An elementary school student is building a model rocket for a science fair. Each stage of the rocket increases its height by 50%. If the initial stage height is 4 meters, what will the height be after 5 stages?

Building a Model Rocket for a Science Fair: How Height Grows by 50% Each Stage Bringing science to life through hands-on experiments is one of the most exciting parts of school, especially during science fairs. Many young inventors turn to model rockets to explore physics, engineering, and proportional growth—especially when each stage increases the rocket’s height by a compelling 50%. If you’re an elementary school student building your own model rocket, understanding how height increases stage by stage can deepen your curiosity and make your project even more impressive. ### How Does Height Grow with Each Stage? In this project, each stage instantly boosts the rocket’s height by 50%. This means the new height is 1.5 times the previous stage’s height. Starting at an initial height of 4 meters, the rocket’s growth follows an exponential pattern—doubling in a multiplicative sense with each stage.
