What we Need These are liquids These are graduated cylinders ->

3
Need To Know When You pour a liquid into a graduated cylinder it looks like the liquid if bubbled like a contact lens. Contact lens

4
This is called the meniscus

5
When Measuring a liquid We have to get at eye level We take our measurement at the meniscus

6
Units and How To’s ml is the units = Milliliters We use the graduates and subgraduates to find our measure. In this case… Graduate : 50 Subgraduate : 5 So, our measure is: 55 ml

7
Your Turn to Try What is the Graduates? What are the Subgraduates? What is your measure if the units are ml.?

8
Your Turn to Try What is the Graduates? 20 What are the Subgraduates? About 1.5 What is your measure if the units are ml.? 21.5 ml

9
What happens when you add an object to the water?

10
The water gets displaced, but why? Objects have their own volume. When the object is added the water is displaced by the amount of volume of the object. We can find the volume of an object by taking the measure before and after the object is added and then subtracting the two measures.

11
You try to find the volume of the dino using displacement. Step 1: What is the volume of the liquid before the dino is in it? Step 2: What is the volume of the liquid after the dino is added? Step 3: Subtract the two measures this is the volume of the dino. What is it?

12
You try to find the volume of the dino using displacement. Step 1: What is the volume of the liquid before the dino is in it? 4.8ml Step 2: What is the volume of the liquid after the dino is added? 5.6ml Step 3: Subtract the two measures this is the volume of the dino. What is it?.8ml
