They say education is a lifelong journey. Difficult to comprehend when you are at school slogging through lessons and exams but learning can be greater fun when turned into an educational game. Take a practical application and apply as many subjects that have been learned in the classroom.

This morning I took a shower, a frequent occurrence I hasten to add, but today I had one of those eureka moments - a tribute perhaps to that other rather more famous bather. Have you ever thought how much science is involved in the process of taking a shower?

To highlight the point I have used the following abbreviations as each topic appeared during my ablutions.

" Biology (B) " Physics (P) " Chemistry (C) " Maths (M) " Citizenship (Citi) " Psychology (Psy) " Geography (G) " Geology (Geo) " English Language (Eng)

The first question to loom up is why we take a shower? The experience is functional in removing body odours created by bacteria, (B) but also physiological as it induces endorphins that help wake you up and make you feel good (Psy) Removal of body odours also makes you a little less undesirable to others nearby ( City).

The water is fed from a header tank under gravity- thanks to Newton (P) - and as I'm a devout wuss, heated. Energy is consumed to heat the water by the conversion of electrical energy into heat P). This is measured in watts, the result of multiplying volts by amperes (M +P).

Responding to marketing persuasion I have been attracted to the delights of a power shower. The increased force (P) boosts the endorphins (B) but unfortunately uses 12 times the amount of water (Geo) than the gravity shower all of which has to be heated (P ) This is draining the natural resources, literally, of water and power causing environmental concerns (forgot to add the code for the environment - that's an (E). The availability of water depends on geography (G) and the natural storage which locally are aquifers (Geo).

Being male I have a predilection to B.o.g.o.f offers ( buy one get one free) in supermarkets and anything in blue packaging (Psy) The resultant over purchase of needless stock (M) led to a ban by my wife (City)that means all shower products used have her stamp of approval and sensible supply level.

Today's showering experience was a cornucopia of non blue ingredients. The shampoo promised a "Fruitful Infusion" to produce a "Dazzling Shine" (Eng) from the passion flower, patchouli and vetiver ingredients(B). The conditioner provided "Tangle free hair with uplifted volume" enhancing the dazzle effect by way of a "Citrus lift"(Eng) from tangerine, lemongrass and aloe vera (B) And the rest of the body below the head was in turn subjected to "Serious pampering"(Eng) from fennel (B) and sea mineral (C) based in a silky smooth shower gel (C).

The post shower application of talcum powder, contained talc mineral (C+Geo). The deodorant, promising to maintain a "desert - dry"(Eng) atmosphere under the arms (B +G) from aluminum zirconium trichlorohydrex (C). The aftershave contained alcohol ( C).

In the space of 5 minutes I had consumed 150 litres of water, 4 kilowatts of energy (P), half an alpine meadow of additives, and drained the lot away to the water treatment works where they will use bacteria (B) to break the ingredients free from the water, and off we go again.

Taking a simple shower will seem a lot busier from now on. My shower involved 34 applications of science and learning and a lot of fun to see how many links with education can be made.
