S.8.PS.4 analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. S.8.PS.5 develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. S.8.PS.6 undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.* Grade 8 Science Standard Earth and Space Science Content Topic Human Impacts Objectives Students will S.8.ESS.1 construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact systems. Earth’s Grade 6-8 Science Standard Engineering, Technology, and Applications of Science Topic Engineering Design Objectives Students will S.6-8.ETS.1 define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions. S. 6-8.ETS.2 evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. S. 6-8.ETS.3 analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success. S. 6-8.ETS.4 develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved. Grade 6-8 Science Standard Science Literacy Topic Reading- Key Ideas and Details Objectives Students will S.6-8.L.1 cite specific textual evidence to support analysis of science and technical texts. S.6-8.L.2 determine the central ideas or conclusions of a text; provide an accurate summary of the text distinct from prior knowledge or opinions.
