Are these estimates of physical quantities accurate?
How much energy has gone into warming the planet?
Work with numbers big and small to estimate and calculate various quantities in physical contexts.
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?
Get some practice using big and small numbers in chemistry.
Examine these estimates. Do they sound about right?
Work out the numerical values for these physical quantities.
Use trigonometry to determine whether solar eclipses on earth can be perfect.

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.
To investigate the relationship between the distance the ruler drops and the time taken, we need to do some mathematical modelling...
Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?
