In this trail, a new type of NRICH resource, learn about
transformations of graphs. Given patterns made from families of
graphs find all the equations in the family. What biological
growth processes can you fit to these graphs? 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? Explore
displacement/time and velocity/time graphs with this mouse Can
you work out which processes are represented by the graphs? Can
you sketch graphs to show how the height of water changes in
different containers as they are filled?
