Entry Events
Events that will be used to introduce the project to studentsScience in Action: Rocket Assembly Race
Kick off the project with a rocket assembly race. Students will be given all necessary components to build a basic water rocket and must work in teams to assemble and launch their creations. This immediate hands-on experience will harness their natural curiosity about physics and engineering, challenging them to think critically about force and motion.MythBusters Challenge: Rocket Edition
Start the project by presenting students with popular myths about rockets and propulsion (e.g., 'A heavier rocket travels further'). Encourage students to design experiments using their water rockets to test these myths, promoting critical thinking and authentic scientific inquiry.The Great Height Challenge: Real-Time Data Collection
Initiate the project with a live water rocket launch and engage students in measuring and recording its peak height, speed, and distance. This involves real-time data collection and lays the groundwork for exploring concepts like force, motion, and energy transformations, while directly connecting to their personal experiences and interests in outdoor activities.Portfolio Activities
