16. Chemicals What are they??
There is nothing you can touch or hold that is not made of chemicals.
17. What is Chemistry? Chemistry is the science of the properties, composition, and behavior of materials.
Chemistry is the science concerned with describing and explaining the different forms of matter and the chemical reactions or matter.
18. Branches of Chemistry Applied Chemistry - the search for and isolation of useful materials.
Theoretical Chemistry - Provides a chemical view of nature and explanations of natural processes.
19. Chemistry is the Central Science
21. Scientific Thinking Make observation
Gather facts (more observations)
Propose hypothesis (tentative explanation)
Test hypothesis (perform experiment)
Gather more facts and generate new hypothesis
Re-test new hypothesis - Show that results are reproducible
Propose theory
22. From Scientific Model Hypothesis- a tentative explanation for an observation. (An unproven theory)
Experiments – tests that look for observable predictions of a hypothesis or theory
Laws – brief statements that summarizes past observations and predict future ones
Theories or Models - unifying explanation for a set of observations, facts, and laws
