Part 1: Introducing Universal Theme of Systems

So what could you do with a Universal Theme of Systems? Well, here’s an introduction that will get your students’ brains sweating.

Part 2: Systems: Pull One Thread

A sweater is really one long thread looped a thousand times. Pull the right loose end and the whole thing unravels in seconds. So is a system like that strong or fragile?

A clock is a system. So is a rainforest. So is your school. Once you see systems inside systems, you can’t unsee it.

Part 5: Systems: Watch vs. Forest

A watch stops dead if one tiny gear breaks. A forest can lose a whole species and barely notice. Which is the better-built system — the one where every part matters, or the one where no part is essential?

Part 6: Systems: The Thermostat

Part 7: Systems: Grandpa’s Axe

Grandpa’s axe broke, so he put on a new head. Years later the handle cracked, so he replaced that too. Now no original piece is left. Is it still the same axe, or a new one?
