Science
The boy examined three different types of rockets and discovered that they are propelled by reaction engines that expel hot gases or plasma. He connected this observation to Newton’s third law of motion, stating that every action—such as the high‑speed ejection of gas—produces an equal and opposite reaction that pushes the rocket upward. He also identified the four states of matter—solid, liquid, gas, and plasma—and explained how the transition of fuel into hot gases and plasma creates the thrust needed for launch.
Tips
To deepen his grasp, set up a simple water‑rocket experiment so he can see action‑reaction in real time, then record measurements to discuss force and motion. Introduce a short research project on how scientists use plasma in modern propulsion, encouraging him to create a poster that links each state of matter to a real‑world example. Invite him to write a short story from the perspective of a rocket, weaving scientific facts into the narrative to strengthen both content knowledge and language skills. Finally, use a digital simulation (such as PhET’s "Rocket Simulator") to let him tweak variables like fuel mass and nozzle size and observe the effects on launch height.
