![]() ![]() Did you know that it’s easier to float in the ocean than in a pool? That’s because ocean water is denser than pool water, due to the high salt concentration in the ocean. Density is super important to consider when building things like ships or submarines. Density helps us predict whether something will sink or float.If they don’t, start a discussion using the questions below! Bring on the Science!ĭuring this activity, natural questions may come up. NOTE: Make sure the sugar is completely dissolved before attempting to layer the colors-it’s what creates the difference in density of each color. Under these conditions, the exact density of water is 999.972 kg/m3. Still using the baster, transfer half the green water into the rainbow glass. It is generally accepted that the density of water is 1000 kg/m 3, 1000 g/l or 1 g/ml, but do we often think at what temperature these data were obtained The maximum density of water is reached at a temperature of 3.84.2C. This is where you’ll make your rainbow.Ĥ. Use the turkey baster to transfer about half of the blue water into the empty glass. Without the sugar fully incorporated into the water, you’ll have trouble getting the colors to separate. Heat up your water if it’s not working-five to 10 seconds in the microwave and an extra stirring session should help.ģ. NOTE: Stirring to completely dissolve the sugar is very important. Glass 4: Add 4 tablespoons of sugar and 2 drops of blue food coloring and stir. Water - Density Viscosity Specific Weight, Dynamic and Kinematic Viscosity of Water in Imperial Units (BG units). Glass 3: Add 3 tablespoons of sugar and 2 drops of green food coloring and stir. Starting on the right, we see that 20 degree Celsius water is less dense than. Glass 2: Add 2 tablespoons of sugar and 2 drops of yellow food coloring. The red line shows how the density of water changes as the temperature changes. Stir vigorously to completely dissolve the sugar. Glass 1: Add 1 tablespoon of sugar and 2 drops of red food coloring. Each color will have a different amount of sugar in it. Add sugar and food coloring to the water. Fill four drinking glasses with 1/4 cup of warm water each.Ģ. How to Conduct the Sugar Water Density Experimentġ. All you need are a few common household items. In Imperial or US customary measurement system, the density is equal to 62.4 pound per cubic foot lb/ft, or 0.58 ounce per cubic inch oz/inch. density of water is equal to 1 000 kg/m at 25C (77F or 298.15K) at standard atmospheric pressure. In this sugar water density experiment, we will change the density of different colored water solutions so that they stay separated from each other. Water weighs 1 gram per cubic centimeter or 1 000 kilogram per cubic meter, i.e. The more sugar you add, the denser the solution. When you mix sugar with water, the sugar molecules occupy the space between the water molecules, making the solution more tightly packed (denser). An easy way to change water density is with sugar. Water can have different densities as well. For example, oil molecules are packed less tightly than water molecules, making oil less dense than water and causing it to float on top when the two are combined. What happens when you combine blue, green, yellow, and red water in a single glass? Brown, right? Not necessarily! Make this mesmerizing rainbow in a glass by experimenting with water density.ĭensity measures the amount of mass in a particular space.
