Conduct physics, chemistry, and biology experiments with tools and ingredients found in any kitchen! These 52 labs created by mom and scientist Liz Lee Heinecke introduce fundamental scientific principles in a fun and accessible format.

Have fun:

  • exploring physics: marshmallow slingshots serve as a lesson on the transformation of energy and an egg-throwing experiment demonstrates the law of motion.
  • learning about microbiology by growing your own microbe zoo on a homemade petri plate. 
  • learning about rocket science by making and launching bottle rockets, using water and a bike pump.

Other great projects explore the exciting science of crystals, static electricity, acidification, and solar energy. The experiments can be used as individual projects, for parties, or as educational activities for groups. It's the perfect resource for Girl Scout Brownies looking to earn their Home Scientist badges! Many of the experiments are safe enough for children as young as toddlers and exciting enough for older kids, so families can discover the joy of science together.

The popular Lab for Kids series features a growing list of books that share hands-on activities and projects on a wide host of topics, including art, astronomy, clay, geology, math, and even how to create your own circus—all authored by established experts in their fields. Each lab contains a complete materials list, clear step-by-step photographs of the process, as well as finished samples. The labs can be used as singular projects or as part of a yearlong curriculum of experiential learning. The activities are open-ended, designed to be explored over and over, often with different results. Geared toward being taught or guided by adults, they are enriching for a range of ages and skill levels. Gain firsthand knowledge on your favorite topic with Lab for Kids.

Kitchen Science Lab for Kids: Tie-Dye Milk

You’ll be amazed as you watch the forces of surface tension at work in this colorful experiment.

Imagine that surface of liquids is a stretched elastic skin, like the surface of a balloon full of air. The scientific name for the way the “skin” of a liquid holds together is surface tension. When the skin of the liquid is broken by detergent, food coloring and milk move and swirl around in interesting patterns on the milk’s surface.

Step 1: Add enough milk to cover the bottom of the dish. The experiment works best with a thin layer of milk.

Step 2: In the small cup or bowl, mix together three teaspoons of water and one teaspoon of liquid dish detergent or liquid hand soap. Some detergents may work better than others.

Step 3: Put several drops of different colored food coloring into the milk. Space them out in the milk so you can see what happens when you break the surface tension.

Step 4: Dip a cotton swab into the dish-soap mixture and then touch the wet swab to the milk. Don’t stir! The detergent will break the surface tension of the milk and the food coloring will swirl around as if by magic.

Step 5: You can keep re-wetting your cotton swab with soapy water and touching it to the milk. Sometimes it works to touch the swab to the bottom of the plate and hold it there for a few seconds.
