Summative Assessment Rubric: Radioactive Decay

SPS4. Obtain, evaluate, and communicate information to explain the changes in nuclear structure as a result of fission, fusion and radioactive decay a. Develop a model that illustrates how the nucleus changes as a result of fission and fusion b. Use mathematics and computational thinking to explain the process of half-life as it relates to radioactive decay c. Construct arguments based on evidence about the applications, benefits, and problems of nuclear energy as an alternative energy source

Criteria
	In Progress 8 pts	Proficient 16 pts	Exceeds 24 pts	Points (N/A)
Model Draw or create a visual representation of the problem	In Progress Illustration is not a correct visual representation of the fission or fusion process and its parts are not labeled or the illustrations processes are incorrectly labeled.	Proficient Illustration is a correct visual representation of the fission or fusion process and is correctly labeled. However, its parts are inaccurately labeled or not labeled.	Exceeds Illustration is an accurate representation of fission or fusion and is correctly labeled as well as its parts of the process is correctly labeled.	Points
Similar Write a problem that is similar to the given problem	In Progress Equation for fission or fusion using an unstable isotope and radioactive decay nucleus is incorrectly written and solved.	Proficient Equation for fission or fusion using an unstable isotope and a radioactive decay nucleus is correctly written; however, the equation is solved incorrectly.	Exceeds Equation for fission or fusion using an unstable isotope and radioactive decay nucleus is accurately written and solved correctly.	Points
Explain Explain how you know the given solution is correct.	In Progress Explanation of radioactive decay equation provides inaccurate details of how an unstable isotope undergoes the decay process of fission or fusion using the equation.	Proficient A basic explanation is written to support the fission or fusion equation's answer. The explanation includes the isotope, type of decay based on the equation but is missing the steps by which the process of fission or fusion results in the formation of a new element.	Exceeds A clear and detailed explanation of the solution supports the equation's answer. The explanation includes the isotope, type of decay, the process of how fission or fusion occurs, and the steps by which the process results in the formation of a new element.	Points
Retry Model the solution using a different method or technique	In Progress Half-life word problem is inaccurately written to interpret the fission or fusion decay process equation. The word problem does not include the equation's unstable isotope, or amount of sample. The mathematical work is not written and world problem is incorrectly solved.	Proficient Half-life word problem is written to represent the fission or fusion decay process equation. The word problem includes the equation's unstable isotope, amount of sample, and time. However, the mathematical work performed is not written or the solution is not correct.	Exceeds Half-life word problem is accurately written to represent the fission or fusion decay process equation. It includes the equation's unstable isotope, amount of sample and time. The mathematical work to solve the word problem is shown and its solution is correct.	Points
