How Height Affects Speed

This 250-word reading passage introduces fourth-grade students to the relationship between height and speed, aligned with NGSS standard 4-PS3-1. Students discover how objects released from higher positions move faster when they reach the bottom, using familiar examples like ramps and slides. The passage explains the connection between potential energy (stored energy based on position) and kinetic energy (energy of motion), helping students understand that more height means more stored energy, which converts into greater speed. Through real-world examples and simple explanations, students build foundational knowledge about energy transfer and transformation. The passage includes audio integration for accessibility, bolded vocabulary terms with clear definitions, and age-appropriate language suitable for fourth-grade readers. Accompanying activities include multiple-choice comprehension questions, writing prompts that require students to explain and apply concepts, and graphic organizers that help visualize cause-and-effect relationships and compare different scenarios. A simplified differentiated version supports struggling readers while maintaining the same core science concepts. Spanish translations of both versions ensure accessibility for English language learners. This comprehensive resource prepares students for hands-on investigations and class discussions about energy, motion, and the scientific principle that higher starting positions result in faster speeds at the bottom.
