Seismic Waves: How Earthquakes Move the Earth
Students learn about the types of seismic waves produced by earthquakes and how they move the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate the ground motions of the Earth caused by seismic waves in order to test the seismic performance of buildings.
Go Public: Osteoporosis Brochure
Students will answer the Challenge Question and use the acquired learning from Lesson 1, “Fix the Hip Challenge” and Lesson 2, “Skeletal System Overview”to construct an informative brochure addressing osteoporosis and the role biomedical engineering plays in diagnosing and preventing this disease.
Where Am I: Navigation and Satellites
How do we know where we are? What happens if you are completely lost in the middle of nowhere? Does technology provide tools for people lost in their travels? A person cannot usually determine an accurate position just by looking out a window in the middle of the ocean or vast area of land, particularly if it has not been charted before. In this lesson, students explore the concept of triangulation that is used in navigation satellites and global positioning systems designed by engineers. Also,
What is Energy?
With an introduction to the ideas of energy, students discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of energy.
Thinking Green: Grow Your Own
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. Student engagement with agriculture and gardening can not only fill a knowledge gap but also tap in to the affective domain. Students can get involved in community gardens, or collaboratively plan, plant, and cultivate a school garden, indoors, or out.
Earth on Edge : Ecosystems
This site provides information about the six ecosystems on which life on Earth most heavily depends: agricultural, forest, freshwater, grassland, coastal, and urban. It is part of a Public Broadcasting System (PBS) project, which includes a discussion guide. Ecosystems are described as communities of interacting organisms and the physical environment in which they live. The goods and services that ecosystems provide are said to form the foundation of human economies. Ecosystems purify air and wa
Guidelines for Integrating Comprehension-Based Word Study in Content Classrooms
Traditional approaches to vocabulary instruction are linear and may not help students develop deep understanding of words and retain their meanings. Vocabulary literacy is an approach to word study that engages students in word study and helps strengthen the connection between vocabulary learning and reading comprehension.
Hurricanes 2: Tracking Hurricanes
The purpose of this lesson is to examine the role of technology in identifying and tracking hurricanes. It is the second in a two-part series on the science of hurricanes and the kinds of technology being used to identify and track them. Students broaden their study by exploring how technology and science are used today to identify, measure, and track powerful tropical storms to better warn and secure people from a hurricane's often-devastating impact.
Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Addressing the Achievement Gap Through Cultural Responsiveness
To really reach students and meet their academic, social, and emotional needs, educators must know a little bit about where they came from. Going into the community and bringing the community into the classroom will help.,Volume 15, Number 1
More than Paper Load: What Does All This Student Work Tell Us?
Having faculty collaborative teams to evaluate student works is proposed in this article. The standards related to content and performance of student works should be agreed among team members. Team members should also be willing to implement change.,Volume 9, Number 3
Look Alike Liquids
In this introductory activity, students will compare the way water and isopropyl alcohol appear on different surfaces. Through the activities in this investigation, students will see that liquids have characteristic properties that can be used to identify an unknown. There is a downloadable activity sheet that will be very helpful to educators, and will help students stay on track. An assessment sheet is also available on the activity page to keep track of students progress. There is also a step
In this activity, students use and create scatterplots based on information from a table, and compare and contrast annual rainfall in various places around the world.
Polar Bears International : Wrangel Island, Russia
This site describes the ongoing research of the polar bears in the Russian High Arctic. Wrangel Island with neighboring small island, Herald Island, are the key reproductive areas for the Chukchi-Alaskan polar bear population. Marine areas and Wrangel and Herald islands provide optimum foraging habitats for polar bears, and polar bear densities in these marine habitats are high all year round. Approximately 350-500 pregnant female polar bears construct their maternity dens on Wrangel and Herald
The lemon battery challenge
In this activity, students will learn how a chemical reaction can produce electricity. Learners will create a wet-cell battery to determine how much power it takes to run an electric car.
Date a Rock
This lesson shows students that age-dating rocks involves counting atoms and comparing the counts. Students use simulated rock samples, which show a highly magnified selection of 128 atoms, each sample with a different proportion of the atoms of two different elements: a parent radioisotope, and its daughter product. By counting the parent radioactive atoms and knowing the half-life of those atoms, students can figure the number of half-lives since the sample solidified, and therefore the age of
Are You An Energy Efficient Consumer?
This activity engages students in learning about ways to become energy efficient consumers. Students examine how different countries and regions around the world use energy over time as reflected in night light levels. They then track their own energy use, identify ways to reduce their individual energy consumption, and explore how community choices impact the carbon footprint.
Science (Class) in Pictures: Photographing Scientific Discoveries
How do photographs help convey complex scientific concepts and ideas? How can students use and learn from scientific photography in the classroom? In this lesson, students learn about recent scientific developments by viewing The New York Times slide show “Science in Pictures.” They then become scientific photographers and create their own slide show documenting the research, discoveries and ideas they are learning about in science class.
Geologic Time: Eons, Eras, and Epochs
This resource guide from the Middle School Portal 2 project, written specifically for teachers, provides links to exemplary resources including background information, lessons, career information, and related national science education standards. This publication contains resources designed to do three things. The first is to complement teacher content knowledge and its relationship to the nature of geologic science. Geology is not a laboratory based science lending itself to traditional notions
