Preface:

In today’s era where more and more emphasis is placed on children’s education, scientific enlightenment education has gradually become an important topic in the field of education. More and more teachers and parents are focusing on developing children’s scientific literacy from an early age, enabling them to establish good character and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child time together, enhance parent-child relationships. The moments we spend with our children are free from phones, iPads, or televisions—only joy, interaction, and communication. It helps children develop the ability to solve problems on their own. When faced with challenges, children must first see, experience, and resolve them themselves, just as parents and teachers do during craft activities. It also stimulates children’s imagination—in their world, cars can fly in the sky, and the sun can be green... Playing DIY crafts allows children to develop hands-on skills by using various tools, giving their hands ample opportunity to move. Pencils, paints, scissors, hot melt glue, tape—they all challenge children to try, and to some extent, help develop different skills. It boosts children’s confidence. During craft activities, we explore countless possibilities and experience many failures, but we always succeed, which in turn enhances their confidence. It helps cultivate children’s focus. As they explore various tools and crafts, they remain very focused; without external distractions, they can continue exploring indefinitely.

Experimental Objectives:

For water rocket use: launcher: 56*34 mm; double-layer rubber ring for threaded nozzle: 40 MM*33 MM; bottle with a 28 mm diameter nozzle.

A water rocket is a toy designed using the ratio of mass and air pressure, and it is also one of the famous examples used in physics education. It can help cultivate students' interest in physics learning, and the physical principles involved are an important foundation for understanding mechanics in physics.
Water rockets, also known as pneumatic water spray rockets or water propelled rockets, are made using discarded beverage bottles to create the power chamber, body, nose cone, tail fins, and parachute.
