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?
How much energy has gone into warming the planet?
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 physical contexts.
Which units would you choose best to fit these situations?
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?
Estimate these curious quantities sufficiently accurately that you can rank them in order of size
Work with numbers big and small to estimate and calculate various quantities in biological contexts.
Many physical constants are only known to a certain accuracy. Explore the numerical error bounds in the mass of water and its constituents.
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.
Investigate circuits and record your findings in this simple introduction to truth tables and logic.
Simple models which help us to investigate how epidemics grow and die out.
Work out the numerical values for these physical quantities.
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.
Get some practice using big and small numbers in chemistry.
Formulate and investigate a simple mathematical model for the design of a table mat.
How efficiently can you pack together disks?
Analyse these beautiful biological images and attempt to rank them in size order.
An observer is on top of a lighthouse. How far from the foot of the lighthouse is the horizon that the observer can see?
Explore the relationship between resistance and temperature
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. . . .
Can Jo make a gym bag for her trainers from the piece of fabric she has?
Can you sketch graphs to show how the height of water changes in different containers as they are filled?
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?
Work with numbers big and small to estimate and calulate various quantities in biological contexts.
Can you work out what this procedure is doing?
Examine these estimates. Do they sound about right?

Make an accurate diagram of the solar system and explore the concept of a grand conjunction.
Can you deduce which Olympic athletics events are represented by the graphs?
Are these estimates of physical quantities accurate?
To investigate the relationship between the distance the ruler drops and the time taken, we need to do some mathematical modelling...
Andy wants to cycle from Land's End to John o'Groats. Will he be able to eat enough to keep him going?
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?
Can you visualise whether these nets fold up into 3D shapes? Watch the videos each time to see if you were correct.
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. . . .
