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

Love this! What a fun way to discuss absorption!
Thanks, I’m glad you like it!
This is so clever. I love the element of play in it. Will try it with my daughter as well!
Thanks Natalie xx
I must remember to dig out the lego later! Love it! Popping over from the Parenting Pin It Party !
Thanks, let me know if you try it!

Such a fun and easy way to learn about materials and absorption! The addition of the Lego men makes it even more special.
I’m glad you like it Trisha!
Super cute! My son would love this
Let us know if you try it!
So many of your ideas are going on our list of things to try in the summer holidays! xx
Do let us know how you get on 🙂
I can’t wait to do this with my boys! I’m sharing this tomorrow at the After School Linky Party; stop by to check it out and share more of your ideas and activities!
Thank you x
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!
