T HE TOTAL ANNUAL RAINFALL IS 10 MM IN THE COASTAL AREA AND ABOUT 1,000 MM IN THE MOUNTAINOUS AREA. T HE ANNUAL AMOUNT OF PRECIPITATION IN L IMA, M ATUCANA AND M ILLOC, IS 10 MM, 270 MM AND 660 MM RESPECTIVELY. PlaceAnnual rainfall (mm) Lima10 Chosica24 San Mateo38 Milloc660 If flood occurs in Lima from rainfall in Chosica, what might be the height?

T ASK 1 What is the volume of water equivalent of 10mm? Filled with water to a height of 10mm, a container of 1m long and 1 m wide. Calculate the volume V = AXH, V = 100cmx100cmx0, 1cm = 1000cm cm 3 is equivalent to 1000ml, then converted to 1 l

T ASK 2 Filled with water to a height from 10mm, to 24 mm, to increased 2mm each and calculate the volume V = AXH, V=100cmx100cmx...cm = …………. cm 3

w (cm) l (cm) H (cm)Volume (cm3) Litres , , , , , , ,4

T ASK 3 The meaning of 1mm annual rainfall. Fill 1 l of water into receptacles with different dimensions. Compare the level ofthe same volume of liquids in these different containers. Model: Observe that the water height is lower as the base increases.

T ASK 4 If the length of the receptable increases by 5 cm each, which is the change of the level of water? Which is the change that causes the height to decrease each time? VolumeWidth (cm)Length (cm)High (mm) , , , , , , , , ,8
