There are two types of catalysis reactions: homogeneous and heterogeneous. In a homogeneous reaction, the catalyst is in the same phase as the reactants. In a heterogeneous reaction, the catalyst is in a different phase from the reactants. This activity addresses homogeneous catalysis.

This is an activity about image comparison. Learners will analyze and compare two sets of images of the Sun taken by instruments on the Solar Dynamics Observatory spacecraft. With Set 1, they will observe the Sun in both a highly active and a minimally active state, and be able to detect active regions and loops on the Sun by comparing the two images. With Set 2, they will identify areas of high magnetic activity on a magnetogram image and recognize that these areas correspond to highly active regions on the Sun.

Students are presented with a graph of atmospheric becomes CO² values from Mauna Loa Observatory, and are asked to explore the data by creating a trend line using the linear equation, and then use the equation to predict future becomes CO² levels. Students are asked to describe qualitatively what they have determined mathematically, and suggest reasons for the patterns they observe in the data. A clue to the reason for the data patterning can be deduced by students by following up this activity with the resource, Seasonal Vegetation Changes. The data graph and a student worksheet is included with this activity. This is an activity from Space Update, a collection of resources and activities provided to teach about Earth and space. Summary background information, data and images supporting the activity are available on the Earth Update data site.

The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the country converted to mechanization, and California was no exception. One 1929 image shows young women working in a towel factory in Orange. Photographs taken in San Francisco illustrate that workers used machines to make products as different as Ghirardelli Chocolate and music rolls for automated player pianos. Images also show women working on an assembly line in a soap factory, and men sewing clothes in a shop (at a time when a good suit, cut on machines instead of by hand, retailed for $40 to $50). Automation and mechanization also changed agricultural practices. The combined traction steam harvester built by Stockton J. Barry on his California ranch was one of the machines that changed the way produce was harvested. Mechanized canning changed the way fruit and vegetables were processed and preserved, and made out-of-season produce available year round. Photographs in this group show cannery workers at tables, and cans going through a labeling machine. The introduction of mechanized food processing eventually brought a new awareness of the importance of standards for foods production. The Pure Food and Drug Act and the Meat Inspection Act were both passed in 1906. As workers nationwide adjusted to an increasingly mechanized workplace, good working conditions took on new importance. Workers in several industries formed unions (such as the Berryessa Fruit Growers formed in 1920, shown here) to promote safer working conditions and limit maximum working hours.

A selection of Library of Congress primary sources exploring charts and graphs. This set also includes a Teachers Guide with historical context and teaching suggestions.

This kit is a historical overview of American representations of chemicals from the three sisters to the Love Canal. It compares conflicting constructions about nuclear reactor safety, depleted uranium, Rachel Carson and DDT. Through analyzing diverse historic and contemporary media messages, students understand changing public knowledge, impressions and attitudes about chemicals in the environment.

In twenty-first century American society, childhood is popularly understood as a time of innocence, learning, and play. At the end of the nineteenth century, however, children made up part of the country’s workforce, and labored on farms and in factories. When they were not working, they enjoyed great independence in leisure activities—be it in a loud city street or a peaceful country lake. Often, children were far from adult supervision. Reformers during the Progressive Er—a period of social activism and political reform across the United States between the 1890s and 1920s —took a great interest in child welfare. Through organizations and legislation, they sought to define what a happy and healthy childhood should be in the modern age. Immersion in nature was central to what the Progressives prescribed, and children’s organizations and camps offered a suitable combination of supervision and open spaces. The formula for a healthy childhood was further refined in postwar America. Children were given a distinct place in the family and home, as well as within the consumer market with the emergence of teenage culture and buying power. This exhibition was created as part of the DPLA's Public Library Partnerships Project by collaborators from the Digital Library of Georgia and Georgia's public libraries.

In this video clip from Earth: The Operators' Manual, host Richard Alley discusses China's efforts to develop clean energy technologies and to reduce CO2 in the atmosphere, by building coal plants using CO2 sequestration technology. (scroll down page for video)

The City X Project is an international educational workshop for 8-12 year-old students that teaches creative problem solving using 3D printing technologies and the design process. This 6-10 hour workshop is designed for 3rd-6th grade classrooms but can be adapted to fit a variety of environments. Read a full overview of the experience here: http://www.cityxproject.com/workshop/

In this short video, learn about actions that humans can take to mitigate climate change and adapt to its impacts. Use this resource to stimulate thinking and questions about climate change and to provide opportunities for students to design solutions and communicate information.

This video discusses how the populous areas west of the Andes are largely desert and rely on glacial meltwater as an important source of fresh water. Because the Peruvian glaciers high in the Andes are in rapid retreat, scientists are monitoring the steadily shrinking glaciers and the impact of their reduction on local populations.

This video focuses on the science of climate change and its impacts on wildlife on land and in the sea, and their habitats in the U.S. There are short sections on walruses, coral reefs, migrating birds and their breeding grounds, freshwater fish, bees, etc. Video concludes with some discussion about solutions, including reduce/recycle/reuse, energy conservation, backyard habitats, and citizen scientists.

This video addresses how climate change is affecting the biomes and ecosystems in the US Pacific Northwest, Alaska, Hawaii and the Caribbean Islands. It also highlights the impacts on infrastructure and defines key climate science terms.

This series of 7 captioned images depict sources, causes and results of carbon dioxide and greenhouse gas emissions. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.
