Valentine Science Experiment – My Fizzy Valentine

Valentine Preschool Science Experiments

To Make the Hearts

• 1 Heart shaped mold
• 1 cup Baking Soda
• 1 tablespoon Washable red paint
• 2-3 tablespoons water
• 1/2 cup vinegar
• 2 squirt bottles
• 1/2 cup of water with food coloring in it (any color)
• 2 small bowls

Grab a bowl and add the baking soda as well as the red paint. Then add 2 tablespoons of the water.  Mix. If the mixture is just right (easy to manipulate and not too wet) then disregard the last tablespoon of water.

Place the mixture in the silicone mold and let it dry overnight.

The following day, once the hearts are dry: 
When setting up your area, you will have two small bowls, food coloring, vinegar, your 1/2 cup of water and your hearts.

Place 2 hearts in each bowl and also place 1 condiment bottle beside each bowl.

Grab 1/2 cup of vinegar and place it in  one of the condiment bottles.
In the second bottle, add 2 drops of food colouring as well as the 1/2 cup of water. The purpose of adding the food coloring to the water is to make it distinguishable from the vinegar.

Ask your child to add the water (with the food coloring) to the hearts and ask them what is happening.
Next, add the vinegar to the other bowl and note your preschooler’s face. J just about screamed with glee when we saw what was happening.

Explain to your child that the hearts are fizzing because of the vinegar mixing with the baking soda. You can also discuss the differences in how the hearts reacted to the different liquids.

I would say this experiment was a win-win.

Thanks to Alecia, preschool blogger at Learning 2 Walk, for today’s experiment!   She had another fun idea: She took a few of the hearts and added it to her baby’s diaper bin.  The aroma from the diaper bin has SIGNIFICANTLY decreased and according to J, her daughter, his room no longer has an odor when his bin is opened.
