Standard 1.1 What does it look like to demonstrate profciency on this standard? Obtaining information Students obtain information from published, grade-level appropriate material from at least two sources (literature, media, visual displays, data) about: ● The experimental design and resulting data of various experiments regarding the structure of the atom ● Conclusions drawn regarding the subatomic structure of the atom Evaluating information Students synthesize information that is presented in various modes (graphs, diagrams, photographs, text, mathematical, verbal) to describe: ● The development of various atomic models based on experimental evidence ● The strengths and limitations of the selection of a model used to describe a system at the atomic level Communication style and format Students use at least two different formats (oral, graphical, textual and mathematical) to communicate information based on experimental evidence regarding the structure of the atom including: ● The relative size and mass of the nucleus of an atom compared to the atom as a whole ● The relative size, mass, and charges of subatomic particles including protons, neutrons, and electrons ● Strengths and limitations of various models of the atom Connecting the DCIs and the CCCs Students identify and communicate evidence for the structure of the atom including: ● Each element has a unique atomic number (number of protons) in its nucleus ● Atoms of the same element may have different masses depending on the number of neutrons in the nucleus

Standard 1.2 What does it look like to demonstrate profciency on this standard? Organizing Data Students organize data that represents: ● The composition of nuclei before and after a nuclear process ● The properties and composition of the radiation released in a nuclear process Identifying Relationships Students analyze data to identify patterns including:
