How the National Grid Works

 #Physics Teaching how the National Grid works https://youtu.be/P0j5VeRtGKo using a step up and a step down transformer or not and watching it fail. My pylons I am told make the difference. #iteachphysics #Science #STEM

Fermentation

 Turning all that sugar into alcohol and Carbon dioxide. One of the fun practicals learning about microbes and fermentation.

Trying out electronics

 #Physics Learning about electricity is learning what does work and what doesn't. Here practical work, seems far better than doing the theory. The students learn more and faster, here using Locktronics #iteachphysics #Science #STEM @MatrixTSL

Good storage = Rapid deployment

 Really useful these boxes for storing all the experiments. They stack well and the different sizes mean that they are more efficient in the storage/space ratio. Makes easy to find as we work on an experiment on demand system. As the students arrive they say I learnt about this today but I didn't understand it, we didn't do an experiment, so we can rapidly get out the experiment and let the student carry out the experiment and lean by doing and by discovery.

Mobile phones in lessons

 Many teachers don't like phones in their classrooms. Some are afraid their lesson could be recorded. I like my students to use their mobile phones in the lab. They record all my experiments. The good and the bad. My students Record the experiments, they take photos of the set ups. They enjoy taking Slo-mo of fast and not so fast events and using the phone as a microscope. Amazingly they usually organise themselves that one student does the recording and passes the files around. They act very responsibly and I have never had any problems. On the contrary the opposite is true. #STEM #Science #iteachphysics

Water Clock

 I need a much better water clock to do this experiment Rule of odds - Todays job. A cart is rolled down the track. As it passes a bell it rings the bell. We try and make the time between each bell ring the same. As the cart is accelerating, the gap between each bell gets larger. in the ratio 1:3:5:7 etc Once this is set up then I use water coming out from a tap to fill up different measuring cylinders. The amount of water is in the ratio 1:4:9:16:25

Flame Tests

 Flame Tests are one of my favourite topics. Explaining the colours of fireworks to year 8 in an online lesson.

Crimson Lithium

Lilac Potassium

Yellow Sodium

Red Strontium

Apple Green Barium

Green Boron
