Which country is credited for developing the metric

system.

3

France

4

Which of the following are reasons why the metric system is used by every

nation, except the U.S.? Answer YES or NO for each. “YES” means it is a good reason and “NO” means this is not a good reason or not the right reason.

a) The Metric System is based on factors of 10; this means that when making metric conversions you just need to move the decimal point.

b) The metric system is based off parts of the body, so it is fun to use.

c) The metric system eliminates confusion when everyone uses it.

d) A millimeter is very small, so it allows very precise measurements to be taken.

5

A, C, and D are all reasons why the metric system is used, rather

than the former English system, by other

countries.

6

What is the metric base unit for:

a)Mass = ___________

b) Volume = __________

c) Length = __________

7

a)Gramb)Literc)Meter

8

The __________ System is based on measurements of the Earth, while the ___________ System is based on

random objects; usually parts of the human body.

9

The __METRIC__ System is based on measurements of the Earth, while the __ENGLISH__ System is based

on random objects; usually parts of the human body.

10

a) T or F : The Metric System allows more precise measurements because the increments are smaller.

b) T or F : The Metric System helped eliminate confusion and controversy that existed with the English System.

c) T or F : The English System was well planned and thought through in its creation.

d) T or F : Most countries currently use the English System of Measurement, while only science uses the Metric System.

11

a)Trueb)Truec)False: the creation of the English

system was pretty random and not well planned.

d)False: Pretty much every country uses the metric system except for the US AND science also uses the metric system.

What is the volume of the dinosaur?

QuickTime™ and a decompressor

are needed to see this picture.

19

The volume of water before the dinosaur is in the water

Is 4.8 mL.

The volume of water after the dinosaur is in the water

Is 5.6 mL.

To get the volume of the dinosaur: 5.6 mL - 4.8 mL

= 0.8 mL

This method of volume measurement is called water

displacement.

A) What is the density of the object below?Show your work…don’t forget your units.

2 cm

Mass = 32 grams

B) Will this object sink or float in water?

21

A) The volume = 4cm x 2cm x 2cm = 16cm3Density = Mass / VolumeSO…32grams / 16cm3 =

2 grams/cm3

B) The density of water = 1.0 g/mLThis object’s density is greater than 1.0, so the

object will sink.

48

In this experiment which measures the temperature of a chemical

reaction over time, the temperature decreases as time went on. Which

of the below graphs would show this?

49

Correct Answer = BSince the temperature

goes down as time goes on, the relationship is

indirect.

area piece of foil had the fastest reaction rate?

b) How could you tell by the slope of the line

on the graph which surface area had the fastest

reaction rate?

51

a)The large surface area piece of foil had the fastest reaction rate because it had more foil in contact with the chemical.

b)The line with the steepest slope was the foil piece with the fastest reaction rate.
