Part 1: How are exponential growth and decay present in the real world? Give at least 2 examples for exponential growth and 2 examples of exponential decay.
Part 2: View and comment on the work of at least 2 other students. Try to choose students whose work is based on different realworld examples than the ones you chose.

Ms. Sue,
exponential growth: dandelions
decay: garbage 
math 
fluffy,
can you explane it ms. sue

math 
Steve,
exponential growth means that the rate of increase is proportional to the present amount. As more and more dandelions spread their seeds, the patch grows faster and faster, since each new flower contributes more new flowers to the population.
Same for decay. As the amount decaying shrinks, there is less and less to contribute to the disintegration. Radioactivity is a common instance, but maybe not quite so available in everyday life.
