Question - Why would Palouse Waterfall not be in exactly the same place in 1000 years time?
Use the worksheet above to complete Tasks 1 - 4 below.
Task 1 - Study the Google Map to the right and write down some locational information for Palouse Falls. (country, state, closest big city). Then find out how high the falls are in metres.
Task 2 - Watch the YouTube video to the right. He's a bit of a crazy dude.
So, he went over the edge and survived. If someone else were to try and equal his record in 1000 years time, they would have to go to a slightly different location - but why?
Task 3 - Complete these tasks on your worksheet.
i. What are the key ingredients for a waterfall to form?
ii.Write a 50 description of how a waterfall forms.
iii. Where is the last waterfall you visited?

Task 4 - Produce a three sequence cartoon strip to show the formation of waterfalls using Palouse as your example. Each cartoon strip must be fully annotated and include a scale (height in metres). You can do this on the last page of your worksheet.
Task 5 - Waterfall Research
Click on the blue tab below right to access a worksheet where you are to research some of the most famous waterfalls in the world.
You will need to find a photo, find out the height (vertical not horizontal - in metres) and the country.
When you have completed them all, mark on the positions of all 10 onto the world map.
The next activity is all about Victoria Falls & Devils Pool. Follow the instructions carefully and enjoy both of the videos.
Task 6 - Now watch the video opposite.
This is taken close to the base of Niagara Falls near to the plunge pool and if you look carefully, you should be able to see the following features:
1. Bands of hard and soft rock.
2. The overhang.
3. Evidence of the material that has fallen from above.
