Grade levels: Primary (1-3)

The Big Question: “When will I have my own personal robot?”

Synopsis: Harrison and a cheeky humanoid robot named Nao 1337 compete to see whether humans are better than robots. Along the way, Harrison discovers robots that’ll do everything from vacuum your room to play chess against grandmasters.

My Great Challenge: Kids from a champion robotics club strut their stuff as they compete to see who has the best robot.

In the Field: Harrison visits a tetraplegic who can do amazing things with her robotic arms.

The Big Question: “Will water ever go extinct?”

Synopsis: Harrison’s water is shut off today because of a water main break, so he’s extra interested in how water is formed, and how we can conserve it.

My Great Challenge: In some countries, kids have to carry water from a well instead of getting it from a sink. Our challengers compete to see how much of their daily water they can carry before time’s up.

In the Field: Harrison goes to fire-fighter training, where he puts out real fires with water.

The Big Question: “Do dragons exist?”

Synopsis: To find out where dragon legends could have come from, Harrison goes on a quest to find the biggest, dragon-iest reptiles in the world.

My Great Challenge: How can snakes move without legs? To find out, challengers squeeze into “snake suits,” then race to wriggle their way to the finish line.

In the Field: At a reptile zoo, Harrison handles real-life crocodiles and meets a cousin of the fearsome Komodo dragon.

The Big Question: “Can kids go into space?”

Synopsis: Harrison wants to go to space, but first he’ll have to learn how to float in zero gravity, sleep “standing up,” and figure out how a rocket works. Fortunately, he knows some real astronauts who can help him out.

My Great Challenge: Challengers in a “zero gravity” rig compete to see who can fix a broken satellite the fastest.

In the Field: At the Canadian Space Agency, Harrison samples astronaut food and learns how to “catch” a delivery of space groceries with the Canadarm2 robotic arm.

Synopsis: Harrison’s little sister decided to “improve” Harrison’s show by mixing up all the clips – and adding sparkly dancing unicorns. Now Harrison has to put his show clips back in order. As he goes through them, he notices that his sister picked clips that show how weird and surprising science is. Maybe she arranged them well after all (except for the sparkly unicorns, of course!).

Synopsis: As Harrison prepares for his school science fair, he realizes that science is all around us. Highlights from this past season, including questions about the sun, plants, teeth and spiders, help prove his point.

The Big Question: “How come humans don’t have scales?”

Synopsis: Harrison investigates the stuff that holds us in: skin. With help from a special-effects make-up artist, he finds out the science behind scabs and bruises, and even learns how to make cool fish-monster scales.

My Great Challenge: Are parts of our skin more sensitive than others? Blindfolded challengers have to identify mystery objects rubbed against their foot, leg, and hands.

In the Field: Harrison goes to the beach with a skin scientist to test how sunscreen can protect UV-sensitive Frisbees from turning purple.

The Big Question: “How can you break things with a karate chop?”

Synopsis: Harrison is on a quest to break a karate board with his bare hand, but first he’ll need some expert help – from a materials engineer and a karate master – to understand the science behind why things break. Hiii-yaaa!

My Great Challenge: Kids compete in an egg-drop challenge, to see what kind of padding materials can protect a raw egg when it’s dropped from a great height.

In the Field: Harrison has a dynamite time at a rock quarry when an expert helps him blow up rocks with real explosives!

The Big Question: “How do flowers poop?”

Synopsis: Hold on to your nose! Harrison decides to do a show about, well, you know. He’s visited by a paleontologist who brings million-year-old fossils of dinosaur poop.

My Great Challenge: Challengers have to pick apart fake animal poop to find bones, berries, and grass, and then guess whether the animal who made the poop was an herbivore, carnivore, or omnivore.

In the Field: Harrison and an animal biologist collect real animal poop in the woods, and then examine it in the lab. P-U!
