Lesson 1 Tools of the Trade

• Lab Equipment and Safety
• You worked in groups to identify a tub full of
  lab equipment. You then sketched and labelled
  each tool

items and where in the room are they?

• Goggles
• Eye Wash
• Fire Extinguisher

Lesson 2 A Penny for Your Thoughts

• Introduction to Chemistry
• You practiced the art of alchemy, by turning a
  copper penny into gold!

7
Check in

• 1. 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 you were successful in turning your
  penny into gold? Explain your thinking.

Check in

• 2. What is chemistry?

9
Lesson 3 Whats the Matter?

• Defining Matter
• You read pages 7-12 in your text book and
  answered questions on a handout.

10
Check in

• 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.

11
Check-in

• 3.Which of the following can be classified as
  matter?

• a beam of sunlight b. an automobile
• c. an idea d. your breath
• e. rain f. sadness

12
Lesson 4 Mass Communication

• Mass and Volume
• You completed a density mini- lab, where you
  practiced measuring the mass and volume of
  different objects. You then answered summary
  questions about the lab.

13
Check in

• How do you determine the masses of objects?
• How do you determine the volumes of a square
  object?
• How do you determine the volume of an oddly
  shaped object?

14
Check in

• 4. Which has more mass and weighs more, 5
  kilograms of bricks or 5 kilograms of feathers?
  Explain your thinking.
• 5. Would it hurt more to be hit with 5 pounds of
  feathers or 5 pounds of bricks? Explain your
  thinking.

15
Lesson 5 All That Glitters

• Density
• You observed 3 density demonstrations (fish tank,
  magic candles, and the liquid stack) and
  completed a density mini- lab. You then answered
  summary questions about the lab.

16
Check in

• 1. In the year 250 B.C.E., King Hiero
  commissioned a goldsmith to make him a crown out
  of pure gold. However, when he received the
  crown, he suspected that the goldsmith had taken
  some of the gold and replaced it with a cheaper
  metal, even though it still weighed the same. He
  asked Archimedes to determine whether the crown
  was solid gold.
• How do you think Archimedes determined whether
  the crown was solid gold?

17
Check in

• 2. How can you use mass and volume to determine
  the identity of a substance?

18
Check-in

• 3.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
  volume of 1.1 mL.
• Is this coin truly gold? Explain. (The density of
  gold is 19.3 g/mL.)

19

• Common materials and their densities.

Material Density Material Density
zinc 7.1 g/cm3 gold 19.3 g/cm3
paper 0.9 g/cm3 brass 8.4 g/cm3
water 1.0 g/mL copper 9.0 g/cm3
aluminum 2.7 g/cm3 lead 11.4 g/cm3
