The Expanding Universe: A Balloon Experiment

🔍 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.

🔢 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.

📏 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.

📏 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.
