Count the total number of cubes now on your lab table, and record this number in your data table in the same row as for other data for that year. Return all cubes in your current population to the can 7. Repeat steps 3-6 for 9 more years. Return all cubes to the can, and plot the population growth for your population with a colored pencil, with years on the horizontal axis, and size of the population on the vertical axis. Count them and remove from your population, and return them to the stockpile.
White cubes represent a female who have just borne a child.
These should be counted, and for each white cube, add one more cube to your population from the stockpile. The cubes with green faces up represent a group of individuals in which only half of them bear a child. The other half are females who successfully have practiced birth control. Count the number of green cubes and divide by two. Also add this number of cubes to your total population.
