Measurement By Mrs. S. Deringer

Measurement began from.....

Why Metric????

Volume is... a measure of the amount of space an object takes up.

How do you measure Volume?

You must look at the meniscus The curve of the liquid. 50

How do you measure Volume of a solid ? To measure the volume of a solid. Multiply : Length X Width X Height length HEIGHTHEIGHT width

Volume of an irregular shaped solid Water level 51.0 mL 50.0 mL 1.0 cm mL = 1.0 cm 3

1.On the lines below explain what the science student did incorrectly. What should she have done? 2. Now compute the right answer. Remember to use the correct unit of measure. The mass of mL is. 3. The mass of an empty beaker is g. The mass of this same beaker filled with water is g. Therefore, the mass of the water must be 4. The mass of an empty beaker is g. The mass of this same beaker filled with water is g. Therefore, the mass of the water must be 5. The volume of of block whose sides measure; height 6.7 cm, length 3.0 cm and width 5.2 cm is She added. She should have subtracted. 20.0g 149.0g g cm3 Page 1 Measurement Review Sheet Answers

6. What the science student did incorrectly was 7. The science student should have He didn’t set the riders to the sum of the masses Set the riders to 13.0g (10.0g = 3.0g) 1.Set riders to 37.0 g (27.0g g) 2.Pour the salt into the container until the pointer returns to A scientist needs 50.0 grams of sand. The container she is using has a mass of 3.0 grams. What should the scientist set the riders to on the triple beam balance? 10. A scientist needs 40.0 grams of sand. The container he is using has a mass of 27.0 grams. What should the scientist set the riders to on the triple beam balance? 11. A scientist needs 0.5 grams of salt. The container she is using has a mass of 7.0 grams. What should the scientist set the riders to on the triple beam balance? 53.0g because, 50.0g + 3.0g 7.5g because, 0.5g + 7.0g 67.0g because, 40.0g g Page 2

40. The difference between mass and weight is? 41. The procedure for finding the volume of an irregular shaped solid is; Mass is the amount of matter in an object and weight is a measure of the force of gravity between to objects. 1.Fill the graduated cylinder to 50.0 mL. 2.Slowly drop the object into the water, on a angle. 3.Figure out how much the water rose by subtracting. 4.The difference is the answer in cm 3
