Procedure:
- Use the data given in the table in the previous activity to draw a graph.
- Take age as an X X-axis and per cent growth in height on the Y-axis.
- Mark the point representing your age on the graph (Let the age of a girl be 11 years, height be 120 cm).
- Find out the percentage of height already reached and calculate the height she might eventually reach
” Reaching The Age Of Adolescence Class 8 “
Observation
” Height Growth During Adolescence “
At the age of 11 years (girl), the point of age touches the 88% mark on the height axis. So, the maximum height that will eventually be reached
Present height / % of full height at this age x = 100 = 136.36 cm
Conclusion: From this activity, we conclude that we can determine the maximum height that would be reached at the end growth period using the formula.
