Student-centered focus

This book is written to help students understand the big picture rather than get lost in random factoids to memorize. The language is accessible and inviting. Helpful diagrams and summary tables review and encapsulate the ideas being covered. Each chapter contains interactive group activities you can assign to help students work in teams and pool their knowledge.

Interactive online resources

Interesting “Links to Learning” are scattered throughout the chapters, which direct students to online animations, short videos, or enrichment readings to enhance their learning. Also, the resources listed at the end of each chapter include links to websites and other useful educational videos.

Feature boxes that help students think outside the box

A variety of feature boxes within the chapters connect astronomy to the students’ other subjects and humanize the face of astronomy by highlighting the lives of the men and women who have been key to its progress. Besides the math examples that we’ve already mentioned, the boxes include:

  • Making Connections. This feature connects the chapter topic to students’ experiences with other fields, from poetry to engineering, popular culture, and natural disasters.
  • Voyagers in Astronomy. This feature presents brief and engaging biographies of the people behind historically significant discoveries, as well as emerging research.
  • Astronomy Basics. This feature explains basic science concepts that we often (incorrectly) assume students know from earlier classes.
  • Seeing for Yourself. This feature provides practical ways that students can make astronomical observations on their own.

End-of-chapter materials to extend students’ learning

  • Chapter Summaries. Summaries give the gist of each section for easy review.
  • For Further Exploration. This section offers a list of suggested articles, websites, and videos so students can delve into topics of interest, whether for their own learning, for homework, extra credit, or papers.
  • Review Questions. Review questions allow students to show you (or themselves) how well they understood the chapter.
  • Thought Questions. Thought questions help students assess their learning by asking for critical reflection on principles or ideas in the chapter.
  • Figuring For Yourself. Mathematical questions, using only basic algebra and arithmetic, allow students to apply the math principles given in the example boxes throughout the chapter.
  • Collaborative Group Activities. This section suggests ideas for group discussion, research, or reports.

Beautiful art program

Our comprehensive art program is designed to enhance students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs. Here are a few examples.

How a pulsar beam sweeps over earth.

Model of a Pulsar. In this illustration the Earth is drawn below center, in the path of an approaching “Beam of particles and radiation”. The pulsar, labeled “Neutron star”, is drawn at upper right as a blue sphere. Its rotation axis is drawn vertically upward, with a counter-clockwise arrow around it indicating the direction of rotation. The magnetic field lines are drawn in a plane perpendicular to the rotation axis as concentric red ellipses on either side of the star. The field lines intersect the surface of the star at the “North magnetic pole”, which faces Earth, and the “South magnetic pole”, which faces toward upper right. The beam of radiation is emitted from the poles of the magnetic field, and extend toward upper right and lower left.

Structure of the milky way galaxy.

Map of the Milky Way Galaxy. Over-plotted on this data-based illustration of the Milky Way is a coordinate system centered on the Sun, which is located about half way from the center and the bottom of the image. It is a polar coordinate system, with zero degrees straight up from the Sun, 90O to the left, 180O straight down and 270O to the right. Distances are shown as circles of increasing radius centered on the Sun. Distances from 15,000 ly to 75,000 ly are indicated in increments of 5,000 ly. Moving outward from the Sun along the zero degree line are the “Near 3kpc Arm”, “Far 3 kpc Arm” and the “Sagittarius Arm”. Moving outward from the Sun along the 330O line (to the right of zero) are the “Norma Arm” and the “Scutum-Centaurus Arm”. Moving outward from the Sun along the 90O line are are the: “Orion Spur”, “Perseus Arm” and the “Outer Arm”.

Two aspects of plate tectonics.

Illustration of Rift and Subduction Zones. The upper panel shows a rift zone beneath an ocean. At left is a vertical scale of 100 km, from the ocean surface down to the top of the mantle’s partially melted zone, which is labeled at the bottom of the diagram. At top center the mid-ocean rift zone is shown, with arrows pointing left and right indicating the direction of plate motion. Directly below the rift zone magma rises up to fill the spaces and cracks between the separating plates, creating mountains and volcanoes. At far right, the thickness of the crust is indicated, consisting of the basalt from the volcanoes and sediment from their erosion. The thickness of the lithosphere is also shown, from the ocean surface down to the top of the mantle’s partiallyh melted zone. Finally, at the left and right portions of the illustration the older rocks are labeled, with arrows pointing away from the rift zone. The further from the rift, the older the rocks. The lower panel shows a subduction zone beneath an ocean. At left is a vertical scale of 100 km, from the ocean surface down to the top of the mantle’s partially melted zone, which is labeled at the bottom of the diagram. At top center the oceanic trench is labeled. To the right of the trench ocean crust and sediments are indicated, with arrows pointing left showing the motion of the crust toward the trench. At the trench, the ocean crust is forced beneath the continental crust, which is labeled on the left of the diagram. The ocean crust moves down toward the partially melted zone. As it does so, the melting ocean crust becomes hot enough to rise up to the surface (to the left of the trench in this diagram) and create the volcanoes of an island chain. At far right the thickness of the lithosphere is shown, from the ocean surface down to the top of the mantle’s partially melted zone.

Pluto close up.

Communication is effective because it allows individuals to share ideas, thoughts, and information with others.

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
