1Use the data to plot a chart or graph. The first thing you need to decide on is whether you will use a bar chart or a line graph. Also, make sure you label the axes clearly. Make your horizontal axis go up to 20 years.

Use your chart or graph to answer the following questions.

2Mark grew very quickly at two times in his life. Times when people grow very quickly are called growth spurts.

aBetween which ages did Mark have his first growth spurt?

bBetween which ages did Mark have his second growth spurt?

cDo you think that all people have growth spurts at the same time?Explain your answer. You might consider other people in your class or in the year above.

3Marks mother forgot to measure him sometimes. From your graph, what height do you think Mark was when he was:

a3.5b9c14?

4Mark stopped growing when he was 19. Extend the line on your graph so that you can estimate what height Mark is now. Write down your estimate of his height.

5aWhat happened to the number of cells in Marks body as he grew?

bBy what process does this happen?Year 7 2014/2015 Key Stage 3 Science Unit: Reproduction
