Baking soda experiments

It is fun when STEM can coincide with holidays or other exciting themes. Science is fun on its own but when you add in a fun theme, it’s even better. For this frozen Valentines Day activity, you’ll need: 

  • Baking Soda
  • Water
  • Food Coloring
  • Glitter or conersation hearts
  • Cookie Cutters, or molds
  • Vinegar
  • A baking dish
  • 2 bowls for mixing 

Baking soda experiments

Valentines Day Activities for Kids

Start this experiments with baking soda by coloring about a cup of water. We used red food coloring and mixed it together.

Next pour about a cup of baking soda in a bowl. Add in about a TBS at a time of the colored water and mix as you go. You want the consistency to be moldable. If you put a scoop in your hand and squeeze, it will hold its shape. If it is too watery, it will not work correctly.

Once the baking soda is mixed all the way, put the cookie cutters on a plate. Fill the cookie cutters half way with the baking soda mixture, and press in. Next add a layer of glitter. We used red. Then fill the rest of the cookie cutter with the baking soda mixture and press down. This should cover the glitter completely.

Put these into the freezer. We kept them in the freezer for about two hours.

When you’re ready to experiment, take the baking soda hearts out of the freezer and pop them out of the cookie cutters. We had a hard time getting them out, so we ran a tiny bit of vinegar around the edges and they popped right out. Water may have worked too, but we tried vinegar.

Place the frozen hearts on a plate and grab your vinegar.

We put the vinegar in squirt bottles to start, but ended up pouring out of the jug. Each way worked equally well.

We did little squirts at first to watch the bubble reaction, but when we became impatient for the big show, we poured more vinegar over the top. The hearts would start to melt and the glitter started dancing around.
