This demonstration only uses a few kitchen items and requires very little set up and clean up time. It’s perfect for little scientist-artists who are always looking for new activities and wondering how they work.
Show the power of chemistry by tearing apart an aluminum soda can with little effort. Just score the inside of a soda can to break the plastic lining, add some copper(II) chloride and water, and sit back—chemistry will do the rest. The single replacement reaction of aluminum metal with copper(II) ions “ dissolves” the aluminum from the inside out. With only the paint on the outside of thecan holding it together, the can will rip apart with just a firm twist. Continue reading
Less than a tenth the size of an ant, a dust mite’s whole world is contained in the dusty film under a bed or in a forgotten corner. This realm is right under our noses, but from our perspective, the tiny specks of brilliant color blend together into a nondescript grey. What are these colorful microscopic particles? Michael Marder explores the science of dust. Continue reading
After a brief absence and early morning appearances, you can catch the International Space Station at night as it crosses the sky. Here are the best viewing times across Canada. Continue reading
From a tree to an orangutan to bacterium, the annual top 10 new species list has the newest stars of Earth’s biodiversity. Continue reading
As of 1989, mankind had successfully sent craft to every known planet in the solar system except one: Pluto. Located in an mysterious region called the Kuiper Belt, Pluto is a scientific goldmine, and could hold clues to the formation of our solar system. Alan Stern explains how NASA’s New Horizons mission is going to allow us to see Pluto for the first time. Lesson by Alan Stern, animation by Eoin Duffy. Continue reading
In this lab, you extract and isolate DNA from strawberries using simple, household ingredients.
You’ve probably learned or heard about DNA, but have you ever seen it? With the Strawberry DNA experiment, you’ll extract, isolate, and observe the DNA of a strawberry in a matter of minutes. It sounds impossible, but thanks to special characteristics of strawberries, it’s actually very possible… and simple. You don’t have to be a geneticist and you don’t need an electron microscope. It’s easy, fun, and all you need are some household materials.
