We are super excited to release our first podcast in our new series, Show Me Some Science! These short podcasts are designed to be used in the classroom or incorporated into your lessons.In this episode we look at wave interference. When two waves meet they can interact before they pass through each other. They can add up or cancel out and this is know as constructive and destructive interference.

In this last segment of the mixtures episode, Brian shows how fun and delicious it is to mix Carbon Dioxide and water!

The Colorado Rockies, 9News and Colorado State University are teaming up to launch the Fifth Annual Weather and Science Day at Coors Field on April 23, 2014.Here’s a video of the Little Shop of Physics Team getting ready for the big event!
-
Rivers can be a great example of mixtures, when the water carries rocks, sand and clay and deposits them in different places. Join geologist (and EverDay Science Producer!) Herb Saperston as he explores mixtures along the Podure River.Also, we look one last time at mixing and unmixing. This time the secret ingredient is salt!
-
You may have never thought about this, but milk is a mixture of different substances including proteins, sugars, and water. Learn how to "unmix" milk to make curds and whey!
-
Last time we saw that it is possible to unmix a mixture, or separate it into it's constituent parts. This week we will learn how to unmix different types of plastic so they can be recycled. And we'll learn how to unmix sand from Dominica.
-
Empedocles was an ancient Greek Philosopher and the first Western thinker to propose that everything in the world was a mixture of basic substances. He believed the four elements were Earth, Air, Fire and Water.In this podcast we also look at physically un-mixing, or separating out mixtures into their basic substances.
-
Cocoa does not like to mix with cold water. Brian and the team use emulsifiers, heating and good old fashioned stirring to get the cocoa to mix in for a delicious beverage!
-
We've already seen that oil and water don't mix. In this episode, we see how we can use this to propel little paper "boats" on the surface of water.
-
Magic Sand is specially treated sand that does not get wet! Another way of thinking of it is that it does not mix with water. At all. We play around with magic sand and then find a way to get it wet!
-
First we play around with cornstarch and water a little bit more. Then we see what happens when you try to mix oil and water!
-
This is our first podcast from a new EveryDay Science Show. The show is titled Mixtures and we will start off by looking at cornstarch and water. Sometimes it behaves like a liquid and sometimes it behaves like a solid. It all depends on the forces involved!
-
Do you think the moon looks bigger when it's close to the horizon that when it's straight overhead? Well, it's just an illusion...and we can prove it! And we will take a look at EveryDay Science! behind the scenes!
-
When you see objects next to each other, your brain makes certain assumptions. It's possible to trick your brain into seeing things in different ways! Magicians use some of these tricks which are referred to as "smoke and mirrors."
-
You might not think of paper as being exceptionally strong, but the again you might be surprised. In this segment you will see paper pulled as hard as we can and also paper supporting a 40 pound cinder block!
-
If you pull paper one way it's easy to tear but it you pull it another it's not. Brian and the students see if they can hang from a newspaper.
-
Students can disappear and seem to catch on fire using a green screen. Check out how this works!
-
Check out the world of ultraviolet florescence. Plus drinking glowing Martian Soda with mustaches! Also, get out your 3D glasses (or see the video on how to get a pair!)
-
Brian and the students use tape to make stained glass windows that can only been seen with polarizers! Also, a surgically altered calculator which switches colors depends on the angle!
-
Light, like any wave, can be polarized. That is to say that the wave can wiggle in certain directions. See what happens when you filter out light that is wiggling in a certain direction!
