Mathspig Outdoor Activities

Hellooooooooo My Little Wallaroos,

Mathspig has been reading The Last Child in the Woods by Richard Louv.  He describes school today as a form of ‘passive incarceration’. Too many children live their life indoors exposed to the ‘one-way experience of television and other electronic media’. Many rarely, or never, experience nature or just digging for worms in the garden. And sometimes nature is just around the corner. 

Mathspig lives 10 km from the CBD in Melbourne, Australia. Aussies often joke about riding kangaroos to school or warn of Drop Bears (Koalas that kill tourists dropping from trees). It’s our Aussie sense of humour. Those jokes almost seemed real when these kangaroos turned up by the Yarra river below Mathspig’s house recently. They’re wild roos. I saw them at 9am one Sunday looking at all the joggers, dog-walkers and cyclists on the nearby bike track. They didn’t seem worried. Awesome. Or, maybe, roo-some.

So outdoors we go, mathpiggeies, to embrace nature and have some grand maths adventures:

And don’t forget some Geometry Jokes.

Other outdoor maths adventures on this blog:

The shop is 50 Smoots on your left

Why not invent a new unit of length, make a string in, say, Smoots, and go outside and measure parts of the school.

Some students will discover their co-ordinate point is not on the grid. Students should then work out that they will need a different scale for the y-axis. You can get more inspiration at the Stand Again blog.

Death by Chocolate: The Maths

May 28, 2014

 Choco Yum Yum! Mathspig lervs chocolate. But did you know chocolate can kill you?

Chocolate contains a chemical called Theobromine. This alkaloid ( other alkaloids include cocaine, nicotine, caffeine and strychnine) can kill humans. More info Wired Magazine.

How much chocolate is too much?

Firstly, the darker the chocolate the more Theobromine it contains.

According to About Chemistry:

Based on highest possible toxicity:


wrapper crop 2White Chocolate: insignificant

.

.

wrapper crop 3

Milk Chocolate 1-5 g/kg

200gm block = 1 gm per block

……………………………………………………………………………………….

wrapper crop 1Dark Chocolate 10 g/kg

200gm block = 2gm per block

 ..

…………………………………………………….

??????????????????????????????????????Cooking or Baking chocolate* 10-50 g/kg

200mg block = 10 g per block

(* Vetmedicine: Cooking chocolate contains 8-10 times the Theobromine in Milk Chocolate )

According to Wired large doses of theobromine may cause “nausea and anorexia ….. sweating, trembling and severe headache.”

The Royal Society of Chemistry notes that chocolate does not contain caffeine, but theobromine induces similar symptoms.

LD50 for the lethal dose for 50% of the population f or Theobromine is:

1000 mg/kg 0r 1gm/kg of body weight in humans
