MATHS IN SCIENCE
MATHS IN PHYSICS – MOVING CAR
CONDITION
A car starts from 0 m.
After 1 second it is at 3 m, after 2 seconds at 12 m, after 3 seconds at 27 m.
TASK
Which mathematical model best describes the motion of the car, and what does the increasing distance represent?
MATHS IN CHEMISTRY – GAS PRODUCTION
CONDITIONDuring a chemical reaction, gas is produced over time:
at 0 min = 0, at 2 min = 5, at 4 min = 12, at 6 min = 20.
TASK
What type of mathematical relationship best describes the gas production, and what does the increasing slope mean?
MATHS IN BIOLOGY – BACTERIA GROWTH
CONDITION
A bacteria population grows like this:
1 hour → 4 bacteria, 2 hours → 8, 3 hours → 16, 4 hours → 32.
TASK
What mathematical model describes this growth and what does doubling mean?
