Fuel Cells

 This fuel cell comes to bits, so we can take it apart, show how it works and then reassemble it and show it working. #iteachphysics

Making up stock Solutions

 Getting the students to make up the stock solutions. Year 11's work out the amounts for the volume and concentration. They learnt a lot and my technician didn't have to do it! #iteachchemistry @ChatChemistry

Testing for oxygen

 Making and then testing for oxygen. Fun of relighting a glowing splint in oxygen. #Science #iteachchemistry

Elodea Photosynthesis

 Using one of the photographic lights to really illuminate some Elodea getting it to produce significant amounts of Oxygen. Doing this experiment in the winter means little sunlight and its harder to get Elodea. #Science #STEM

Electricity and Magnetism

 Plotting the magnetic field around a single wire. #iteachphysics

Making salts from insoluble carbonates

 Making Salts from Carbonates. A good time to learn about magnetic stirrers and how they work. #Science

#teachchemistry #iteachphysics

Equilibria

A Level Chemistry looking at Cobalt Chloride in hot and cold solutions and how the equilibrium is changed #iteachchemistry #Science

Red + Green = Yellow

 Physics is watching the surprise on students faces when you mix red and green light and get yellow ... and they won't believe you saying it is a trick. These are A level students. #iteachphysics

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.

Ravens eye

Using the canon 70D on a gimbal with the ravens eye to get some steady shots of me teaching. I am known to move about a bit and the camera can follow me as I move across the studio

Redox

 Redox - A level Chemistry A Hard Saturday Morning trying to get the students to understand OILRIG

Oxidation is Loss of Electrons

Reduction is Gain of Electrons

Measuring a Magnetic Field

 Using the @pascoscientific Magnetic Field Sensor to explore different magnetic fields and designing experiments to do this. #iteachphysics

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

Creating a powered pendulum

 Creating a powered pendulum to look at resonance. We collected the data using a motion sensor and displayed in @pascoscientific Capstone. This gave numbers to the effect observed. #iteachphysics #Science #STEM

Maths Day.

Sorting out the Binomial expansion, and binomial probability. Its amazing what two weeks holiday, and Christmas can do to students brains. First Maths in 2 weeks.

 

Fluctuating Gravity Field?

 Using @pascoscientific Sparkvue and track and a Smartcart to work out a value of acceleration due to gravity. In my lab there seems to be a fluctuating gravity well, which seems to constantly change the value of g. #iteachphysics #Science

Air Wedge

 Using an Air Wedge to lift a Butane cannister #Science

Lime water

Setting up to test for Carbon Dioxide - perhaps one of the simplest tests. The students making their own limewater solution, is a good fun way of doing a test and means much more than just doing something. #iteachchemistry #Science @ChatChemistry #STEM

Putting the windings on the Acoustic Levitator

 Putting the windings on the Acoustic Levitator, then soldering. Its keeping us out of mischief.
