In which Olympic event does a human travel fastest? Decide which events to include in your Alternative Record Book.
Andy wants to cycle from Land's End to John o'Groats. Will he be able to eat enough to keep him going?
10 graphs of experimental data are given. Can you use a spreadsheet to find algebraic graphs which match them closely, and thus discover the formulae most likely to govern the underlying processes?
Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents.
Make an accurate diagram of the solar system and explore the concept of a grand conjunction.
Examine these estimates. Do they sound about right?
Can you work out which processes are represented by the graphs?
How much energy has gone into warming the planet?
Various solids are lowered into a beaker of water. How does the water level rise in each case?
Get some practice using big and small numbers in chemistry.

Work with numbers big and small to estimate and calculate various quantities in physical contexts.
Where should runners start the 200m race so that they have all run the same distance by the finish?
Make your own pinhole camera for safe observation of the sun, and find out how it works.

Two trains set off at the same time from each end of a single straight railway line. A very fast bee starts off in front of the first train and flies continuously back and forth between the. . . .
Work with numbers big and small to estimate and calculate various quantities in biological contexts.
Work out the numerical values for these physical quantities.

These Olympic quantities have been jumbled up! Can you put them back together again?
Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?
A problem about genetics and the transmission of disease.
Use the computer to model an epidemic. Try out public health policies to control the spread of the epidemic, to minimise the number of sick days and deaths.
In Fill Me Up we invited you to sketch graphs as vessels are filled with water. Can you work out the equations of the graphs?
Explore the properties of isometric drawings.
Imagine different shaped vessels being filled. Can you work out what the graphs of the water level should look like?
Is it cheaper to cook a meal from scratch or to buy a ready meal? What difference does the number of people you're cooking for make?
