Students conduct an experiment to study the acceleration of a mobile Android device. During the experiment, they run an application created with MIT's App Inventor that monitors linear acceleration in one-dimension. Students use an acceleration vs. time equation to construct an approximate velocity vs. time graph. Students will understand the relationship between the object's mass and acceleration and how that relates to the force applied to the object, which is Newton's second law of motion.

In this activity, students will explore two given websites to gather information on Bone Mineral Density and how it is measured. They will also learn about X-rays in general, how they work and their different uses, along with other imaging modalities. They will answer guiding questions as they explore the websites and take a short quiz after to test the knowledge they gained while reading the articles.

Students observe multiple examples of capillary action. First they observe the shape of a glass-water meniscus and explain its shape in terms of the adhesive attraction of the water to the glass. Then they study capillary tubes and observe water climbing due to capillary action in the glass tubes. Finally, students experience a real-world application of capillary action by designing and using "capillary siphons" to filter water.

Students explore the sound, evolution, performance techniques, and culture of guitar-like instruments from around the world.

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of preselected objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system.

Students create movements to represent long and short rhythmic patterns and compose patterns using non-traditional notation.

Diverse literary texts provide opportunities for making connections about race and hearing multiple voices and perspectives. In this activity, students read literature and poetry from different American writers, reflecting on the meaning and experiences of race in the United States. Due to copyright restrictions, we cannot reproduce the texts here, but the instructions below include anthologies and links to online sources where the texts can be printed out.

In this lesson students look at primary source images and read short secondary texts to understand slave life. In the activity, the teacher models and students practice differentiating between different types of text (primary, secondary, etc.) they might encounter in the social studies classroom. Students show their understanding of a passage's central concepts by selecting words and phrases to compose a "found poem" about the main ideas of the text. This lesson was designed for struggling readers and ESL/ELL students.

Students will review their knowledge of tension and focus on tensile loads and failure caused by them.

To evaluate the different integumentary systems found in the animal kingdom, students conduct an exploratory research-based lab. During the activity, students create a model epidermis that contains phosphorescent powder and compare the results to a control model. After learning about the variations of integumentary systems—systems that comprise the skin and other appendages that act to protect animal bodies from damage—students act as engineers to mimic animal skin samples. Their goal is to create a skin sample that closely represents the animal they are mimicking while protecting the base ‘epidermis’ from UV light.

In this lesson students read poems and letters that describe the work and lives of nineteenth-century Irish immigrants to the United States. As students read the documents, they choose words and phrases to create found poems that reflect their understandings of the Irish-American experience.

Students test and observe the "self-cleaning" lotus effect using a lotus leaf and cloth treated with a synthetic lotus-like superhydrophobic coating. They also observe the Wenzel and Cassie Baxter wetting states by creating and manipulating condensation droplets on the leaf surface. They consider the real-life engineering applications for these amazing water-repellent and self-cleaning properties.

Students will observe/investigate the movement of water through the different stages of the water cycle and determine what drives this cycle. Students are asked to think about what precipitation is then watch a video about why the water cycle is important. They observe a simple version of the water cycle and take some notes. Students are asked what stages require solar radiation, which require water to give off heat, and which are driven by the force of gravity. The teacher does several different demonstrations while students fill in a sheet that has the students recording their observations of different processes in the water cycle and how energy is involved. Students build their understanding of the water cycle through the different models that are shown or experienced. The culminating activity has them create their own model of the water cycle from the viewpoint of a water molecule including the processes, the energy involved, and gravity.

In this task students prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals.

This problem illustrates how an exponentially increasing quantity eventually surpasses a linearly increasing quantity.
