Why Wind Power With a Paper Fan works

Use Wind Power With a Paper Fan as a practical way to explore prediction, fair comparison, and evidence-based conclusions. Use a hand-made paper fan to move a lightweight paper target and explore how distance and fanning speed affect motion. Keep the first round centered on the move from having the child place a lightweight paper target on a clear table to having them fan gently from one fixed distance.

Set up — Place a lightweight paper target on a clear table

Prepare paper before the child is asked to place a lightweight paper target on a clear table. If the child is unsure how to place a lightweight paper target on a clear table, simplify the setup before introducing the request to fan gently from one fixed distance. Use household-safe materials and keep the setup stable, supervised, and easy to clean up during both of those opening steps.

Step 2 — Fan gently from one fixed distance

Keep the adult prompt brief while the child tries to fan gently from one fixed distance. If needed, return to the earlier step to place a lightweight paper target on a clear table before asking them to observe how far or how fast it moves.

Step 3 — Observe how far or how fast it moves

Keep the pace slow while the child tries to observe how far or how fast it moves. If the effect is hard to see, simplify that action before continuing with the instruction to change only the fan distance or speed.

Step 4 — Change only the fan distance or speed

Treat the attempt to change only the fan distance or speed as a checkpoint between the earlier step to observe how far or how fast it moves and the coming step to repeat and compare. A perfect answer is not required.

Step 5 — Repeat and compare

After completing the instruction to repeat and compare, pause and ask what changed from the earlier step where they had to change only the fan distance or speed. Use that answer to decide whether they are ready to repeat and compare.

What to notice before Repeat and compare

The activity is working when the child uses what happened while trying to observe how far or how fast it moves to make sense of the request to change only the fan distance or speed. That is where what changes when one condition changes and what stays the same becomes visible.

Make Observe how far or how fast it… easier or harder

An easier round can stop after the child has tried to fan gently from one fixed distance; in that version, run one clear comparison with obvious conditions. For more challenge, repeat the test, measure more carefully, or change one variable only while keeping the path to repeat and compare recognizable.

Finish after Repeat and compare

Stop once the child understands why the sequence finishes with repeat and compare. There is no need for a harder finale; browse the activity search or make a related activity with the activity generator.
