Sonometer

 #ALevel #Physics My new Sonometer from @SciChemEdu arrived. Typical science equipment no manual at all. Now need to devise the best experiments to use the machine rather than being given best examples. #iteachphysics #Science #STEM

Ionic Bonds

 #GCSE #Chemistry Teaching about ionic bonds using shapes I made using a @ScanNCutUK machine. The activity worked well with the students creating all sorts of correct formulae for compounds. #Science #STEM

Blood Pressure

 #GCSE #Biology Blood pressure is always hard to explain but using a pipette and glass tubing and a syringe it became so much easier. #iteachbiogy @chatbiology #STEM #Science #BloodAndWater

Cannon Problem

 #ALevel #Physics The physics of shooting the invading navy from the top of the cliff. Simplifying the numbers - no calculators concentrating on the problem. Trying to get more maths into the Physics. #iteachphysics #STEM #Science

Chemistry is fun

 Student: I hate Chemistry!!

Chemistry is

more fun with whizzes, pops and bangs. Student I love Chemistry!!! #STEM #Science #Chemistry

Intro to Digital Microscopy

 #GCSE #Biology A great introduction to microscopes using a digital microscope connected to the PC looking at clothes, money, books. Students so excited with what they see. So many ways better than compound microscope #STEM #Science

Measuring the Mass of a Ruler

 #ALevel #Physics Measuring the Mass of a @pascoscientific Ruler using Moments, then comparing it to the measured mass on a balance - pretty accurate to 2dp. #iteachphysics #Science #STEM

Boyles Law

 #ALevel #Physics Turning up the pressure on the students looking at Boyles Law. #iteachphysics #Science #STEM

Balancing Equations

 #ALevel #Chemistry Balancing Equations. The students were having a problem with the first one. Now I know its a bit more of a challenge but not too difficult!!!!

I use Can't Be Asked

Can you do it? #Science #STEM #iteachchemistry

Here are the answers

Demonstrating a Convection Current in Air

Demonstrating a Convection Current in Air

Convection Currents

#GCSE #Physics Looking at Convection Currents with two chimneys and a tea light. The smoke is sucked down one tube and up the other. Nice illustrative experiment. #iteachphysics #STEM #Science

 

Burning Calcium

 #Science Burning Calcium in Air. After burning Magnesium what could be better than burning a piece of calcium. Loved by the students. #STEM #Chemistry

Cheek Cell

 #GCSE #Physics #Biology Looking at some cheek cells down a microscope. Microscopes can be fun - using a digital microscope to look at ties, blazers and jumpers introducing the world we can see then onto cells #STEM #Science

Pushing a mass

 A Mass on a String #GCSE #Physics. I only used a 1kg mass because although I know it won't hit me, I am always that little be scared that I might push it just a bit and ... #iteachphysics #STEM #Science

Wilmshurst Machine

#GCSE #Physics Getting the Wilmshurst machine out to do its party piece this week. It can do all the experiments the Van der Graff generator does, and student powered. #iteachphysics #STEM #Science

Podcast Reducing Emissions

 

Scientists are calling for emissions in Carbon Dioxide to be cut by 7.6% per year. This means that by 2030 the Carbon Dioxide emissions will be cut by half. The scientists are also calling for a 3% a year cut in extracting coal, oil and gas - effectively leaving the reserves in the ground. But at present rather than a drop in production, the production has actually increased worldwide. During the pandemic most people thought that there would be a cut in emissions with few cars and planes travelling, but with people at home more emissions were produced.

Philip and Paul also look at "Orca", the name of Climeworks' new direct air capture and storage plant in Iceland. It will take carbon dioxide removal to the next level by combining direct air capture technology with the underground storage of carbon dioxide. Orca will capture 4000 tons of Carbon Dioxide per year - making it the world's biggest climate-positive facility to date. 

Safer heating Limestone

 How do you make your wire baskets to hold Limestone when heating it into Calcium Oxide - wind nichrome wire around and around. Sometimes I try to wrap as a parcel. - with mine the wire always expand lots and sometimes the limestone falls out? The Horizontal Bunsen stops limestone falling in if bits fall off. Then the Bunsen doesn't get damaged.. #STEM #Science #GCSE #Chemistry

Heating Light and Dark Surfaces

 Two surfaces one black and one silver heated by a light bulb. Simple to set up and excellent results captured on @pascoscientific  thermometers and Capstone. #GCSE #Science #Physics #iteachphysics

Electroscopes

 #Alevel #Physics Getting ready for the photoelectric effect - the cheap electroscope works brilliantly with a full deflection and the expensive one won't budge today - now to find the UV Lamp #iteachphysics #STEM #Science

DVD in a Mirror lies

In my last post I looked at a DVD reflecting the light. But what happens if you put a mirror next to the DVD. The colours are changed. No surely a mirror reflects what you see so whay are their different colours in the mirror. I know you think this is a fake so try it yourself and see that this really happens.

DVD Diffraction

 Simple ways of looking at the diffraction of light using an old DVD, doesn't cost anything and gives students a problem trying to explain why it works as it does. #Physics #iteachphysics #STEM #Science

Burning different Alcohols

 #GCSE #Chemistry Burning different Alcohols and looking at the flames. Talking about covalent bonds with #Snatoms

Decarbonising the world

 

Decarbonising the world isn't about getting rid of the carbon - that’s impossible, but it all about managing the resource. Carbon Taxes can be applied to industries to push them in the right direction allowing the more efficient companies to trades carbon credits with other companies by setting caps and allowing trade. Carbon Coins are used to reward companies for not emitting carbon. The systems all come down to money. Either raising money in the form of taxes for those companies who must make carbon  dioxide as part of their business like the cement industry and paying  other companies who might be investing in wind and solar power. Generating this revenue means that the money can be spent on research and infrastructure and justice. Changing what we do needs to be done, and it needs to be done quickly.

Mechanical disadvantage

 #ALevel #Physics looking at Mechanical disadvantage in a knee/elbow joint, from a Lamb Joint to @pascoscientific tension protractor to measure the forces at different lengths from the pivot. #iteachphysics #Science #STEM This lesson works well in Biology as well so the studemts doing both subjects benefitted.
