How to make Art from Slime
We all know that playing with slime is one of the best things in the world. But, what do you do when you’re done. You can put it into a zip-lock bag and save it for later, or you can make Slime Art. What exactly is Slime Art? Well, once you leave slime out to dry it will turn into an amazing piece or sculpture.
Flame-retardant chemicals can slow the spread of fire in homes and garments. But are these compounds naughty or nice? This week on Reactions, we ask whether old Saint Nick might want a flame-retardant suit…or choose to opt out. Continue reading
Human brains are complicated – the most complicated thing in the known universe, many people say. So far we understand little – just that certain regions of the brain appear to be involved in certain activities and certain disorders. Continue reading
Fish living in the oceans around Antarctica seem like they should freeze to death. But notothenioids have it all figured out, thanks to the antifreeze proteins in their blood! Continue reading
Add a drop of clear solution to a microscope slide containing a tiny piece of copper and create a beautiful, silver-branched holiday tree that grows before your very eyes! Continue reading
Here’s a twist on the classic chemical hand warmers you can buy for you to research and improve.
If you’ve been outdoors when it’s really cold, there’s a good chance you’ve either used these yourself or wished you had. You can experience a variation on the science found inside a commercial warmer with some pretty basic materials. You’ll discover how an everyday chemical reaction like rusting is used to keep your digits toasty. This experimental version of the hand warmer is offered as a test idea and not as a definitive solution. You’re encouraged to share your science fair results online.
The kilogram, mole, kelvin, and ampere will be redefined by physical constants. Continue reading
