Science experiment on which solids dissolve in water

Both smarties love science. Especially the brother who loves reading all things about science. He loves reading Young Scientists and he will share what he learns with us and his little sister.

In order to allow him to apply  and to understand better what he learns, we do experiment in real life. Today, we did an experiment on what solids dissolve in water. It’s a very simple  experiment using simple tools but it can get the kids really fascinated.

Here’s what you need:
– mini funnel with a stand
– 3 small cups
– a stirrer
– sand, salt (powdered form and crystallised form), sugar, coffee powder (whatever substances you can find that can be used)

As we are only using plastic cup, therefore we only tested with tap water. We started the test by pouring the first pack of substance into the 2 cups provided.

Gor gor stirred one of the cups while the other one left unstirred. Then he observed the substance in the 2 cups.

Next, he poured the contents into the funnel and watched the flow of the liquid.

There were some undissolved particles left in the funnel and he tried to “break” it into smaller pieces so that it will be able to go through.

He wrote down his observations on his book and proceeded on to the next substance/solid.

The experiment was fun and engaging. Mei mei saw how her brother “played” with it and she wanted to get involved too! Here she is stirring and ….


The science bit of this experiment, the smarties get to learn:
– which solid is soluble (dissolve in water) and which is not
– how fast does it dissolve when they stir it
– how the size of the grain affects the speed at which it dissolve

On top of that:
– for younger children, they get to enhance their motor skills by stirring and pouring
– for older children, they get to practice on their writing skills

Go on and get experimenting!



I am a busy mummy of 2 wonderful kids. Their thirst for learning has made me busy researching and making learning resources/materials for them. Most of the time will be according to the topics that they have requested. Otherwise, I will randomly pick a topic and create the materials for them. Most of the time, the materials will include right brain training as well. From them, I get to learn a lot too! However, material preparation is quite a challenge! It will even be more challenging if you are a working parent! Here, I would love to share what we have done and hope busy parents out there will find our materials useful for their little one. If you have any queries/comments or if you have any topics that you would like to cover with your little one(s), do drop me a message and I will get back to you as soon as I can :) Our mission is to find, discover and reveal the fun of kids learning! Drop us a message if you are interested in any of our materials. Let's make learning fun!
