Explaining Attached Image to a 6yr Old: Tips & Tricks
Click For Summary
Discussion Overview
The discussion revolves around how to explain a mechanical image involving gears and belts to a 6-year-old. Participants share tips and tricks for simplifying complex concepts related to mechanical systems, including the direction of rotation and the interaction between gears and belts.
Discussion Character
- Exploratory
- Conceptual clarification
- Technical explanation
- Homework-related
Main Points Raised
- One participant suggests using animated images and simple cylindrical objects, like wheels, to help visualize the concepts for a child.
- Another participant notes that the next gear turns in the opposite direction unless a non-twisted belt is used.
- A question is posed about determining whether a box will open or close based solely on the number of pinions in the structure, without tracking each one individually.
- One participant proposes a numerical method to solve the problem, mentioning concepts such as crank handles, meshed gears, and the effects of parallel and crossed belts on rotation direction.
- Another participant outlines two methods for solving the puzzle: drawing direction arrows and counting using tokens to track rotation direction changes.
Areas of Agreement / Disagreement
Participants express varying methods for explaining the mechanical concepts, but there is no consensus on a single approach. The discussion includes both numerical and visual strategies, indicating multiple competing views on how best to simplify the explanation.
Contextual Notes
The discussion does not resolve the effectiveness of the proposed methods, and limitations in understanding may arise from the complexity of the mechanical concepts involved.
Who May Find This Useful
Parents, educators, or anyone interested in teaching mechanical concepts to young children may find the tips and strategies discussed here useful.

Animated images are one way:
Using simple cylindrical objects (little wheels for example) on one another or with a cord to represent the belt (twisted or not) may help visualized as well.
In any case, the next gear always turn in opposite direction, except with the non-twisted belt.

Can you determine if the box will close or open without following the pinions one by one? Only by the number of pinions involved in the whole structure?

Yes you can do it numerically but it is not as safe.
Concepts needed, crank handle, meshed gears, parallel belts, crossed belts, and winch drum.
Where two gears mesh the rotation direction reverses.
Where a belt connects two pulleys there is no change of rotation, unless the belt is crossed.
There are two ways to solve this puzzle.
1. Draw more direction arrows as you work along the gears and belts of the mechanism.
2. Count using tokens such as “clock” and “anti”, flipping the token for every reversal.
Use = for a parallel belt, x is a crossed belt. c is clockwise, a is anticlockwise.
The sequence here is “ ca = acaca x cacac x aca ”
So output is opposite direction to input. The box opens.
