    The Day Paratroopers Made 'Air Strikes' in Year 3

    • Yew Chung students, not only study two languages and cultures, but also experience many types of scientific activity. This time Year 3SC had the chance to prove their scientific knowledge.

      The students have previously studied various machines that can fly, and how they are affected by gravity, air buoyancy and the pull of the engine. In this week’s class we focused on air resistance. With the support of two teachers the children made a parachute and held a parachute competition.

      After receiving instruction on the structure of parachutes, the children began to create their own. First we cut plastic bags into shape to make the parachute. Then we tied strings to each corner and the children experimented with different styles. Could we make the parachute fall slowly to the ground? To be safe we didn’t use real children under the parachutes, but instead used coloring pencils to substitute as paratroopers!

      Our ‘battlefield’ was the playground. Children threw their parachute into the air to see whose would stay in the air the longest! After many repeated throws of our parachutes, we not only had fun, but also discovered that the parachutes that could create the greater air resistance by increasing the surface area of the parachute would stay in the air the longest.

      This type of practical first-hand science activity provided a happy atmosphere, allowing us to question and problem-solve reasons behind scientific knowledge we have studied, as well as cultivating a curiosity and interest in science. We were happy to see our future scientists shining brightly!
