SCI CODE: Why Does Salt Melt Ice?
Imagine that you are an H2O molecule. As a liquid, you vibrate and flow around with other water molecules. When temperatures get low, you vibrate less and begin connect with your neighbors to form ice.
BUT THEN ALL OF A SUDDEN NaCl GETS IN YOUR WAY!
With salt all up in your space, it becomes more difficult to bond your fellow H2O’s. That’s what’s happening when you melt ice with salt.
Most people will just say that salt lowers the freezing point of water. That is true, but it’s not the whole story.
Black Hole Rap 2: Stephen Hawking Said What?
Stephen Hawking is shaking up the foundations of Cosmology. He recently published a paper, attempting to revise Black Hole Theory. Now the headlines say things like ‘Black Holes Don’t Exist’ and ‘Stephen Hawking stopped believing in Black Holes.’
SCI CODE with Coma Niddy - NASA’s James Webb Telescope
NASA is working on the James Webb Telescope. It’s going to be so awesome. With it we’ll be able to look further into the galaxy and learn more than ever before. Dr. Amber Straughn of NASA Goddard tell us all about this new telescope and what it can do.
SCI CODE - Sugarless Gum vs Cavities
Previously we learned that there are bacteria in our mouths that eat sugar and poop out acid. The acid can reduce the pH balance of our mouths.
pH is the measure of a solution’s acidity or basicity. Water is neutral- pH 7. And anything lower is acidic.
If the pH in our mouths drops below 5.5, acids can start to wreck your teeth. However, studies show that chewing sugarless gum after eating can help reduce acid levels.
As you chew the gum, you begin to salivate. The increased flow of saliva washes away and neutralizes the acid-turds of those sugar hungry microbes. The increased saliva also brings in calcium and phosphates to strengthen tooth enamel.
While chewing sugarless gum may be effective in laying the smack down on tooth decay, you still have to brush and floss regularly and properly for a healthy smile. No exceptions!
For more information and a list of approved sugar-free gums, check out the American Dental Association.
SCI CODE: The Dirty Truth about Cavities
Everybody poops! Animals poop, people poop, and the bacteria in your mouth poop too!
Some of the germs in our mouths love sugary foods as just much as we do. When they metabolize the sugar they poop acid. That acid can wreak havoc on your teeth.

SCI CODE: The 4 R’s of the Environment
As a kid you’ve probably heard of the 3 R’s of the Environment. Reduce. Reuse. Recycle. But did you know that there’s a 4th R? Find out what that 4th R is as Special Guest Michaela Labriole shares her SCI CODE Pro Tip.

SCI CODE: No such thing as Vegetables
Scientifically speaking there is no such thing as vegetables. So what does that make cucumbers, pumpkins, lettuce, and broccoli? Find out in this episode of SCI CODE!
Dinosaur Myths and Facts| Coma Niddy
Last week I brought you the Dinosaur Rap. This week we learn more about Dinosaurs. Join me as we explore some facts, myths, and ideas about these extinct creatures.
Dinosaur Name Rap
Rawr! It’s adventure time! Join me in a prehistoric rap song about Dinosaur names.
Did you know that Dinosaur means “Terrible Lizard?” However this name can be misleading. Dinosaurs were nothing like the lizards of today. They were reptiles in a class of their own.
So what does Velociraptor, Stegosaurus, Tyrannosaurus Rex, and other Dinosaur names translate into? To find out [Watch the Video]
Why does a breeze feel cool?
It’s summertime and it’s hot. When a breeze hits your skin it feels cool. But have you ever wondered, why does moving air feel cooler than still air?
Moving air isn’t actually cooler than non-moving air. To cool down the air, we’d have reduce how much the atoms are moving around. That’s what temperature is; the average thermal energy of atoms. The more they move, the more thermal energy they have. Sadly moving air does not reduce temperature of the air.
So if moving air doesn’t reduce temperature, why does it feel so cool?

Stay breezy my friends.
