In the essay ‰"Mother Tongue,‰" Amy Tan explains that she ‰"began to write stories using all the Englishes I grew up with.‰" How these ‰"different Englishes‰" or even a language other than English contribute to identity is a crucial issue for adolescents.

In this lesson, students explore this issue by brainstorming the different languages they use in speaking and writing, and when and where these languages are appropriate. They write in their journals about a time when someone made an assumption about them based on their use of language, and share their writing with the class. Students then read and discuss Amy Tan's essay ‰"Mother Tongue.‰" Finally, they write a literacy narrative describing two different languages they use and when and where they use these languages.

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.

This is a lesson about measuring magnetic field directions of Earth and in the environment. First, learners go outside, far away from buildings, power lines, or anything electrical or metal, and use compasses to identify magnetic North. Next, they use the compasses to probe whether there are any sources of magnetic fields in the local environment, including around electronic equipment such as a CD player and speakers. This is the first lesson in the second session of the Exploring Magnetism teacher guide.

Explore this Story Map to learn about Canada's Forests, Freshwater, Oil & Gas, Mineral and Mining natural resources. As you go through the story map, stop to consider the questions posed throughout.

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. By examining scientific visualizations of a data pair in two time slices, they will see that the environment is the result of the interplay among many processes that take place on varying time and spatial scales. This is one of six interrelated learning activities associated with the GLOBE Earth System Poster, Exploring Connections in Year 2007, which also includes a series of assessment and extension activities. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.

In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps. They observe that the environment is the result of the interplay among many processes that take place on varying time and spatial scales, by looking at different six different variables during a single month: insolation, surface temperature, cloud fraction, aerosols, precipitation and biosphere (surface vegetation). This is one of six interrelated learning activities in the student activity guide associated with the GLOBE Earth System Poster, Exploring Connections in Year 2007. A series of assessment and extension activities are included. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program.

In this activity, student teams explore the connections between parts of the Earth system by examining a time series of environmental data maps. Each student teams examines images for two variables and determines if there is a direct or inversely proportional relationship exhibited between them throughout the year. The variable pairs that student groups are observing include: insolation and surface temperature; cloud fraction and precipitation; aerosols and biosphere. This is one of six interrelated learning activities associated with the GLOBE Earth System Poster, "Exploring Connections in Year 2007," and includes a series of assessment and extension activities.

In this activity, student teams explore connections between parts of the Earth system, by examining a time series of environmental data maps. Each team examines a single variable displayed on a global data map, and identify the unit of measure, the range of values, and patterns they observe in the data. Variables include: insolation, surface temperature, precipitation, cloud fraction, aerosols, biopshere.

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

Students will explore time series plots and raw data to understand the role of sea surface temperature increases on arctic ice melt. This is part three of a four-part activity on polar science. The activity builds on the knowledge gained in Using Data and Images to Understand Albedo (part 2). Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. Information is provided on data access using the NOAA Earth System Research Laboratory Web site. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.

Writing gets personal when students interview family members in order to write a personal narrative about that person.

In this lesson, learners will construct their own 3-D glasses in order to use them on 3-D images, such as images of the Sun from the STEREO spacecraft. This activity requires special materials, such as red and blue acetate paper and can be used with an accompanying activity, titled Create Your Own 3-D Images.

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.
