Various solids are lowered into a beaker of water. How does the water level rise in each case?
Imagine different shaped vessels being filled. Can you work out what the graphs of the water level should look like?
Can you draw the height-time chart as this complicated vessel fills with water?
Can you work out which processes are represented by the graphs?
Explore the relationship between resistance and temperature
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?
Analyse these beautiful biological images and attempt to rank them in size order.
Starting with two basic vector steps, which destinations can you reach on a vector walk?
Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents.
Which countries have the most naturally athletic populations?
Can you sketch graphs to show how the height of water changes in different containers as they are filled?
How much energy has gone into warming the planet?
To investigate the relationship between the distance the ruler drops and the time taken, we need to do some mathematical modelling...
How would you design the tiering of seats in a stadium so that all spectators have a good view?
Formulate and investigate a simple mathematical model for the design of a table mat.
A problem about genetics and the transmission of disease.
Explore the properties of perspective drawing.
Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?
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?
This problem explores the biology behind Rudolph's glowing red nose.
Work with numbers big and small to estimate and calculate various quantities in biological contexts.

Can Jo make a gym bag for her trainers from the piece of fabric she has?
Investigate circuits and record your findings in this simple introduction to truth tables and logic.
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. . . .
In which Olympic event does a human travel fastest? Decide which events to include in your Alternative Record Book.

Simple models which help us to investigate how epidemics grow and die out.
If I don't have the size of cake tin specified in my recipe, will the size I do have be OK?
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. . . .
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.
Can you deduce which Olympic athletics events are represented by the graphs?
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.
