This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park. Groups of learners will compare two water slides by measuring each ride’s length and duration to calculate the speed. They will also attempt to trace a clean line through a maze while riding down the slides to measure which is the wildest. Relates to linked video, DragonflyTV: Waterslides.
