Inverse Square Law
A level #Physics An easy way to understand the inverse square law. Get a spray can 10cm away spray for 1 sec, move 20cm away spray 1 sec and repeat at 40 and 80cm. The circle gets larger - same amount of paint, - measure the area. Pi radius squared. So as the volume is the same but the circle is larger we can work out the ration of the areas as the distance doubles. #iteachphysics

Ready for Microbiology
Something I haven't done for a while - Microbiology with my A level Biology students. All the equipment has now arrived, so we can soon start sterilising ( the autoclave was too big for the photos) making up broth and agar plates, practising aseptic technique and starting to grow some E Coli then we can test them with Mint and Garlic to see if they like the food as much as I do! #microbiology #teaching #teachingkids
