Try it and try again

Try it, look, fix one thing, try again.
The big ideaTry your steps, see what happens, fix one thing, and try again.

How it works

Nobody gets it right the first time, and that is fine.

Try it, see what happened, fix one thing, and try again.

Change one thing at a time, so you can tell what helped.

Make the stepsTry the stepsSee whathappenedFix one thingand around again
Round and round.

Example 1: The first try

  1. Mia winds the spring one time and lets go.
  2. The plane drops near Bo's feet.
  3. She looks closely and sees that the spring is too loose.
  4. One try is only the start.

Example 2: Fix one thing

  1. Mia changes only the winds, to three.
  2. The plane flies farther but lands in a bush.
  3. Better, not perfect yet.
👣one wind: near Bo🌳three winds: the bush🏡five winds: over the fence
Each try goes farther.

Example 3: One more fix

  1. Mia changes one more thing, to five winds.
  2. The plane zooms over the fence!
  3. Changing one thing each time showed which change helped.

Example 4: Too many changes

  1. If Mia changed ten things at once, she could not tell which one helped.
  2. So she changes one thing, tries again, and looks.

Watch out

Try it

  1. The plane dropped near Bo. What does Mia do?
  2. How many things do we change at a time?
  3. Is it okay if the first try does not work?
  4. Which comes first: try the steps or see what happened?
Answers: 1. Looks at what happened and fixes one thing · 2. One · 3. Yes · 4. Try the steps
Try at homeFold a paper plane with a grown-up, fly it and see where it lands. Then change just one thing, like bending the wings up a little, and fly it again. Did that one change help? Try changing one more thing.
For grown-upsFold a paper plane together, fly it, and change just one thing, like bending the wings up a little. Then fly it again and ask: did that one change help?
