STEM Experiments with ‘Mommy and Me: The Listers’

HOUSTON (KIAH) – They may possibly be minimal but they are fierce! Specifically when it comes to STEM activities and training. We’re talking about 2-yr-aged Krissy Lister and her 1 yr-old sister, Kinsley Lister.

Their mother Crystal Lister has started out a YouTube channel, Mommy and Me: The Listers. Its an interactive and instructional avenue wherever Crystal shares her passion and expertise for teaching STEM education by her two very small co-stars. 

They join Houston Comes about host Maggie Flecknoe to share 3 of their favored experiments. You can participate at residence! See underneath for far more on each and every experiment. 

Experiment #1

“The Magic Milk” for ages 3 and up


  • Plate
  • Q-Tip
  • 2-ounce cup
  • Milk
  • Dish Soap
  • Foods coloring


  1. Pour the milk on the plate
  2. Include drops of foods coloring to the milk in the plate, be confident to space the drops out
  3. Dip the Q-idea in the cup with the dish cleaning soap then
  4. Dip the Q-suggestion with soap on it in the plate with the milk and the foods coloring and watch magic transpire!

Science powering it:

The extra fat in the milk reacts with the dish cleaning soap triggering the molecules to go all over. This is why entire milk will react much better than a very low fat, or a 2% milk would.

Experiment #2 –

“Elephant Toothpaste” or that we renamed Elephant Soap for ages 3 and up*

Adult supervision required


  • Security Gear (gloves, goggles, apron or lab coat)
  • 3% hydrogen peroxide or 30% Hydrogen Peroxide for the greatest response (adult supervision with managing necessary)
  • 1 packet of Active Yeast or 1 spoonful of Potassium Iodide for greatest reaction
  • Food items Coloring
  • Erlenmeyer flask
  • Beaker
  • Stirrer
  • Measuring Cup
  • Water


In this video clip, we are real scientists and conduct the experiment with different ingredients to see which will make the largest and foamiest Elephant Soap! We switch the yeast with potassium iodide and 3% hydrogen peroxide with 35% hydrogen peroxide for a more substantial response but, be careful and question an grownup prior to use or managing.


  1. Pour 50 percent a cup of 30% hydrogen peroxide in flask
  2. Incorporate a handful of drops of foodstuff coloring and a squirt of dish cleaning soap to the peroxide in the flask
  3. In a individual beaker mix a spoonful of potassium oxide into 2 tablespoons of h2o
  4. Stir until eventually crystals have dissolved earning a resolution
  5. Pour Potassium Oxide solution into the flask with the peroxide
  6. Action Again
  7. Check out the chemical response create the Elephant Cleaning soap

Science at the rear of it:

In this entertaining foamy experiment, it demonstrates a chemical reaction where the foam is oxygen-loaded bubbles that end result from the hydrogen peroxide being damaged down into h2o and oxygen. This response makes use of either yeast or potassium oxide as a catalyst to velocity up the reaction.

Experiment #3

“Sink or Float” or Relative Density for ages 3 and up*



  1. Fill your bin up with water
  2. Toss products in the bin of water
  3. Observe if it will sink or float

Science powering it:

In this moist experiment, Krissy and Kinsley take a look at out distinct household objects to see if they are a lot more dense and will sink or much less dense and will float in drinking water.
