What does popping bubble wrap have to do with science? Actually, it demonstrates an important scientific law, called Boyle’s law. Like other laws in science, this law describes what always happens under certain conditions. Boyle’s law is one of three well-known gas laws, which state the relationships among temperature, volume, and pressure of gases. (The other two gas laws are Charles’ law and Amontons’ law.) According to Boyle’s law , if the temperature of a gas is held constant, then decreasing the volume of the gas increases its pressure—and vice versa. That’s what happens when you squeeze the bubbles of bubble wrap. You decrease the bubbles' volume, so the air pressure inside the bubbles increases until they pop.
Beth was excited to be at the circus. She jumped up and down when her mother said she could get a balloon animal. When the clown handed her a dog shaped balloon she smiled and hugged it tight. Suddenly there was a load pop and her dog was in pieces.
Was the air pressurer in the balloon increasing or decreasing when Beth squeezed it
