5 Completely Frugal Science Experiments

This year you can have fun and teach your kids great things with these 5 Frugal Science Experiments. Each of these has simple instructions and requires only a bit of imagination and a few pantry items you already have on hand.  Science is everywhere in our homes, it doesn’t have to break the bank… we just have to look for it!

5 Totally frugal Science Experiments for Kids

5 Frugal Homeschool Science Projects

Clean Mud Expanding Soap Recipe

Microwave Soap Snow:  One of our favorite things to do in our science class is to watch how simple substances can change with the right environment.  A bar of ivory soap placed on a microwave safe dish and heated in 15 second increments turns from a solid mass into a big puffy white ball of snowy soap.  This is a great way to talk about how molecule change shape depending on temperature, exposure to chemicals and other various elements.

How to change flower color experiment

Dye plants.  A fun and beautiful frugal homeschool science project is to grab a few flowers (preferably white) and place them in individual glasses.  Add a few drops of different food coloring to each glass, and watch as over the course of 24-48 hours they absorb not only the water, but the color in the water.  Your white flower will turn into a purple, pink, blue or yellow flower!

Fizzing Science Experiments with Baking soda

Baking Soda & Vinegar Volcano:  This one is a classic that is still relevant today.  Pour baking soda in a tall glass, then top with vinegar.  Watch as the baking soda begins bubbling out like a volcano.  These two substances combined make carbon dioxide turn to gas creating a bubbling effect that helps push the combination over the top of the glass (or paper mache volcano) like lava.

Mentos Geysers

Diet Soda & Mentos Explosion:  Much like the combination above, it has been found that a diet soda combined with the Mentos candy will indeed explode.  Get a 2-liter bottle of diet soda, a package of Mentos and go outside where the sticky mess won’t hurt anything.  Open the soda and pour in the package of candy.  The explosive soda fountain will begin right away.

Exploring Viscosity with Sensory Bottles

Liquids That Don’t Mix:  A great experiment that uses just a few things in your kitchen, is to how how some liquids won’t mix.  A little food coloring and specific liquids combined will make a beautiful layered glass of color. You’ll need honey, dish washing liquid, vegetable oil, water and rubbing alcohol.  Grab a few cups to mix each of these with food coloring if desired. You will use ¼ cup of each liquid.

  • Pour honey in first being careful to avoid sides of the glass
  • Tips the glass slightly and pour dish washing liquid down the side of glass.
  • Next pour in water, then oil, then rubbing alcohol using the tilted glass method to keep them going in slowly and evenly. The result should be a mostly separated layer of liquids.
