Here is a great St. Patrick’s Day activity to do with kids to learn about chemistry! The supplies are really simple – just baking soda, water, and vinegar. You can also add some food colouring and fun little treasures. They are so easy to make and kids love them! I created these as a science experiment for my kids to do on St. Patrick’s Day.
Since I teach kindergarten, I have to be careful what materials I use when I do science experiments. I love doing this experiment because it is safe for young kids, but still really exciting and a great learning opportunity.
Start by adding baking soda to a bowl and then adding water. You want the mixture to be roughly the consistency of cupcake batter. If it is wetter, it will still work, it just takes longer to dry. I then added a few drops of green food colouring.
I used a silicone muffin pan to create my baking soda pucks. First, I added some treasures for my kids to find – I used glass stones, shamrock cutouts and plastic coins.
I added my baking soda mixture to the pans and a few more treasures on top. (I added extra food colouring to darken some of my pucks).
Leave the pan on a flat surface to dry over night. When dry, they will simply pop out of the muffin pans!
Once the pucks are dry, you are ready to do your science experiment! I like to use eye droppers, but pipettes or medicine droppers work just as well. Have kids drip vinegar onto the baking soda puck and watch for the fizzy chemical reaction!
It is very exciting when the fizzy bubbles clear and kids begin to see all of the treasures inside. It is fun to watch them work like scientists to discover all of the hidden St. Patrick’s day treats.
