Once upon a time, there was a boy named Jack and he had a good robo - friend, Beebot.

They also had a cow...

One day, Jack's mom told him to go to the fair and sell the cow, because they didn't have any money.

In the forest Jack and the Beebot met an old man who gave Jack a pack of beans in exchange for the cow. He said they were magic beans!!!

What would you buy except from the beans?

MAKE A SCALE and compare the weight of the beans with some other materials of your class.

CHALLENGE TIME

When the two friends returned to the village, Jack gave the magic beans to his mother and told her everything. His mother was very sad that the man tricked her boy... She didn't believe that the beans were magical, so she threw them out of the window.

But in the morning... the beans had turned into a HUGE beanstalk!

CHALLENGE TIME

Make a plant house and observe your beanstalk grow.

I wonder where it goes, said Jack...

and began to climb the beanstalk.

Up, up, up, Jack went, until he reached the top... and there was a HUGE castle sitting on the top of the clouds.

"Hey, Jack, I can't climb", said Beebot as he watched Jack up in the cloud.

CHALLENGE TIME

Build an elevator to help Beebot climb to the castle!!!

MAKE A BEEBOT MAP

In the castle, all the things were HUGE. But then Beebot spotted something...

a goose laying golden eggs!

But then there was a rumble... and a HUGE GIANT appeared! 

“FEE FA FO FUM!”

And he looked hungry!
