Perpendicular Gradient Rule

I was going through some AS Maths Questions with some students and I was surprised that none of them had met the Perpendicular Gradient Rule

Gradient of Line 1 x Gradient of Line 2 = -1 if perpendicular

Heating and Cooling

Heating and Cooling using a couple of @Pascoscientific wireless thermometers linked to Capstone to capture and print out the data. The students were deciding on whether black or white radiators were the best.

 

Ready for Microbiology

 Kit's sterilized, broth brewed. Agar slopes set, plates poured. All set for students to dive into learning aseptic technique! #ScienceInProgress #LabReady

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
