Grade levels: Primary (1-3)

The Big Question: “Why when I build my castle tall, it always falls down?”

Synopsis: Structures are things that we build, that make life easier, like a house or a bridge. Harrison finds out how animals have been building structures for millions of years, as well as the best way to build structures, to keep them strong and sturdy, and realizes that humans could learn a lot from beavers.

My Great Challenge: Two teams of challengers build a bridge over dino-valley with marshmallows and pasta. Who will cross first, and who will be dino-dinner?

In the Field: Harrison visits some really cool tree houses, and discovers that tension can be very relaxing.

The Big Question: “Why do we have to eat?”

Synopsis: We have to eat, because our parents make us! But seriously, Harrison learns how good, healthy food helps us grow big and strong and smart, why foods taste different between boys and girls, and which junk foods disguise themselves to pretend that they’re healthy.

My Great Challenge: How well do you know what’s in your food? Harrison surprises some challengers as they try to guess how much fat and sugar are in their favourite foods.

In the Field: Yummy?? Bacon-flavoured popcorn is on the menu, washed down with onion soda. Harrison visits a company that makes flavours and creates some weird ones to share.

The Big Question: “Why can’t everything be solar powered?”

Synopsis: Harrison takes a close look at the biggest star in our solar system – the sun, and learns that everything DOES run (at least indirectly) on solar power. Without the sun, we wouldn’t… we couldn’t, even be here!

My Great Challenge: Before watches were invented, people used the sun as a clock. Harrison puts two challengers to the test to see if they can tell the time the ancient way.

In the Field: Harrison takes a solar-powered boat cruise with its inventor.

The Big Question: “What would happen if you never cut your fingernails? Would they grow forever?”

Synopsis: Every living creature that is born grows up. But HOW do they grow, and WHY do they stop growing? Harrison finds out if girls grow faster than boys and if you can make yourself grow taller. He also uncovers the real difference between humans and other creatures, and how scientists are working to make us more like salamanders.

My Great Challenge: “Are you my Mommy?” Challengers race to match up photos of baby animals to their grown-up parents.

In the Field: Harrison sees his future! The Vancouver Film School turns Harrison into an 80-year-old man!

The Big Question: “Why isn’t magic real?”

Synopsis: Magic IS real – sort of. Nature creates its very own magic, turning gases to liquids, liquids to solids, and solids into gas. Harrison’s attic is full of magic today with instant ice cream, a flying guinea pig and a magician who makes water appear from nowhere!

My Great Challenge: Challengers have to race to stay dry while standing on a liquid. Or is it a solid?

In the Field: Harrison is airborne when he finds out how hot air balloons can fly.

The Big Question: “Why do we have families?”

Synopsis: All babies need families for their survival. Harrison investigates why babies drink so much milk and poop so much in their diapers, and why they are so cute. He also finds out why parents are so bossy.

My Great Challenge: Challengers moo-ve quickly to see how much milk they can ‘milk’ in one minute!

In the Field: Harrison visits the Calgary zoo to get the straight poop on why animal babies are different than human babies.

The Big Question: “Do plants think?”

Synopsis: Harrison discovers that plants are living things, and humans depend on them for survival not just for food and clothing, but also for the very air we breathe! Harrison investigates why flowers smell so nice and fruit tastes so good.

My Great Challenge: Team Pine Tree and Team Maple race to see who sucks the most – water that is.

In the Field: Harrison visits an organic farm to get the juice on grafting – naturally creating the strongest and best-tasting fruits and vegetables.

The Big Question: “Why is the world so important?”

Synopsis: Without a habitat, neither plants, humans nor animals could survive. Why do worms come out when it’s wet? Why don’t dolphins live on land? How can fish breathe under water? Harrison finds out about the world we live in, and all of the little worlds within it!

My Great Challenge: Team Zebra and Team Polar Bear race against the clock to match animals with their proper habitat.

In the Field: Harrison meets up a biologist, who introduces him to many types of habitats; from teensy ones on the leaf of a fern, to gigantic forest habitats, and how they’re all interconnected.

The Big Question: “What happens to stuff that goes in the trash?”

Synopsis: Garbage is stinky and gross; but Harrison finds out that even smelly garbage can be useful, and that worms make great house pets, and why that tap water you’re drinking may have been in your toilet not that long ago!

My Great Challenge: Challengers pick through the trash to figure out who lives in the household it came from.

In the Field: Harrison gives up his old television set so that he can learn how a recycling center separates and uses each of its individual parts.

The Big Question: “Why do some spiders have eight eyes?”

Synopsis: How do we see? Why CAN’T we see some things? Why do cat’s eyes glow in the dark? Harrison sheds some light on one of our five most important senses: sight! He also learns that seeing more, doesn’t necessarily mean you can see well.

My Great Challenge: Team Lion and Team Tiger search for camouflaged jelly beans.

In the Field: Harrison visits 12-year old Tait in Calgary to learn how to have fun using your other senses, when you can’t see.
