Observe an exploded star at different wavelengths
This Earth science resource enables students to observe and compare the appearance of the Crab Nebula under different wavelengths. The introduction explains how the nebula is the remains of an exploded star (supernova). It also reveals how temperature variations in the nebula are detected by different wavelengths. Students are instructed to move the cursor across the spectrum to see images of the nebula captured using radio and microwaves; infrared, visible, and ultraviolet light; and gamma rays
Gravity Gets You Down
This site has students understanding that: 1) Without air resistance, all objects would fall at the same acceleration, regardless of mass. 2) Gravity is the force that causes objects to fall. 3) Air resistance, a type of friction, works against gravity to decrease the acceleration of a falling object. Included in this two day lesson plan are the objectives, needed materials, procedures, adaptations for older students, discussion questions, a rubric for assessment, extension activities, suggested
Variation about the mean
This workshop session, part of a free online course developed for elementary and middle school teachers, explores the mean in depth. Participants work together to investigate the mean as the balancing point of a data set and come to understand how to measure variation from the mean. Video segments, interactive practice, problem sets, and discussion questions involve participants in active exploration.
Insights into Algebra 1 : Teaching for learning
This is an eight-part video, print, and Web-based professional development workshop for middle and high school teachers. Participants will explore strategies to improve the way they teach 16 topics found in most Algebra 1 programs. In each session, participants view online videos that showcase effective teaching, then engage in activities designed to help them examine their teaching practice, incorporate what they are learning into their practice, share their experiences with other teachers, and
English Language Learners in the Science Classroom
What can we as teachers do to help English Language Learners (ELLs) learn science when we do not speak their languages or know their cultures? Both pre- and in-service teachers have successfully used the following strategies in teaching in teaching language and cultural minorities. These strategies can be, and often are, used by ESL (English as a Second Language) teachers in pull-out programs.
Students Take Center Stage in Classroom Assessment
Using the example of Shelburne Community School in Shelburne, Vermont, the authors emphasize the importance of involving students and parents in assessment and portfolio processes.,Volume 5, Number 2
Quick take on Pheonix Mission to Mars : follow the water
Following water continues to guide exploration even as space is explored find water and you might find life itself. One such mission that is following the water is the Phoenix Mars Lander project. On August 4, 2007, the lander was launched on its 10-month journey to the Red Planet. Phoenix will land on the northern plains of Mars and dig into the soil and water-ice seeking the Martian Holy Grail: water and possible life-supporting conditions.
How Students Learn: Mathematics in the Classroom
This book, available online free in pdf format, builds on the discoveries detailed in the best-selling How People Learn. The authors aim to present these findings in a way that teachers can use immediately, to revitalize their work in the mathematics classroom for even greater effectiveness. The general theme is teaching math to generate real insight and reasoning in math students. It also features illustrated suggestions for classroom activities.
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
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.
PhysLink
