Cluster - Presentation of Knowledge and Ideas
[SLCA.6-8.5] - Integrate multimedia components and visual displays into presentations to clarify information, strengthen claims and evidence and to add interest.
- Claim
Statement taking a position on what is true, usually one with which reasonable people might disagree. See Argument in Text Types and Purposes, Evidence, Thesis. - Evidence
Empirical data or other sources of support (e.g., mathematical proofs) for a claim; may be selected, presented, and evaluated differently by different audiences and in different subject areas according to the norms of disciplinary literacy. See Text Types and Purposes for Argument.
[8.PS.1.1] -
Develop a model to describe that (a) atoms combine in a multitude of ways to produce pure substances which make up all of the living and nonliving things that we encounter, (b) atoms form molecules and compounds that range in size from two to thousands of atoms, and (c) mixtures are composed of different proportions of pure substances. Clarification Statement: Examples of molecular-level models could include drawings, three-dimensional ball and stick structures, and computer representations showing different molecules with different types of atoms.
State Assessment Boundary: Valence electrons and bonding energy, the ionic nature of subunits of complex structures, complete depictions of all individual atoms in a complex molecule or extended structure, or calculations of proportions in mixtures are not expected in state assessment.
[8.PS.1.4] -
Develop a model that describes and predicts changes in particle motion, relative spatial arrangement, temperature, and state of a pure substance when thermal energy is added or removed. Clarification Statements: Emphasis is on qualitative molecular-level models of solids, liquids, and gases to show that adding or removing thermal energy increases or decreases kinetic energy of the particles until a change of state occurs. Examples of models could include drawings and diagrams. Examples of pure substances could include water, carbon dioxide, and helium.
