TASK ;- Your task is to draw a graph using the information given below and then to
use your graph to answer the questions.
 During this assessment your teacher will be looking a 2 things

1. Use the information to draw a scatter graph
with a line of best fit.
2. Most populations are kept in check by other
factors (the human population is an
exception). Name 2 factors that might keep
the population of rabbits in check.
3. Why do you think the human population has
increased so much in the last 100 years.
4. Continue your graph to estimate the number
of people in the year 2025.
5. The rate at which the human population is
growing is considered a great problem. Why
do you think this is?
6. How might the growth of the human
population be slowed down in the future.
7. In various places around the world, there are too many people and not enough food. How does
this affect the people in these areas?
8. Wars often cause people to leave an area. This is called migration. The same word is used to
describe animals leaving an area. What might cause foxes to migrate.

Teachers Notes
Level 4 – Results shown in graph form this may be bar graph or simple line graph
without named axis or a line of best fit
Level 5 – Results shown in a line graph with named axis. Some attempt to draw a
line of best fit.
Answers to questions show sound understanding
Level 6 – Results shown in accurate line graph with appropriate scale and named
axis. Units are included and there is an accurate line of best fit drawn.
Answers to questions show good understanding .
Level 7 – Results shown in accurate line graph with appropriate scale and named
axis. Units are included and there is an accurate line of best fit drawn.
Answers to questions show detailed understanding and ability to
transfer knowledge of animal populations to human populations.
