Recently I saw this idea for a pre-schooler science experiment and I thought Snow White would enjoy giving it a go.
She was very excited when she saw me setting up the tray and kept asking me what it was and could she play with it now? I put out some things from the kitchen cupboards and wrote labels then asked her to tell me which substance was which. She didn’t know coconut, but was quickly able to work it out by a process of elimination.
Spooning and stirring was a big hit!
Her idea of predicting whether each substance would dissolve was to always say “yes”, but that’s OK. We decided at the end that only the sugar had really dissolved. The flour seemed like it might have done, but then she could see it settled at the bottom once the water had stopped moving. An extra test for the sugar having dissolved was tasting the sweetened water 
After the structured part of the experiment, I took the water away and let Snow White play with the spoons and bowls of things. Her first move was to plunge her hands into everything, whereupon she proceeded to tell me what they all felt like. Rice was “smooth”, flour “soft”, coconut “prickly” and sugar “hard”. I was quite impressed at her doing this without me asking her what they felt like. I think maybe she has been encouraged to do this sort of thing at pre-school.
After that she scooped everything in to one bowl, mixed it up and started telling stories about how the bowls were nests for birds with food in, and later burying the spoons in flour and telling me she was putting blankets on them so they could go to sleep.
The next day “exciting things” were demanded, meaning a repeat of this experiment, so it was definitely a success!
