Two Nodding birds

 Two Nodding birds. Identical Mass , Liquid etc. But they have very different periods. Why? Something to get my A level #Physics Students thinking about (they can play with them as well) #iteachphysics #science #stem A bit of fun to get them interested.

3-D printing

 Holidays are about catching up on 3-D printing #Physics equipment for the @pascoscientific sensors to do more/better/clearer experiments and designing some new bits of my own. #iteachphysics #science #stem

Newtons Laws of motion

#GCSE A level #physics Using a strobe to take pictures of two ball bearings falling one vertically and the other pushed horizontally. #science #stem #iteachphysics

 

making alloys

 #GCSE chemistry. When we talked about making alloys the students didn't expect the petri dish, washing up liquid and straws to come out. Making bubble structures of Alloys. #science #stem

Law of Odds

GCSE #Physics Trying out measuring acceleration using bells and a cart travelling down a @pasco.scientific track using our 3D printed bells and a sound sensor since a water clock didn't work well because my reaction times were too slow. The sparkvue software which is free on Android and IOS gave some very good results. #iteachphysics #science #stem

 

garlic and mint as anti-microbial agents

 Some success with our A level #microbiology #biology practical looking at garlic and mint as anti-microbial agents. 1 out of 8 worked - Under identical conditions the bugs do as they please. #science #STEM One of the discs Garlic managed a 1.5cm ring of lysed bacteria.

interferometer

A level #Physics First build of the interferometer. Using a
@pascoscientific
mini loudspeaker connected to a signal generator and a wireless sound sensor and a motion sensor to measure the length of the extension. #iteachphysics
