Back in April 2017, the ‘Science Brothers’ spread their wings and traveled all the way to a fellow Naval Surface Warfare Center in Carderock, Maryland to participate in their annual ‘Take Our Daughters and Sons to Work Day.’
Dan, Kinsey, and Gavin Science take the stage to wow the crowd in MD!
Chemical experiments don’t always turn out very pretty…
Hey look, it’s like a lightsaber!
Special thanks to our lovely science assistant of the day! Sometimes you just can’t do science without a little help from a friend.
We hope the show was enjoyed by both the children and their parents!
A very cool experiment that I do is a demonstration of the properties of different gases. The air around you is actually made up of a number of gases mixed together, and we use the oxygen in it when we breathe – it is 78% nitrogen, 21% oxygen, and 1% other gases (mostly argon and water vapor). As you can see, air is actually made up of mostly nitrogen, a mostly unreactive, or inert, gas. There are lots of other gases, though, and a few of them have some really exciting properties.
Most people are very familiar with glow sticks – we see them all the time around holidays like Halloween or Independence Day! Even so, glow sticks are still amazing to see in action. They create a soft light of just about any color that lasts for hours or days, and do this without producing any heat whatsoever (unlike electric light bulbs, which get super hot!). We create a glow stick reaction during our show that is super bright but doesn’t last very long, and do a neat experiment by mixing two different colors to see what happens.
Way back in 2011, I posted about a neat color change experiment called The Chemical Chameleon. Nowadays, we do a different demonstration in its place called the Chemical Traffic Light. This one is great for presentation because it is actually repeatable, which is pretty rare in chemistry! (Image credit)
In this experiment you will build your own cold lava lamp! Regular (hot) lava lamps work by heating up wax inside a glass bottle that also has water in it. The hot wax expands a little and becomes less dense than the water, so it floats to the top in large blobs. When it cools back down, it becomes denser and sinks back to the bottom to be heated up again. You can recreate this same effect at home using a different principle and easy-to-find materials!
Every year the Naval Surface Warfare Center holds a Christmas party for disadvantaged children in Leon county. These are the kids that would not normally have a Christmas at home. The PAO here makes sure these kids get to have some holiday magic, and this year they asked the Science Brothers to bring in some science as well!
On April 8, 2011 the ‘Science Brothers’ visited Hiland Park Elementary School. This was the first show by the Science Brothers at an elementary school; and the media was there. Were we nervous? You bet we were!
So nervous we forgot to take pictures! O well. But Channel 13 did interview us between shows, and filmed our first show in it’s entirety. They were gracious enough to give us the news stories. You can watch them below:
And we were also on the cover of the local newspaper! (click for full size)
