Ecology |
We're all joined in a living web known as an ecosystem. Link ecosystems together and you get an even larger system called a biome. Rain forests, grasslands, and deserts are some of Earth's largest biomes. As the video points out, the most important thing to understand about an ecosystem is that everything in it is interconnected. Change one thing and all the others are affected. That's why human actions are so important. What we do can affect the whole system. This is made clear on the Galapagos Islands, where human introduced species have wreaked havoc on native animals such as giant tortoises. Peeks into rain forest and desert ecosystems reveal the intricate webs. A look at a Serengeti food chain defines one strand of such a web. |

Ben Franklin didn't discover electricity, but he was the first to realise that lightning was electricity and to name positive and negative charges. It would take another 100 years before Thomas Edison invented the light bulb. Now, there's scarcely anything in our lives that doesn't run on electric power: from toasters to spaceships. Even the human body depends on electrical impulses created by chemical reactions among cells to transmit impulses. We've also learned how to use electricity to regulate a heartbeat, help a deaf person hear, even use an artificial limb. Keeping the power flowing can be a dangerous job, as one lineman who flies to his job sites can attest. But somebody's got to do it, as the United States produces more electric power than any other country. |

Forces and Gravity |
Sir Isaac Newton was quite the guy, devising the theory of gravity and specifying the three laws of motion. Forces affect everyone and everything, but no one had defined them until Newton. One of the factors that can affect objects in motion is friction. It's easy to understand how friction between a door and its hinge can make the door more difficult to open. It's more difficult to understand how air creates friction, called drag, and slows down everything from butterflies, to people, to airplanes. Gravity isn't just an Earth phenomenon. It's the force that holds stars in their galaxies and planets in orbit around stars. We've learned to use gravity and the forces of motion to keep satellites aloft and airplanes in the air. To do the latter, we took a lesson from the birds. The shape of an airplane wing mimics that of a bird's wing. It's the shape of an airfoil, and the way air moves across it causes lift. Nowhere can you be more keenly aware of gravity and motion than at an amusement park. There, gravity and centrifugal force can make for a wild ride. |

Paleontologists regularly dig treasures out of the earth in the form of fossils. These remains of once living things can tell us much about life in the past. And using modern technology, even more discoveries are coming to light. For example, fossilised remains captured in amber contain soft tissue such as organs, perhaps even DNA. The body of a wooly mammoth discovered in 1997, in Siberia, had preserved hair and soft tissue. The hundreds of fossilised animals found in Nebraska's Ashfall Fossil Beds appear to be a snapshot in time, as the animals were quickly preserved in volcanic ash. Scientists aren't sure what creatures made mysterious tunnels in Mammoth Cave National Park, but they'll keep searching. Every find sheds more light on extinct creatures and helps fill in gaps in the evolutionary record. |

Heat |
Retaining heat is an ongoing job for most living things. Humans do it by turning food energy into heat through metabolism. If we get too hot, we sweat to cool off. If we get too cold, we get goose bumps and shiver. Even with an internal furnace, the body can lose heat and plunge into hypothermia. Elephants are specially adapted to beat the heat with baggy skin that helps shed heat and huge ears that circulate blood close to the skin, cooling it off. Penguins have the opposite challenge. To stay warm in their frozen habitat, they have thick feathers that they can fluff to trap a layer of insulating air. They also huddle close to each other to take advantage of group body heat. Heat is what drives the planet's weather. It all begins with the sun, which warms Earth's atmosphere. The rising of lighter, warmer air and the settling of cooler, denser air is called convection. Convection creates wind and distributes heat around the planet in conjunction with the oceans. We can also harness the sun's energy with the help of solar collectors. The Rocky Mountain Institute is a perfect example of the efficiency of solar energy. Heat is the enemy of firefighters. If they can reduce the heat of a fire, they can put it out. |

Light |
The sun is the source of light on planet Earth. It produces electromagnetic (EM) energy that travels at light speed:186,000 miles per second. Fibre optics technology has harnessed this speed to carry voice, data, and images over glass threads faster and farther than ever before. Our eyes are natural light collectors. When light enters the eyes, it reaches the retina, where special cells turn it into electrical impulses that the brain interprets. Our eyes can only see a fragment of the electromagnetic spectrum, the part called the visible spectrum. Outside the visible spectrum are other waves of varying length and frequency, from short-waved gamma rays to radio waves, which are the longest. We need special equipment to detect EM waves outside the visible spectrum. For example, radio telescopes pick up cosmic radio waves. The Hubble Space Telescope detects infrared radiation. Some creatures make their own light, called bioluminescence. Some 500 feet beneath the ocean surface, creatures use bioluminescence to help them see, avoid predators, and communicate, among other things. Jellys put on some of the best light shows in the sea, but they don't do it to look pretty. They rely on bioluminescence to survive, just as we rely on the sun's light. |

Magnetism (Jnr Secondary) |
Magnetism exists at the atomic level, as the movement of electrons creates magnetic fields. But it also exists on a universal scale, with stars and planets being the largest magnets. The force of magnetism coming from an object is its magnetic field. Earth's magnetic field, or magnetosphere, shields the planet from harmful radiation and particles carried on solar winds. In the early 1800s, it was discovered that electricity produces a magnetic field. Soon inventors learned how to generate electricity with magnets, and the generator was born. We rely on magnets to store data on computer discs and videotapes, to run electric motors, and to carry radio and television signals. Animals rely on magnetism to navigate during long migrations. It's the magnetite (lodestone) in their bodies that helps detect Earth's magnetic field and find direction. But look out. Earth's magnetic field isn't always stable. From time to time it drifts, shifts, or even reverses. Flow disturbances in Earth's molten iron core are to blame. |

Students examine diffusion, osmosis and tonicity at the cellular level, perform a diffusion experiment in gelatin, and investigate semipermeable membranes with different solutions in dialysis tubing. The exchange of energy and matter in open systems is illustrated by the physiological responses of people in physical training, by the complexity of a greenhouse ecosystem that filters waste water, and through contributions of technology such as hemodialysis. |

Motion |
Students developing solar cars have the laws of physics and motion fresh in their minds as they work to create lightweight cars that slip through the air, glide on smooth tyres, and don't run out of energy. These cars run on solar power that creates electricity to run a small motor. Unlike the cars, a rollercoaster gets going with the help of mechanical energy in the form of a motorised chain that hauls the coaster up the first big hill. From there, momentum and kinetic energy take over. Physics is also at work when skateboarders fly through the air in spectacular leaps and spins. Why doesn't the board go flying off when they jump? It's all physics. People tried to emulate the flight of birds for centuries. We finally got it right when we learned to make a wing in an airfoil shape that would provide the lift necessary to get off the ground. That same shape helps a boomerang sail away, and come back, thanks to the physics. Fish move through water as easily as we move through air. Building robotic fish helps scientists learn how they do this. |

Nuclear Energy |
Stars are natural nuclear reactors. At their cores, the intense heat and pressure cause hydrogen atoms to collide and fuse to form helium. The energy from this fusion is what fuels the star. The sun is no different. Without its nuclear energy, we wouldn't exist. People have also been able to create nuclear energy through fission. In fission, the nuclei of atoms are split, which releases great amounts of energy. The trouble lies in controlling such reactions. Dangers from uncontrolled nuclear reactions include devastation from the resulting explosions and toxic radiation. Even though nuclear science can be used for good purposes, such as energy or medicine, is carries great risks. Scientist Marie Curie helped pioneer the study of radiation, but she died of leukemia caused by its toxic properties. There is no more obvious example of the danger nuclear science poses than the mushroom cloud generated by an atomic bomb blast. There is no question that nuclear submarines are superior to diesel subs. |

Sound - Physical Science |
Sound is energy that travels in waves. Our ears are capable of receiving the waves and transmitting them through the eardrum and ear bones to the cochlea, which converts the vibrations into electrical impulses that the brain can interpret. People with hearing loss may benefit from a cochlear implant, a device that assists the ear electronically. Sound is measured in decibels: 40 decibels is normal talking volume, while 120 is the sound of a plane taking off. Scientists have found ways to get rid of noise by using sound waves to mirror the noise waves and cancel them out. You wouldn't want to cancel the sounds of a good pianist. When keys strike and vibrate strings inside a piano, the result is beautiful music. Sound is far more than music to many animals. For elephants, infrasound is a way to communicate across long distances. Bats use high-frequency sounds in echolocation. Their clicks bounce off objects, helping them navigate in darkness and find prey in the form of flying insects. Scientists suspect that bats may effectively be able to slow down time in order to process the echoes returning from their clicks. Now that's a superpower. |

States of Matter |
Everything is matter. And all matter comes in one of four states: solid, liquid, gas, or plasma. The least well-known state, plasma, occupies most of the visible universe, more than 99 percent in fact. Einstein's famous equation E=mc2 shows that matter can be converted into energy and energy into matter. Even air is matter. It exists as a gas. This can be seen when a hot-air balloon lifts off the ground. The hot air trapped inside the balloon, being less dense and lighter than the surrounding air, rises, taking the balloon with it. Superheat a gas and it becomes plasma. All stars and interstellar gases are plasma. On Earth, we can see plasma in lightning and neon lights. Sometime between 10 and 20 billion years ago, all matter and the universe itself was born out of the energy of the big bang. Scientists are trying to understand how matter formed using particle accelerators that cause atoms to collide. The energy and particles created by the collisions may offer clues to the universe's beginnings. To see the other three states of matter in action, observe the only substance that can exist in all three states, water. |

What is Scientific Inquiry? |
From the beginning of human history, natural phenomena have puzzled people and caused them to ask questions. Scientific Inquiry is about answering these questions through investigation. Scientific inquiry is not a precise set of procedure, but rather a broad approach to investigation that ranges from very open ended to very controlled investigations. Scientific Inquiry begins with questions: Why? What's going on? How is this explained? In this program, we will follow Sherlock Holmes-type investigations in the everyday and natural worlds, leading to some surprising and fun discoveries. |
