This activity is a classroom and schoolyard investigation where students collect daily temperature and precipitation readings, weather observations, and weekly phenology reports in a phenology binder and in nature journals. Students then analyze this data and compare to recorded values in the Weatherguide calendar.

Students use bearing measurements to triangulate and determine objects' locations. Working in teams of two or three, they must put on their investigative hats as they take bearing measurements to specified landmarks in their classroom (or other rooms in the school) from a "mystery location." With the extension activity, students are challenged with creating their own maps of the classroom or other school location and comparing them with their classmates' efforts.

Students learn about gear ratios and power by operating toy mechanical cranes of differing gear ratios. They attempt to pick up objects with various masses to witness how much power must be applied to the system to oppose the force of gravity. They learn about the concept of gear ratio and practice calculating gear ratios on worksheets, discovering that smaller gear ratios are best for picking objects up quickly, and larger gear ratios make it easier to lift heavy objects.

Students use a small quantity of modeling clay to make boats that float in a tub of water. The object is to build boats that hold as much weight as possible without sinking. In the process of designing and testing their prototype creations, students discover some of the basic principles of boat design, gain first-hand experience with concepts such as buoyancy and density, and experience the steps of the engineering design process.

This video and accompanying essay examine ways to reduce the environmental impact of burning coal. Two technologies are discussed: turning solid coal into a clean-burning fuel gas (syngas), and capture and storage of CO2.

Students act as engineers contracted by NASA to create water filtration devices that clean visible particulates from teacher-prepared "dirty water." They learn about the worldwide need for potable water and gain appreciation for why water quality is an important issue for people on Earth as well as on the International Space Station. Working in groups, students experience the entire engineering design process, including a read-aloud book about the water cycle; a visiting water engineer presentation; their own online research about filter methods and designs; group brainstorming of designs (using ordinary household materials); filter construction and testing; redesign and retesting; lab book documentation of their notes, research, plans and results; and a summary poster presentation at a mini-engineering fair. Two design planning worksheets, a poster layout suggestion sheet and a grading rubric are provided.

Students observe and discuss a simple balloon model of an electrostatic precipitator to better understand how this pollutant recovery method functions in cleaning industrial air pollution.

Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Engineers design methods of removing particulate matter from industrial sources to minimize negative effects of air pollution. In this activity, students will undertake a similar engineering challenge as they design and build a filter to remove pepper from an air stream without blocking more than 50% of the air.

Posed with a paradigmatic engineering problem, students consider and explore mathematical algorithms and/or geometric concepts to devise possible solutions. The problem: How should a robotic vacuum move in order to best clean a floor of unknown shape and dimensions? They grapple with what could be a complex problem by brainstorming ideas, presenting the best idea for a solution and analyzing all presented solutions, and then are introduced to an elegant solution. Rather than elaborately calculating the most efficient route and keeping track of which tiles the robot has visited, a random number generator determines which direction the robot will take when it hits a barrier. Students are able to visually confirm how an unfamiliar programming concept (a random number generator) can make for a simple and efficient program that causes an NXT robot (that is suitably equipped) to clean a bare floor. Then students think of other uses for random numbers.

Students learn about a special branch of engineering called bioremediation, which is the use of living organisms to aid in the clean-up of pollutant spills. Students learn all about bioremediation and see examples of its importance. In the associated activity, students conduct an experiment and see bioremediation in action!

Following the steps of the engineering design process and acting as biomedical engineers, student teams use everyday materials to design and develop devices and approaches to unclog blood vessels. Through this open-ended design project, they learn about the circulatory system, biomedical engineering, and conditions that lead to heart attacks and strokes.

In this activity, students learn about the scientific evidence supporting climate change, use this information to evaluate and improve conclusions some people might draw about climate change, and participate in a role-play to negotiate solutions to climate change.

This lesson introduces click restraint, a strategy that helps students resist the urge to click on the first search result they receive in a search engine. Students learn to scan the results they receive to make an informed choice about which result to choose first.

Teacher materials, Student materials, and Presentation slides are included in this lesson.

Click! In the 1970s that word signaled the moment when a woman awakened to the powerful ideas of contemporary feminism. Today “click” usually refers to a computer keystroke that connects women (and men) to powerful ideas on the Internet. Click! aims to bridge the gap between those two clicks by offering an exhibit that highlights the achievements of women from the 1940s to the present. This exhibit explores the power and complexity of gender consciousness in modern American life.
Students will be able to explore, research, and analyze various topics such as women in politics, the Civil Rights Movement, the Feminist Movement, Body and Health, and Workplace and Family.
Educators will have the ability to retrieve lesson plans on various topics such as free lesson plans to give teachers content materials and activities that will allow them to integrate the history of the modern women’s movement into their curriculum and help students engage with important historical questions about the struggles that have made the United States more equal and democratic. Each lesson plan focuses on a historical topic that engages with the concerns of students: politics and social movements; body and health; and workplace and family. These topics are investigated through the histories of individual women, their organizations, and their struggles for greater rights and social justice. Their stories are situated within larger histories to help students connect the modern women’s movement to other changes in post-World War Two America.

This activity introduces students to global climate patterns by having each student collect information about the climate in a particular region of the globe. After collecting information, students share data through posters in class and consider factors that lead to differences in climate in different parts of the world. Finally, students synthesize the information to see how climate varies around the world.

Bell Telephone Science Hour produced this video in 1958, explaining how the production of CO2 from factories and automobiles is causing the atmosphere to warm, melting the polar ice caps, and causing the sea level to rise.

This 3-activity sequence addresses the question: "To what extent should coastal communities build or rebuild?" The activity uses social science and geoscience data to prepare an evidence-based response to the question, in targeted US coastal communities.

The video offers a simple and easy-to-understand overview of climate change. It poses basic questions such as 'What is it?' and 'How will it effect us?' and effectively answers those questions.

This video documents the effects of increasing global temperatures on biodiversity (changes in distribution, range, and numbers) and human populations. Adaptations to climate change are also outlined.
