Scientific investigations in Year 5
This week, our Year 5 explorers took to the "skies" to investigate one of the most invisible yet powerful forces on Earth: Air Resistance . The Question : Does the size of a parachute change how fast an object falls to the ground? Before we started, the class made their hypotheses . Most of our scientists predicted that the larger parachute would be slower, but they needed the data to prove it! The children made their own parachutes of contrasting sizes and attached a paper clip to them to test them. The results were clear! The large tissue paper parachute consistently drifted slowly to the ground, while the small parachute plummeted much faster. Why did this happen? It all comes down to Surface Area . As the paperclip pulls the parachute down due to gravity , the tissue paper has to push its way through the air. Large Surface Area: The big parachute hits more air particles as it falls. This creates more air resistance, which pushes up against the parachute and slows the ...
