The leap of faith pole is

Session Plan: Leap of Faith (Numeracy)
Session plan total time: 2 hours
Activity Time: 1 hour
Outdoor Classroom Time: 1 hour
Time
Plans
10 minutes
45 minutes
Get ready, Harness and helmets.
Leap of faith session, everyone should have at least one go, possible 2 if doing
tandem and time permitting.
Pack up remove kit.
After doing the activity, each person in the group to estimate the height of the
pole. From the group find out the tallest and shortest estimate and work out the
range of the estimates.
Workout the amount of steps it takes to do 20 metres per child by pacing 20
metres. Then workout the distance covered per step.
Workout the height using pacing: Demonstrate the Ruler technique: Hold a ruler so
it is the same height as the pole vertically with their arm straight. Now turn the
ruler so it is horizontal with one end at the base of the pole. Next get a friend to
stand at the other end of the ruler. Get your friend to pace from that point to the
leap of faith pole (In pairs pacing to the pole). Each one to pace from the given
position to the pole. Record this number, then multiply this by distance covered per
step. From each child results find out the tallest and shortest result and workout
the range. Explain the significance of getting a smaller range.
Explain how to work out the height using a clinometer using diagram provided.
Workout the values of A (distance to the pole when clinometer reads 45 degrees)
and B (distance from floor and eye level) from the diagram for each child, add this
together to work out the height of the pole. Workout the range of this method,
figure out which method is the most accurate and why.

Leap of faith.
Name:………………………..
Estimate the height of the pole: I think it is ........................... tall.
From our group the tallest estimate is…………….
From our group the shortest estimate is………….
The Range of our estimate is………………………
Can you find out the height of the leap of faith using these methods?
Pacing
Using Clinometers
Pacing: I do …............... steps for 20 metres.
One of my Steps =
20
=……………….
……………………
Pacing: Hold a ruler so it is
the same height as the pole
vertically with your arm
straight. Now turn the ruler
so it is horizontal with one
end at the base of the pole.
Next get a friend to stand at
the other end of the ruler.
Get your friend to pace from
that point to the leap of faith
pole.
One of my Steps = ………….cm
Line of Site
Pace to the pole=…………..Steps
One of my steps= …………….cm
Pace to the pole =X…………….
Our tallest result was…………………..
The leap of faith pole is ……………..cm
Our shortest result was………………...
The leap of faith pole is ………….metres
The range of our results is …………….
Clinometers:
Stand at the point where the top of the pole is at 45° according to the clinometer. You have now
created an isosceles triangle.
Find out these values:
A = Distance from you to the pole =......................
B = The height from the ground to your eye =..........................
