Integrated Physics and Chemistry Unit 3A

Big Idea:

How matter can be combined, reacted, and organized.

Student Expectations:

Priority TEKS

I.3A Analyze, evaluate, & critique sci. explanations by using empirical evidence, logical reasoning, & experimental & observational testing, including examining all sides of scientific evidence of those scientific explanations.

I.3D Evaluate the impact of research on scientific thought, society, & the environment.

I.3F Research & describe the history of physics & chemistry, & contributions of scientists

I.6D Relate the physical & chemical behavior of an element, including bonding & classification, to its placement on the periodic table.

Student Learning Targets:

I will explain the modern model of the atom.

• I know the parts of the atom.
• I know the location of each subatomic particle.
• I know how to use mass number and atomic number to find the number of neutrons in an atom.
• I can explain how isotopes are similar and different from each other.
• I can explain how the periodic table can be used to explain the properties of an element.

I will use the periodic table to predict the behavior of elements when they are alone or combined.

• I can predict whether elements are metals, nonmetals, or metalloids using the periodic table.
• I can distinguish between the different families of elements on the periodic table.
• I can summarize the properties of metals including oxidation # & electronegativity.
• I can illustrate the properties of nonmetals including oxidation # & electronegativity.
• I can use a spectrometer to distinguish the spectra of different elements.
• I can use a spectrometer to analyze white light.
• I can use a flame test to infer which elements were in a sample.
• I can explain how the size of atoms changes in a family & in a period in the periodic table.

I will explain how historical ideas about atoms led to our modern model of the atom.

• I can explain how our picture of the atom went through several changes as we learned more about atoms.
• I can explain why the modern model of the atom is an improvement over the previous models of the atom.
• I know the contributions of various scientists to the modern model of them atom. (Ex. Rutherford, Thomson, Bohr)
• I can explain the contributions of various scientists to the structure of the periodic table.
