Halloween Candy Fun with Science Experiments and Math Activities

Learn about water stratification by creating a rainbow with Skittles candy.

Water stratification is what happens when water displays different properties such as temperature, density, oxygenation and salinity. These layers act as barriers that prevent the water from mixing.  The food dye in the candy makes this process visible to us.

All you need for this experiment is:

  • Skittles

  • Water

  • Plates

You can find step by step instruction at: Little Bins for Little Hands.

Watch the rainbow magic unfold right in front of your eyes on this YouTube clip:


Learn about osmosis with this gummy bear experiment.

Osmosis is the movement of a solvent from one of lower concentration to higher concentration.

All you need are:

  • 2 small bowls

  • Water

  • Salt

  • Gummy bears

You will find step by step instructions at:

Learn about gummy bears and osmosis with this fun YouTube science rap titled:

"Let's talk about our gummy, in osmotic terms, Hypotonic, hypertonic, isotonic are the words You can use to discuss water's watery diffusion, Learn 'em well, to avoid confusion.”

Explore the relationship between sight and taste with a jelly bean taste test.

All you need is:

  • A packet of jelly beans

  • Colored markers to match the jelly beans

  • Water

  • Pen

  • Blindfold

You will find step by step instructions and the jelly bean taste testing record sheet at:  Childhood 101-Science For Kids


Keep Your Candy Cool With the Power of Evaporation!

In this experiment you will use the energy produced when water evaporates to cool down

chocolate-covered candy so it doesn't melt.

You will need:

  • Paper towel (6 sheets)

  • Scissors

  • Small bowl of room-temperature water

  • Chocolate candies in wrappers or small chocolate candy bars in wrappers

  • Tape

  • Ruler

  • Drinking glass

  • Hair dryer

  • Timer

  • Notebook

the CYBERCHASE episode that inspired this science fair project idea.


M&M Statistics!

In this mathematics science project, you will determine the frequency of different colored M&M's in a package of M&M candies.

For this project you will need:

  • Standard-size packages of plain M&M's (at least 5)

  • Colored pencils or markers

  • Lab notebook
