Quadratics aren’t just equations to solve — they’re stories graphs are telling you
The discriminant reveals whether a curve crosses, touches, or misses the x-axis entirely.

Remember the disappearing cross?
We took it further with @pascoscientific sensors—measuring turbidity as sulphur forms in real time.
From “can you see the X?” to “here’s the graph!” hemelprivatetuition.blogspot.com/2025/08/the-...

Why does sweat cool you down?
We ran a @pascoscientific experiment using wireless temperature sensors, a fan, and a damp cotton pad to feel the science of evaporation.
A sweaty truth, revealed. hemelprivatetuition.blogspot.com/2025/08/pasc...

Today’s Python project: Rock–Paper–Scissors with emojis — plus a simple AI that tries to win! A fun way to learn logic & coding. Full blog hemelprivatetuition.blogspot.com/2025/08/buil... #Python #CodingForStudents #HemelPrivateTuition
A leaky copper pipe turned into a chemistry lesson! The blue corrosion inside wasn’t just plumbing trouble — it was a chance to identify copper compounds like a GCSE/A-Level chemist. Read the full story hemelprivatetuition.blogspot.com/2025/08/when... #Chemistry #HemelPrivateTuition
Fairground physics The chair-o-planes aren’t just fun — they’re conical pendulums in action! We recreated the ride with a bung on a string to measure centripetal force (with slo-mo too!). hemelprivatetuition.blogspot.com/2025/08/coni... #PhysicsInMotion #HemelPrivateTuition
Summer’s for sun, beaches, and a well-earned break — but it’s surprising how much students forget over the holidays! If you’re heading into Year 11 or Year 13, a little study now can make a big difference later. Keep your brain in gear! #GCSE #ALevel #HemelPrivateTuition
