6. What is matter? Anything that has mass and occupies space!
L. Bernard, 2016

7. Are chemicals matter?
A chemical is any substance that takes part in a chemical reaction or is the product of a chemical reaction
Since they all have mass and volume, all chemicals are matter!
L. Bernard, 2016

8. Remember! Matter cannot be created nor destroyed!
The Law of Conservation of Mass
We can’t create something out of nothing
L. Bernard, 2016

12. Pure vs Applied Pure chemists research the fundamentals of chemistry
Pursuit knowledge of chemistry just because
L. Bernard, 2016

13. Pure vs Applied
Applied chemists research chemistry to answer a specific question
Pursuit knowledge of chemistry to solve a problem
L. Bernard, 2016

18. The Scientific Method
L. Bernard, 2016

19. The Scientific Method is…
A systematic approach to solving scientific problems
In other words, a list of steps that help us when we are experimenting in the lab
L. Bernard, 2016

20. The Scientific Method Use your observation to make a hypothesis
L. Bernard, 2016

21. The Scientific Method
Design an experiment to test that specific hypothesis
Independent Variable-the variable that is changed; manipulated variable
Dependent Variable- the variable that is observed; responding variable
L. Bernard, 2016

22. The Scientific Method After experimenting, evaluate your results
Was your hypothesis supported?
Do you need to perform more trials?
How can you revise your hypothesis?
What improvements could be made?
L. Bernard, 2016

23. The Penny Drop How many drops of water will fit on the top of a penny?
Use the scientific method graphic organizer to create your own experiment regarding this question:
How many drops of water will fit on the top of a penny?
What other criteria could affect how many drops of water fit on the penny?
L. Bernard, 2016

L. Bernard, 2016

30. Solving Numeric Problems
Analyze
What do you know?
What do you not know?
What can you do to find what you do not know?
Calculate
Conversions or equations
L. Bernard, 2016

31. Solving Numeric Problems
Evaluate
Does your answer make sense?
Did you use the correct equations?
Was the data copied correctly?
Where there any errors that you made?
Are your units correct?
L. Bernard, 2016

32. Solving Non-numeric Problems
Analyze, then solve!
No numbers mean no calculations
You still need to determine what you know and don’t know, then develop a plan
Apply concepts to the problem
