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.

In this video segment adapted from Northwest Indian College, Lummi Elders explain how a decline in the availability of salmon reflects a threatened environment that must in some way be protected.

This activity features video segments from a 2007 PBS program on solar energy. Students follow a seven-step invention process to design, build, and test a solar cooker that will pasteurize water. In addition, they are asked to describe how transmission, absorption, and reflection are used in a solar cooker to heat water and to evaluate what variables contribute to a successful cooker.

Easy to read and use website for kids. Great for more than just biology! Not very in depth but could be useful if doing a mini project.

This subject exposes students to a variety of visualization techniques so that they learn to understand the work involved in producing them and to critically assess the power and limits of each. Students concentrate on areas where visualizations are crucial for meaning making and data production. Drawing on scholarship in science and technology studies on visualization, critical art theory, and core discussions in science and engineering, students work through a series of case studies in order to become better readers and producers of visualizations.

In this 5-lesson multi-media unit, students will explore various real-world applications of different forms of measurement, including time and distance. They will make estimations and calculations. Throughout the unit, students will be using online resources to familiarize themselves with coral reefs, the nation of Belize, and to plan a pretend scuba diving trip. Activity sheets (pdf), links to online resources, assessment options and other commentary are provided.

Video and animations of sea level from NASA's Climate website. Since 1992, NASA and CNES have studied sea surface topography as a proxy for ocean temperatures. NASA Missions TOPEX/Poseidon, Jason 1 and Jason 2 have been useful in predicting major climate, weather, and geologic events including El Nino, La Nina, Hurricane Katrina, and the Indian Ocean Tsunami.

In this activity, students use NASA satellite data to explore the seasonal changes in sea surface temperatures of the Gulf Stream. Students use NASA's Live Active Server (LAS) to generate data of sea surface temperatures in the Gulf Stream, which they then graph and analyze.

In this video segment adapted from the College of Menominee Nation, tribal members share examples of how seasons are changing, and how these changes are affecting local plants.

DQ: How do plants get lightThis is a lesson that can be used with second grade science around the time or before the students conduct the investigation on whether plants need light to survive. The students will learn to work collaboratively and trust their own experiences about plants and engage in a modeling activity. This lesson has been edited to add the Cultivating Genius Framework by Gholdy Muhammad to the lesson. Pursuits addressed : Intellectuality, skills  

In this lesson, based on the documentary Through My Eyes: The Charlie Kelman Story, students learn about the history and state-of-the-art of one of the world's most commonly performed surgical procedures--eye cataract removal and replacement.

Dope the semiconductor to create a diode. Watch the electrons change position and energy.

This video segment adapted from Northwest Indian College reveals how Native American life and knowledge is connected to natural cycles.

Like many other industries, shoe manufacturing changed in the early 19th century. Previously, most shoemakers worked in their homes or small workshops (called ten-footers")

Who invented the computer? Like many important technological developments, the invention of the computer cannot rightly be attributed to a single person. It is clear, however, that World War II was crucial to the emergence of the electronic digital computer. The first general-purpose electronic computer was the Electronic Numerical Integrator and Computer, the ENIAC, sponsored by the U.S. Army's Ballistics Research Laboratory at the Aberdeen Proving Ground in Maryland and developed at the the Moore School of Electrical Engineering at the University of Pennsylvania. The leaders of the project were physicist John W. Mauchly and a young electrical engineer, John Presper Eckert. In this interview, done in 1988 by David Allison and Peter Vogt for the Smithsonian Institution, Eckert described how the war provided "the opportunity"and the money to solve "engineering problems, scientific problems in general"that interested them.

In this video excerpt from NOVA, learn about the advantages, disadvantages, and ethical implications of screening for genes associated with diseases, including those linked to breast and ovarian cancers.

Why do the lights turn on in a room as soon as you flip a switch? Flip the switch and electrons slowly creep along a wire. The light turns on when the signal reaches it.

This video segment from IdahoPTV's D4K lists, describes and shows examples of the 6 simple machines and how they make work easier.

In this lesson designed to enhance literacy skills, students learn how animals' physical characteristics, such as jaw structure, are directly related to the function they perform when the animal interacts with its environment.

Discusses social, ethical and clinical issues associated with the development of new biotechnologies and their integration into clinical practice. Basic scientists, clinicians, bioethicists, and social scientists present on four general topics: changing political economy of biotech research; problems associated with the adaption of new biotechnologies and findings from molecular biology for clinical settings; the ethical issues that emerge from clinical research and clinical use of new technologies; and the broader social ethics associated with investigations of population genetics and social problems. Use of cases and recent literature.
