Presentation Transcript

Slide 1: 

Objectives: Define volume. Measure the volume of an object. Tell the importance of reducing trash or waste. It's Science time!

Slide 2: 

Let’s have a review!

Slide 3: 

It's magic time!

Say something….. : 

Say something….. What do you think will happen to crumpled paper? Describe your observation Why do you think the paper didn’t get wet?

Slide 5: 

Air is also a matter thus it occupies space What is the term used to describe the space occupied by an object?

Measuring volume of Liquid : 

Measuring volume of Liquid Graduated Cylinder lower meniscus It is used to measure the volume of a liquid. Volume is the space occupied by the liquids. When a liquid is put into a cylinder, the surface curves. This curve is called meniscus.

When trying to measure the volume of an irregularly shaped object, the "water displacement method" is the most commonly used technique.. The procedure for the water displacement method is listed below.PROCEDURE:1) Find a graduated cylinder that will be large enough to fit the object(s) being measured.2) Fill this graduated cylinder enough so that when placed in the graduated cylinder, the object(s) in question will be fully submerged in the water. Also be careful not to put in so much water that the water level will rise past the graduated cylinder’s markings when the object(s) are placed in the graduated cylinder. 3) After filling the graduated cylinder to a satisfactory level, record the volume of the water as in your data. Make sure to read the meniscus when determining volume.4) After the water’s volume has been recorded, carefully place the object(s) in the graduated cylinder and record this volume as in your data. :

What is volume? : 

What is volume? What laboratory instrument can be used to measure the volume of an object?

Slide 11: 

VOLUME- is the amount of space occupied by an object can be measured using a ruler, graduated cylinder, or the formula L x W x H(thickness) Example: L= 10cm W= 5cm H= 2cm Answer:________cm3 When trying to measure the volume of an irregularly shaped object, the "water displacement method" is the most commonly used technique.

A box with crumpled paper! : 

A box with crumpled paper! How many more trash can fit inside the box? Do you think you can do something to lessen the volume of trash inside the box? How?
