The Expanding Universe: A Balloon Experiment
Investigating the expansion of the universe using a balloon, marker, ruler, and string. Measuring distances on a curved surface and analyzing the relationship between dot distances and the expansion of the earth and universe.
00:00:03 Investigate the Big Bang Theory by testing the expansion of the universe using a balloon, marker, ruler, string, and assistance. Blow up balloon slightly, mark it with dots and letters, then pause.
🔍 This lab investigates the Big Bang Theory and tests if the universe is expanding.
⚗️ To conduct the lab, you need a marker, a balloon, a ruler, and a piece of string.
🔢 Blow up the balloon a little bit, mark four dots on it, and label them with the letters H, A, B, and C.
00:01:15 Learn how to measure distances on a curved surface using a string and ruler. Use the HAB and C dots on a balloon to practice.
🔢 Measure the distances between points on a curved surface using a string and ruler.
📝 Record the distances in centimeters on paper.
💨 Inflate the balloon after completing the measurements.
00:02:17 Inflate and measure a balloon multiple times using a ruler, recording distances in centimeters.
📏 Measure the distance from H to F and record it in centimeters on paper.
🎈 Inflate the balloon three times and measure the distance from H to A each time.
✏️ Record all measurements on paper in centimeters.
00:03:19 Investigating the relationship between the distance between dots on a balloon and the expansion of the earth and the universe.
📏 The distance between the dots changed as the balloon increased in size.
🌌 This change in distance provides insights into the expansion or shrinking of the earth and the universe.
🌍 The dots closer to each other changed more than the ones further away.
