This Planet Really Rocks
This ThinkQuest Junior site contains information and activities about rocks and minerals. Included is information about what a rock is, the major characteristics with examples of sedimentary, metamorphic, and igneous rocks, the rock cycle, the differences between rocks and minerals, how to identify minerals (color, luster, streak, cleavager, hardness, and specific gravity), and the Mohs Scale. Facts about common minerals and their properties, how rocks and minerals are important, and their uses
Geometry Construction Reference
The basics of compass and straightedge construction, with notes about The Instruments and What is a construction? Construct the perpendicular bisector or the midpoint of a line segment; given a point on a line, construct a perpendicular line through the given point; given a point not on a line, construct a perpendicular line through the given point; construct the bisector of an angle; an angle congruent to a given angle; a line through a given point, parallel to a given line; an equilateral tria
Improving Mathematics Education: Resources for Decision Making
This report has been designed to help inform stakeholders about the decisions they face, to point to recent research findings, and to provide access to the most recent thinking of experts on issues of national concern in mathematics education. The essence of the report is that information is available to help those charged with improving student achievement in mathematics. It can guide those who make decisions about content, learning, teaching, and assessment. Eight important documents were revi
Visualizing the Metric System
What are some common things that could be used to approximate lengths for a visual picture of the different lengths in the metric system?
The Pythagorean Theorem
This math site has students try to figure out the Pythagorean Theorem by themselves. Included are review pages, five clues to help them find the relationship, a section that compares their results to other students, a section that gives historical information, and examples and activities for students to solve. Each clue page allows students to check to see if they have the formula correctly relating to the three sides of the right triangle. A template page that contains figures used in three of
Minerals
This site provides an in-depth look at mineral properties and identification. An alphabetical listing of common minerals allows the user to see a picture and view physical properties of the particular mineral. Properties of minerals are explained, including cleavage, hardness, crystal form, and luster. There are also downloadable labs for crystal models and mineral data sheets. Dichotomous and hardness keys are given for easier mineral identification.
Drift Seeds And Drift Fruits : Seeds That Ride The Ocean Currents
This essay explores seed dispersal by water and describes some of the physical adaptations that evolution has produced in the seeds and fruits that travel this way. There is a background essay, discussion questions, state and national standards, and links to related Teacher's Domain resources.
Simple Plot
This applet allows the user to input a series of (x,y) ordered pairs and plot them either as a connected function or unconnected data points.
When did the Grand Canyon begin to form?
This March 14, 2008 entry in the NSDL Expert Voices blog Connecting News with National Science Education Standards deals with the recent finding suggesting the Grand Canyon is two to three times older than commonly believed. Additional links to teaching resources related to earth systems structure, rock dating and the nature of science are provided.

Science Sampler : Thriving in the co-taught classroom
Classrooms are becoming more diverse as students with specific learning needs are moved out of self-contained special education classrooms and into mainstreamed classrooms with their non-disabled peers. The use of the co-teaching model allows for extensive flexibility in structuring instructional activities and responding to the needs of diverse learners. This article provides a summary of co-teaching practices that have been effective and beneficial for many years.
Population Growth in Yeasts
This lesson is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arose during the first lesson and its associated activity, in this lesson students work in small groups to design experiments that will determine how environmental factors affect yeast population growth.
Compare Human-made Objects with Natural Objects
In small groups, students will experiment and observe the similarities and differences between human-made objects and nature. The students will compare the function and structure of hollow bones with drinking straws, bird beaks, tool pliers, bat wings and airplane wings. A classroom discussion can be held to discuss similarities and differences that were observed along with follow up assessment activities such as journal writing and Venn diagrams.
Micromechnical Biosensors and their Integration with Aptamer-based Receptor Molecules
This site is one of many on \\\\\\\"nanoHUB.org\\\\\\\" which highlights availability of on-line simulations. This particular one provides a video of a research seminar on the topic of micromechanical biosensors focusing on aptamer-based receptor molecules. The quality of the graphics in the video is not high - mainly, the smallness of the visuals makes it difficult to decipher the contents. However, the information content, as delivered and described verbally, is coherent and useful. The i
GoNU.TV Game Recap - Baseball vs. Boston College - March 29, 2011
The Northeastern University baseball team defeated the Boston College Eagles in an extra inning affair Tuesday afternoon, claiming a 2-1 victory at Friedman Diamond in Brookline, Mass.
Panel: "Clearing the Air: Managing Air Quality to Benefit Health and Climate in India"
Sarath Guttikunda, assistant professor at Desert Research Institute and founder of Urban Emissions.Info in India; William K.M. Lau, chief of the laboratory for atmospheres at NASA's Goddard Space Flight Center and senior science adviser to the Hong Kong Observatory; and Danielle Meitiv, climate specialist at the Clean Air Task Force, will discuss this topic.
What Is Bullying?
In this short video, bullying is defined with facts and stats. Some key elements are power imbalance with intent to harm physically or verbally. This would be a good resource for a teachable moment in the classroom or for a guidance session on reminding students about what bullying is. Content is appropriate for upper elementary. (0:45)
Donald in Mathmagic Land part 1 of 3 In this popular educational cartoon from Disney (1959), Donald learns about Pythagoras, geometical shapes such as the golden rectangle and the pentagram, and more.
