The Big Question: “Is snow really white?” DESCRIPTION: With the help of an animal expert, Harrison finds out how chameleons change color and viewers find out if they’re lion sighted in a color blindness test. A physicist explains why there are some colors that we can’t see, and viewers get a bug’s eye view of the world in order to discover how bugs see things that are invisible to humans! Harrison carries out an experiment to see if kids will turn their noses up at a batch of blue scrambled eggs! My Great Challenge: In this week’s challenge, viewers have to make colors - with other colors! In the Field: Harrison takes to the skies in an Air Force search and rescue helicopter for a high-flying experiment to find out why some colours attract our eye more than others.

The Big Question: “Are mosquitoes good for anything, or are they just annoying?” Description: Harrison visits an entomologist who explains to him how insects that eat insects can replace the poison farmers use to keep bad bugs away from their crops. Harrison is joined by a biologist who puts on a fascinating show and tell with all kinds of live bugs. He then puts school kids to the test by asking them to eat everyday products that most of us don’t realize contain…you guessed it…bugs! And viewers find out that a lot of household products are made using insects (everything from carpets to lipstick!). My Great Challenge: Harrison sets up a face-off between Team Bee and Team Butterfly to see who the best pollinator is! In the Field: Our roving correspondent Sidney visits a food scientist and a chef who cook her up a tasty bug stir-fry!

The Big Question: “Why does the moon follow us?” Synopsis: Harrison investigates intriguing facts about the moon, like why people think wolves howl at the moon (they don’t), whether the moon really turns people into werewolves, who the first men on the moon were and why the moon appears to follow us. Viewers at home test out their jumping skills as Harrison demonstrates where we’d be without gravity! My Great Challenge: Using nothing more than a light, their wits, and funny headgear, challengers must figure out why the moon is sometimes full and why at times, it disappears! In the Field: Harrison goes to…the Moon! Okay, maybe not the actual moon, but a simulated moonscape created by the Space Agency, where astronauts practice their extraterrestrial techniques and test out new equipment. There, a lunar geologist provides the answers to more kid questions, explaining how the Moon was formed and why there are craters.

The Big Question: “Can a horse and a pig communicate?” Harrison is visited by a very special guest - a parrot - and he tries to figure out if he can understand what it’s saying! Meanwhile, viewers get to test out their ability to communicate with dogs. Harrison also discovers why humans speak so many different languages.

In the Field: Harrison sets off to the Sea Aquarium to see if dolphins can understand sign language.

The Big Question: “Why do bats sleep upside down?” Description: Harrison sets off on an investigation of such sleep phenomena as yawning, snoring, and sleepwalking. Along the way he shows kids how to make other people yawn and how to make it seem like they are fast asleep (with fake snoring!). Viewers get to find out what causes nightmares and how to make bad dreams go away. My Great Challenge: The challengers must have slept in today….there is no great challenge in this episode. In the Field: Harrison explores a sleep lab where he is hooked up to an EEG machine that monitors his brainwaves.

The Big Question: “Why can’t we fly?” Synopsis: With the aid of a wind-tunnel and a four-time national radio-controlled airplane champ, Harrison takes to the school yard to discover why some things fly better than others and viewers find out what it really takes to leave the ground. My Great Challenge: Challengers take part in a paper airplane experiment to see who can make the best wing. In the Field: Harrison goes out into the field with a bird trainer to get a close up look at two of the best flyers in the animal world - an owl and a falcon.

The Big Question: “Why does my hair stick to my chair?” Description: A physicist visits Harrison to explain how electricity is generated, and teaches us how it can be conserved. Viewers can take part in a fun experiment to see electricity at work in their own bodies. My Great Challenge: Kids race to complete a circuit! But before they can do anything they must find a way to transfer power over a short distance, from a battery to a light bulb, by determining what materials conduct electricity. In the Field: Harrison goes to the Sea Aquarium to visit a marine expert and some willing aquatic life to explore why electric eels don’t electrocute themselves and how sharks can detect our presence because of electricity!

The Big Question: “How come weather changes?” Description: Harrison is visited by a real-life television weatherman who shows us how he predicts the weather. Viewers will learn how to gauge wind strength and direction from famous storm chaser George Kourounis as Harrison talks to him live from a location in America’s Tornado Alley. My Great Challenge: Harrison and the weatherman create an in-studio challenge where kids try their hand at presenting a weather forecast in front of a green screen. In the Field: Terrible storms must be in the area today…there is no In the Field segment in this episode.

The Big Question: “Why do people hate the sound of fingernails on a chalkboard?” Harrison is joined by rapper and musician Kid Koala, a special guest canine, and opera singer Lindsay Michael. Individually, these experts help us find out about the delicate mechanisms that help us hear. The special guest canine helps Harrison figure out whether dog whistles really are silent, and Lindsay Michael tests out whether a person can actually shatter a crystal glass with their voice. Viewers at home find out if they have bat-like hearing! My Great Challenge: Kids must compete to see who can give our opera singer goose bumps by figuring out which material to scratch together to make the shriekiest sounds! In the Field: Harrison travels to the sea aquarium and discovers that certain fish may use sound to communicate – by farting at each other!

The Big Question: “Do dinosaurs eat people?” Harrison sets out to explore why it is that some animals evolve to be big, while others evolve to be small. He is visited by a miniature horse and its foal who help him find out why animals are bred to be different sizes. Viewers are encouraged to test their own ability to make themselves seem as big as possible! My Great Challenge: Challengers take part in a competitive (and tasty!) experiment to find out whether it’s an advantage for a predator to eat big or small prey (or to be big or small prey). In the Field: Harrison takes a trip to the aquarium to visit some of the biggest animals of all - whales!

The Big Question: “Why will things change when you get older?” An anthropologist and real-life expert in prehistoric tool-making teaches Harrison how to make Neanderthal knife blades and to paint like a “cave kid”. Harrison invites kids at home to join him in making simple machines – a wedge, an inclined plane, and a lever - using nothing more than a sheet of paper. My Great Challenge: Contestants must figure out how to adjust a simple catapult in order to see who can throw a toy monkey the furthest. In the Field: Harrison takes on an assembly line robot to see which of them can put a car together the fastest.

he Big Question: “How does your nose get runny?” Harrison is visited by a microbiologist who helps him take a close look at an invisible world and figure out how to stop viruses from hurting us.

She meets an adventurer who goes down inside active volcanoes and gets a live demonstration of how his flame-proof suit works when one of his friends sprays him with liquid fire!

The Big Question: “Why do we have hair?” Synopsis: In a search to learn about the origins of hair, Harrison finds out about the cultural implications of different hairstyles – from mohawks to baldness. My Great Challenge: Harrison’s guest challengers must identify different types of animals from close-ups of their fur. In the Field: Harrison visits a hairstylist and finds out why our hair turns grey and how amazingly strong it is. He also visits an anthropologist with a big skull collection who explains to him why the gradual loss of our primordial “fur” helped shape us into the type of animal that humans are today.

The Big Question: “Do sea monsters really exist?” Finding out how crucial the ocean is to our ecosystem, Harrison discovers that although monsters might get the attention, it’s the little things that count. For example, a tiny creature called phytoplankton creates half of the oxygen that we breathe. Using potatoes, a marine biologist helps Harrison figure out how fish drink! My Great Challenge: Harrison hosts a challenge for his guests to figure out how to make plasticine float… then, with musical accompaniment, he reveals the identity of “the monster in the sea”. In the Field: Harrison visits the shark tank of a sea aquarium to find out if it’s true that sharks die if they fall asleep.
