ROLLER COASTER ENGINEERS!
Today YOU are the engineer 🛠️
What makes a roller coaster SO FUN?
Shout out your favorite! 📣
Here's the BIG SECRET...
Roller coasters only have a motor for the FIRST HILL.
After that...
GRAVITY does EVERYTHING! 🌍
Potential Energy
= STORED-UP energy
When you lift the marble HIGH, you're saving up energy.
Like stretching a rubber band! 🪀
Higher start = MORE energy saved up!
Kinetic Energy
= MOVING energy
The second you let go... ZOOM! 🏎️
Stored energy turns into SPEED!
Higher start = FASTER marble!
The GOLDEN RULE
Your marble can NEVER go higher than where it STARTED!
Why? Every bump and turn STEALS a little energy. ⚡
Try to break this rule. We dare you. 😏
FRICTION = the energy thief 🦹♀️
Every time the marble rubs, scrapes, or bangs...
A little energy turns into HEAT and disappears!
Think Like an ENGINEER 🧠
Build → Test → Fix → REPEAT
Your marble WILL fall off. That's not failing — that's the track telling you what to fix!
Use what you've GOT
Real engineers don't get unlimited stuff. Limits make you CREATIVE!
BUILD A MARBLE COASTER!
Marble travels 5+ seconds ⏱️
Includes a turn or curve 🌀
Lands in a paper cup 🥤
