    If your kids are anything like mine, they love bubbles. Bubbles outdoors, bubbles in a bath, Bubble Guppies... You get the point. I knew my twins would enjoy this simple science experiment where they could combine vinegar and baking soda to make foam and BUBBLES! We have done Baking Soda Experiments before and they have always been a hit. Bonus: I already had all the items needed and I bet you do too. Let's have some fun with Chemical Reactions for Preschoolers.  

    These chemical reactions fore preschoolers will amaze and delight kids. Teach kids science concepts in a fun and hands on way.

    Chemical Reactions for Preschoolers

    Supplies:

    • Cup of Vinegar
    • Baking Soda
    • Clear glass or cup
    • Tablespoon

    *Please supervise your child during this activity.

    vinegar and baking soda

    The kids scooped a tablespoon of baking soda into a clear glass.  I would recommend a larger glass for this so you have more room for bubbles and fizzing.  Here is A dropping baking soda into her glass. I love that you can see the little cloud of dust above the glass.  See that look on her face?  That is the last time you will see my kids not smiling during this activity.

    See?  Here come the smiles. "A" just dumped a tablespoon of vinegar in her glass with the baking soda and was delighted to see the reaction that occurred.  Before she added the vinegar, I asked he what she thought might happen and she said "let's see."

    B was positively giddy as the vinegar combined with the baking soda.  The girls kept pouring the vinegar in tablespoon by tablespoon until I suggested we could see what happens if we pour a lot of vinegar in at  once.  "A" guessed that it would make "big bubbles."

    You can see the results!  We had a bit of an overflow.  But the smiles continued.

    My kids aren't old enough yet to understand the science behind this chemical reaction, but it sure made an impression on them.  We all enjoyed this simple science activity.  The kids loved the foam and bubbles, and I loved their reactions. I know this will be a big hit with your little one as well.

      That is SO fun! What a look of delight! I think bubbles still charm even adults. I like to blow bubbles outdoors in the winter, when we have really cold temps. The bubbles freeze and then pop very slowly. 🙂

      Vinegar and bicarb are such a winning combination.

      A while ago, we made a fantastic lava lamp mock up with them. We put coloured vinegar (food colouring) in the bottom of a (large jam-jar sized) clean jar, and topped it with vegetable oil - about half and half oil and vinegar. Your large glass would probably work for this too. Then we dropped in spoonfuls of bicarb. It was spectacular! and gorgeous. The bubbles rise up through the oil, taking the coloured vinegar with them, then they release the CO2 at the top and the coloured blobs sink back down again. One day I will blog it ;).
