In our first animated jingle, the Boneheads teach us that kids really do have the power to make a difference and start saving our planet right now. One simple thing we can all do is to turn off the water when you brush your teeth. You'll save about 2 gallons every time you brush.Saving water also saves energy - the energy used to collect, treat and pump it. This, in turn, cuts down on the greenhouse gases that are released into the atmosphere and fights global warming. That s right, you can do all that by simply turning off the water while brushing your teeth. See, it s easy to be a planet protector. So act now and make planet Earth a great place to live. After all, it s your planet too!

You've heard of optical illusions, but have you ever tried a "nose illusion"?

There are almost as many species of primates as there are days in the year. And each species of primate is unique and special. They range in size from the tiny pygmy mouse lemur that weighs about an ounce to the gorilla weighing up to 600 pounds!Each of the IPPL member organizations devote themselves to conservation and protection of primate species native to their area, or to primates imported into their area that need sanctuary. Dr. Shirley McGreal devotes her sanctuary in South Carolina to the rescue and care of the smallest of the ape family, the gibbon, the acrobats of the southeast Asian forests.Caring about and respecting wildlife is the right thing to do. We re grateful to people like Dr. McGreal who have kept their promise to the primates. The solution to threatened and endangered species seems simple: Let primates remain in their natural habitat where they can happily sing, swing, forage for food, and raise their young. If we can allow them to do this, these precious primates will be around for many years to come.

Try this fun way to learn about sound and vibration, while making lots of strange sounds.

Can you balance a hammer, a ruler, and a piece of string on the edge of a table? Of course you can.

Use this simple science experiment to see how the pull of gravity varies on different plantes.

This week's experiment came from a question asked by a student during my energy show. He wanted to know how microwave ovens work. For this experiment, you will need: 3 identical, microwave safe containers water cooking oil a microwave oven I used small drinking glasses, but any microwave safe containers should work. Put about an inch of water into one glass, about an inch of cooking oil into another and left the third glass empty. Place all three glasses into the microwave oven. Set the time for 15 seconds and start the oven. When the oven stops, open the door and carefully remove all three glasses. Carefully feel the outside of the glass of water, at the water level. It should feel quite warm. Making sure not to burn yourself, carefully touch the surface of the water. It should also be quite warm, possibly even hot. Do the same thing with the glass of cooking oil and the empty glass. What do you notice? The glass of water heated up nicely, but the glass of oil, and the empty glass did not. Why? It has to do with how a microwave oven works. Inside the oven is a tube called a magnetron. This magnetron broadcasts microwave radiation. RADIATION!!!! Oh, no! Is my food radioactive? No. There are many kinds of electromagnetic radiation, such as radio, television, radar, and light. Microwaves do not make your food radioactive. So how to the microwaves cook your food? They cause the water molecules in the food to vibrate. Why just the water molecules? Water molecules are polar. That means that one end of the water molecule has a positive charge and the other end has a negative charge. As the name suggests, microwaves are waves. They are not waves of water, but waves of electromagnetic energy. Just as a wave in water can cause an object to bob up and down, the microwaves can cause a molecule of water to vibrate first one way and then the other. As the wave approaches the molecule, the positive end is pulled one way and the negative end is pulled in the opposite direction. As the wave passes, the pulls are reversed. This causes the water molecule to vibrate back and forth rapidly, which makes it hot. The water molecule then passes some of the vibration to surrounding molecules, making them hot too. Oil is not a polar molecule. That is the reason that oil and water do not mix easily. Polar molecules stick to other polar molecules, but not to nonpolar ones. Because the oil is not polar, it is not heated by the microwaves. That is why we cannot fry things in the microwave. But wait a minute. I have had bacon cooked in the microwave. What about that? The bacon contains water as well as the fat. The water in the strip of bacon provides the heat to cook it. The fat just drains away. It will be hot, having been heated by the water in the bacon, but it will not continue heating once it drains away. Dry foods do not cook well in the microwave oven. Remember that the empty glass did not get hot. You need the polar molecules in the water to get the heat for cooking. Now, lets get back to the RADIATION. You might have heard that microwaves change the chemical structure of the food. Yes, cooking food with microwaves does change the chemical structure of the food. So does any kind of cooking. That is the reason we cook food. If you don't want the chemical structure of your food changed, eat it raw. Food cooked in a microwave oven is just as nutritious as food cooked by other means. It is not radioactive and not dangerous, as long as you don't burn yourself with it or drop it on your foot. On second thought, if you count eating too many microwave brownies as dangerous, then you could count my microwave as a hazard area. Have a great week.

Every night on Planet Earth, ponds, lakes, streams, marshes, and even forests come alive with the deafening chorus of lively amphibians called frogs. In this episode, we will explore some of the lesser-known habits and habitats of frogs and toads. We will also explore a new threat to frogs and amphibians that is capable of wiping out thousands of species of these beloved and essential creatures.Luckily, with the help of Planet Bonehead, and people like you all over the world, a consortium of scientists, biologists and wildlife experts, who are members of Amphibian Ark, have taken on a huge task that will save countless species of frogs and toads from extinction.Amphibian species are becoming extinct at a pace faster than anything we have ever experienced, and we need to spread the word. If we lose thousands of amphibian species, it will have an effect on our environment and on species all the way up the food chain.

Have you ever wondered why some flames are yellow, while others are blue? Growing up, I was always told that it was a matter of temperature, that hot flames were blue and cooler flames were yellow. While there is a temperature difference, that difference is a "symptom" of what is going on, not the cause of the color difference. For this experiment, you will need: a candle with a holder. This can be as simple as some aluminum foil balled up around the base of the candle and flattened on the bottom. a lighter a wooden toothpick a white plate As we will see, even though the candle flame looks yellow, it is not. The actual flame is blue. You can see this by lighting the candle and looking very closely (not too close or you could lose your eyebrows!) at the base of the flame. Along the outer edge, you will see a thin, blue edge to the flame. It helps to be in a dark room. This is the color of the actual flame. The yellow color is caused by solid material burning inside the flame. When a solid burns, it does not produce a flame. Instead it glows. You have probably see this glow on burning charcoal. You can also see it by carefully lighting the end of a wooden toothpick and then blowing out the flame. You will see the orange glow of glowing combustion at the tip of the burned toothpick. Does that mean that there is solid stuff inside the candle flame? Let's find out. Light the candle and be sure it is steady and won't fall over. Hold the bottom of the plate in the candle flame for a few seconds. When you remove the plate, it has turned black!!! Don't worry. You have not ruined it. Let it cool for a minute. Remember, it is HOT! Once it has cooled, rub your finger over the black spot. The black rubs off. Now, go wash your hands, to get rid of the black stuff. What is that black stuff? It is called carbon and it comes from the candle wax. As the candle burns, the wax comes apart to form several chemicals. One of these chemicals is carbon. The tiny bits of carbon burn inside the candle flame, giving off the yellow glow. If the candle wax did not produce this carbon, the candle flame would be blue, like the flame of a gas stove. You may have noticed some black smoke while the plate was in the flame. That smoke was made up of the tiny bits of carbon. Normally, the carbon burns, combining with oxygen to form carbon dioxide, a colorless gas. The spoon let some of the carbon get out of the flame without burning, producing smoke instead. When you see black smoke coming from a fire, it is usually made up of tiny bits of carbon.

Hopefully you spent some time stuck in traffic to think about last week's experiment. Did you actually try it? Very good! If you did, you saw that the tall candle goes out before the short one. Why? First, lets think about what is happening as the candle burns. Oxygen from the air is combining with the carbon and hydrogen from the candle wax, to form carbon dioxide and water vapor. During this process, chemical energy in the wax is converted into the light and heat energy of the flame. If the supply of oxygen runs low, then the candle flame gets smaller and goes out. But why would the tall candle go out first? The carbon dioxide and water vapor do not mix evenly in the bottle. They are quite a bit hotter than the air in the bottle, so they spread out, and are less dense. This causes them to rise to the top of the bottle. Think of it like filling the bottle with water, only in reverse. Water is denser than air, so if you poured water into the bottle, it would go to the bottom. As you added more water, the level would rise, until it put out the shortest candle. Now reverse that. The hot carbon dioxide and water vapor rise to the top of the bottle. As the flame produces more and more of the hot gases, their level moves downward from the top, until it reaches the tallest flame. As the flame is surrounded, it runs out of oxygen and goes out. The shorter candle is still surrounded by the denser, oxygen rich air, so it continues to burn for a while longer. I hope you really did try the experiment. It is much more fun when you actually do things instead of just reading about them. For example, it is interesting to read about a large bowl of ice cream, covered with hot fudge sauce and a sprinkle of chopped pecans, but it is so much better to actually experience it yourself. Sounds like a great idea to me. Have a wonder filled week.

This experiment will give your brain some exercise, and will really get you thinking about air. You will need: 2 candles a lighter a glass jar at least 3 inches taller than the candles foil a knife Use the knife to cut one of the candles so that it is at least 2 inches shorter than the other. The other option is to find candles that are different heights to start with. Crumple the foil around the base of the candles to hold them upright, side by side. We are going to light both candles, and then place the jar over them, but first lets think about what is going to happen. What do you think will happen? As the candles use up the oxygen in the jar, will both of them go out at the same time? If one goes out first, will it be the tall one or the short one? Why? Think about it first, before you actually try it. OK, have you thought about it? Have you formed a hypothesis? That means not just guessing which one will go out when, but actually coming up with a logical explanation for what you think will happen. Now it is time to test your hypothesis. In other words, do the experiment! OK, what happened? (Did you think that I was going to tell you?) Yes, I know that at this point I usually explain things, but now and then it is fun to let you try the experiment without knowing beforehand how it will turn out. Don't worry. All you have to do is try it and you will find out, or wait until next week.

This week's experiment is a fun trick that is useful too. How can you pour a glass of soda without getting a glass that is half soda and half foam? To find out, you will need: 2 glasses ice carbonated soda Take some ice straight from the freezer. Put a few cubes into a glass and pour in some carbonated soda. You will get lots of foam and fizz. Next, put some more ice into the second glass. This time, fill the glass with water and then pour the water out. Pour in the carbonated soda and observe. This time, there is much less foam. What is happening? What is the difference between ice fresh from the freezer and "wet" ice? Comparing the surfaces of the two, the wet ice is much smoother. The fresh ice has a surface with lots of rough spots and irregularities. Why would this make a difference? The carbonated soda is a liquid with a gas dissolved in it. This gas (carbon dioxide) easily comes out of solution, forming bubbles. Rough surfaces give the gas bubbles a better place to form, producing more foam. You can see this by trying another rough surface, some grains of sugar. When you sprinkle the grains of sugar into the soda, it foams up. If you dissolve the sugar in a little water, you can add the solution without the same level of foam. You could do the same thing with a little salt, but then you would not want to drink the soda afterwards. It would be a shame to let it go to waste. You would not believe how much soda I drank while researching this one. Sometimes we have to make sacrifices in the name of science. Have a wonder-filled week.
