Engineers To The Rescue Refill **CLEARANCE**

You’re on a camping trip with your Girl Scout troop at Yellowstone National Park. Your first day at Yellowstone was incredible; you hiked all morning, saw Old Faithful in the afternoon,and sang campfire songs under the stars. You also visited the Visitor’s Center, picked up a brochure, and met a park ranger. You learned that Yellowstone is situated on a bed of lava, and that minor earthquakes are frequent. Although scientists didn’t predict it, there was an earthquake which shook your tents for two minutes overnight. Unfortunately, this natural disaster has broken the water pumps, and disrupted the generators in the park. To make matters worse, your cell phone battery is dead and you can’t call for help. The worst part is your animal-proof food box fell down a ravine. You’re hungry! The good news is that your troop is safe, everyone is in good spirits, and women from the Society of Women Engineers (SWE) are on a leadership retreat—they are your neighbors at the campground! They have a lot of knowledge to offer as you rebuild your campground. Check out the backs of the career cards to hear from the SWE team. As a troop, you must develop a wind-powered crank to lift your food box, create a water filter to clean water for drinking, build a shelter to withstand any aftershocks, and design a car prototype that will make it over the terrain to deliver your message to potential rescuers. You’ve got common sense, science smarts, and a group of skilled engineers to help you.
