Investigations 1&2

Science Investigations 1 and 2 make it easy to cover
time consuming or difficult to set-up experiments
anywhere and in a fraction of the time taken in the
lab. Students can practise experiments before actual
lab work or use the program for revision.
Perfect for recapping on experiments carried out in

previous lessons and for introducing new work.
