Your child picks something outdoors they are curious about, writes down a guess about what will happen, then checks the same spot over several days and records what they notice in a small notebook.

How to do it

  1. Go outside together and let your child pick one thing they want to find out about (a plant, a puddle, an ant trail, where the shade falls).
  2. Help them turn the curiosity into a question they can actually check, such as whether the puddle will still be there tomorrow.
  3. Ask them to write or draw their guess in the notebook first, helping with spelling if they want it.
  4. Over the next few days, visit the same spot together and let your child add a note or drawing about what they see each time.
  5. At the end, look back through the pages together and talk about how the guess compared with what really happened.

What you need

  • Notebook
  • Pencil

Signs it is working

Your child names something they want to find out and offers a guess, even a wild one. They come back to check their spot at least twice and add a mark or drawing each time. They notice out loud when the result matches or surprises their guess.

If it is not quite clicking

Child cannot think of a question: Offer two or three specific choices to pick from rather than asking them to invent one from nothing. Child loses steam before the days are up: Shrink the project to a single morning and afternoon comparison. Writing frustrates them: Let them draw the record or say it out loud while you write it down.

Make it yours

Younger, 5-6 years: You do the writing and they draw; keep it to one question checked one time. Older, 8-10 years: Add a second question, or have them note the weather each day and look for a connection. Siblings: Each child keeps their own page for the same shared spot.
