Exothermic reaction of Zinc and Copper Sulfate

 Using @pascoscientific capstone to capture the temperature change when Zinc is added to Copper Sulfate. The cooling rate can easily be measured and the total heat extrapolated. #iteachchemistry #Science

Rate of reaction of carboxylic acids

 Short experiment looking at the Rate of reaction of carboxylic acids - ethanoic and propionic reacting with Magnesium Ribbon. Which is the fastest?

Testing for Carbon Dioxide

 Testing for Carbon Dioxide Online. Resisting the student saying blow harder. #Science

Snatoms

 Using @snatoms to made models of the molecules we are using. Very fast to make and so easy to change into different versions of the homologous series. #iteachchemistry #Science #STEM

Rates of reaction

 Looking a the reactive rates of propionic and ethanoic acids with a twirl of magnesium ribbon. The ethanoic acid was very much faster.

New Oscilloscope

 Trying out my new oscilloscope before I do any experiments with the students, so I am confident in its use and what the buttons do and there are lots on this one #iteachphysics

Measuring the resistance of a length of Wire

 Getting ready to do the resistance is proportional to the length of wire practical. Using a rheostat to visualise the system in a smaller space. Using the Locktronics by @matrixtsl to simplify and explain the circuit
