Tutoring in your own home, at your own convenience

Today's schooling doesn't allow room for individual learning, which means that students who don't suit the pace of the whole class can fall between the cracks. If students aren't achieving at the level they are capable of, their learning can stall, leading to boredom and frustration. Their confidence can suffer and they won't enjoy school as much as they should.

I can help. I offer personal tutoring in a range of subjects for NCEA and Cambridge International Exams, and can provide students with the skills and confidence they need to achieve their potential.

I'm based in Auckland and will come to your home at a time that suits you, for maximum convenience and maximum learning. Because the home is a familiar environment, it's where the student is the most comfortable – this is an important part of enjoying learning.

Field Trips

Treasure Hunt

After nine and a half years the treasure remains unfound.



20 September 2018 – Into The Underworld

Into The Underworld is back on! An exhibition of laser scanned images of Auckland's lava caves held in Silo 6 in Wynyard Quarter, Into the Underworld (www.intotheunderworld.nz) gives a unique view of Auckland's volcanic heritage, and shows just how close our lava caves are to suburbia.

The images themselves are stunning, with some up to five metres tall, and others up to seven metres wide. The exhibition is open daily noon to 9pm and runs until Monday 1 October 2018.

6 September 2018 – Acetylene

When using acetylene it's really important to know what you can and cannot do. Acetylene is a flammable gas – indeed, known for its particularly hot flame – and like many flammable gases it's dangerously explosive at the right combination with air (or with pure oxygen). That last bit is really important... and basic science. It means acetylene has to be stored and used carefully.

Acetylene also has the interesting property that if you pressurise it to about 2 atm it can spontaneously explode, decomposing into other stuff like hydrogen and carbon. To avoid that happening, acetylene cylinders contain acetone, a liquid in which the acetylene dissolves. Copper catalyses this reaction, so copper and brass fittings should not be used. The cylinders need to be used vertically so the acetone does not come out.

This is pretty straight forward stuff, but on Monday 3 September two people missed applying the simple science and a father of three children died. The NZ Herald detailed (warning, graphic details) how it happened: a guy put acetylene and oxygen together in an LPG cylinder and his friend didn't stop him from going back to it.

In July 2017 I talked about how a lack of basic science knowledge caused the deaths of 15 people from a cornflour fireball. As I said at the time, science enriches lives, broadens horizons, and can save lives.
