How do makers make sure every basketball bounces the same?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do makers make sure every basketball bounces the same?

The Big Idea

Every basketball in a game bounces the same! How do makers check? Let's test.

Rules

Step one: Rules. Sports groups set rules for how big, how heavy, and how bouncy a ball must be. Factories have to follow them.

Drop Test

Step two: Drop Test. Factories test balls by dropping them from a set height onto a hard floor and measuring how high they bounce. They check air pressure, size, and shape too.

Fair Games

Step three: Fair Games. A ball that fails goes back. This testing keeps games fair because every ball acts the same.

A Closer Look

Let's take a closer look! Set height. Measured. Checked. Round.

Quick Facts

Quick facts! A regulation basketball should bounce back to about two-thirds of its drop height. Rules set sizes. Drop from set height. Keeps games fair.

Think Like a Scientist

Now, think like a scientist! Find two balls. Drop them from the same height. Measure how high each bounces. Write it down. Do they match?

Outro

Sports groups set rules for ball size, weight, and bounce. Factories drop balls from a set height and measure the bounce, plus air pressure, size, and shape. Balls that fail go back, which keeps games fair. So when you play, you can trust that the ball will bounce just the way it should, game after game. Science is amazing! Keep asking questions! The more you look around, the more wonders you will find, so keep your eyes open! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download!
