How efficiently can you pack together disks?
Investigate circuits and record your findings in this simple introduction to truth tables and logic.
The triathlon is a physically gruelling challenge. Can you work out which athlete burnt the most calories?
Can you visualise whether these nets fold up into 3D shapes? Watch the videos each time to see if you were correct.
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. . . .
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. . . .
Can Jo make a gym bag for her trainers from the piece of fabric she has?
To investigate the relationship between the distance the ruler drops and the time taken, we need to do some mathematical modelling...
Have you ever wondered what it would be like to race against Usain Bolt?
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 rank these sets of quantities in order, from smallest to largest? Can you provide convincing evidence for your rankings?
Is it really greener to go on the bus, or to buy local?
Formulate and investigate a simple mathematical model for the design of a table mat.
Can you work out which drink has the stronger flavour?
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.
Simple models which help us to investigate how epidemics grow and die out.
Can you suggest a curve to fit some experimental data? Can you work out where the data might have come from?
Which dilutions can you make using only 10ml pipettes?
Can you sketch graphs to show how the height of water changes in different containers as they are filled?
This problem explores the biology behind Rudolph's glowing red nose.
Can you deduce which Olympic athletics events are represented by the graphs?
Andy wants to cycle from Land's End to John o'Groats. Will he be able to eat enough to keep him going?
An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see?
What shape would fit your pens and pencils best? How can you make it?
What shapes should Elly cut out to make a witch's hat? How can she make a taller hat?
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?
In which Olympic event does a human travel fastest? Decide which events to include in your Alternative Record Book.
Can you work out which processes are represented by the graphs?
When you change the units, do the numbers get bigger or smaller?
Are these estimates of physical quantities accurate?
Work with numbers big and small to estimate and calulate various quantities in biological contexts.
Analyse these beautiful biological images and attempt to rank them in size order.
Explore the relationship between resistance and temperature
Work with numbers big and small to estimate and calculate various quantities in biological contexts.
Explore the properties of perspective drawing.
Imagine different shaped vessels being filled. Can you work out what the graphs of the water level should look like?
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?
These Olympic quantities have been jumbled up! Can you put them back together again?
Explore the properties of isometric drawings.
How would you design the tiering of seats in a stadium so that all spectators have a good view?
Can you work out what this procedure is doing?
Estimate these curious quantities sufficiently accurately that you can rank them in order of size
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.
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?
