Let’s Discover: Full of Hot Air

  With this month’s Let’s Discover!, you will build a solar-powered airship to harness the blistering heat of the summer sun. You only need a few things for this experiment: three black (or dark-green) plastic garbage bags, scissors, tape and preferably some fine thread or fishing line.   Hot air balloons operate on the principle that warmer air rises over ...

Let’s Discover: Call & Answer

With summer just around the corner, it is well past time for some outdoor science from Let’s Discover. This week, you won’t need much at all: just patience, some binoculars (optional!) and most importantly, some sort of recording/playback device (a smartphone or a handheld recorder would work very well). Birds can be found all over the world, but how familiar ... Read More »

Let’s Discover: Rocket Science

This Spring we have a lot to look forward to, including the return of astronaut Chris Hadfield! In honour of our country’s most famous astronaut returning to Earth, we are celebrating everything astronomy and space during the month of May at the Discovery Centre. To celebrate the momentous occasion we give you balloon rockets! For balloon rockets, you will need ... Read More »

Let’s Discover: A Spring-ling of Salt

It is that time of year in Nova Scotia when winter finally begins to release us from its icy grip. Hopefully the ice covered driveways and sidewalks in the province are thawing, but if they aren’t, we have a way of giving them a final push! Many people are familiar with this experiment: combining ice with a little salt. You ... Read More »

Let’s Discover: The Crater Creator

On March 11, staff members from the Discovery Centre were on Discovery Channel’s Daily Planet show, demonstrating just what a crater looks like and how it works – the best part is that this is also an experiment you can try at home! All you need is space for a mess (as always), corn starch, cocoa and some “asteroids” and ... Read More »

Let’s Discover: Switchable Ink

  It’s time to make use of the winter weather we’ve had lately and use those chilly temperatures to get the most out of this month’s experiment! Let’s Discover by taking a fresh crack at the ever-popular (but usually tricky) invisible ink.   You will need a specific product to try this out: a Pilot Frixion Ball pen. While we ... Read More »

Let’s Discover: Science Sand

  This month we are going to make something very strange: a substance called hydrophobic sand – literally, sand that doesn’t like water. All you need is some sand (the more colourful the better), some Scotchgard, an oven, a cookie sheet and some aluminum foil. There’s lots of drying time in this one, so it will take up much of ...

Let’s Discover: Hooked on Velcro

Until you learn to tie your shoes, the very most common way to cinch them to your feet is Velcro. The way that Velcro fastens together is not immediately apparent, but is easy enough to figure out with a little experimentation. This is a great subject for trying out a scientific method of investigation. All you will need is some ... Read More »

Let’s Discover: Grow Away, Winter!

Winter is on its chilly way again, as our days shorten and the temperature dips. This is, ironically, a great time to start gardening! This month, we humbly suggest an experiment that will keep some green in your home even when the skies turn gray (and occasionally white). You will need: potting soil, herb seeds, potting containers of some kind ... Read More »

Let’s Discover: Spray It, Don’t Say It!

  On October 12th, Discovery Centre took part in a Canada-wide attempt at a new Guinness World Record for the largest practical science lesson held simultaneously at multiple venues. One of the components of that lesson on Bernoulli’s principle is a great one to try at home, so we present to you The Atomizer!   For this experiment, you will ... Read More »
