Carbon Nanotubes


 This is not a model in the molymod range, but one  I made to shown how graphene can be rolled up into a carbon nanotube. It gave the students much to discuss about new materials and composite materials. Making bullet resistant material was a fun topic to look at these materials.

Pasco Spectrometer

There are many favourite practicals, but seeing the spectrum of light from different glowing chemicals is certainly one of them. The @pasco.scientific spectrometer gives an insight into an unseen world around us.

Templates

 ​Templates are sometimes useful for science and maths. This one helps with the 3D drawings, especially of prisms, although not so good for life like diagrams. Others help get better drawing of science equipment.

Acceleration due to gravity

We had a go at determining the acceleration due to gravity. First time got this answer  Perfect results using @Pasco Light gate and Picket fence

Look into my eyes


 Using a close up camera to see how the iris works and using the @pasco human demo eye to see how it works in practice by putting in an iris in the eye. It is also useful to use a camera lens to show the camera T-stops in action.

3 Liquids


Three different liquids. All looked like water but they were not what the students expected. I was surprised how many students naturally assumed a clear liquid would be water.

Investigating the Iris


Needing to get up close and personal, looking at how light affects my iris

How the eye works



 By changing the amount of water in this @pasco lens used in the demo eye model the students were able to use the same lens to create both concave and convex lenses and gain a better idea how the eye worked.

Using chemix.org

Using Chemix.org to create the practical guidelines for some of the experiments. The students seem to easily follow the diagrams and set them up correctly.

Resonance

 Making a lot of noise and some pretty shapes in the lab #iteachphysics

Sometimes we just need to get the pullies out in Maths.


Maths is largely an abstract subject, but sometimes when studying subjects like Mechanics, then it is necessary to get the pullies out to improve our understanding of the problem and then the quality of the learning increases dramatically.

Rapid V/I Curves

 Using @pascoscientific voltage-current sensor with the wireless airlink to create a very fast V/I straightline for a resistor and a not so straight line for a bulb.

Goldleaf Electroscope




 I really hadn't appreciated how hard it would be to get a gold-leaf electroscope working. The first model I had used dutch metal and I couldn't get it to work, but this model with real gold leaf did work eventually with me leaning how to attached the gold leaf properly. Putting the gold-leaf on is really quite difficult until you know how.

Woolly Human Gut


A few years ago my wife knitted the entire human gut. It is popular with the students as it is fun to hold and it is life-size so they a sense of the scales and proportion of the gut. It also fits in an abdomen sized clear bag which shows more what if looks like in the body.

Specific Heat Capacity

 Managed 4 specific Heat capacity experiments, Copper, Brass, Aluminium and Iron in 1 hour using @pascoscientific wireless thermometer and Joulemeter from @SciChemEdu  #iteachphysics

Looking at Hydrides


Using @Snatoms to look at the hydrides comparing their properties and looking at hydrogen bonding.

Investigating Heating and cooling

Investigating Heating and cooling using a couple of @pascoscientific wireless thermometers and Capstone. The difference was very dramatic and was much better than using a Leslie cube and different coloured cans. #iteachphysics

Using an Oximeter

 One of the fun things we do, testing whether the students have a heartbeat and their Oxygen stats. Some students with painted nails appear to be dead!



Sunday 10 April 2022

Investigating the energy in different fuels


 Looking at different alcohols to see how they compare. The equipment doesn’t work well due to the heat loss, so it is up to the students to design a better experiment.

Equation of a Circle


 Using the equation of a circle and a point on the circle to work out the equation of a tangent.

Ninja star 2


Unlike the last Ninja star video where the Ninja star is on the VdGG this time its the electrons from the Ninja star that are being used to neutralise the charge on the Van de Graaff generators dome and this causes motion.

The Ninja Star


The Ninja Star is actually called a Hamilton's mill but in physics it's called a Electrostatic pinwheel. The reason it gets spinning is because the spinner is positively charged, like the dome. Each point has a strong electric field around it. Air molecules close to the points lose electrons and become positively charged ions - their electrons were attracted to the points and used to neutralise some of the charge on the dome. Positively charged ions are repelled by the positive star's points and move away. The points move in the opposite direction (Newton's 3rd law) so the star Spins.

Thermoelectric Converter


Having some fun with the thermoelectric converter, Ice cold water on one side and near boiling water on the other and getting the fan to spin for quite a while, then repeating with different temperatures in both and timing the fan movement.

Sonometer


Using a sonometer to tune a string to a particular frequency using a paper hanger, looking at the relationships between length, tension and thickness on the pitch.

Covalent Bond Revision


 Using @snatoms to help with GCSE Chemistry Revision. The models are so quick to made and the students really enjoy these so much more than other s we have. We made dozens of models in a few minutes.

Faradays Laws


Investigating dropping a magnet into a coil. Changing the number of turns, changing the speed of the magnet and changing the polarity of the magnet to see what happens.

Total Internal Reflection


I find this one of Physics bits of magic how total internal reflection works. Creates lots of fun predicting what might happen and then trying it out and seeing that something else happens and then trying to come up with an explanation and a rule. Real Science

Electricity Revision
