A problem about genetics and the transmission of disease.
Simple models which help us to investigate how epidemics grow and die out.
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.
Can you suggest a curve to fit some experimental data? Can you work out where the data might have come from?
Andy wants to cycle from Land's End to John o'Groats. Will he be able to eat enough to keep him going?
Formulate and investigate a simple mathematical model for the design of a table mat.
How much energy has gone into warming the planet?
How would you design the tiering of seats in a stadium so that all spectators have a good view?
Learn about the link between logical arguments and electronic circuits. Investigate the logical connectives by making and testing your own circuits and fill in the blanks in truth tables to record. . . .
Work out the numerical values for these physical quantities.
Which countries have the most naturally athletic populations?
Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents.
Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?
Examine these estimates. Do they sound about right?
Get some practice using big and small numbers in chemistry.
In which Olympic event does a human travel fastest? Decide which events to include in your Alternative Record Book.
How do you write a computer program that creates the illusion of stretching elastic bands between pegs of a Geoboard? The answer contains some surprising mathematics.
Estimate these curious quantities sufficiently accurately that you can rank them in order of size
Use your skill and knowledge to place various scientific lengths in order of size. Can you judge the length of objects with sizes ranging from 1 Angstrom to 1 million km with no wrong attempts?
Explore the properties of perspective drawing.
Which dilutions can you make using only 10ml pipettes?
An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see?
Where should runners start the 200m race so that they have all run the same distance by the finish?
Work with numbers big and small to estimate and calculate various quantities in biological contexts.

Can you work out which drink has the stronger flavour?
Can you work out which processes are represented by the graphs?
Make an accurate diagram of the solar system and explore the concept of a grand conjunction.
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?
Imagine different shaped vessels being filled. Can you work out what the graphs of the water level should look like?
