Have you ever wondered what happens to tires once they've been worn out? Innovators around the country are finding ways to repurpose old tires into new materials such as Tire Derived Aggregate, also known as TDA. This material is often used in construction projects as a way to prevent water damage by providing an outlet for stormwater runoff. Join our Into the Outdoors Adventure Team members as they learn about all the ways TDA can be utilized to give tires a second life.

Are scrap tires a "waste material"? Maybe at one point they were, but not anymore! Scrap tires have found a second life, a way to be reused after their initial purpose. After tires are worn out and become unsafe to drive on, they are recycled for a variety of different uses. Join our Adventure Team member as she discovers all the different ways scrap tires are being repurposed!

The video here and following information are designed as an introduction and companion to the four (4)  lesson activities at the bottom of this page from our educational partners at the Great Lakes Bioenergy Research Center.

Scientists around the world agree that climate change is impacted by  humans burning fossil fuels. Then there's ozone, methane and sulfur dioxide adding to today's air pollution soup. Yet carbon dioxide, released from the constant burning of fossil fuels to produce energy, remains the 500-pound gorilla lurking in the atmosphere. From fossilized wood (coal), to natural gas (methane), to the assortment of refined fuels made from crude oil, the energy they produce powers almost every fragment of society. Essentially everything you see moving or lighting up is powered in one way or another from burning fossil fuels. Nope, there's no free carbon dioxide ticket when you turn on the TV or use your cellphone either. Chances are that your electricity to power them also comes from burning one or more fossil fuels - not to mention the various fossil fuels used to manufacture those items and countless other products we use daily.

If you asked most people on the street what fossil fuels are made from, you might be surprised at the answers. See and hear some for yourself by watching the video quiz on this linked "Energy Science" page  or the third video thumbnail on the right. The answers you'll hear might be funny or unsettling. It's logical to imagine that solid or liquid fossil fuels might be formed from something that was solid or liquid. Makes sense, right? But the science behind their formation is the same today as it was hundreds of millions of years ago when most fossil fuels were being formed.


All life, including fossils and their preserved carbon, came primarily from CO2 in the atmosphere through the process of photosynthesis. (See the linked video above on Decoding Photosynthesis to get a fresh perspective on that science.) Despite that fact, when many people see a tree or a plant, they think that the solid parts came from the soil, water, or nutrients in the ground. Though they played a role, the carbon-based materials in the plant were formed using carbon dioxide from the atmosphere that's converted to plant cells using the energy of the sun. This process of photosynthesis also accounts for creating the base of the food web in our oceans too - and was also the key in the formation of most ancient lifeforms that make up natural gas and crude oil.

Now that you're armed with all this knowledge, your logical question might be, Alright, so how can decoding the different CO2 life cycles of various fuels offer us insights to solutions for the future of the planet?  Well, that's what the video here and linked classroom lesson activities can help you discover. You really didn't expect us to tell you all the answers. Besides, we'd feel horrible cheating you out of the thrill and enlightenment of self-discovery with your peeps.

So watch the video above as your primer to become familiar with the topic, then share the free linked lessons from our educational partners with your teacher and classroom.

If you drive or ride in a car, then you burn gasoline, right? And it’s likely blended with some stuff called ethanol. So it only makes sense that you really should know what both of those fuels are made from, and maybe even how they’re made.

Natural gas also plays a vital role in your life, especially if you want to heat your home, office or school this winter. So what is it, really? And how’s it different from gasoline?

First, gather your friends or family around the computer and have everyone get ready to write down their answers on separate sheets of paper. Now start playing the video, and get ready to hit the “pause button” (II – lower left on video player screen) after one of our Energy Investigators asks one of the critical energy questions. Then have everyone write down the question and their IQ answer.

Once everyone writes their answer, resume playing the video to see what these people filling up their vehicles at the gas station had to say. Then pause the video again and start a fun debate about who has the right answer and why. When you’re ready for the next question, move on and explore all the different areas of your energy savvy.

But when you’re finished playing the quiz, will you really know all the correct answers? Maybe not. And will you be qualified to intelligently discuss the pros, cons, or science behind each critical energy question? Fear not, friend. Answers to all of the questions and so much more await you with only a few clicks of your mouse. Simply go back to the Energy Science icon on the homepage, and choose the most logical topic to discover the real science that drives your everyday world.

And stay tuned to both your television and online for our upcoming episode and classroom science videos on The reality, science and solutions to, SHAPING OUR ENERGY FUTURE.

Now that you’re thinking about biofuels… What’s your definition of a “biofuel”? And what do you think biofuels are used for?

Most of the fuel we burn in our cars and trucks is made from ancient sequestered solar energy that was converted into crude oil millions of years ago. Check out the other topics in our Energy Science category to learn more about the science of hydrocarbons. But up to 10 percent of that blended fuel actually contains modern renewable solar energy that’s been converted into what’s called ethanol, which is a type of biofuel that can help cars and trucks run cleaner and more efficiently.

If you studied photosynthesis, you know that plants, like corn, use solar energy in the chloroplasts in their leaves to covert atmospheric carbon dioxide, water and nutrients into carbohydrates; the starches and sugars that make up the plant. And during the process, plants give off oxygen, which is vital to us mammals.

In corn plants, it’s the corn seeds or kernels that have the greatest concentration of carbohydrates. That’s why they feed it to fatten livestock and poultry. Each kernel contains 62% starch, 20% protein and fiber, 15% water, and 4% oil. And it’s that converted and stored solar energy that ethanol refineries use to make ethanol. But that’s no easy feat. It requires serious science and technology as you’re about to discover as you watch this video.

Okay, we admit that harnessing the biochemical reaction of yeasts converting the carbohydrates in corn mash into ethanol is pretty slick (as ancients discovered eons ago, though they didn’t use fancy enzymes in the process).

And we suppose the ancient cultures may have used the leftover fermented mash to feed animals. But unlike ages ago, today’s ethanol production facilities produce something called DDG or “dried distiller’s grain” that is shipped around the world.

Before we get into what we do with the co-products of ethanol production, let’s first get that ethanol into your fuel tank. The process is pretty straightforward. Once it’s extracted, it’s stored then shipped to terminals where it’s blended with conventional hydrocarbon based fuels such as gasoline. One very cool reason they blend it is that ethanol actually increases the “octane” or combustion performance of fuels plus reduces burnt fuel emissions. That’s one “two-for” in dealing with ethanol. Watch the video here to get the full story.

The second “two-for” is the co-products they produce from the by-products of the process. The first biggie is DDG (dried distiller’s grain). It’s a high-protein dried corn meal that is used primarily for animal feed for both livestock and poultry. It’s gained such widespread use that it’s shipped on freighters around the world and ultimately helps feed populations in distant lands such as the far-east nations.

And just when you thought you were done with the co-products, some engineer holds up a bottle of oil… distiller’s corn oil that’s a prime feed-stock that’s used in making biodiesel. But that’s another story for later on. Be sure to check out those biodiesel science videos and lesson under the Energy category.

The future of bioenergy has come a long way since they produced Back to The Future 2 in 1989. Back then, they fictionalized the concept of putting waste products into some kind of futuristic "bioenergy converter" to power the vehicle's engine.

No, we can't put garbage into our fuel tanks yet to power our vehicles. But we have come a long way in the evolution of biofuels as scientists and engineers can now create crystal clear biodiesel from a variety of discarded cooking oils and even animal fat. One of the terms they use for this process is working with flexible feedstocks.

So why go to all the trouble, technology and expense to make biodiesel when we can get it from crude oil refineries? Experts say there's plenty of good reasons beyond the obvious reason that it makes good sense for the Planet to take waste products and recycle them into a beneficial product. Plus, biodiesel is nontoxic, is free of aromatics, increases engine "lubricity" (watch the video to learn more about that one) and yields 92% of the energy of hydrocarbon-based diesel fuel.

One of the prime feedstocks they use in making biodiesel just happens to be one of the co-products they produce from making ethanol, another form of bioenergy - DCO or distiller's corn oil. Pretty cool loop when you think about it. So really, animal fat derived from animals eating plant (corn) carbohydrates, used cooking grease (that probably contains corn oil) and distiller's corn oil all connect with renewable corn crops grown in America's heartland.
