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

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
