K'NEX Measuring Wheel
You can you use your K'NEX Measuring Wheel to measure distances - around your house, around your school or elsewhere.
Distances are measured in rotations of a pointer on the model, but you can convert "rotations" into a dimension such as metres or feet if you wish.
The model requires:
1. A K'NEX base kit, and
First, assemble the eight 3D connectors shown in the photo opposite.
Please visit Handy Hint A4 if you need help to do this.
Then assemble the two sides of the frame
and join them using four green rods.
Next, build the axle support shown in the photo
and this similar one.
Now, add to a red rod:
1. A snap cap black.
2. Two silver spacers.
3. An orange connector attached to a blue rod.
4. Two more silver spacers.
Then add the first axle support
and the second axle support, followed by:
1. a silver spacer.
2. a tan clip, with the pin facing outwards.
Then add the assembly into the frame.
The photo opposite is taken from the front
.. And this photo is taken from the back.
Now build the wheel assembly, by adding to a yellow rod:
1. A snap cap black.
2. A red connector.
3. A tan clip, with the pin facing away from the red connector.
1. The wheel, with the pin of the interlocking clip pushed into one of the small holes in the centre of the wheel.
2. A silver spacer.
3. A red connector.
4. Another silver spacer.
5. A tan clip, with the pin facing away from the red connector.
And finally add:
1. A blue gear, with the pin of the interlocking clip pushed into one of the slots in the centre of the gear.
2. A snap cap black.
Finally, add the wheel assembly into the frame.
Your Measuring Wheel should now look like this from the back
and like this from the front.
To test your Measuring Wheel:
1. Hold your Measuring wheel by the handle, and run the wheel along any flat surface.
2. You can measure the distance travelled by the wheel by counting the number of times the blue pointer has turned around. For instance, the side of a house may measure 10.5 "turns" of the pointer.
3. It is quite easy to calibrate your measuring wheel by running it along a tape measure, to find out how long 1 "turn" is in centimetres or inches.
4. You might then use this information to draw a map of your garden or school grounds.
5. Note that you can measure the lengths of vertical surfaces as well as horizontal surfaces.
