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.

What might you experiment with in chemistry? You might think of a mad scientist and lots of bubbling beakers, and yes there are cool fizzing experiments to enjoy! However chemistry also involves matter, changes, solutions, and the list goes on and on.

Here you 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 more easy chemistry experiments here.


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!

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.

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

Give each mixture a stir to discover which solids dissolve in water


Our simple chemistry experiment today is all about solutions and what solids dissolve in water!

I always recommend adult supervision when it comes to picking out supplies and sometimes handling supplies! Adults, please use your best judgment in regards to the suitability of each science experiment. You can adapt if necessary to fit your kids’ needs and abilities.


  • 5 different powders such as Sugar, Salt, Gelatin Powder, Flour, and Pepper. What else can you find to use?
  • 5 clear jars
  • Water
  • Stirrers
  • Data Sheet (optional)

To discover which liquids dissolve in water add different solids from your kitchen pantry to test!


STEP 1. Start by talking about what you think will happen when you add water to your jars.

STEP 2. Then you want to heat the water so it is warm. This makes the experiment happen a bit faster.  (Alternatively, try the experiment with cold water and  then warm water, and note the differences.)

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 simple chemistry experiment!

STEP 3. Add one tablespoon of each material to each jar.

STEP 4. Next, pour 1 cup of warm water into each jar. A good scientist carefully measures so that all variables but one are the same. In this case, the amount of water is the same but the material in each jar is different.

Adding warm water to discover which solids dissolve in water helps to speed up the experiment a bit!

STEP 5. Lastly, you want to give each jar a stir and then wait 60 seconds. I love having a kid-friendly stopwatch 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?

Which solids dissolve in water and make homogenous mixtures?

What do your results show you? Can you pick out which ones are homogeneous mixtures? Read more about solutions below!

Can you guess which solids dissolve in water and which do not?


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 growing crystals.

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 than the solvent. What would happen if it were the other way around?
