Vacate the Cave!
Standards: NGSS.SCIENCE MS-ESS2-2, MS-ESS3-3
You're exploring a cave with your friends when suddenly your flashlight starts to flicker. It's almost out of batteries, and there is no way you'll find your way out in complete darkness. You decide to use the flashlight on your phone, but there is only 5% battery power remaining! Maybe you shouldn't have taken so many selfies with the stalactites. Suddenly, you see something shiny. It's a BreakoutEDU box marked, "Supplies." Wow, that's convenient! You have 10 minutes to open the box before your batteries run out.
