2.1 Isotopes & Subatomic Particles
- Identify subatomic particles, their charges, relative masses, and locations in the atom
- Recognize changes to an atom with changes in a subatomic particle, including how those numbers relate to atomic number, mass number, and charge
- Define atomic mass and use isotopic abundance to calculate
2.1a Almost everything you need to know about isotopes (a PhET sim)
2.1b What is the atomic mass of beanium?
- What question were you trying to answer and why?
- What did you do during your investigation and why did you conduct your investigation in this way?
- What is your claim, evidence, and reasoning?
2.1c Atom Structure
(Link to YouTube)
Here is a summation of atomic structure and subatomic particles.
Below is the simulation for you to practice with in order to clarify anything that still seems fuzzy. Be sure to fill out the Flipped Questions when you finish and ask any questions you still have during class.
2.2 History of Atomic Theory
- Describe the history of the atomic model, including Dalton's Atomic Theory, the discovery of the electron, the Plum Pudding model, and Rutherford's gold foil experiment
- Explain how the model of the atom was empirically developed without ever actually "seeing" the atom
2.2a Historical Context
2.2b Atomic History Graphic Organizer
- Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology. Students create original works as a means of personal or group expression. Students use of models and simulations to explore complex systems and issues.
- Students apply digital tools to gather, evaluate, and use information. Students locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media.
- Students demonstrate a sound understanding of technology concepts, systems, and operations. Students troubleshoot systems and applications and transfer current knowledge to learning of new technologies.
- Students use critical thinking skills to plan and conduct research, manage projects, solve problems, and make informed decisions using appropriate digital tools and resources. Students collect and analyze data to identify solutions and/or make informed decisions. Students use multiple processes and diverse perspectives to explore alternative solutions.
- Students understand human, cultural, and societal issues related to technology and practice legal and ethical behavior. Students exhibit a positive attitude toward using technology that supports collaboration, learning, and productivity. Students demonstrate personal responsibility for lifelong learning.
