Earth science ideas click fastest with real practice. This set gives your Grade 9-12 class ninety questions on radioactive decay as time.
Students will answer questions such as "Which isotope is commonly used in dating ancient organic materials?", "Which of the following best describes how scientists use decay rates?", and "Why is radiocarbon dating limited to relatively recent materials?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a standards aligned earth science unit. The unit also covers How Fossils Form, Fossil Preservation Types, Stratigraphic Principles, Cross Cutting and Index, Relative and Absolute Dating, and Combining Dating Methods, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 earth science classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard ES.9b.
