The Floating Bowling Ball

IntroductionWhy perform a little matters drift at the same time as others sink? Capture your college students’ interest with thisdesirable demonstration of a bowling ball floating in water!

Safety PrecautionsGently vicinity the bowling balls withinside the water. For heavier bowling balls, you may should vicinity them withinside the water lightly and slowly decreasethem to the lowest of the aquarium. Not doing so ought to bring about the aquarium glass breaking. Follow all laboratory protection guidelines.Preparation1. Fill the aquarium or bath 2/three complete with water.2. Gently vicinity the eight-pound bowling ball withinside the aquarium.DisposalThe aquarium and bowling balls need to be stored for destiny demonstrations.Tips• This demonstration is a extremely good discrepant occasion for college students to look as they stroll into the classroom.• Another choice is first of all simplest water withinside the tank. Have college students are expecting which bowling balls will drift or sink from a number of bowling balls with specific weights (bowling balls 12 kilos and lighter will drift).• An extension of this pastime will be to check extra family gadgets to look if the items will sink or drift. Extend the pastime and feature college students calculate the densities of the items earlier than putting them withinside the tank.• The following kits may be used to similarly discover density:– Salting Out—Density Bottle Demonstration Kit (Flinn Catalog No. AP7931)– Measurement Challenge—A Density Laboratory (Flinn Catalog No. AP5939)– Density Cube Set (Flinn Catalog No. AP6058)

DiscussionDensity is a feature belongings of matter, and substances may be recognized with the aid of using their density. Density is described because the mass of asubstance in step with extent (Equation 1).MassDensity = ———— Equation 1 VolumeDensity is usually expressed as g/cm3 or g/mL. The density of natural water is 1.00 g/cm3 at 20 °C. Objects with a densitymore than 1.00 g/cm3 will sink in natural water. Objects with a density much less than 1.00 g/cm3 will drift in natural water.Bowling balls are the identical extent however can range in weight. The circumference of a bowling ball is 27 inches. While the bowlingballs are the identical size, they've specific hundreds and are made of various substances. The decrease the mass, the smaller the density. When the density is much less than 1.00 g/mL, the bowling ball will drift.To decide if a bowling ball will drift or sink, the density may be calculated. First, the radius have to be calculated from the circumference (Equation 2) and inches are modified to centimeters (1 inch = 2.fifty four cm):27 inches = 68.fifty eight cmCircumference = 2πr Equation 268.fifty eight = 2πrr = 10.nine cmThen the extent of the bowling ball may be calculated the use of Equation three.V = 4/3πr three Equation threeV = 4/3π(10.nine)threeV = 5446.eight cm3Lastly, the load in kilos wishes to be transformed to grams earlier than calculating the density (1 pound = 453.6 grams).MassDensity = ————VolumeA pattern calculation for an eight-lb bowling ball is given below.Density = (eight lb × 453.6 g/lb)/(5446.eight cm3) = 0.sixty seven g/cm3Since the density of the eight-lb bowling ball is much less than the density of water, the ball floats.Materials for The Floating Bowling Ball are to be had from Flinn Scientific, Inc.Catalog No. DescriptionFB0212 Aquarium, All-Glass®, 20 gallon (24″ × 12″ × 16″)AP6058 Density Cube SetAP5939 Measurement Challenge—A Density Laboratory KitAP7931 Salting Out—Density Bottle Demonstration KitConsult your Flinn Scientific Catalog/Reference Manual for modern prices.
