Hidden LEGO Men – 100 days of play

Welcome to the 100 Days of Play Blog Hop, hosted by SunScholars and Life at the Zoo. Together with lots of other bloggers, 100 days of wonderful and inspiring play ideas are being posted.

Today is the turn of Science Sparks and we’ve been finding out what happens when paper gets wet.

What you need:

  • Different types of paper cut into squares, we used a thin paper, thicker notebook paper and cardboard.
  • Some LEGO men or other small toys.
  • Water



  • Fold each corner of the paper into a triangle to it looks like the below.



  • Place a Legoman inside each folded paper and place them all on the water at the same time.
  • Sit back and watch as each man is revealed.

Before we started we felt each piece of paper and talked about which we though would absorb water the easiest, Z thought the thinner paper would absorb more water faster than the cardboard.



The Science Bit


Paper is made of lots of fibres, as they absorb the water they swell and the paper expands, which made the triangles open up.


Different types of paper absorb water at different speeds. Thinner paper absorbs more quickly, as it has thinner fibres.

    Great idea! I loved playing with LEGOs in the water, but this will add a lesson to it as well. And then you can have the LEGO coast guard come to rescue the guys after the experiment is done!
