Think with your hands! Spark's Take it Apart table in the Open Studio Gallery is a visitor favourite allowing guests to build real skills using real tools. Go on a behind-the-scenes tour of this exhibit with Davis!

DIY Liquid Rainbow

Dates: April 20 |

Making a liquid rainbow using density and solubility!


  • Food colouring
  • Salt (sugar is a great substitute!)
  • Mixing Containers
  • Syringe or Turkey Baster
  • Water

INQUIRY QUESTIONS: What would happen if you made two colours have equal density? Would the colours blend together over time?

Grow from Plant Clippings

Dates: April 17 |

Spark's robotic garden, FARMBOT, is home to many delicious herbs and plants. Davis is back with tips and tricks on how to grow more basil from a clipping straight from the science centre.

DIY Egg Geodes

Dates: April 13 |

Home-grown tomatoes need a boost? EGGSHELLS. Stubborn dirty pans? EGGSHELLS. White linen sheets looking a little dull? EGGSHELLS.

What might be trash to one, is treasure to another! Explore new ways of experimenting with eggshells in today's Egg Geode science experiment! Turn an eggshell into a beautiful crystallized home project.

What makes us human?

Dates: April 6, 2020 |

What makes us human?

Davis explores what connects us and makes us human through Spark's Being Human gallery.

At times like this, it's especially important for us to stay connected even at a distance. If you or someone you love is struggling with mental health, feel free to use the resources provided by the federal or provincial government including the tips below:

Alberta Health Services mental health helpline: 1-877-303-2642

Kids Help Phone is available to kids and teens in need of someone to talk to, no matter what: 1-800-668-6868

Waves and Puddles

Dates: April 3, 2020 |

Ever wondered where waves come from and how are they formed? Davis is taking a closer look at ripples + waves near or in your home.

Try this science observation in your bathroom or a melted puddle on a warmer day.

Fire + Water Balloons

Dates: March 31, 2020 |

Let's get POPPIN' with a special fan request from two tiny Sparkians - the classic convection and hydrogen balloons science demos!

1. Can you pop a water balloon with fire? 
2. What happens when you fill a balloon with hydrogen gas? 

DIY Milk Plastic

Dates: March 29, 2020 |

Try out this simple legen-dairy science with staple items in your own kitchen with a good ol' cuppa milk and white vinegar. Milk has a protein called CASEIN that's not soluble with acids, like vinegar – a common household ingredient. When mixed, you'll see an instant reaction separating the water content with long molecules and curdles that can be molded and shaped when cooled. 


1 cup milk
1 tbs vinegar


Will other acids like lemon juice work?
What would happen if you tried soy milk instead? 

Sneeze the Day!

Dates: March 27, 2020 |

Sneeze the day with a bit of science! So what actually happens when you sneeze? 

A sneeze acts like a reset button. There are these things inside your nose called cilia that detects foreign substances and sends a signal to your brain! When you sneeze, you clear your nose and nasal cavity of things like dust, pollen, smoke, and even pepper!

DIY CO2 Fire Extinguisher

Dates: March 26, 2020 |

Get your science gear and head to the kitchen! It's time for this classic at-home science experiment. Davis the chemist is brewing up an invisible fire extinguisher straight from his home laboratory - the kitchen! 


Baking Soda
Candle flame


Is carbon dioxide heavier than air?
How many flames can you extinguish with a cup of baking soda and vinegar?

Science Behind Fire

Dates: March 25, 2020 |

The Fire Triangle

Combustion reactions ignite when all three things are present: 

1. Fuel Source (ex. wood, paper, gasoline)
2. Heat Source
3. Oxygen 

If one of these items is missing, the fire triangle will be incomplete. Have you ever tried drawing a triangle with only two sides? Challenge accepted! 

*Please do not try this at home 

Science Behind Bed of Nails

Dates: March 24, 2020 |

Spark is bringing science to you!

Take the pressure off by lying on a bed of 1000 nails! Learn the science behind one of Spark's beloved exhibit, the Bed of Nails. 

Pressure is created when two things come in contact with one another. With an even distribution over a large surface area such as a bed, the weight of your body is distributed across many contact points.

While families practice social distancing, we know how important it is to stay connected to the world around us.
To recognize UN World Water Day (Mar 22), why not explore the backyard or your neighbourhood to discover, sample, and talk about the water all around us? 

Grab some containers, label them, bring spoons, miniature shovers, cups - or anything in the Tupperware cupboard - and get outside!


  • Tupperware containers
  • Labels 
  • Markers
  • Water around you! (Ice, snow, etc...) 


  • Why is it important to be protectors of water?
  • How much does water play a role in our daily lives?
  • What differences do you notice about different forms of water?
