The repeating patterns of this table reflect patterns of outer electron states.ĭevelop, revise, and/or use a model based on evidence to illustrate and/or predict the relationships between systems or between components of a system.ĭevelop and/or use a model (including mathematical and computational) to generate data to support explanations, predict phenomena, analyze systems, and/or solve problems. The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.The following DCI, SEPs, and CCCs are addressed at some point within The Periodic Table, Elements, and Their Bonds:ĭCI: PS1.A: Structure and Properties of Matter That is, the task of answering the question requires that the student utilize at least two of the three dimensions of the NGSS science standards - a DCI, a CCC, and/or an SEP. Each question is either a 2D or (preferrably) a 3D question. There are 44 multi-part questions organized into 13 Question Groups and spread across the four activities. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.Īs a whole, the questions in this task address a wide collection of disciplinary core idea (DCI), crosscutting concepts (CCC), and science and engineering practices (SEP). Collectively, the four parts were designed to address the following NGSS performance expectation: ![]() Each part involves a different type of skill or understanding. ![]() This NGSS-inspired task consists of four parts. The activity addresses the HS-PS1-1 Performance Expectation of the Next Generation Science Standards. The Periodic Table, Elements, and Their Bonds focuses on the relationship between the location of an element on the Periodic Table and its tendency to form an ionic, covalent, or metallic bond with other elements on the table. As is the case for most topics in Chemistry, we recommend that students have ready access to a Periodic Table as they proceed through this activity. ![]() For this particular Science Reasoning Center activity, the information that is required to answer the question is either given in the specific question or involves use of The Periodic Table. This information is accessible by tapping on the small thumbnails found on the bottom right of every question. Like all our Science Reasoning Center activities, the completion of The Periodic Table, Elements, and Their Bonds activity requires that a student use provided information about a phenomenon, experiment, or data presentation to answer questions.
