Measuring Matter Tree Map To review Volume Mass

Measuring Matter Tree Map • To review Volume, Mass, and Density, create a tree map for measuring matter on a piece of notebook paper. • For each type of measurement, include a definition, ways to measure it, examples, pictures, etc.

MEASURING MATTER VOLUME MASS DENSITY

MEASURING MATTER VOLUME • How much space something takes up • Formula L x W x H • Water displacement • Examples – 5 m. L, 2 cm 3 MASS • How much matter (stuff) there is in an object • Measured on a triple beam balance • Examples – 3 g, 10 kg DENSITY • How tightly packed particles (atoms) are in a substance • Mass per unit of volume • Formula D = M/V • Examples – 1 g/m. L, 2 g/cm 3

Measuring Solid Volume 9 cm We can measure the volume of regular object using the formula length x width x height. 8 cm _____ X _____ = _____ We can measure the volume of irregular object using water displacement. Amount of H 2 O with object = ______ Amout of H 2 O without object = ______ Difference = Volume = ______ Click here for an online activity about volume.

Measuring Mass We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? _______ + _______ = ____ g Top Image: http: //www. southwestscales. com/Ohaus_Triple_Beam_750 -SO. jpg Bottom Image: http: //www. regentsprep. org/Regents/biology/units/laboratory/graphics/triplebeambalance. jpg

Density Calculations • Use the formula Density=Mass/Volume to calculate the density of the following objects! Also indicate if these objects will sink, float, or suspend in water. 1. 2. 3. 4. 5. Mass= 45 g ; Volume= 9 cm 3 Mass= 25 g; Volume= 50 m. L Mass= 60 g; Volume= 20 m. L Mass=12 g; Volume= 3 cm 3 Mass= 15 g; Volume=15 cm 3

Liquid Density Column • Place the following liquids in order with the smallest density at the top of your list, and the largest at the bottom. – Rubbing alcohol – Water – Corn syrup – Lamp oil – Dish soap – Vegetable oil
