WHAT CAN DISSOLVE IN WATER?
LIQUID SOLUTIONS AND FUN CHEMISTRY FOR KIDS!
I always recommend adult supervision when it comes to picking out supplies and sometimes handling supplies! Adults please use your best judgement in regards to suitability of each science experiment. You can adapt if necessary to fit your kids needs and abilities.
WHAT ARE KID’S CHEMISTRY EXPERIMENTS ALL ABOUT?
Let’s keep it basic for our younger or junior scientists! Chemistry is all about the way different materials are put together, and how they are made up including atoms and molecules. It’s also how these materials act under different conditions and go through changes. Chemistry is a base for physics, so you will see overlap!
What might you experiment with in chemistry? Classically we think of a mad scientist and lots of bubbling beakers, and yes there are reactions between common acids and bases to enjoy! Also, chemistry involves matter, changes, solutions, and the list goes on and on.
We will be exploring simple chemistry you can do at home or in the classroom that isn’t too crazy, but is still lots of fun for kids! You can check out some more chemistry activities here.
WHY IS KIDS SCIENCE SO IMPORTANT?
Kids are curious and always looking to explore, discover, check out, and experiment to find out why things do what they do, move like they move, or change like they change! Indoors or outdoors, science is amazing!
Science surrounds us, inside and out. Kids love checking things out with magnifying glasses, creating chemical reactions with kitchen ingredients, and of course exploring stored energy! They have a lot of that! Check out 35+ awesome science projects to get started.
There are lots of easy science concepts that you can introduce kids to very early on! You might not even think about science when your toddler pushes a card down a ramp, plays in front of the mirror, laughs at your shadow puppets, or bounces balls over and over again. See where I am going with this list! What else can you add if you stop to think about it?
Science starts early, and you can be a part of that with setting up science at home with everyday materials. Or you can bring easy science to a group of kids! We find a ton of value in cheap science activities and experiments. Check out our homemade science kit.
WHICH SOLIDS DISSOLVE IN WATER?
Our simple chemistry experiment today is all about solutions and which solids dissolve in water!
Let’s get set up and gather our supplies. We also have a free printable page you will find at the bottom for download. Also below, you can read the science behind this mixing solutions science experiment.
Make sure to include a few talking points with your kids, so they can make predictions for each of the solids you or they have chosen! What do they think will happen? Have them write out a hypothesis if desired. Read more about how to use the scientific method with young kids.
You can also go over some simple vocabulary including a solute which is the material to be dissolved and the solvent which is the liquid used to test the solute. In our case the solutes are the materials listed below and the solvent is water! READ MORE SCIENCE BELOW

HOW TO SET UP DISSOLVING SOLIDS EXPERIMENT
Now that you have your predictions, you are ready to find out the results. Let’s set up the chemistry experiment! Adult supervision is suggested.
First you want to heat the water so it is warm, that makes the experiment happen a bit faster. (Another interesting method is to try the experiment with cold water and note the differences.)
Let your kids choose which solids they want to try to dissolve, it doesn’t have to be what we used. This is what makes it awesome kitchen science because it’s all about what you have in your kitchen!
Make sure to ask your kids which solids dissolve in water! See what they think. It doesn’t have to be correct. If there answer is initially wrong, let the find out by experimenting instead of you correcting them!
FUN FACT: Long ago, alchemists tried to turn substances into gold (unsuccessfully I might add) but they pioneered the idea of experimenting and testing for us! Let your kids be modern day alchemists with this testing solutions chemistry experiment!
Once you have discussed your ideas, add a tablespoon of each material to a jar.
Next, pour 1 cup of warm water into each jar. A good scientist carefully measures so that all variables but one are the same.
Lastly, you want to give each jar a stir and then wait 60 seconds. I love having a kid friendly stop watch on hand for these activities.
Once the time is up, your kids can determine which materials dissolved in the water and which didn’t. Were they correct? Did they need to change their answers?
What do your results show you? Can you pick out which are homogenous mixtures? Read more about solutions below!
WHATS THE CHEMISTRY BEHIND THIS EXPERIMENT: WHICH SOLIDS DISSOLVE IN WATER?
It might just seem like you are making a bit of a mess, but you are actually experimenting with an important concept in chemistry called solutions. By mixing these solids (solutes) with a liquid (solvent), you may or may not have created solutions.
What is a solution (or you might also hear it called a mixture)? A solution is when one substance (our solid) is dissolved in another substance (the water) with an even consistency. This is called a homogeneous mixture. We also do this when we experiment with CRYSTAL GROWING!
You can mix in two or more substances but for our experiment we are just mixing one solute and the one solvent together. Generally the solute is smaller in quantity then the solvent. What would happen if it were the other way around?
