Class discussion after watching the video clip:
What does the driver need to be able to do?
What will happen to the driver if they get caught?
Read the dialogue from the video in pairs:
Farms are pretty.
They sure are. Green growing things are beautiful to look at. And they're important, too.
What's that machine?
It's a disc harrow. They're making the field ready for a new crop.
How?
The harrow turns the soil over and breaks it up. So when they plant the new seeds, the dirt is nice and loose, and the roots can dig into it. It also makes it easier for water to soak in.
Cool.
Watch the video again. Did you understand it better now? Answer the questions:
What is the machine in the video? What does it do?
How does the disc harrow prepare the field?
What happens to the soil when the disc harrow turns it over?
Why is it important for the soil to be loose when planting new seeds?
Why is it good for water to soak into the soil easily?
What is your favorite green growing thing and why?
