science in everyday life
cup of tea
The everyday cup of tea: where's the science in that?
Thermal convection occurs to transfer heat in a fluid. Evaporation causes some particles to gain sufficient energy to change state from liquid to gas (and accounts for the same particles then condensing on my glasses and fogging them up so I can't see what I'm doing) The metal teaspoon will conduct heat to our hand more quickly than the ceramic cup which is a better thermal insulator. And if we need to take a cup of tea out and about on our travels, then we probably use a thermos flask to keep it hot for longer.
Science is used to isolate the compounds within tea to study how they add taste or contribute to health. It also identifies ideal storage conditions so that we can avoid food poisoning from the milk. We also use alternatives to sugar to minimise tooth decay while still satisfying our sweet tooth!
Studies have even been carried out to determine the ideal biscuit for dunking.
We can also carry out investigations to determine whether we should add milk or let the tea cool a bit.

kicking a football
There's so much science in a game of football! Just think about the physics of impact and motion and all the energy transfers which occur. Then we can consider the biology which keeps a player fit and healthy, how they exercise and recover using massage to remove lactic acid from fatigued muscles with ice baths to speed up healing. Player's nutrition and training schedules are carefully planned and monitored. Biology also keeps the grass pitches looking good too. Finally chemistry is used to design high performance materials for the fabrics used in the kit and boots too.
