Using a Fuel cell

 Using a dual fuel cell to split water into hydrogen and oxygen from solar energy and then to reverse the system and power a fan from the same hydrogen and Oxygen #iteachphysics

Using a Baffle to improve a ripple tank results

 One of the problems with using a ripple tank is unwanted reflections. Simply placing a piece of paper towel stop the unwanted reflections leading to better and clearer results. #iteachphysics

Using a Demo eye

Using the @pascoscientific demo eye to practically look at how the lens in the eye works by changing shape, and looking at different lenses for long and short sightedness. I really great bit of kit. #iteachphysics

Repairing Lung Machine

After a few years of use my lung demo broke, but with a new y piece, new balloons and new elastic bands and gaffer tape the lung demo has been rebuilt and is again working well, to demo to more students.

Using Mechanics to help with A level Maths



 Doing practical mechanics to help understand A level Maths. Playing with practical mechanics brings a level of realism to the Physics Maths problems, so the students can see and feel what is going on.

Newtons Second Law

 


One of my favourites - which ball will hit the ground first. Even with the evidence some students still don't believe it. Using a strobe to get the proof.

Using a prism

 Some brief bright sunshine through a crack in the curtains through a prism across the classroom wall The picture gave us about 15 different colours when seen as a jpeg #iteachphysics

Inverted test tube retains liquid


 Sometimes it is the little things that amaze students. During electrolysis they filled test tubes with solution, inverted them and were surprised when the liquid did not come out.

As to why this causes quite a discussion

Ticker Tape Timer

 Ticker tape timer. When introducing students to motion I find this is a great way to get the students to understand what is going on, make charts to stick in their book and then move on to electronic forms of recording. #iteachphysics

Electrical Choices


Which Fuse should I use? How safe is a UK Plug? What is a trip switch? - Frightening ideas and choices from students.


Drexel University chemical engineers create a new Li-S battery that outperforms rival Batteries.

A group of Drexel University chemical engineers have found a way to introduce sulfur into lithium-ion batteries which has improved the capabilities of the battery. The discovery is a new way of producing and stabilizing a rare form of sulfur that functions in carbonate electrolyte, which is the electrolyte gel used in commercial Li-ion batteries. This development would not only make sulfur batteries commercially viable, but they would have three times the capacity of Li-ion batteries and last more than 4,000 recharges. Previous versions of the Li-S batteries have already been shown to have improved performance in experimental settings using an ether electrolyte, rather than using the traditional carbonate. But these batteries are not be commercially viable. Replacing the cathode in Li-ion batteries with a sulfur one would alleviate the need for sourcing cobalt, nickel and manganese, which are toxic.

Using the Pasco weather Sensor in the Storm Eunice


 Using the Pasco weather Sensor in the Storm Eunice



Storm Eunice

 My @pascoscientific weather sensor ready and recording the weather and wind speeds. Just going to leave the sensor outside and stay inside today. #StormEunice #iteachphysics

Modelling a Lift

 Creating an Attwood Machine to simulate a lift. Took the students ages to work out why it wouldn't connect to @pascoscientific Capstone. Looked at motors attached and the changing force required.

Titrations

 Learning to do accurate titrations is important. Rather than doing one we have a go at doing 20-30 getting better and better learning new skills. We start practising with water to improve accuracy. #iteachchemistry #Science #STEM

Spark from a wimshurst machine

 

Trying to capture the spark from a Wimshurst machine is far more difficult than I imagined. I had to take loads of photographs to get one. I tried using the video and capturing an image but that has not as good as I wanted, but high speed motor drive got it every time.

Plasma Ball

 One of things I left out in the classroom for the students to find out and play with and start asking questions.

Halide tests

Testing for the halides, first was distilled water no halide, then surprised students, tap water with chlorine, to kill off the bugs, then chloride bromide and iodide

Maxwell's Wheel

Playing with potential energy to kinetic energy with some rotational energy thrown in, to give the A level physicists a hard day

Making a pH curve

 Using the @pascoscientific drop counter and pH probe, Temperature senor and chemistry sensor and the electric conductivity probe, to make a pH curve with the students using Capstone.

Newtons Cradle

 I was surprised how many students didn't predict what would happen in newtons cradle. I was amazed how many students hadn't seen one before. #iteachphysics

Heart Dissection

 Heart Dissection. Looking at the valves and the flow. From looking at the heart the students had to "wire up" the heart correctly. #Science #STEM

Force on a wire

 Looking at the force on a wire as we investigate magnetic fields around wires. Connecting a Ohaus balance to @pascoscientific Capstone and the magnetic field sensor. #iteachphysics

Using the FLIR Camera

 Using a FLIR camera to show heat conduction. We could see the thermometer on each rod and the rate of conduction, but the FLIR camera made all the difference. #iteachphysics @chatphysics

Transformers

 Transformers. Playing with different types. Making your own. Trying them out. That what the students need.

Using Snatoms

 Using @snatoms to quickly demonstrate natural polymers and how they form dipeptide bonds. So much quicker and easier to build these molecules with Snatoms when in a time constrained lesson. #Science #iteachchemistry

Quickfit Glassware


 Getting out the quickfit glassware to set up a distillation apparatus to show the year 10  so we can do a distillation. The students always seem amazed at the glassware. It will be the Kipps apparatus next.
