Rockhound Abound Student Activity

All of us have, at one time or another, reached down to pick up a rock that has attracted us. Whether because of colour or shape, texture or pattern, rocks and minerals seem to call us towards them. There’s a good reason for this.

Beauty Beyond Skin Deep

Some say that beauty’s only skin-deep. But one veterinary surgeon and his team look beneath the surface…literally. Scott Echols says that we don’t actually know very much about the anatomy of animals because haven’t had a way to properly visualize it. But now, with the help of a new imaging technology called BriteVu, researchers have access to a trove of data on animal anatomy.

The Spangler Effect – Toothpick Table Tricks

On this episode of The Spangler Effect, Steve prepares for Thanksgiving dinner, and the only way to do that is by practicing some of his favorite science table tricks.

Your Amazing Molecular Machines – Veritasium

Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old – this is normal, in fact it’s called programmed cell death.

To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells.

And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start – the double helix molecule that we always talk about.

This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C.

How Did Dinosaurs Get So Huge?

Part of why we’re so fascinated with extinct dinosaurs it’s just hard for us to believe that animals that huge actually existed. And yet, they existed! From the Jurassic to the Cretaceous Periods, creatures as tall as a five-story building were shaking the Earth.
