Explore the concept of evaporative cooling through a hands-on experiment. Use a wet cloth and fan to model an air-conditioner and use temperature and relative humidity sensors to collect data. Then digitally plot the data using graphs in the activity. In an optional extension, make your own modifications to improve the cooler's efficiency.
Many papers by Ken McClay and colleagues have established the value of scale-model experiments in understanding the evolution and geometries of extensional fault systems (e.g. T. Dooley and K.R. McClay, 1997, Analogue modeling of pull-apart basins: American Association of Petroleum Geologists Bulletin, v. 81, no.11, p. 1804 -- 1826).
There are few resources available that help students visualize the dynamic nature of faulting, especially the complex interplay of faults during growth and evolution of a fault system. Such an understanding is critical, however, if students are to think meaningfully about fault geometries and what they imply.
Conducting scale-model experiments in a class setting is useful, but very time-consuming, difficult for all students to see well, and very temporary, except for the end product. Accordingly, taking a cue from a movie produced by Ken McClay, I constructed a deformation apparatus, conducted and filmed several experiments conducted by McClay, and then produced QuickTime movies of the experiments. This approach makes it possible for students to observe an experiment in a minute or two that took 30-45 minutes to produce and to view the experiment repeatedly, so as to become very familiar with all that is taking place.
Individual frames from the movie provide a template on which students can identify the sequence of fault development, rotation of features, and cessation of motion on some faults as they become inactive. Requiring students to document their observations, establish a chronological sequence of events, and explain in writing what happens during the experiment results in an increased awareness of the faulting process.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Congenital heart defects affect approximately 1% of all babies born each year and account for almost 20% of all newborn deaths. Early diagnosis while still in the womb can greatly improve an affected baby’s chance of survival. Unfortunately, diagnosis relies exclusively on ultrasound imaging, where accurate readings aren’t guaranteed. Researchers in Japan are tackling this problem by enlisting the help of artificial intelligence. More importantly, they’re helping the doctors entrusted with patient care to understand how AI programs spot heart defects. Advancements in artificial intelligence have improved how congenital heart defects are diagnosed. Ultrasound videos of fetal hearts beating normally and others with structural defects can be studied with AI, which can then determine whether the fetal hearts in new videos are abnormal or not..."

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 introductory-level lab activity, students first view a 20-minute portion of an informative video to learn about the operation of an array of moored buoys that is used to detect changes in the El Ni��o Southern Oscillation (El Ni��o, "normal", and La Ni��a conditions)in the equatorial Pacific Ocean. Students then directly access, display, and work with recent and present data collected from the buoy system using the Tropical Atmosphere Ocean project website. Finally, students examine data from a coral geochemical record to infer past ENSO events.

This is a collection of mathematics problems relating to the moons of the solar system. Learners will use simple proportional relationships and work with fractions to study the relative sizes of the larger moons in our solar system, and explore how temperatures change from place to place using the Celsius and Kelvin scales.
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.

Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. In this video, Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.
