PERÙ

Page 2: ACTIVITY

The total annual rainfall is 10 mm in the coastal area and about 1,000 mm in the mountainous area. The annual amount of precipitation in Lima, Matucana and Milloc, is 10mm, 270 mm and 660 mm respectively.

Place Annual rainfall (mm)

Lima 10

Chosica 24

San Mateo 38

Milloc 660

If flood occurs in Lima from rainfall in Chosica, what might be the height?

Page 3: ACTIVITY

• 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 = 1000cm3

• 1000cm3 is equivalent to 1000ml, then converted to 1 l

Task 1

Task 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 = …………. cm3

Task 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.

Page 7: ACTIVITY

Task 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?

Page 9: ACTIVITY

It is necessary to take from the context, some information that may be used for the development of

the mathematical processesAt first analyze the change of 10mm to 24mm rain, and

then analyze the change when the height Increases.

Task 3

The area of San Mateo is 133 km2,and if the rain causes a landslide, will it reach Chicla district, where we are located?(sopl 38 mm por m2 pero 5054x106)

Page 12: ACTIVITY

Task 4

San Mateo is from 38mm and the area is 133km2. How long will be the confined of the flood on the route?Calculate the volume of water.Convert the volume in km.
