In this activity, student teams design and conduct a scientific investigation in which they explore the conditions necessary for life. They conduct observations of environmental conditions both indoor and outdoor, and determine the range of variation they see. They compare these data with published temperature data for Earth, Mars, Pluto and Venus. The activity supports inquiry into the real world challenge of searching for life in extreme environments. The resource includes several student data sheets, data table and images, and a teacher's guide. Materials needed for this activity include weather instruments (e.g., thermometers, barometers, anemometers). This is Activity A of two activities in the first module, titled "Temperature variations and habitability," of the resource, "Earth Climate Course: What Determines a Planet's Climate?" The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

This illustration from Evolution by Monroe W. Strickberger shows the remarkable similarities between the bones in the forelimbs of various tetrapods, all of whose limbs serve very different functions.

This seminar helps the learner explore the basic concepts of life and what that means.  All life has certain things in common as well as a basic level of organization.  In this seminar you will investigate these traits and why they are important to life.StandardsBIO.A.1.1.1 Describe the characteristics of life shared by all prokaryotic and eukaryotic organisms.

Unit plans at two levels, K-grade 2 and grades 3-5 develop understanding of the issue theme, We Depend on Earth's Climate, by focusing on adaptations and environments of local plant species and polar mammals. The units are modeled after a learning cycle framework built around five key steps: Engage, Explore, Explain, Expand, and Assess. The lessons are aligned with national standards for science education and English language arts.

In this video segment adapted from the International Institute for Sustainable Development, Inuit observers describe how their traditional understanding of weather patterns is being challenged by unpredictable weather behaviors.

“Designing a dream city is easy. Rebuilding a living one takes imagination.”    -Jane Jacobs
This course examines the challenges that cities will face and strategies they can use to prepare for the impacts of climate change. Particular attention will be paid to the presence of global disparities, the needs of vulnerable populations and resource constrained locales, and the ways in which local government and community-based activities can achieve equitable levels of climate-readiness.

This comprehensive course on the visual system is designed to ground future researchers in the field of visual science and to provide scientists with an excellent basis for using the visual system as a model in research. In this graduate seminar, anatomical, neurophysiological, imaging and behavioral research is examined in an attempt to gain a better understanding of how information is processed in the primate visual system.

In this Adaptation Name Game, students sitting or standing in a circle play a version of tag, with one person in the center. When a person in the circle says another person’s name, the person in the center of the circle tries to touch the person whose name was said, before they can say someone else’s name. Later, students pause to brainstorm strategies to improve their performance, then play some more. Students learn that this was a representation of how certain structures and behaviors help organisms survive in their habitat, and that these are adaptations that species inherit over time. This game helps students learn each other’s names, while “lightly” introducing them to what adaptations are. Note: This activity is only an introduction; to gain any meaningful understanding of the topic, students will need more adaptation-focused activities, such as Adaptations Intro-Live!, Structures & Behaviors, and Related & Different, which engage students more deeply in understanding the concept through interactions with real organisms.

The three short activities in this collection explore adaptations that help whales survive in the ocean. The activities include demonstrations and experiments.
