Science + Kids!

Science + kids is a perfect equation in my mind! When the scissors aren’t cutting it anymore (no pun intended) and the glue is just no longer cool, we turn to a fun and easy kid-friendly science experiment. There are so many neat ideas on the internet but I tend to gravitate toward the quick (15mins or less) ones. After all, when you have a 2 year old you have to be quick to keep his attention! I also lean toward ideas that require common ingredients/items and not things I have to go buy in order to do the experiment.

Mess is generally not an issue for me though because I’m mostly concerned with creating fun for the boys! I don’t focus too much on the scientific aspects of the experiment as we’re doing it but I hear my 7 year old using the key terms so that lets me know he is learning as we “play.” My 2 year old, if nothing else, is having fun sensory play and when he comes across these concepts in school he will have some prior knowledge!

Baking Soda and Vinegar — Two Basic Household Items, Two Great Experiments!


Blowing Up A Balloon 

One snowy day we grabbed:


700ml drink bottle


Baking soda 


I believe I had originally seen this idea on a Bill Nye the Science Guy video, so the measurements are approximations. (You can play with the quantities depending on the size of the bottle and the size of the balloon, anyway.)

Place about ¼ cup of vinegar in the bottle and 2 tablespoons of baking soda into the balloon. (*TIP: Have the kids take turns stretching the mouth of the balloon while you are getting things ready. This stretching will make putting the baking soda in the balloon a bit easier.)

Once the bottle and balloon are ready to go, stretch the mouth of the balloon and place it over the opening of the balloon. Be careful NOT to dump the baking soda into the bottle YET!

Once the balloon is securely on the bottle, have your child tip up the balloon and allow the baking soda to mix into the vinegar. Then, watch the magic! The balloon will blow up before their eyes.

We had to do this twice – each boy needed to have his turn dumping the baking soda into the vinegar, after all!

Baking Soda Volcano ~ Old Faithful Childhood Experiment

Last summer, as you can tell by the pictures, we did the old faithful baking soda volcano. We grabbed a piece of Bristol Board and made a cone shape with a quarter-sized hole at the top. During LittleL’s nap time one day, BigB painted the volcano to make sure it looked authentic! The next day we grabbed our supplies and headed outside. Using a 500ml juice bottle we poured vinegar and red food colouring into the bottle and placed our volcano replica on top. Once the volcano shape was in place we dumped a LARGE amount of baking soda into the bottle. Ta Dah! The boys loved the “explosion” of red food colouring and the volcano replica really added to the fun!


So, grab some baking soda and vinegar to have some fun and make a mess!
