How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations of surfaces in the solar system. Materials required for the outdoor demonstration include a cement step, sand, laboratory thermometers, foam rubber, and a meter stick. An optional indoor experimental set up uses twin desk lamps with equal-wattage tungsten bulbs and an infrared thermometer. A student datasheet accompanies the activity.

In ScholCom 202X, you'll take on the role of a new scholarly communication librarian at a small public university somewhere in the US in the "distant future" of the year 202X.

You'll be given a number of scenarios derived from activities and questions a real scholarly communication librarian might expect to receive. These scenarios fall into four general areas: copyright; publishing; institutional repositories; and open access.

The game has two versions, an interactive fiction format written in Ink (located in the "Ink source" and "playable" folders) and a static PDF version (in "printables").

In the interactive fiction version, after reading each scenario you'll be given a chance to consult your "augment," a smartphone-like device which contains a very brief annotated list of some relevant sources and a calendar that tracks how busy you are. In the PDF/print version, these sources are listed below the scenario text, and are open access whenever possible.

After you've read the scenario text and consulted these sources (or not), put yourself in the place of the librarian in the game and think about how you would respond. Would you try to help just the person you're currently talking to, or would you rather build resources and develop strategies that could make the question easier to answer the next time it comes up, and potentially even reach and educate people who don't know the questions to ask in the first place?

As you think through each scenario, ask yourself how you would balance the desire to do a good job against the threat of overwork. You're welcome to write out what you would do, or just think about it. The PDF versions of the scenarios can also be used to role play in a classroom setting, with one student taking on the role of the librarian and another the role of the person who needs their help.

A computer simulator that allows students to adjust the air temperature and dew point to see what type of precipitation would fall to the ground.

This interactive tool allows viewers to explore, by county, the areas of California threatened by a rise in sea level through this century.

This web mapping tool allows users to investigate impacts of sea level rise. Data is included from across the United States at different scales. Various timelines and sea level rise projections can be explored.

This is an interactive map that illustrates the scale of potential flooding in Alabama, Mississippi, and Florida due to projected sea level rise. It is a collaborative project of NOAA Sea Grant Consortium and the US Geological Survey. It is a pilot project, so there is some possibility that the resource may not be maintained over time.

While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend the Earth's position in space, the Earth's rotation axis and seasons.

An interactive that illustrates the relationships between the axial tilt of the Earth, latitude, and temperature. Several data sets (including temperature, Sun-Earth distance, daylight hours) can be generated.

An interactive simulation of Earth's seasonal dynamics that includes the axial tilt and other aspects of Earth's annual cycle. This is part of a larger lab from the University of Nebraska at Lincoln: http://astro.unl.edu/naap/motion1/motion1.html

Secretos de los Hibernadores. El Centro de Extensión y Educación en Ciencias Naturales colabora con la facultad de CSU, los Parques Nacionales y los programas de ciencia ciudadana para traducir su investigación científica actual en experiencias STEM únicas para los estudiantes en forma de kits educativos que se pueden prestar. Cada kit contiene casi todos los materiales necesarios (menos cosas comunes como agua y toallas de papel) para explorar algunos temas de investigación científica realmente interesantes. enviando un formulario de recogida local o un formulario de entrega disponible en el sitio web vinculado. Utilice la información de contacto en la página de descripción general del kit STEM para obtener más información. https://www.cns-eoc.colostate.edu/stem-kits/ Este kit se proporciona de forma gratuita para uso educativo.

Secrets of the Hibernators STEM Kit. The Natural Sciences Education & Outreach Center collaborates with CSU faculty, National Parks and citizen science programs to translate their current scientific research into unique STEM experiences for students in the form of Educational Kits that can be checked out. Each kit contains just about all of the materials needed (minus common things like water and paper towels) to explore some really interesting scientific research topics.The kits are available for teachers and informal educators in Colorado to check out for a duration of a week by submitting either a local pickup form or a delivery form available at the linked website. This kit is provided free for educational use. This Kit is available in Spanish.

In this demonstration, students detect the interference of waves and measure wave phenomena using an experimental apparatus consisting of a laser pointer, a second surface mirror scrap (like a bathroom mirror) binder clips, razor blade, ruler, and a white wall or projection screen. Appendices with a discussion of physical principles and extension activities are included.

Explore different types of attractions between molecules. While all molecules are attracted to each other, some attractions are stronger than others. Non-polar molecules are attracted through a London dispersion attraction; polar molecules are attracted through both the London dispersion force and the stronger dipole-dipole attraction. The dipole-dipole attraction is often thought of as 'opposite charges attract; like charges repel.' The force of attractions between molecules has consequences for their interactions in physical, chemical and biological applications.

This is lesson to begin learners' thinking about magnetic influence. Learners will watch a classroom demonstration about the effect of magnets on iron filings and then complete a journal assignment to record their reactions and thoughts. This is the first activity in the Mapping Magnetic Influence educators guide.

Explore the pattern of earthquakes on Earth, including magnitude, depth, location, and frequency.

Our school, Kelly Middle School, is one of the oldest middle school buildings in 4J (primary construction was completed in 1945). Each year we practice earthquake drills. Why? Why should we be concerned about earthquakes? Where might an earthquake occur in the northwest area? Might it be minor or violent? How might this be measured? Is an earthquake a singular event, or a series of events? What increases or decreases an earthquake hazard? Do we have any early-warning systems? Is the school earthquake drill correct? Considering these questions students need to develop an understanding of how to prepare for, and react to an earthquake event. When students are comfortably informed, who should they report to?
