Dr. Universe: Do you have any experiments you can recommend? Thanks! -Etta, 7, Milwaukee
Dear Etta and Friends:
You can try all kinds of fun experiments at home. It really all depends on what you are curious about. Lately, I’ve seen some really great sunsets and started wondering what gives them their colors.
I decided to ask my friend Tom Johnson, who leads fun physics demonstrations for kids visiting Washington State University. I asked him if he had any simple ideas for an experiment I could try out in my lab, or even the kitchen. One idea he had was to create a … » More …
Dr. Universe: How do we get our personality? – Jamie, 11
Everyone is different. Maybe you are adventurous, shy, outgoing, funny, or kind. Before you were even born, your unique personality was beginning to take shape.
Part of the answer to your question is that some of your personality comes from your parents. Just as parents pass down physical traits like hair and eye color to their offspring, they can also give them different personality traits. They’re in your genes, the information passed throughout generations.
But your personality isn’t set in stone from the beginning. There are a few other things that go … » More …
Why do cows moo? -Sam, 11, Gahanna, Ohio
If you’ve ever been near a herd of mooing cows, it might have sounded like all their moos were the same. But just as each person’s voice is a little different, so is each cow’s moo.
Human ears might not always pick up the small differences in moos, but cow ears sure can. In fact, cows have great hearing. They can even tell that different moos mean different things.
Can video games help us learn? – Isaac, 12, Clyde, N.Y.
All kinds of games can help us learn, including some video games. They can be a fun and useful way to help you remember what you learn, too.
Our brains work hard each day to take in and process information. Ever since video games were invented, people have been asking if and how they might change our behavior and brains.
For example, people once thought that video games left players with poor eye-sight and poor attention. … » More …
Dear Dr. Universe: Why does hair turn gray? –Darae, 10
Hair comes in lots of different colors. There’s black, medium brown, auburn, light brown, strawberry blonde, and copper, to name just a few. But in the end, almost everyone will have hair that’s gray or white.
Ever since you were born, different cells have been working on your hair. Each hair sprouts from a follicle, a sort of little hair-making factory under your skin. Here, some of your cells are making your hair and others are coloring it.
The cells that color your hair are called melanocytes. They produce a pigment, or natural … » More …
Dr. Universe: Why do we get a fever when we are sick? – Marcelina, 11, Ovid, N.Y.
Lots of warm-blooded animals get sick, including cats. I’ve had a fever before, but I wasn’t entirely sure why we warm up when we get sick. I decided to ask my friend and professor Phil Mixter at Washington State University.
Mixter is curious about the germs, or microbes, that we all carry around with us. In fact, scientists estimate that humans carry more than 100 trillion of these tiny microbes with them wherever they go. Not all of these microbes are bad, but some of … » More …
Dear Dr. Universe: How does a light bulb work? When one bulb in a string of lights goes out, why do they all go out? – Molly, 8
Just the other day I was taking down a string of lights from my lab, when I discovered the bulbs were burnt out. I visited my friend Aaron Crandall, an engineer at Washington State University, to see if I might get them working again.
Crandall explained when you plug in a string of lights to a power source, like an outlet, an electrical charge flows into the wires. A lightbulb works when an electrical current … » More …
Dr. Universe: Why do some animals live in groups?
– Mrs. Rubert’s students, Foothill Knolls STEM Academy of Innovation, Upland, Calif.
Dear Mrs. Rubert and Students,
Fish swim in big schools. Baby ducks waddle in a straight line. Ants and bees divide up labor. The world is full of animals that live in groups and they do it for a few different reasons.
For one, living in groups helps some animals avoid getting eaten by predators. Some even join forces to take down … » More …
Dr. Universe: How is glass made? And, what is it made out of? What about thick glass like they are putting up on the Space Needle? – Tali, almost 8 years old, Seattle, Wash.
We can make glass in factories and we can find it in nature. Some volcanoes make glass. When they spew out lava, it often cools into obsidian, a black glass. Glass can also form on sandy beaches. Small tubes with smooth glass on the inside may appear after super-hot lightning strikes the sand.
In fact, sand is one of the most important ingredients we use to make glass. We … » More …
Dr. Universe: Do all animals pass gas? Do cats fart?
Hasandi, 11, Jeddah; Harrison, 10, Albany, Ore.
Dear Hasandi and Harrison,
If you’ve ever been near a cat or dog when they tooted, the smell might have sent you running right out of the room. A lot of animals pass gas. But believe it or not, some animals do not.
First, let’s talk about the gassy ones. When us cats and humans eat food, we are also swallowing air, or gas. It’s made up of elements like nitrogen and oxygen. The gas travels down into our digestive system and can take up space in … » More …

Many years ago when I transitioned to dairy free living, I sadly gave up my coffee creamer. Having served in the U.S. Marine Corps it should have been an easy transition back to black coffee (lol!) but it wasn’t. Over time, I got used to a new way of dairy free healthy living. If the […]

“I think we can all do things. Sometimes fear holds us back. Maybe when people read this story, they’ll think: If she can do that, we can adopt a kid and give them a life.”~Julia Griffith
