Density is _____________________________________-, chemical property, physical property, Density measures the amount of ______________ in a certain amount of __________., MATTER in a certain amount of SPACE, VOLUME in a certain amount of LIQUIDS, BALLOONS in a certain amount of GAS, How do you calculate density? , mass x volume (mass multiplied by volume), volume + mass (add volume and mass), mass / volume (mass divided by volume), mass - volume (subtract volume from mass), What is the density of an object whose mass is 20g and volume is 4cm3?, 80 g/cm3, 16 g/cm3, 5 g/cm3, 0.2 g/cm3, What is the density of an object whose mass is 5g and volume is 2cm3?, 2.5 g/cm3, 3 g/cm3, 0.4 g/cm3, 10 g/cm3, Which model shows the object with a greater density?, 1st square (blue), 2nd square (green), Objects with the same volume but different mass have _______________ density. , different , the same , Two substances with the same density might be the ____________ ___________. For example, if a spoon and ring each have a density of 10.49 g/cm³, both substances might be silver.³, different substances., the same substance., One block is silver and one block is aluminum. How can we identify which substance is silver using density?, Look at both objects, Measure mass and volume and calculate density , 1. Measure mass and volume to calculate density 2. Compare using density table, What substance is most dense? , silver (10.49 g/cm³), gold (19.3 g/cm³), aluminum (2.7 g/cm³), copper (9 g/cm³), Look at the picture. How does the density of air compare to the density of the helium-filled balloons (rising to ceiling)?, the helium balloons are less dense than the air, the helium balloons are more dense , the helium balloons have the same density as the air, How can we use density to make predictions about substances and objects in real life?, we can predict if something will go fast or slow, we can predict if something will sink or float, we can predict if something will be shiny or colorful, What is one pattern you noticed while observing density?, if a substance has more density, it will float, gases are more dense than solids, the density of a solid is always greater than 10g/mL, If a substance has more density, it will sink, Objects with lower density tend to , float, sink, Objects with higher density will, sink , float, Ice has a density of 0.93. Water has a density of 1.0. This means that ice will, float in water, sink in water.
