STEM Experiment - Making Rainbow in a Tube

STEM Experiment - Making Rainbow in a Tube

Objective:

Demonstrate the concept of density and color mixing through the creation of a rainbow in a tube.

Ingredients:

  • 5 transparent tubes or glasses
  • 5 different types of liquids with varying densities (e.g., honey, dish soap, water, oil, rubbing alcohol)
  • Food coloring (red, blue, green, yellow)
  • 5 droppers or small spoons

Instructions:

  1. Arrange your tubes or glasses on a flat surface.
  2. Assign each liquid a different color using the food coloring (for water, you can leave it transparent or choose a color).
  3. Start with the densest liquid (honey) at the bottom. Pour this into the first tube until it’s about a fifth full.
  4. Take the next densest liquid (dish soap), and carefully pour or spoon it down the side of the container to form a new layer above the honey. Do this very slowly to prevent the layers from mixing.
  5. Repeat the process with the remaining liquids in order of density.
  6. Ensure each liquid forms a distinct layer above the previous one.
  7. Observe the colors forming a beautiful rainbow in a tube as a result of density variation.

Discussion:

After completing the experiment, discuss with your child about the different densities and how liquids with high density stay at the bottom while the ones with low density float on top. You can also talk about the color mixing and how it creates a rainbow effect.

Enjoy this colorful density experiment!


D.I.Y. Stethoscope STEM Experiment

With this fun and hands-on STEM experiment, discover the science behind how a stethoscope works. You can also have a go at creating your own stethoscope and then compare its efficiency with a professional one.

Materials Needed:

  • Two funnels (same size)
  • Clear vinyl tubing (about 2.5 feet long)
  • Duct tape
  • Balloons (2)
  • Scissors

Instructions:

Step 1: Preparing the Funnels

Take the funnels and place them at each end of the clear vinyl tubing to make a Y shape. Using your duct tape, secure the funnels to the tubing to ensure no air can escape.

Step 2: Making the Diaphragm

Cut off the end of one of the balloons to create a thin, flat piece of rubber. Strech this rubber piece over one of the funnels, pulling it as tightly as possible without tearing it. Fix the rubber piece in place with more duct tape, making sure it is entirely air-tight. This will serve as your diaphragm, an essential part of a stethoscope.

Step 3: Creating the Earpiece

Cut two smaller pieces from the second balloon and stretch them over the open and thinner point of the second funnel. Tape these in place. These will act as your earpieces.

Step 4: Testing Your Stethoscope

We now have a homemade stethoscope! Place the diaphragm (the flat end covered with the balloon piece) over your heart and listen through the earpieces. Can you hear your heartbeat?

Ensure supervision while the children are using the scissors.
