Analog Book revision

Just got the updated #AnalogBook! Packed with new insights on analogue circuits & DIY projects. Perfect for my students since time is a rare commodity. Loving this free upgrade! #CircuitProjects #EdTech

Cleaning Water

 Turning pond water into something a bit cleaner. Still loads of bacteria and other nasties but much of the other stuff was removed.

Titrations

Me: Ever titrated, A-level student?

Student: Just once.

I ensure they experience 5-6 sessions, perfecting their technique. They make up their solutions, and we verify the concentrations via titration. A fun learning journey! #ChemistryEducation #Titrations #LearningByDoing

Solar furnace

The first trial of the solar furnace. Will it raise the temperature of the water by a few degrees? Aligning it seemed a bit problematic and very crude. Maybe I should mount this on an equatorial mount with a motor to follow the sun

Mechanics - Maths meets Physics

Mechanics: the grand meeting of Maths & Physics! Using strobe light & a ball drop for gravity-acceleration calculations and SUVAT for the final velocity. #PhysicsIsFun #MathMagic

Sounds

 Investigating the shapes of the waveforms for different instruments. Comparing the waveforms for the instruments with their counterparts on a digital organ. Virtually identical

Fossil in a Rock

 I have shown students fossils before but it wasn't until I showed the students this fossil in a rock that they really understood how fossils were made and how they were found. Seeing is believing.
