Standard #: SC.8.P.8.7 This document was generated on CPALMS - www.cpalms.org 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). Subject Area: Science Grade: 8 Body of Knowledge: Physical Science Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia. B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object. Weight, on the other hand, is the measure of force of attraction (gravitational force) between an object and Earth. The concepts of mass and weight are complicated and potentially confusing to elementary students. Hence, the more familiar term of "weight" is recommended for use to stand for both mass and weight in grades K-5. By grades 6-8, students are expected to understand the distinction between mass and weight, and use them appropriately. Clarification for grades K-2: The use of the more familiar term ‘weight’ instead of the term “mass” is recommended for grades K-2. Clarification for grades 3-5: In grade 3, introduce the term mass as compared to the term weight. In grade 4, investigate the concept of weight versus mass of objects. In grade 5, discuss why mass (not weight) is used to compare properties of solids, liquids and gases.

Lesson Plan Name Description This is lesson 1 of 3 in the Atomic Structure unit. This lesson helps Atomic Structure Unit: Lesson students determine charge, structure and location of different 1 - Science of an Atom components of an atom. This lesson also allows students to sketch the first 18 elements from the periodic table. This is lesson 2 of 3 in Atomic Structure unit. This lesson helps Atomic Structure Unit: Lesson students sketch atoms by placing electrons, neutrons and protons by 2 - Build Atom in Scratch referring to the periodic table. This lesson also helps students upload/draw costumes on Scratch to create animated objects. This is the final lesson 3 in the Atom Structure unit. This lesson allows students to program in Scratch and switch the costumes Atomic Structure Unit: Lesson based on the operational conditions placed on the sprite. The final 3 - What's my element? product in this lesson will showcase the student’s conceptual understanding of the atomic structure in a computer science medium. Students take visitors on a trip through time to view the development of the atomic theory. During the presentation they list Atomic Theory Exhibit scientists who contributed to our understanding, give dates, and display diagrams that represent the atom in various stages of its development. This lesson provides students with the basic foundations of atomic theory and a simple understanding of the periodic table. It provides an easy-to-understand Prezi presentation before leading students Build An Atom into an easy and fun atom building simulation. Assessments are scored by the progam. A vocabulary website is also provided. It can be used on iPads or in a computer lab. Students will be able to explain what an atom is and what its subatomic particles are. Students will be able to read and locate the number of protons for each element on the periodic table. Knowing Exploring the Atom! the location of the protons, they will gain knowledge about the electrons and the neutrons. They will also be able to model an atom and properly locate the protons, neutrons, and electrons. Students learn the charge and location of subatomic particles by Interactive classroom atom dressing as them and creating an atom model in the classroom. Through this engaging activity students work as a group to create models of isotopes with stickers and construction paper. Students Mystery Isotopes also use models created by their peers to analyze the number of subatomic particles and determine isotopes' names. All worksheets and data collection sheets are included. In this Model Eliciting Activity (MEA), students will use their knowledge of the organization of the periodic table and the basic Periodic Table - Atoms and properties of atoms to determine which elements should be used to Bonding develop compounds with two atoms of different elements. Students must determine the number of protons, neutrons, and electrons in a neutrally charged atom of an element using the periodic table. They must also determine which elements will likely bond together using their location on the periodic table. Students completing this MEA will develop two short essay responses to a client in the scientific industry. This lesson will teach the concept of differences between stable Stable Atom, Ion, or Isotope? atoms, ions, and isotopes. The students will take their knowledge of the atomic theory and will build models of varying atomic forms. Text Resource Name Atomic Theory We Are Stardust Description This article is intended to support reading in the content area. The article provides a chronological description of the development of the atomic theory. Beginning with debates by Greek philosophers in the sixth century B.C., the various beliefs about atoms are explained. For around 2000 years, the subject lay dormant, until John Dalton developed his atomic theory in the 1800s. Delving into tests of Dalton's theory, the author explains how scientists, over time, developed what we now know as the modern day atomic theory. This informational text resource is intended to support reading in the content area. This text examines how humans and all things around us are made of elements created in stars. The article references fusion, the powerful collision of enormous stars, and the intense explosion of supernovas. All of this is tied to the creation of heavier elements that hurtle through space, to be reassembled as distant solar systems. Virtual Manipulative Name Description Build an atom out of protons, neutrons, and electrons, and see how Build an Atom the element, charge, and mass change. Then play a game to test your ideas! This Flash interactive activity explores atomic structure at a pace that middle school students can easily understand. It contains 26 animated pages that depict the atomic nucleus and the three primary Teachers' Domain: The Atom subatomic particles: electrons, protons, and neutrons.
