# To be able to identify coastlines on a global scale

Which country has the longest coastline? L.O. To be able to identify coastlines on a global scale Must: be able to define what a

coastline is Should: be able to measure coastlines on a global scale Could: be able to rank the longest coastlines in the world

Prediction Which country has the longest coastline? What is a coastline? What is a coastline? A coastline is the

edge of the land where it meets the sea or ocean. Where is the coastline? Stimulus question Which country has the longest coastline? Using your atlas and handouts provided

Measure the length of each countrys coastline to answer the stimulus question Example: Brazil Step 1: Measure the distance, i.e. one point to another. .cm Step 2: Take your answer from step 1 and times (x) it by the scale of the map HINT: Scale can be written in numbers, words or a scale line

. cm X (scale of map) = Answer . cm Step 3: Your answer from step 2 is still in centimetres (cm). To convert this into kilometres (km) divide ( ) you answer from step 2 by 100,000 (as there are 100,000 cm in 1 km) HINT: Take off 5 0s or move your decimal place 5 places to the left Answer from step 2 ... cm 100,000 = Answer.. km This is your final answer!

Stimulus question Which country has the longest coastline? Using your atlas and handouts provided Measure the length of each countrys coastline to solve the stimulus question
