St. Patrick’s Day Science Experiments

There are TONS of adorable St. Patrick’s Day crafts out there (and if you don’t believe me, check out my Pinterest board), but sometimes my inquisitive kiddos are looking for a bit…more. And no, that doesn’t mean more “devil’s dandruff”…err…glitter. Instead, they are looking for St. Patrick’s Day activities that involve exploration and discovery. Yours too? Then try your hand at  St. Patrick’s Day Science Experiment so your family can celebrate in a fun and colorful way.

St. Patrick's Day Science Experiment - Chasing Rainbows

CHASING THE RAINBOW ST. PATRICK’S DAY SCIENCE EXPERIMENT

THE PURPOSE

In this St. Patrick’s Day Science Experiment, young scientists will learn all about absorption and how it changes based on aspects such as materials and time. Not only will the kiddos get their hands dirty while learning, but they will also end up with a bright and colorful craft to have on display for St. Patrick’s Day.

MATERIALS

  • 6 clear cups
  • Water
  • Vinegar
  • Food dye (red, orange, yellow, green, blue, purple)
  • Variety of paper towels
  • Paper and pencil
  • Clock

St. Patrick's Day Science Experiment - Absorption Study

WHAT TO DO

One of the best things about this rainbow filled science project is that you can make it as simple or thorough as you want. The most important thing is to fill the cups with the same amount of colored liquid and then connect the liquid inside the cups with paper towels so that the color absorption is noticeable. Easy peasy!

Step One: Fill each cup with the same amount of liquid.

Step Two: Put 3-4 drops of food coloring in each cup. Cup one is red, the next is orange, and so on using the rainbow for guidance.

Step Three: Roll up paper towels and put each end of the paper towel into the colorful liquid in adjoining cups.

Step Four: Wait until the paper towels begin to absorb the colorful water and become completely dyed so that the experiment yields a colorful, paper towel rainbow.

HOW TO STEP IT UP A NOTCH

Looking for a more in depth science project? Then start experimenting with different liquids. For example, compare how fast traditional water is absorbed as compared to vinegar. Does the temperature of the liquid make a difference?

Chat with your little scientists to see what other factors you can test. I mean, you can even pretend you are at a school science fair and test the absorbency of different brands of paper towels! (Yep, that was my science experiment in middle school…and I must admit that Brawny does have brute strength).

Lastly, be sure to focus on how important TIME is to absorbency. Set a timer to remind yourself to check on the paper towels after 15 minutes, 1 hour, 3 hours, etc. My kids and I discovered that after 48 hours, the paper towels were so saturated that they simply couldn’t absorb anymore…and that once we dried them, the paper towels made GORGEOUS artwork.

St. Patrick's Day Science Experiment - Sugar Dissolution

SKITTLES PAINT THE RAINBOW ST. PATRICK’S DAY SCIENCE EXPERIMENT

THE PURPOSE

In this St. Patrick’s Day Science Experiment, young scientists will learn all about dissolution and dispersion and how it changes based on aspects such as materials and time. While your kids might think the best part of the experiment is snagging a candy or two, their real enjoyment will come from the unique and colorful patterns they make by simply combining Skittles and water.

 

MATERIALS

  • A white plate, preferrably with a rim to keep water from dripping off the plate
  • Skittles
  • Warm water

St. Patrick's Day Science Experiment - Skittles

WHAT TO DO

One of the best things about this rainbow filled science project is that there are no wrong ways to do it. Simply arrange the Skittles in any pattern you want on a white plate. If you want a more colorful result, place the Skittles next to each other. If you want more white space, leave room between the colorful candies.

Step One: Arrange Skittles in any pattern you want on a white, rimmed plate.

Step Two: Once you have the Skittles arranged, slowly pour 1/2 cup of warm water over the Skittles. If you want the colors to disperse quickly, use more water. Use less water if you want the colors to spread more slowly.

Step Three: Sit back and watch the show! The warm water makes the colorful, sugary coating dissolve and the colors then disperse in patterns along the plate.

Looking for a more in depth science project? Then start experimenting with different liquids and different liquid temperatures. Test out other sugar-coated candies and see if they hold up as well as the Skittles do.

    What an awesome craft for St. Patrick’s Day. I love that it uses items we have around the house and that it’s easy enough that even the younger kids can get in on the fun.
