Interact with blocks of different materials, including a custom option by modifying their mass and volume, to explore the effect on the density and discover the conditions for sinking or floating in water. Play detective to determine the material of each block by comparing its density with the values in the table.
Density of Liquids. How does density affect how water, vegetable oil, and dish soap layers in a container? Prediction: How do you think the liquids will layer when poured in a container? Materials: 50 mL of each liquid: water, vegetable oil, and dish soap tall, clear cylindrical container graduated cylinder scale that measures in grams. Procedure:
Density – the degree of compactness of a material; defined as the ratio of mass to volume, often reported in terms of g/mL or g/cm3. Graduated Cylinder – a narrow cylinder with graduations to measure volume. Homogeneous – having uniform composition and properties throughout. Mean – the arithmetic average of a set of values.
Density is a measure of the amount of mass in a certain volume. This physical property is often used to identify and classify substances. It is usually expressed in grams per cubic centimeters, g/cm3, or grams per milliliter, g/mL. The chart on the right lists the densities of some common materials.
29 kwi 2024 · Gather materials and make copies of the Density Column Lab – Part 2 Worksheet. Break the Popsicle sticks and crayons into three or four equally sized pieces so that the pieces fit into graduated cylinders. At each lab station, place a marble, Popsicle stick piece, crayon piece and pasta noodle.
Use the options at the top right to complete the Same Mass, Same Volume and Same DensityData Tables below. For each section, record and calculate the mass, volume and densities of the four blocks. Hint- Make sure you find the volume of the ENTIRE object!
