This printable guide is to be used in conjunction with the African Vision web site from the NMAfA. It offers six different activites to try on your own including connections between art and science as well as some games.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Explain how electromagnetic waves differ from sound waves
Trace the path of light through the eye to the point of the optic nerve
Explain tonic activity as it is manifested in photoreceptors in the retina

Students examine the structure and function of the human eye, learning some amazing features about our eyes, which provide us with sight and an understanding of our surroundings. Students also learn about some common eye problems and the biomedical devices and medical procedures that resolve or help to lessen the effects of these vision deficiencies, including vision correction surgery.

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided.

A tutorial on the electromagnetic and visible spectra. Discusses dispersion and how perceptions of white and black are related to the visible light spectrum.

Zoologist Dan-Erik Nilsson demonstrates how the complex human eye could have evolved from simple light-sensitive cells. From a PBS show called "Evolution: Darwin's Dangerous Idea." Includes background reading material and discussion questions. [4:08]

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

Students are introduced to the Robotics Peripheral Vision Grand Challenge question. They are asked to write journal responses to the question and brainstorm what information they require to answer the question. Their ideas are shared with the class and recorded. Then, students share their ideas with each other and brainstorm any additional ideas. Next, students draw a basis for the average peripheral vision of humans and then compare that range to the range of two different focal lengths in a camera. Through the associated activity provides, students see the differences between human and computer vision.

Students learn about how ultrasonic sensors work, reinforcing the connection between this sensor and how humans, bats and dolphins estimate distance. They learn the echolocation process sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects. Two mini-activities, which use LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors, give students a chance to experiment with ultrasonic sensors in preparation for the associated activity. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, and details about the LEGO ultrasonic sensor. Pre/post quizzes are provided. This lesson and its associated activity enable students to gain a deeper understanding of how robots can take sensor input and use it to make decisions via programming.

This educator guide is designed for young adults on the verge of making important life decisions, defining who they are, and determining how to achieve their hopes and dreams. Short film modules and highly customizable lesson plans allow educators or youth group leaders to spark meaningful dialogue with teens and young adults, and encourage them to develop a richer understanding of themselves and their possible futures.

Shmuly Yanklowitz is an intellectual rabbinical student at New York City's Yeshivat Chovevei Torah Rabbinical School and a passionate activist. A Modern Orthodox Jew, he feels compelled to break boundaries, to resist becoming an old-style rabbi stuck within the walls of the synagogue. A lesson plan and discussion guide for teachers are included.

Tahera Ahmad is an outspoken young woman from a traditional Pakistani-American family. She is a coach and mentor for Muslims in high school while studying to be an Islamic chaplain. A trip to Egypt takes her out into the world for the first time, where she reflects on being a leader. A lesson plan and discussion guide for teachers are included. [10:48]

This site from FamilyDoctor.org provides great information on conjunctivitis, or pinkeye. General information on the illness is given, along with facts about signs and symptoms of pinkeye. Links are provided throughout the article for additional information on related subjects.

How do we see what we see? The eye works all day from the moment you wake up to the moment you close them to go to sleep. Let's take a tour of the amazing eye! Included is a video, an article, quiz, activity and word find.

Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between the additive and subtractive color systems via predictions, observations and analysis during three demonstrations. These topics help students gain a better understanding of how light is connected to color, bringing them closer to answering an overarching engineering challenge question.
