Students learn that buoyancy is responsible for making boats, hot air balloons and weather balloons float. They calculate whether or not a boat or balloon will float, and calculate the volume needed to make a balloon or boat of a certain mass float. Conduct the first day of the associated activity before conducting this lesson.

Students explore material properties in hands-on and visually evident ways via the Archimedes' principle. First, they design and conduct an experiment to calculate densities of various materials and present their findings to the class. Using this information, they identify an unknown material based on its density. Then, groups explore buoyant forces. They measure displacement needed for various materials to float on water and construct the equation for buoyancy. Using this equation, they calculate the numerical solution for a boat hull using given design parameters.

Using the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite. Students then interpret that map and compare and evaluate different color scales. Note that this is the Spanish version of Exploring Color Maps: Using Stratospheric Ozone Data.

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.

Student teams explore atmospheric aerosols, dust, and fires and their impact on the Earth's albedo using NASA Earth Observations (NEO) website. This is an extension activity in the student learning activity guide accompanying the GLOBE Earth System Poster, Exploring Connections in Year 2007. A series of six learning activities and associated assessment activities are included.
In this activity, student teams explore connections between parts of the Earth …
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. 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 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. 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.

Students conduct experiments to determine the flow rate of faucets by timing how long it takes to fill gallon jugs. They do this for three different faucet flow levels (quarter blast, half blast, full blast), averaging three trials for each level. They convert their results from gallons per second (gps) to cubic feet per second (cfs).

All of us have felt sick at some point in our lives. Many times, we find ourselves asking, "What is the quickest way that I can start to feel better?" During this two-lesson unit, students study that question and determine which form of medicine delivery (pill, liquid, injection/shot) offers the fastest relief. This challenge question serves as a real-world context for learning all about flow rates. Students study how long various prescription methods take to introduce chemicals into our blood streams, as well as use flow rate to determine how increasing a person's heart rate can theoretically make medicines work more quickly. Students are introduced to engineering devices that simulate what occurs during the distribution of antibiotic cells in the body.

Working individually or in groups, students explore the concept of stress (compression) through physical experience and math. They discover why it hurts more to poke themselves with mechanical pencil lead than with an eraser. Then they prove why this is so by using the basic equation for stress and applying the concepts to real engineering problems.
