kids doing science experiments

Kitchen Science


Did you know that your kitchen is a science lab?  Well, it is!  I am going to introduce you to some family friendly science experiments that you can do together.  While conducting the experiments it’s important to remember “Hands on.  Minds on.”  Caregivers can have the children measure out the ingredients.  Be sure to ask the children what is happening and why.  If you don’t know the answer that’s okay, you can research it with the children together.

On July 29 Jenn will be debuting a prerecorded video on Kitchen Science.  If you wish to follow along these are the experiments being demonstrated and the ingredients needed for them.  Plus, at the end of the video you’ll hear the secret word for a Summer Reading Club badge!


This is the recipe I’m going to use:

Food colouring (optional)
Mixing spoon

The mixing ratio is simple:  one part water and  two parts cornstarch.  Place the cornstarch in the bowl and add the water slowly, play with the ratios.  What’s magically about goop is that it is both a solid and a liquid.  Goop is a non-newtonian fluid that changes from a liquid to a solid and back again when handled.

Rainbow Milk Science Experiment

This is the recipe I’m going to follow:

Whole Milk (3%)
Food colouring
Dish soap
Shallow dish

Pour a thin layer of milk into the dish.  Squeeze droplets of the food colouring on the milk.  Next, dip a Q-tip in the dish soap and then in the milk, preferably in the center of a spot of food coloring.  Watch the colors explode all over as the detergent interacts with the fat molecules in the whole milk!  In the link above you can find out in depth information on the “how” and “why” behind this experiment.

The Volcano-A Classic Science Experiment

For this experiment I am following:

Baking soda
Dish soap
Food colouring or washable paint (optional)
A pop bottle or a large cup 

Pour some baking powder into the bottle.  Then add in some vinegar.  Watch what happens next!  The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid which is very unstable, it instantly breaks apart into water and carbon dioxide, which creates all the fizzing as it escapes the solution.

Even more science experiments to do!
