Pretty much every living thing on our planet—from a blue whale to a tiny ant—has something in common. We all have cells, which are the building blocks of life, and inside of those cells we have DNA. My friend Gunjan Gakhar, a teaching assistant professor in biology at
Think of your favorite song. Maybe it brings you happiness or joy. Maybe it makes you want to start dancing. Or maybe it’s a sad, melancholy song, but you still really like it. From the radio to concerts to our mobile devices, music is all around us. To find out exactly why people like listening […]
When humans want to look into the past, they often dig into the ground. Under the soil, archeologists can find all kinds of things that help us learn about life long ago. That’s what I found out from my friend Rachel Horowitz, an archaeologist at Washington State University who is very curious about the lives of […]
Each year during the fall, we often see a lot of trees dropping their leaves. To find out exactly what happens when leaves fall, I talked to my friend Henry Adams, a researcher at Washington State University. Adams is very curious about the lives of trees and how they can survive harsh conditions. He reminded […]
On Earth, humans have oxygen to breathe. But there’s very little oxygen to breathe in space. Space is actually a kind of vacuum, which means there isn’t a whole lot of matter, or stuff, out there between the planets and the stars. For Earthlings like you and me, oxygen is an essential part of life. […]
When you walk around on land, you are walking on top of Earth’s rocky crust. Below the crust is another thick layer of rock. These layers form Earth’s tectonic plates and when those plates collide with each other, they often form mountains. To find out about how mountains form, I visited my friend Julie Menard, a […]
Our planet is home to all kinds of different plants, and they help make a lot of the oxygen we breathe. To find out how plants make oxygen, I asked my friend Balasaheb Sonawane, a scientist at WSU who researches photosynthesis, or the ways plants use energy from the sun and make oxygen. He said that […]
About 300 years ago during another pandemic, there was a person named Sir Isaac Newton who spent a lot of time at home thinking about the universe. He was thinking about how objects fall and started to wonder if the same force that made objects fall also kept the moon in its orbit. He called […]
Snakes have an amazing sense of smell. They can use their tongues to pick up on all kinds of scents in the air. Whenever we smell something in the air, we are actually sniffing tiny building blocks called molecules. These molecules are what make up the scents of everything around us—things like baked bread, fresh-cut […]
There are all kinds of different birds on our planet, and they migrate to different places. My friend Heather Watts, a researcher at Washington State University, is really curious about bird migration and told me more about how birds know where to go. She said there are some birds that make a round-trip flight when they […]
