Global Ups and Downs, Changing Sea Level
This unitfocuses on the concept that changes in sea level have occurred in the past, are occurring now, and will continue to occur. The unit provides an inquiry-based exploration of the lines of evidence for periodic melting of ice and resulting sea level rise: glacial evidence, geologic evidence, fossil evidence, and isotopic evidence. Students learn about the worldwide effects of sea level changes in the past and then use a study on topography and sea level to demonstrate their understanding o
Illuminations, National Council of Teachers of Mathematics Vision for School Mathematics
The National Council of Teachers of Mathematics Illuminations Web site is designed to illuminate the new vision for school mathematics as presented in NCTM s Principles and Standards for School Mathematics. The site provides online esources that will help improve the teaching and learning of mathematics for all students, from pre-school through high school.
Science Sampler : Reading science
Nonfiction books have the power to excite students about learning and fuel their desire to know more about a topic or person. Using a variety of books can differentiate instruction and provide suitable reading to students at all levels and for almost any interest. This article provides a list of recommended reading and some lesson ideas that correspond with the material.
Sounds of the Sun
The sounds of the sun are the focus of this two-minute episode of the radio program Pulse of the Planet. The episode is available here in text and audio formats, the latter of which features time-compressed sun sounds. The episode's host and his guest, a solar physicist, explain the dynamics that cause our sun to oscillate and produce sound waves. The sound data was collected by the space-based Solar and Heliospheric Observatory (SOHO). In analyzing the sun's sounds, scientists detected jet stre
Sound Waves Underwater : True or False
This interactive quiz from the NOVA Web site features an array of interesting facts about the nature of sound underwater.
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
The baby's brain : infant vision
In this feature, the user explorers how a baby's sense of sight develops. By dragging a slider bar to each of six different age markers, the user can see how the same image looks for babies as they get older. There is also a paragraph-long explanation of vision at each of the six ages shown: newborn, 1 month, 2 months, 3 months, 6 months, and adult. These explanations reveal what a baby can and cannot see at each age. They also discuss how a baby's brain and eyes mature, providing improved focus
This online tutorial from the TheTech Museum of Innovation focuses on genetics. The interactive topics will initially introduce the user to the DNA, chromosomes, and the make up of human genes. Further topics will examine forensic science, the history of forensics, fingerprinting, and cloning background research and community response to cloning. Finally, the resource provides connections to gallery exhibits, science labs, and a design challenge that engages the learner to write a persuasive let
Antarctic Extreme Jeopardy
This Antarctica activity challenges students to research and create the answers and questions for a game of classroom Jeopardy. They will include hazards to humans, polar gear, and the cold facts. This site also includes a series of inquiry-based questions to get students thinking about Antarctica and guidelines for conducting additional research, illustrated activity directions, and a worksheet that helps students craft their Jeopardy-style answers and questions.
Teacher's Toolkit : Two-tiered assessment
Developing good instruments that can be used to assess what students really know about scientific content is one of the most difficult tasks facing teachers in middle school classrooms today. However, two-tiered tests can be an effective solution to this increasing problem. Two-tiered tests are written assessments that not only ask students for an answer to a problem, but also require students to explain the reasoning behind their answer.
Quick take on the wide, wide world of geometry
As the social studies, art, and music classes in the middle school widen students horizons, some of your students may become fascinated with the art, costumes, and customs of other peoples in this and other times. The NCTM Principles and Standards calls for middle school students to be able to recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science, and everyday life.
Observe common objects made of minerals
This interactive Earth science resource lets students first see six images of minerals and then, by placing their cursor over each image, an image of an everyday object made from that mineral. Quartz, gypsum, and fluorite are among the minerals shown, with the corresponding familiar objects being glass, drywall (Sheetrock), and toothpaste. Copyright 2005 Eisenhower National Clearinghouse
Water reclamation plant
In this video clip, students see how wastewater is treated at a water reclamation plant. One of the plant's operators gives Bob the Vid Tec (a children's programming host) a tour of the plant, describing along the way what happens at each step in the water treatment process. For example, the operator explains that microorganisms are used to consume human waste in the biological nutrient removal step. Bob also talks with another plant operator about why kids should learn about wastewater treatmen
Where is ozone located in the atmosphere? This informational activity, part of an interactive laboratory series for grades 8-12, explores the changes in ozone concentration with altitude. Students are introduced to layers of the atmosphere and the amount of ozone found at each layer of the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The activity also discusses why the addition of ozone to the atmosphere at different levels determines the temperatures of those levels. Stud
What Did T. rex Taste Like?
This computer activity is an introduction to cladistics, which organizes living things by common ancestry and evolutionary relationships, enabling us to better understand life's present diversity and evolutionary history. The predictive power of cladistics can be used to answer questions that cannot be answered by observation of a living organism, such as What did dinosaurs taste like? This site presents a simplified version of the process used to generate cladistic analyses. A teacher's section
Triangle Geometry: Angles
This interactive math site teaches students about angles and triangles. There are interactive activities for measuring angles, exploring types of angles, and adding angles. By using a Java applet and pictures, a proof of the Pythagorean Theorem is demonstrated.
Observe a visual model of Earth's spheres
This Earth science resource enables students to view Earth's four spheres--the geosphere, hydrosphere, biosphere, and atmosphere. The visualization is introduced by a paragraph that defines the four spheres. Below the paragraph, there is an image of a globe that a viewer can animate by clicking on it. The globe separates into four globes, each of which shows one sphere and is labeled with the appropriate sphere name. The animation contains a legend to explain the color coding used. Controls allo
How come y = mx + b has to be that way?
Observe the retreat of ice sheets from North America
In this Earth science animation, middle and high school students observe the retreat of ice sheets in North America for the past 18,000 years. Students are instructed to observe the animation carefully to see how the sea level changes as the ice sheets retreat. The animation presents images in 1,000-year increments from 18,000 years ago to the present. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to analyze how the shape of the
