You're going to build the ultimate roller coaster. Okay, you're not actually going to build a life-size roller coaster that you can ride. Apparently there's this thing called safety that schools have to follow. Bummer. But you are going to design and build a model roller coaster. It needs to be the kind of roller coaster someone would actually enjoy. Think about this ultimate roller coaster. Consider your ideal audience. Will it be a gentler ride for younger kids or will it be a terrifying ride for adventure seekers? How do you want people to feel? You want them to be scared, nervous, excited, calm? Maybe a mix of all of those emotions. What kind of theme will it have? See every roller coaster has a theme. It might be a mountain theme or a space theme or a pop culture theme. So create a theme for your roller coaster. Decide on the features of your ride. Will it have a huge drop? A loop? A corkscrew turn? Think of the physics and mechanics of your ride. How will you keep your coaster going from start to finish without stopping? Your items will include duct tape, paper, cardboard, a marble, plastic straws, and popsicle sticks. Don't forget to experiment and make tons of glorious mistakes. Ultimately your design is going to be awesome because it's yours and it's coming from your creative mind.
