Can you suggest a curve to fit some experimental data? Can you work out where the data might have come from?
Formulate and investigate a simple mathematical model for the design of a table mat.
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?
Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents.
Which units would you choose best to fit these situations?
Get some practice using big and small numbers in chemistry.
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.
Estimate these curious quantities sufficiently accurately that you can rank them in order of size
Work out the numerical values for these physical quantities.
How much energy has gone into warming the planet?
Make an accurate diagram of the solar system and explore the concept of a grand conjunction.
Work with numbers big and small to estimate and calculate various quantities in physical contexts.
Simple models which help us to investigate how epidemics grow and die out.
Investigate circuits and record your findings in this simple introduction to truth tables and logic.
When you change the units, do the numbers get bigger or smaller?
Work with numbers big and small to estimate and calculate various quantities in biological contexts.
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 sketch graphs to show how the height of water changes in different containers as they are filled?
Make your own pinhole camera for safe observation of the sun, and find out how it works.
Can you work out which drink has the stronger flavour?
Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?
Can Jo make a gym bag for her trainers from the piece of fabric she has?
Examine these estimates. Do they sound about right?
Explore the properties of perspective drawing.
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. . . .
What shape would fit your pens and pencils best? How can you make it?
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?
Can you work out what this procedure is doing?
Which dilutions can you make using only 10ml pipettes?
Where should runners start the 200m race so that they have all run the same distance by the finish?
Use trigonometry to determine whether solar eclipses on earth can be perfect.
Andy wants to cycle from Land's End to John o'Groats. Will he be able to eat enough to keep him going?
Can you deduce which Olympic athletics events are represented by the graphs?
How efficiently can you pack together disks?
Various solids are lowered into a beaker of water. How does the water level rise in each case?
An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see?
Is it really greener to go on the bus, or to buy local?
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?
Work with numbers big and small to estimate and calulate various quantities in biological contexts.
These Olympic quantities have been jumbled up! Can you put them back together again?
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. . . .
How would you design the tiering of seats in a stadium so that all spectators have a good view?
