by Carol Saab, 8 August 2013 | 3 comments

DNA is the blueprint and genetic guide for every living thing, and units of DNA are tiny. So how can we see it with our own eyes? Many DNA units form a long, stringy molecule that is easily visible and easy to extract from particular living things, like peas or a banana.

How does an optical illusion work? Activity

by Carol Saab, 20 June 2013 | 8 comments

Our eyes play a huge part in helping us explore the world around us, but occasionally they play tricks on us. In this optical illusion, we’re testing your perception of colour by making an after-image optical illusion. In other words, we’re tricking your eyes to see colours that aren’t really there. Check it out!
