In this activity, students learn which characteristics make a species more likely to be “at-risk” of extinction, then practice analyzing the traits of at-risk animals.
In this activity, students explore the web-based U.S. Forest Service Climate Change Atlas to learn about projected climate changes in their state and how suitable habitat for tree and bird species is projected to change by 2100.
These graphs show carbon dioxide measurements at the Mauna Loa Observatory, Hawaii. The graphs display recent measurements as well as historical long term measurements. The related website summarizes in graphs the recent monthly CO2, the full CO2 Record, the annual Mean CO2 Growth Rate, and gives links to detailed CO2 data for this location, which is one of the most important CO2 tracking sites in the world.
This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.
This image depicts a representative subset of the atmospheric processes related to aerosol lifecycles, cloud lifecycles, and aerosol-cloud-precipitation interactions that must be understood to improve future climate predictions.
In nature most elements occur as a mixture of two or more isotopes. Eachisotope of an element has a fixed mass with a natural percent abundance. The mass of theelement needs to reflect the masses of these isotopes in their respective abundances. Giventhe masses and abundances, how is the Average Atomic Mass determined?
In this activity, you will determine the atomic mass of the fictitous element Candium.
Both of these lessons are classroom activities that require students to build models that display understanding of atoms and molecules. One lesson is structured while the other is guided.
In this lesson, the students will discover the relationship between an object's mass and the amount of space it takes up (its volume). The students will also learn about the concepts of displacement and density.
This video shows where and how ice cores are extracted from the West Antarctic Ice Sheet. The cores are cut, packaged, flown to the ice core storage facility in Denver, further sliced into samples, and shipped to labs all over the world where scientists use them to study indicators of climate change from the past.
In this simulation of a doctor's office, students play the roles of physician, nurse, patients, and time-keeper, with the objective to improve the patient waiting time. They collect and graph data as part of their analysis. This serves as a hands-on example of using engineering principles and engineering design approaches (such as models and simulations) to research, analyze, test and improve processes.
These 3 word problems require students to solve addition and subtraction problems.
We use motion detectors and a bowling ball to find relationships velocity, mass, and energy.
Students explore area as an attribute of two-dimensional figures and relate it to their prior understandings of multiplication. Students conceptualize area as the amount of two-dimensional surface that is contained within a plane figure.
In this lesson, students analyze a daring challenge to the legal and social order of the time: Susan B. Anthony’s casting of an illegal ballot in the 1872 presidential election. Anthony was ultimately put on trial, convicted, and fined $100 for her “crime.” In this lesson, students close read an excerpt from Anthony’s speech Is It a Crime for Women to Vote? in which Anthony defended her actions. The speech, written prior to Anthony’s trial in 1873, contains many themes that resonate with contemporary debates about membership in American society. At a time when voter suppression, gerrymandering, and election interference dominate the headlines, this lesson prompts students to draw connections between the past and present, especially around acts of civil disobedience, the role of voting in a democracy, and the meaning of equality.
What drives changes to classic myths and fables? In this lesson students evaluate the changes Disney made to the myth of "Hercules" in order to achieve their audience and purpose.

In this lesson, students are introduced to audio engineers. They discover in what type of an environment audio engineers work and exactly what they do on a day-to-day basis. Students come to realize that audio engineers help produce their favorite music and movies.
In this oral history from the Birmingham Civil Rights Institute, Audrey Hendricks recalls her arrest and jailing at the age of nine for participation in the Children's Crusade of 1963.
Students use their emerging writing skills to write shopping lists. They work within a budget, use problem-solving skills to create lists, and buy their favorite treats at the class store.
Students learn more about assistive devices, specifically biomedical engineering applied to computer engineering concepts, with an engineering challenge to create an automatic floor cleaner computer program. Following the steps of the design process, they design computer programs and test them by programming a simulated robot vacuum cleaner (a LEGO® robot) to move in designated patterns. Successful programs meet all the design requirements.
