Working Model of Heart

Teaching GCSE Biology using a model heart to demonstrate the circulatory system. I find that only half filling with red liquid better shows the direction of the flow.

Resonance with Tuning Forks

 Two identical tuning forks, one resonance box and a ping pong ball to show how the second tuning fork picks up the sound from the first. #iteachphysics Having fun with physics doing some practice before the lessons.

Darkbox

 A level/GCSE #Physics Using a Lightbox as a Darkbox for looking a optics experiments in the lit classroom. Using here a @pascoscientific light source and a Prism to split up light. #iteachphysics @ChatPhysics

Refraction

 A level/GCSE #Physics Refraction an alternative way- works well on a visualiser #iteachphysics @ChatPhysics Good as an intro along with the glass of water and the arrow changing direction. This introduces refraction of different liquids.

More Resistivity

 Using the @pascoscientific from @SciChemEdu wireless motion sensor for distance and the voltage/current sensor for the resistance and plotting the resistance against distance for A level #physics prep #iteachphysics Got to see if the experiment works.

Inverse Square Law

 A level #Physics An easy way to understand the inverse square law. Get a spray can 10cm away spray for 1 sec, move 20cm away spray 1 sec and repeat at 40 and 80cm. The circle gets larger - same amount of paint, - measure the area. Pi radius squared. So as the volume is the same but the circle is larger we can work out the ration of the areas as the distance doubles. #iteachphysics

Using a Stroboscope to freeze a cord

 Using a Stroboscope to freeze a cord vibrating as a stationary wave. Doubling the strobes frequency we could see the forward and reverse wave in A level #Physics #iteachphysics

Lenz's Law

 Lenz's Law

Using magnetic film to show the passage of the magnet down a copper tube. #iteachphysics #teaching Using some slomo to help.

magnetic field viewing film

Using magnetic field viewing film from https://magnametals.co.uk to show the magnetic fields produced by a magnetic without having to use all those messy iron filings. The film is great made from a green flexible sheet coated with micro capsules containing nickel flakes suspended in oil.

Learning electricity

 Using Locktronics to teach series and parallel circuits. So easy for the GCSE students to understand Drawing, Reading, Doing, seeing patterns, the best way to learn, using all types of learning and recall. #iteachphysics #education

Ready for Microbiology

 Something I haven't done for a while - Microbiology with my A level Biology students. All the equipment has now arrived, so we can soon start sterilising ( the autoclave was too big for the photos) making up broth and agar plates, practising aseptic technique and starting to grow some E Coli then we can test them with Mint and Garlic to see if they like the food as much as I do! #microbiology #teaching #teachingkids

Density

 Measuring Mass and Volume to calculate the Density of different materials. Looking at GCSE #Physics to compare the ease of solids liquids and irregular shaped objects to determine their densities. The mass of a block of tungsten shocks the students. #iteachphysics

My renewable Energy News

The CO2 from the fermentation of just one six pack of beer takes a tree two full days to absorb. Young Henrys have developed a system to use microalgae to produce oxygen from this. https://myrenewableenergy.org/News.html  July 7th #ClimateAction #beer

Investigating Capacitors at A Level

 Trying out some A level #Physics experiments to understand the properties of capacitors, changing the size, dielectric, distance between plates and voltage. Having Fun #iteachphysics #teaching

Smartcart as an Oscillator

 Damped simple harmonic motion using a

@pascoscientific

smartcart from

@SciChemEdu

recording the force/distance/acceleration/velocity onto capstone for 1:1 remote A level

session on #Physics #iteachphysics #teaching

Simple Harmonic Motion Pendulum

 Investigating more A level #Physics Simple Harmonic Motion using @pascoscientific metre rule and the rotary motion sensor. The students were finding out how changing the mass and the length of the pendulum affected the period. #iteachphysics

Furure Foods

 New Video on Future Foods. https://youtu.be/IJXQmMu_IRE

We look at what foods will will need to consider eating in the near future. #climatechange #ClimateTwitter #education

Force table

 Teaching A Level #Physics online using a force table. The student needed to tell me which hander to add and remove masses to achieve balanced forces. With some students still isolating it is essential that they do some practical work #iteachphysics

Making a Salt from an insoluble metal oxide and Acid

 A busy morning making Copper Sulfate from Copper Oxide and Sulfuric Acid. The students enjoy doing the practicals they are not able or allowed to do at school. This one is a required practical that the school only told them about. #teaching I made a full video of this on YouTube which is very popular.

Human Eye

 Using the @pascoscientific model of the human eye to teach A level #Physics students about how the les in the eye works and how glasses solve problems in the eye. #iteachphysics

Changing the shape of the lens in human eye model

 Using the @pascoscientific adjustable lens in the human eye model and with ray boxes. Its great to be able to show the biology and physics students how the human eye lens works getting thicker and thinner rather than using fixed shaped lenses. #iteachphysics #teaching

The lens consists of two sheets of plastic with water in the middle and connected to a syringe. If water is pushed into the eye the lens gets fatter and becomes convex in shape. As water is removed the lens becomes concave in shape.. Adjusting the amount of water changes the dioptre of the lens. Fascinating to watch and use.
