Comedian/scientist Bill Nye stars as the host of this show designed to get kids interested in the science of everyday, and some not-so-everyday, things. On a full range of subjects, including ecology, biology, chemistry and physics, Nye gives an easy-to-understand, yet informative lesson that both kids and their parents can enjoy.
Some answers, my friend, do in fact, blow in the wind. A cool breeze is great on a hot summer day. A cold winter wind can chill you until you can't stop shivering. Where does all that wind come from? It starts with the Sun. Energy from the Sun warms the Earth and the atmosphere, the air, above it. As the world turns into darkness each night, the atmosphere cools off. The molecules in a mass of warm air are more spread out than the molecules of air in a cold air mass. So cold air is heavier than warm air. Cool air masses squeeze warm air up. That's why you may hear people say, "Warm air rises." The Sun warms the Earth with huge amounts of heat each day. And, the Earth is spinning. So, as air masses move up and down, they get nudged sideways along the Earth's surface at the same time. Try drawing a straight line on a spinning ball. It'll curve. The same thing happens to make wind. Air travels all over the Earth moving across deserts, up and down mountains, through valWatch Now:AmazoniTunes
Wetlands are not just home to different animals and plants, but they also control flooding and help keep the Earth’s water clean. Flood waters move more slowly through wetlands because they have to go through barriers of plants and dirt. Wetlands help stop erosion because the plants stop the soil from washing away. Plants and soil in wetlands slow water enough that bacteria and other decomposer organisms can break down and even absorb some types of pollution. Wetlands are wet. Let’s keep them that way.Watch Now:Amazon
Atoms are reeeeally small. They are so small that you can’t see them with just your eye. It takes as many as 10 million of them side-by-side to measure a single millimeter. In fact, atoms are the smallest pieces of “stuff” that are still considered “stuff.” If you take something and break it into tiny pieces, and then break it into tinier pieces, and keep going, the smallest part you’d be left with (and still have the same substance that you started with) is an atom. Atoms are the building blocks of all matter. Everything is made of only 109 different kinds of atoms, called elements. 92 of these elements occur naturally, but the rest of them – ones like Technetium and Promethium have only been found in distant stars and Californium and Einsteinium – are only made in laboratories. A molecule is born any time two or more atoms combine together.Watch Now:Amazon
The momentum of a moving thing, like you riding your bike, depends on how much mass you and your bike have and how fast you’re speeding down that hill. An elephant on a bike has more momentum than a mouse on a bike moving at the same speed. A mouse on a fast bike has more momentum than a mouse on a slow bike. If there’s an elephant on a fast bike, you’d better get out of the way.Watch Now:AmazoniTunes

The air that surrounds Earth is called the atmosphere. Compared to the size of the Earth, the atmosphere is very, very thin. It’s made from gases – mainly nitrogen, oxygen, and water vapor, with a little argon, carbon dioxide, xenon, neon, helium, and sulfur. The atmosphere does a lot for Earth. It blocks ultraviolet light and burns up a lot of meteors. It traps in heat, keeping Earth cozy. Even clouds are formed in the atmosphere – keeping the Earth wet with rain.Watch Now:Amazon

It's time for Bill Nye to shed a little light on electricity. Electricity might seem mysterious, but once you understand the science the light goes on (so to speak). You flip a switch, and the lights turn on. You push the play button, and your personal stereo starts playing music. When you flip the switch or push play, you start a flow of electrons. Electricity is the flow of electrons, and electrons are very tiny charged particles. Electrons are found in atoms, the tiny pieces that all stuff is made from. We can make electrons flow in two ways. Batteries make electricity by mixing up chemicals -- making a chemical reaction that forces electrons to move in a path from the battery to the personal stereo and back to the battery. Electricity that turns on lights in your home is made by power plants. Most power plants use big machines called generators to make electrons by twirling wire in a magnet. The magnet makes electrons in the wire move around, creating electricity.Watch Now:Amazon
Surf's up! Get the current information as Bill Nye explains why oceans are salty and explores the ocean currents. Go with the flow of ocean currents with Bill Nye the Science Guy. Most of the Earth is covered with water - we're talking 71% of the entire Earth, and most of that water is in oceans. It depends how you count, but you can say that there are five oceans on Earth - the Atlantic, the Pacific, the Indian, the Arctic, and the Antarctic. They are all connected into one World Ocean by the flow of ocean currents. Ocean water is moving around all the time. Some of the moving water forms rivers in the ocean. Oceanographers, scientists who study oceans, call these rivers of ocean water "currents". Currents help sea animals move around, they bring up deep ocean water with lots of nutrients for small animals to eat, and they push warm and cold water around, creating different climates in the oceans. As the sea surface gets warmed by the Sun, water evaporates, but salt stays in the seaWatch Now:iTunes
Join Bill Nye as he counts down the hits from the Soundtracks of Science. Along with the music, Bill does a few new experiments on the lab bench. You’ll see the grunge band Nyevana’s classic “Air Pressure,” Momentisey’s “The Faster You Push Me,” and divas En Lobe’s “Whatta Brain.” There’s even a special appearance by Mudhoney, a real band from Seattle. But if you want to know who’s the number one artist from Not That Bad Records, you’ll have to tune in.
A plant’s recipe for food has only three main ingredients: sunlight, carbon dioxide, and water. When plants make their food, they give off what animals need – oxygen. Without oxygen, animals like us wouldn’t be able to breathe. If plants weren’t here on Earth, we wouldn’t be here.Watch Now:Amazon
Energy, things like light, heat, and sound, moves in waves. You’ve probably seen waves in the ocean, or ripples when you throw a rock in a pond. Moving energy is not like the wave you do with your hand.Watch Now:Amazon
Every time you look at something, hear something, touch something, smell something, or taste something, your brain collects a little information about the world around you. You may even have a scrapbook to store memories of some of that information. There’s a lot out there though. How do people sort out the valuable information from the not-so-valuable?Watch Now:Amazon
Each planet is different. They are all different sizes – Pluto’s the smallest, and Jupiter’s the biggest. They come in a variety of colors – Mars is covered with rust, so it looks red; the methane (cold natural gas) in the atmosphere of Uranus makes it look blue; and Saturn’s colorful rings are made of icy rock. As far as we know now, Earth is the only planet in our solar system that is home to living things.Watch Now:Amazon
There are lots of different climates all over the world. Deserts are warm and dry. Temperate forests are cold and wet. Tropical rain forests are warm and wet. Animals and plants live in climates that are good places for them to live. Cacti wouldn’t grow too well in the Arctic, just like polar bears would over heat in the desert.Watch Now:Amazon
In this show, you can Bone up on Muscles. When you clicked on the Nye Labs web site to read this, you used your bones and muscles. Without them, you can't click, surf, or even sigh. Bones and muscles work together, or you aren't going anywhere. Muscles always pull, even when you push on something like a door somewhere in your body your arm and leg muscles are in tension. They are all attached to bones, and those bones are pushing; they're in compression. By pulling on bones you can breathe, talk, and move all over the world. Your bones support your weight like beams of steel or wood. They're stiff and strong. Rigid as they might seem though, they do flex. And, if you bang one hard enough, it swells up. You have a lump. That's because bones are full of blood vessels. Bones are not solid like rocks or skeletons in a dinosaur museum. Bones flex and grow. In fact, putting healthy amounts of stress on your bones is good for them. The flexing helps them get nutrients andWatch Now:iTunes
Are you tense? Need some structure to your life? Then tune in to Bill Nye the Science Guy as he explains the science of structures. All structures give support or create a shape. You can find structures everywhere. Bridges, buildings, chairs, shoes, plants, spiderwebs, tables, and even your own body are all structures. A structure's shape, size, and what it's made of depend on what the structure does and how strong it needs to be. When structures give support, they either experience a pull (tension) or a push (compression). Structures in tension, such as ropes, cables, or blimps are made from stuff that is good at pulling. The materials in tension are usually thin. Structures under compression, such as elephant legs and courthouse columns, are made from hard stiff stuff. Compared to structures under tension, structures under compression are much thicker. When it comes to structures, form (the size and shape) depends on function (what it does).

Energy can change forms. Your body changes the energy in food into energy you can use to do things. Dams turn the energy in falling water into electrical energy to bring power to your house. Sound energy changes into moving energy (like when the bass is so high you can feel the floor move).Watch Now:Amazon
More than 22,000 different species of fish live in the oceans, lakes, and rivers of the world. Fish come in all shapes and sizes. Some eat water plants, some eat other fish. Lampreys and some jawless fish suck onto other fish for food. Stone fish live on ocean bottoms and camouflage themselves as rocks. Puffer fish blow themselves up like a balloon, only they’re covered with spines. There are tons of strange and cool-looking fish everywhere.
Probability is a way to measure how likely it is that something will happen. Probabilities are predictions. They’re often just very careful guesses. When a scientist wants to calculate a probability, she or he gathers data and then uses the data to make her or his guess. Probabilities are between 100% (it’s definitely going to happen) and 0% (forget about it, pal, it’s not going to happen). Most things have a probability somewhere in between.Watch Now:Amazon
The color of your eyes, the shape of your nose, and the straightness (or curliness) of your hair depend on your genes. Not jeans the pants, but genes, the long strands of chemicals in your cells. Genes are like a blueprint for your body, and your cells follow the blueprint to build you. All living things have genes in their cells. You get your genes from your parents – half from your mom and half from your dad. Your parents got their genes from their parents, your grandparents. Living things pass down their genes from generation to generation. Genes from a mother’s egg cell mix with genes from a father’s sperm cell to make a complete set of plans for a baby. Baby humans, baby dogs, and baby plants all grow up to look like their parents because of genes.Watch Now:Amazon
Bill's all charged up about the "Static Electricity" show. It happens to all of us. You're causally walking along, maybe dragging your feet a little, when you reach out to shake a friend's hand and - ZAP! Both you and your friend get shocked. The spark is static electricity, a buildup of charged electrons. Electrons are a part of all atoms, the building blocks of all stuff, including you and me. All electrons have a negative charge. Negatively charged electrons push away from other negatively charged electrons. Like charges repel each other. When electrons build up in an area, a charge builds up, and it's just waiting to be released. This buildup of charge is called static electricity. Charges can jump around between things, especially when things are rubbed together. When you drag your feet on the carpet, electrons from the carpet jump onto you. As the charge builds up, the electrons get too close to each other, and they need a place to escape. They get their chancWatch Now:AmazoniTunes
The show is way out there, way far away. After all, it's in Outer Space. When you look at the night sky on a clear dark night, you can see thousands of stars. There are far more than you could count. And, they are way out there. They are very, very far away. It's about the hardest thing to imagine about space. Let's talk about the nearest star to us, the Sun. If somehow outer space were not an icy cold vacuum with nothing to eat, drink, or breathe, and we could drive there in a car, to get to the Sun at freeway speed of 100 kilometers/hour (61 miles/hour), it would take171 years of driving without stopping to sleep or get gas out in the near nothingness of space. That's just to the Sun. To get to even the closest star, Proxima Centauri, would take 40,000 years. On top of that, most things, billions and billions of stars, are much, much farther away than that! It is just astonishing. How do we know that everything is so far away? We have watched the sky for centuries.Watch Now:Amazon
You can't see them, but they're everywhere even inside Bill Nye. This is not science fiction, it's the science of cells. All things that live are made from cells. You can't see them, but every part of your body, including everything inside your body, is made from cells. Cells eat, they grow, and they make more of themselves (what scientists call replicate). There are millions of different types of cells. Dog cells are different from fish cells. Bird cells are different from your cells. And inside your body, there are many different cells, each one doing a different job to keep your body going. Cells may be tiny, but without them, we'd be nothing.Watch Now:Amazon
