1. Volume

2. What is volume: _______________________________________ _____________________________________ _____________________________________ _____________________________________ Units of Volume Millilitre (_______) Litre (____) Cubic centimetres (_____) Cubic millimitre (_____) Cubic meter (______) 1 mL = 1 cm 3

3. Taking a reading on a graduated cylinder To know the value of each graduation: - Find two major ______________________. - __________________them from eachother. - Divide by the number of _____________. Example: -Two major graduations 25 and 30 -So 30 – 25 = 5 -There are 5 spaces so: 5 / 5 = 1 - Each graduation is worth 1.

4. A) Volume of a liquid The instruments are: -________________________________________ ________________________________________ The meniscus: When the liquid is not perfectly flat, it will curve a little. You have to read under the meniscus. Meniscus

5. ________________ To measure 10 mL, you must pour 10 mL of water in the graduated cylinder and read under the menuscus.

6. _____________ ____________ You can try!

7. B) Regular solid (like erasers, boxes, etc.) Use a ______________ to measure the sides. For a rectangular prism or cube, use the following formula: V= ____________________________ V= Cylinder: V=πXr 2 Xh. π = 3.14 r = radius h = height

8. Example : ____________________________ You can try! 2 cm 3 cm 5 cm

9. C) Irregular solid Example: a nail, a penny, an eraser, a paperclip etc. You will need a ________________________ or an overflow can.

10. Water displacement method Fill the graduated cylinder with ____________________and write down the volume. (example 20 mL) ______________________________into the cylinder and read the new _________________. ________________________ the first reading from the second reading. The _______________________is the object’s volume. You can try ! Volume =___________________________

11. Overflow can -Place a beaker under the overflow can - Fill up the overflow can until the water is overflowing. -Place the object in the can. - Collect the water that overflows and measure its volume.

12. Volume lab activity Object Volume measured with a ruler Volume measured by water displacement Small metal cylinder Large metal cylinder Rectangular prism Marble Rubber stopper
