**Hellooooo My Little Sweeties,**

**There is so much maths you can do with m&ms, it’s hard to believe there is any other sort of maths.**

**You can study:**

**Counting, times tables,** **set theory,** **Bar graphs,** **Fractions, % and decimals**, **Mean, median, mode, ****and parabolas (using a really cool peg-powered catapult).**

**But my favouritest ,developed by Patrick Len, is using m&ms to demonstrate half life in radioactive substances and therefore write an exponential equation.**

**m+m ACTIVITY:**

**Throw a fixed no. m&ms on a table. Mathspig chose 128 m&ms for a very good reason. Eat the ones with the m showing. Count remainder. Throw again. Eat the ones with the m showing. Count remained. Keep doing this. You will end up with results like the following. (Not identical as chance is involved)**

**Wow! m&m’s and exponential equations. How yummy is that!!!!!!**

**More yummy maths:**

**m+m maths 1: find the volume using m+ms!**

**m+m maths 2: Guess, NO, calculate the number of m+ms in a jar!**

**m+m maths 3: how many m+ms will kill you?**

**m+m maths 4: How many m+ms will kill my dog?**

**m+m maths 5: how many m+ms will kill my cat?**

**m+m maths 6: How many m+ms will kill my pet rat?**

**m+ms maths 7: how many m+ms will kill my pet mouse?**

**Mmmmmmm! Can’t talk. Face full of chocolate.**

**Bye bye**

**Are you bored by doing volume calculations?**

**Are you looking for a new and exciting way to calculate the volume of, well, things maths teachers ask you to calculate the volume of? Like what? You know, cubes or cylinders or cones or stuff. Well, today mathspiggies, we have the perfect solution for you. Yes!**

**We will calculate volume by counting m&ms!!!! Do I hear any complaints???? Anyone!!! Right!**

# WARNING: You may need a ship load of m&ms!!! Just saying.

Mathspig salutes CWanamaker for doing maths over and above the call of duty by actually measuring how many m&ms fit in various containers. He has provided us with the RPR (RAndom Packing Ratio) for m&ms(below) and you will find his experiments here.

**Two things you may need to know:**

## 1 fl ounce (US) = 29.6 ml

## 1cm^{3} = 1 ml

If you are like me, mathspiggies, you will be amaaaazed how many m&ms it takes to fill, say, a coffee mug. Nevertheless, you can calculate the volume from the no. of m&ms and you will find the answers here:m&m maths answers

Of course, mathspiggies, we can do the reverse maths and cheat … and use our superior maths skills to calculate the no. of m&ms in a cookie jar and then you WIN the cookie jar full of m&ms at the school fair.

#### LD50 of Theobromine in cats is 200mg.

#### According to The Royal Society of Chemistry cats are hypersensitive to Theobromine but, as cats cannot taste sweetness, they are rarely poisoned.

Theobromine is the poison found in chocolate. The LD50 is the Lethal Dose for 50% of animals to die. The LD50 information for mice can be found at The Toxicology Data Network

**Aussie physicist and TV present – that does sound like an oxymoron – Reuben Meerman (A meer man after all. Old joke) had an article published in the BJM (British Medical Journal) with Andrew Brown describing where fat goes when you lose it.**

**When you burn fat which is a triglyceride or a three-pronged hydrocarbon the formula is:**

**You breath out the FAT as CO2 and H2O.**

**BUT:**

**Oxidizing 10 kilos of human fat requires inhaling 29 kilos of oxygen to produce 28 kilos of carbon dioxide and 11 kilos of water. You can check out how much carbon dioxide you add to the atmosphere when you diet in the following graph:**

** **

**When you lose weight you add carbon dioxide to the atmosphere, but when you gain weight you take carbon dioxide out of the air. Your carbon footprint from Time for Change blog (See table below) can be neutralised if you put on the following weight:**
