Lesson 1:

Penny for Your Thoughts

  • Long ago, early scientists tried to turn ordinary things into gold. This pursuit was called alchemy and the people who engaged in alchemy were called alchemists.
    • Do you think the alchemists were successful in turning things to gold? Explain your thinking.

Lesson 2:

Whatsa Matter?

  • Modern chemistry is defined as the study of matter.
    • What do you think matter is?
    • Name two things that are matter and two things that are not matter.

Unit 1 • Investigation I

Notes

  • Here are some textbook definitions of matter:
    • Matter is anything that has mass and volume.
    • Matter is anything of substance in the known universe.
    • Matter is anything that takes up space.

(cont.)

Unit 1 • Investigation I

mass volume
Mass & Volume
  • Mass is the amount of matter in an object substance. We measure mass by measuring it on a scale or balance.
  • Volume refers to the amount of space occupied by a substance.

Unit 1 • Investigation I

properties of matter
Properties of Matter
  • The intrinsic property of a substance is a property that doesn’t depend on size and shape.
  • It is generally not easy to determine intinsic properties from the appearance of a substance.
  • Ex. Reactivity, flammability, density

Unit 1 • Investigation I

properties of matter1
Properties of Matter
  • Extrinsic Properties of matter are properties that can be observed qualitatively.
  • Ex. Color, size, shape, texture

Unit 1 • Investigation I

density
Density
  • Density is defined as the mass per unit volume or how much “stuff” there is in a certain space. Density is an intrinsic property of matter.

D = m  v

D= density (g/ml or g/cm3)

M= mass (g)

V= volume (ml or cm3)

  • Which of the following can be classified as matter according to our definition?
  • a) a beam of sunlight
  • b) an autmobile
  • c) an idea
  • d) your breath
  • e) rain
  • f) sadness

Unit 1 • Investigation I

wrap up
Wrap-Up
  • Matter is everything that takes up space.
  • Matter exists in many forms.

Lesson 4:

All That Glitters

  • In the year 1 B.C., King Hiero commissioned the creation of a golden crown. However, he didn’t believe that the goldsmith used all gold. He asked Archimedes to determine if the crown was solid gold.

(cont.)

Unit 1 • Investigation I

(cont.)

  • Do you think Archimedes can determine if the crown is solid gold by putting it under water? Why or why not?
  • What happens to the level of the water if you submerge a crown in the water?

Unit 1 • Investigation I

the big question
The Big Question
  • How can we use mass and volume to prove whether or not a substance is gold?

Unit 1 • Investigation I

you will be able to
You will be able to:
  • Find the mass, volume, and density of solid objects.

Unit 1 • Investigation I

activity
Activity
  • Purpose: It is not always easy to tell one form of matter from another. This activity will show you how to differentiate between different forms of matter by examining density, one of the physical properties of matter.
  • density = mass ÷ volume

  • In 1999 the United States Mint produced a coin called the Golden Dollar. It features an image of Sacagawea, the famous Native American guide for Lewis and Clark. It has a mass of 9.8 g and a volume of 1.1 mL.
    • What is the density of this coin?
    • The density of gold is 19.3 g/mL. Is this coin truly gold? Explain.

  • Density is an intrinsic physical property of matter. It is a measure of the mass per unit of volume of a substance.
  • One substance can be distinguished from another by examining its intrinsic physical properties.
