Over several days, students learn about composites, including carbon-fiber-reinforced polymers, and their applications in modern life. This prepares students to be able to put data from an associated statistical analysis activity into context as they conduct meticulous statistical analyses to evaluate/determine the effectiveness of carbon fiber patches to repair steel. This lesson and its associated activity are suitable for use during the last six weeks of an AP Statistics course; see the topics and timing note for details. A PowerPoint® presentation and post-quiz are provided.

Students will learn about bone structure, bone development and growth, and bone functions. Later, students will apply this understanding to answer the Challenge Question presented in the "Fix the Hip" lesson and use the acquired learning to construct an informative brochure about osteoporosis and biomedical engineering contributions to this field.

This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI. Exploring the properties of this solenoid helps students understand the MRI machine.

Students apply pre-requisite statistics knowledge and concepts learned in an associated lesson to a real-world state-of-the-art research problem that asks them to quantitatively analyze the effectiveness of different cracked steel repair methods. As if they are civil engineers, students statistically analyze and compare 12 sets of experimental data from seven research centers around the world using measurements of central tendency, five-number summaries, box-and-whisker plots and bar graphs. The data consists of the results from carbon-fiber-reinforced polymer patched and unpatched cracked steel specimens tested under the same stress conditions. Based on their findings, students determine the most effective cracked steel repair method, create a report, and present their results, conclusions and recommended methods to the class as if they were presenting to the mayor and city council. This activity and its associated lesson are suitable for use during the last six weeks of the AP Statistics course; see the topics and timing note for details.

This is a hands on activity where students will see how instruments can be used to warn people of a tsunami. This activity demonstration can be flexible to the needs and ages of the students and can be a game or a conversation.

Students use the spectrograph from the "Building a Fancy Spectrograph" activity to gather data about different light sources. Using the data, they make comparisons between the light sources and make conjectures about the composition of these sources.

In this activity, students take the age old concept of etch-a-sketch a step further. Using iron filings, students begin visualizing magnetic field lines. To do so, students use a compass to read the direction of the magnet's magnetic field. Then, students observe the behavior of iron filings near that magnet as they rotate the filings about the magnet. Finally, students study the behavior of iron filings suspended in mineral oil which displays the magnetic field in three dimensions.

Students will use this activity to determine what keeps our bones strong. Soaking the bones in vinegar will remove the calcium from the bones causing them to become soft and rubbery. Students will find that when we age, calcium is depleted from our bones faster than we can restore it. They will then determine what complications can arise from it.
