Students explore radioactive decay.  In this radioactive atoms lesson students complete a lab to help them understand the relationship between radioactive atoms vs stable atoms. 

In this nuclear chemistry learning exercise, learners solve nine decay problems. They determine what forms in each problem given the radioactive element.

Students dramatize the oral disease process caused by bacteria which leads to tooth decay.

Students explore the concepts of rdioactive decay and dating. They generate a radioactive decay table, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in...

Third graders examine the reasons why it is important to take care of their teeth. As a class, they sing the toothbrush song and read about tooth decay. They identify the parts of the teeth and identify foods that can keep the mouth...

Students simulate the dating process with popcorn. In this geology lesson, students discuss how geologist find the age of rocks by gauging the amount of decay of radioactive elements. They have 6 bags of popcorn and each group microwaves...

Students explore decay functions and the half-life of a substance. Through an M&M activity with calculators, students collect and graph data. They determine the linear, quadratic and exponential functions of the graph. Students...

Students complete activities to study decomposition. In this decomposition lesson, students work in pairs to observe a decay buffet experiment. Students keep compost bag journals. Students define and discuss the process of decomposition.

Students define lake life zones. They define stormwater runoff and its effects on lakes. They identify the relationship between decaying substances and water pollution. They construct a freshwater food web.

In this music worksheet, students study the elements of a musical composition: silence, pitch, texture, dynamics, tempo, attack and decay and duration. Students complete 7 questions about these elements. Prior knowledge is assumed.

In this music activity, students learn 6 elements of music and match the names with the definitions. The elements are silence, pitch, texture, duration, dynamics, tempo and attack and decay.

In this elements of music learning exercise, students review the terms: silence, attack and decay, dynamics, pitch, duration, tempo, and texture as they fill in the blanks with the terms in 7 sentences. In addition, students complete 1...

In this music worksheet, 7th graders fill in the blanks in 7 sentences that describe the elements of music such as tempo, pitch, decay, and duration. They use the words from a word bank at the bottom of the page. They make a word search...

In this analogies worksheet, students complete the analogies about fuel, carbon dioxide, decay, and more. Students complete 10 analogies.

Students use properties of exponents to solve equations. In this algebra lesson, students add, subtract, multiply and divide exponential functions. They graph and differentiate between exponential growth and decay.
