Integrated Physics and Chemistry TEKS Correlations
(8) Science concepts. The student knows that changes in matter affect everyday
life. The student is expected to:
(A)distinguish between physical and chemical changes in matter such as oxidation, digestion, changes in states, and stages in the rock cycle;

Students across the state seem to have a difficult time with IPC TEKS (8)(A). Students need to
explore the concept of physical and chemical changes in a number of ways. The first question
(63) integrates IPC with earth science. Students are introduced to the rock cycle in grade 6 and
continue to develop an in-depth understanding of it throughout middle school. The inclusion
of artwork means that the students do not have to memorize the rock cycle, but they should
be able to read the diagram and think about what causes a chemical change. It is important to
integrate the student’s science concepts from middle school into the high school sciences.
The second question (64) is something students may see in a classroom activity, and the last
question (65) is an application to the real world.
