This text includes 25 reading assignments for an introductory astronomy course. They have been modified from the OpenStax Astronomy 2e and College Physics 2e (linked in related resources below) textbooks to order the topics in a logical manner for a one semester course and provide shortened (~10-20 pages) readings intended for biweekly reading assignments. The text also features enhanced treatment of the Newton's Laws, Energy, and Optics content that go beyond the typical introductory astronomy course for non-majors.

Course connections: This content was built for an introductory survey of astronomy course (e.g., PHYS 103), including apparent motions of objects in the sky, light, telescopes, solar system objects, exoplanets, the sun, stars, galaxies, and cosmology. Basic math skills (arithmetic, powers, scientific notation, unit conversions) will be used frequently. This course is designed for students in all majors.

This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.

In essence, this is an opportunity for students to practice calculating trends with uncertainties to draw conclusions about whether or not there is a trend in hurricane intensity. It follows closely with the IPCC AR4 findings, and is guided so that students will know exactly what they have to do - step by step. Please see the attached document for the bulk of the activity. There are some additional instructor's notes that give a little more background on the concepts involved with confidence intervals and trends. There is also an excel file with all of the necessary data already tabulated for the exercise - so you don't need to go find it yourself unless you want to.

This activity is a set of student-centered exercises that enable students to learn about the individual stories of Goldman environmental prize winners, the activism and organizing that grounds their work, and the underlying political and social contexts from which their struggles emerge. The lesson inspires critical reflection about justice, power, and democracy in green politics, and encourages ways to make personal connections to activism and environmental work.

Students learn how roadways are designed and constructed, and discuss the advantages and limitations of the current roadway construction process. They look at current practices of roadway monitoring, discuss the limitations, and consider ways to further road monitoring research. To conclude, student groups compete to design smooth, cost-efficient and sound model road bases using gravel, sand, water and rubber (representing asphalt). This lesson prepares students for the associated activity in which they act as civil engineers hired by USDOT to research through their own model experimentation how to best use piezoelectric materials to detect road damage by showing how piezoelectric transducers can indicate road damage.

This video segment highlights how the U.S. military is the single largest user of energy in the nation, but it is also trying to reduce its carbon bootprint. Scenes taped at Fort Irwin and Camp Pendleton show the Army and Marines experimenting with wind and solar in order to reduce the number of fuel convoys that are vulnerable to attack.

This module is a brief introduction to making a distinction between kinetic and potential energy.  The laws of potential energy inform many of our definitions later in chemistry and are especially useful when related specifically to charges.

In this lesson, students are introduced to both potential energy and kinetic energy as forms of mechanical energy. A hands-on activity demonstrates how potential energy can change into kinetic energy by swinging a pendulum, illustrating the concept of conservation of energy. Students calculate the potential energy of the pendulum and predict how fast it will travel knowing that the potential energy will convert into kinetic energy. They verify their predictions by measuring the speed of the pendulum.

Students annotate a photograph of their local study site and then develop a more abstract diagram of the site that highlights the flow of energy and matter among the four components of the Earth system. The investigation concludes with students sharing their diagrams and creating a single class diagram to represent their study site.

After completing this investigation, students will be able to:

- analyze a photograph of their local study site with respect to Earth systems;
- annotate interconnections among components of the Earth system on a photograph;
- translate their analysis of their study site into a diagram of energy and matter flow among components of the Earth system; and
- interpret and evaluate diagrams of their local study site.

Students have been examining Earth as a system of interacting parts, initially from the local perspective but more recently from the regional and global perspectives. In order to fully understand the Earth as a system and how its components interact with each other, students need to consider change over time. On relatively short times scales, these changes are related to the fact that the solar energy that drives the Earth system passes through an atmosphere that varies across space and time before reaching a spinning sphere. Across longer seasonal and annual time scales, these changes are more specifically related to the differential heating that results from the tilt of Earth's axis and Earth's orbit around the sun. At this longer-term global scale, it may be easier to see the repeating patterns of change across space and time and to infer how changes in one sphere may be linked to changes in others.

Students explore issues related to the rapid intensification of hurricanes. They become familiar with the concepts of heat energy and the specific heat of water and interact with animations of sea surface temperature images to identify the Gulf Stream and the Loop Current. Students use NOAA View and Google Earth, free data-image tools, to explore visualizations of heat content in the Gulf of Mexico just before Hurricane Katrina. The examine a plotted path of Katrina as an overlay on these visualizations and observe changes in the heat content of Gulf waters as the hurricane passed over it.

In this physical geography lab, students examine the relationship between solar altitude, solar declination, and temperature regimes. Using data collected in the field, mathematical relationships, and temperature records available on the Internet, students compare the insolation and climate in their location to that of other locations.

The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.
