In this learning activity, students compare changes in insolation with changes in surface temperature in the polar regions using scientific visualizations of global data sets. Links to readings related to the shrinking ice cap and albedo are included. This is part 1 of a four-part activity on polar science. Extension activities examining air and sea surface temperature in relation to changing Earth albedo are included. This activity is one of several learning activities connected with the 2007 GLOBE Earth system poster.

In this video segment adapted from A Science Odyssey, follow two scientists and their Nobel Prize-winning efforts to cure bacterial infections using penicillin.

This online article is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. "Profile: Albert Einstein," part of the Frontiers in Physical Science seminar, briefly covers Einstein's life and work including his Special Theory of Relativity and the paper that gave the world E=mcĺ_, his Nobel Prize in Physics, his influence yet exclusion from the Manhattan Project, and his promotion of peace and human rights.

The 1935 edition published by R. T. Gunther was based on only three or four local manuscripts, and as such is defective in many places. Missing phrases, or mis-copies or mis-read phrases at times makes that text unintelligible.

This edition is based on the collation of a significant number of manuscripts (over 80, and eventually, it is hoped, all manuscript copies). What is now being published here is the text of the Prologue and of the first sixteen chapters (Version 1.1).

The edition is available in five PDF files:

Part I: Introduction contains the preface and introductory material, including manuscript information;

Part II: Critical Edition contains the Latin text and diagrams, the critical apparatus and a facing English translation;

Part III: Latin Text contains the Latin text and diagrams, without the apparatus criticus, but maintaining the line numbers of the critical edition;

Part IV: English Text contains the English text and diagrams, for those who are interested in consulting only the translation.

Appendix I: Catalogue of Stars contains information about the all the stars mentioned in the text.

Over time these texts will be updated and expanded, when the remaining manuscript copies are collated, and when the editing of further sections have been completed. However, it is not expected that the present version will change – the rest of the manuscripts will expand the apparatus criticus but are unlikely to modify the text itself.

The editor is interested in the receiving comments on the text, and further insights into its interpretation, from others. He is willing to incorporate such additions into future versions for the benefit of others who would consult this edition in the future. Comments can be sent to thomson@chass.utoronto.ca.

This is a lesson about generating hypotheses and testable questions. Learners will use critical thinking and a collaborative approach to pose questions related to the study of Mars and evaluate the quality of their questions. They will explore remote-sensing data collected by a camera orbiting Mars - the Thermal Emission Imaging System (THEMIS) and develop a team science question. Students will practice critical thinking skills, use a collaborative approach to this first critical step of the scientific process. Exploring the images of the surface of Mars in Visible (VIS) images, students will come up with a topic of study, their team science question and hypotheses. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.

This subject introduces the history of science from antiquity to the present. Students consider the impact of philosophy, art, magic, social structure, and folk knowledge on the development of what has come to be called “science” in the Western tradition, including those fields today designated as physics, biology, chemistry, medicine, astronomy and the mind sciences. Topics include concepts of matter, nature, motion, body, heavens, and mind as these have been shaped over the course of history. Students read original works by Aristotle, Vesalius, Newton, Lavoisier, Darwin, Freud, and Einstein, among others.

In this activity, students are introduced to the concept of remote sensing. In the course of this experiment, students will investigate heat conduction on two surfaces and understand the application of these techniques to spacecraft investigations of surfaces in the solar system. Materials required for the outdoor demonstration include a cement step, sand, laboratory thermometers, foam rubber, and a meter stick. An optional indoor experimental set up uses twin desk lamps with equal-wattage tungsten bulbs and an infrared thermometer. A student datasheet accompanies the activity. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This resource explores the cultural context of scientific inquiry through an interdisciplinary lens. Undergraduate students are invited to follow two characters from William Shakespeare’s play King Lear who debate the cosmos with various scientists from the 17th – 20th centuries, including Galileo Galilei, Isaac Newton, and Marie Curie. The joined scientific / literary lens models how intellectual questions about knowledge and analysis often draw from interrelated traditions of thought and practice, and asks students to consider the nature of their own intellectual questions. The resource is broken into five brief modules and can be completed entirely in class, or in partial increments as take-home.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts. Escapements are found in mechanical clocks, such as those driven by a pendulum or a spring. Learners will build the wrapping form of escapement said to be used in a fifteenth-century German clock.

The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system.

This video provides step-by-step instructions for collecting soil samples in the field, and for analyzing and storing soil samples in the lab. Procedures for determining the bulk density, particle density, particle size distribution, fertility, and pH of a soil are demonstrated. The resource includes a video and a written transcript, and is supported by the Soil Characterization, Lab Measurement Protocols in the GLOBE Teacher Guide. This is one of five videos about soils in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment) a worldwide, hands-on, K-12 school-based science education program.

This is a reading associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. Outside of Solar Week, information, activities, and resources are archived and available online at any time. This is a blog entry about the process by which rocket payloads are assembled prior to launch. It was written by one of the female team members associated with a NASA sounding rocket launch program. The blog entry reading is scheduled to occur during Friday of Solar Week.

This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science curriculum in grades 5 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be one-pagers with a Teacher’s Guide and Answer Key as a second page.

This site provides fun activities for children to do and make, while they learn about space and Earth science, and the technology that enables science. The Teachers Corner on the WWW site contains curriculum supplements originally published in the ITEA (International Technology Education Association) Technology Transfer Teacher magazine.

On this webpage, learners will read fun facts about Pluto and explore why it is no longer considered a planet.

This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

This video segment adapted from Shedding Light on Science uses historical illustrations and everyday examples to show that light has a speed and does not travel instantaneously.

This activity is about the use of remote sensing in planetary exploration. Learners will find out how human curiosity in planetary exploration results in science questions, engineering solutions, and teamwork. This activity demonstrates how planetary features are discovered by the use of remote-sensing techniques. Students will experience the different phases in planetary exploration, including telescope observations, fly by missions, orbiters, landers, rovers, and their own ideas about human exploration. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts and vocabulary.

This OER explores the basic operations of a Sundial. It contains both an activity as well as resources for further exploration. It is a product of the OU Academy of the Lynx, developed in conjunction with the Galileo's World Exhibition at the University of Oklahoma.

This series of ten lessons has been developed to teach students about local and global water issues. They are based on NASA’s Global Precipitation Measurement (GPM) Mission.
