6 ) Develop models to illustrate the concept of half-life for radioactive decay.

a. Research and communicate information about types of naturally occurring radiation and their properties.

b. Develop arguments for and against nuclear power generation compared to other types of power generation.

During this activity, the students will collaborate in groups of 4 to complete a List-Group-Label as a before strategy for a lesson on radioactivity to activate and assess students' prior knowledge.  The students will collaborate on a shared Google document to create a brainstorm of all the words and concepts they know that are associated with the word, radioactive. Then, they will group the words into categories and ultimately label each group of terms. This activity will give the teacher insight into student's thoughts and possible misconceptions about radiation before a lesson on radioactivity. 

This activity was created as a result of the GAP Resource Summit.

6 ) Develop models to illustrate the concept of half-life for radioactive decay.

a. Research and communicate information about types of naturally occurring radiation and their properties.

b. Develop arguments for and against nuclear power generation compared to other types of power generation.

In this virtual lab, students simulate the radioactive half-life of four different elements. They record the data in a digital table, graph the data, and then answer journal questions based on their findings.
