ores

 

Making Copper from its ore. Looking at a piece of native copper found in Cornwall and some real Malachite ready to crush up and make copper. Making it more real for students. #iteachchemistry #Science #STEM

Wave Energy

 We see waves all the time but it takes a machine like this to show that the particles in the wave only go up and down and its the energy that moves along. #iteachphysics #Science #STEM

Reversible Experiments

 Making experiments reversible Looking at Hydrous and Anhydrous Copper Sulfate. I was surprised when the students found out we to repeat this experiment over and over again without loss. #iteachchemistry #Science #STEM

Terminal Velocity

 Getting some great Terminal Velocities with a mass falling in a tube of water using a @pascoscientific rotation sensor and Capstone. #iteachphysics

Titrations

 Having fun using pipettes, digital pipettes and titrations using burettes and @pascoscientific drop counter and Capstone. Letting the students play with old and new technology and comparing the accuracy. #Science #STEM

Ligands

 I love doing these experiments. Such pretty colours. My favourite is the Ammonia with Copper Sulfate

with that deep blue, but all are beautiful.
