This Question Exploration and Concept Comparison asks the Essential Question: What are the parts of the atom, and how was the modern atomic model developed?
As practice or after-class assessment review, I would recommend using my logic line-up activity on parts of the atom
. If you wanted to do a deeper dive, after quarks, explain electron clouds
Question Exploration Routine and Concept Comparisons are instructional methods that teachers can use to help a diverse student population understand a body of content information by carefully answering a critical question to arrive at a main idea answer. Students taught using the content enhancement routines earned higher total test scores than did students taught using the lecture-discussion method.
Personally, I use the routines to figure out what I want to say and how I want to say it. I keeps my "Sage on the Stage" time limited to what fits onto 2-3 pages for the Question Exploration, and 1 page for the Frame. This product includes the completed routines, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in.
These Concept Enhancement Routines have the following learning objectives and outcomes:
- SWBAT identify the major contributors to modern atomic theory and their major contributions: Dalton, Thomson, Millikan, Rutherford, Chadwick
- SWBAT compare and contrast the “plum pudding” and nuclear (or Rutherford) atomic models.
- SWBAT describe Rutherford’s gold foil experiment
- SWBAT define atom and distinguish between protons, neutrons, and electrons;
- SWBAT describe the general structure of an atom including location and charges of the subatomic particles
- SWBAT Identify the properties of the nucleus of an atom;
- SWBAT Explain why some nuclei are unstable.
It covers the following Florida Next Generation Sunshine State Standard Benchmarks: SWBAT
SC.8.P.8.1: Explore the scientific theory of atoms (also known as atomic theory) by using models to explain the motion of particles in solids, liquids, and gases.
SC.8.P.8.7: Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons).
SC.912.P.8.3 Explore the scientific theory of atoms (also known as atomic theory) by describing changes in the atomic model over time and why those changes were necessitated by experimental evidence.
SC.912.P.8.4 Explore the scientific theory of atoms (also known as atomic theory) by describing the structure of atoms in terms of protons, neutrons and electrons, and differentiate among these particles in terms of their mass, electrical charges and locations within the atom.
SC.912.P.10.10 Compare the magnitude and range of the four fundamental forces (gravitational, electromagnetic, weak nuclear, strong nuclear).
SC.912.P.10.11 Explain and compare nuclear reactions (radioactive decay, fission and fusion), the energy changes associated with them and their associated safety issues.
SC.912.P.10.12 Differentiate between chemical and nuclear reactions.
