Use these science projects as a foundation and then come up with unique ideas of what to test to make it your own. The correct answer is the rock, because it has more mass. Which was more dense, the salt water or the sugar water? Try putting your bottle submarine in a sink full of salt water. Which is the most dense: water, corn syrup, or vegetable oil? Which layer was on the bottom? The denser a liquid is, the easier it is for an object to float on it. Can you figure out how much water should be in the bottle to make your "submarine" stay at a steady depth in the water? Remove the raisins with a spoon. Did adding salt and sugar to the water make the water more dense or less dense? Changing water density could cause a submarine to rise or fall unexpectedly. Why do you think they acted the way they did? Did it stay in layers? The Navy has to keep track of the salinity of seawater (how much salt is in it) because salt makes water more dense. Finally, despite the high energy density of Li-ion compared to other kinds of batteries, they are still around a hundred times less energy dense than gasoline (which contains 12,700 Wh/kg by mass or 8760 Wh/L by volume).

Learn to predict whether objects will float or sink in water based on their mass and volume. Define the relationship among mass, volume, and density. olive oil, lamp oil). If the bottle is empty (filled with air), it will float on the surface. FINDING THE DENSITY OF A LIQUID USING A HYDROMETERThe density of a liquid can also be measured using a simple device known as a hydrometer.Literally meaning "water measurer," a hydrometer is an instrument comprised of a vertical scale inside a sealed glass tube weighted at one end.It's used to measure the ratio (called specific gravity) of the density of a liquid grape to that of pure water. Pour some of the blue water into the 10 ml graduated cylinder or narrow glass. Because these liquids will have different densities, there will be different layers that are visible, sort of like being able to see ice cubes (frozen water) in room temperature water. It is meant for students to use when they are filling out their forms electronically rather than using a hard copy. vegetable oil (you can also experiment with various types of oil, i.e. State the SI units used for mass and volume. (Your answer will be more exact if you use a graduated cylinder instead of a beaker to measure the volume and weigh the liquid.). Does temperature change the density of water? This lowers the average density.). Best For: Pour some of the red (salty) water into the graduated cylinder. They won't let you down, no matter what they're up against. Add 2 teaspoons of salt to the red beaker and stir until the salt is dissolved. Please provide as much of the following information as possible: Please provide as much information as possible in your request. When the submarine is on the surface, these tanks are filled with air, which makes the average density of the sub less than the density of water. Particle density is defined as the mass of a unit volume of sediment solids. Liquid Density Science Lesson Dive! The answer is density in grams per milliliter. 5th Grade Science. and then divide that number by the volume (number of milliliters) of the liquid. The focus of this page is on the density of fluids, meaning the density of liquids and gases. This is an adaption I made for the assessment for my fifth grade students. Since water is much denser than air, this increases the average density of the submarine. This test helps you see the higher density of seawater, but a real sub doesn't have to add fresh water to the ballast tanks - it just fills up with the higher density salt water.
