Red Light, Green Light
Building upon their understanding of forces and Newton's laws of motion, students learn about the force of friction, specifically with respect to cars. They explore the friction between tires and the road to learn how it affects the movement of cars while driving. In an associated literacy activity, students explore the theme of conflict in literature, and the difference between internal and external conflict, and various types of conflicts. Stories are used to discuss methods of managing and re
Adapting to When Students Game an Intelligent Tutoring System
It has been found in recent years that many students who use intelligent tutoring systems game the system, attempting to succeed in the educational environment by exploiting properties of the system rather than by learning the material and trying to use that knowledge to answer correctly. In this paper, we introduce a system which gives a gaming student supplementary exercises focused on exactly the material the student bypassed by gaming, and which also expresses negative emotion to gaming stud
Developing Questions for Gallery Walk to Engage Higher Order Thinking
This site from SERC's Starting Point explains best practices for developing Gallery Walk questions which involves preparing questions based on a lecture's central concept, issue, or debate. A variety of questions can be used but the technique seems to work best with higher order questions relating to analysis, evaluation, and synthesis; using Bloom's Hierarchy provides a guide for wording questions at various levels of abstraction. Examples of various types of questions including comprehension,
Developing a Local Stratigraphy
In this lab activity students describe rock types in a variety of exposures to construct a regional stratigraphy. Learning goals, teaching notes and materials, equipment lists, and assessment recommendations are all provided on this website. Additionally, there are links to useful references and resources, including related field labs.

Who Can Live Here? Life in Extreme Environments
Astrobiology in the Classroom leads students in the exploration of the limits of life on Earth to extend their beliefs about life to include its possibility on other worlds. In this four-part activity, students first explore the environments of several mammals and birds to better understand how living things and their environments interact and depend on each other. In the second part, students match bacterial types with their more extreme environments. Students discover that an environment's tem
Cosmology 101
This is is a primer on scientific efforts to understand the origin, evolution, and fate of the universe. Among the questions it explores: What types of matter and energy fill the universe? What is the age and shape of the universe? How rapidly is it expanding? The website examines the Big Bang theory, as well as tests and limitations of the theory.
EPR Basics and Application to Biology
This site contains a set of powerpoint slides that discusses the basic principles underlying electron paramagnetic resonance (EPR). The slides also present examples of the application of EPR to biological systems including organic radicals in proteins, paramagnetic metal centers and spin labels.
Middle School Portal: Math and Science Pathways (MSP2)
The Cells Alive Web site (last mentioned in the October 25, 1996 Scout Report), offered by Quill Graphics, contains several activities to help students understand the basics of cellular biology. The animal cell cycle and cell mitosis animations are especially excellent visual learning tools, clearly showing what takes place during these events and giving well-written descriptions of each stage. The site also has three interactive quizzes on cell structure, cell function, microbes, and the immune
Middle School Portal: Math and Science Pathways (MSP2)
This website is a great resource for information on bridges. The site provides links to websites like PBS's Nova, where you can learn about different types of bridges and then test your knowledge by matching the right bridge to the right location (over a freeway, river, canyon or ocean waterway), or where you can read more about the forces, loads and materials that affect bridges. Another link takes you to Better Bridges, where you can find out how many bridges are in your state. Definitely a gr
The Rock Cycle: Understanding the Earth's Crust
Teachers, are you looking for new activities to excite your students about the evolution of igneous, sedimentary, and metamorphic rocks? This website, developed by the non-profit organization Math/Science Nucleus, provides numerous hands-on activities for each grade from kindergarten through sixth. The chemistry section deals with the mystery of why and how minerals and rocks are formed. The minerals segment provides students with an appreciation of the basic building blocks of rocks as well as
Middle School Portal: Math and Science Pathways (MSP2)
If you can tear your eyes away from the mesmerizing graphics on the main page, you'll find a very detailed and comprehensive cell biology tutorial created by graphic artist/biologist John Kyrk. Kyrk's animations demonstrate all major aspects of cell biology: amino acid structure, DNA replication, transcription and translation, cellular cycles (Krebs, glycolysis, mitosis), photosynthesis, and so on. The tutorial's beautiful graphics and cool animations should make studying cell biology relatively

This online challenge activity introduces a gift-counting problem that requires students to organize information in a table and then to draw conclusions. The importance of organizing information for decision making is noted for census takers, librarians, and demographers. The activity is one of 80 mathematical challenges featured on the Figure This! web site, where real-world uses of mathematics are emphasized. The solution hint suggests how to organize a useful table. Related questions ask stud
Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio
The Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio Web site is provided to "support the teaching of concepts in chemistry in freshman through graduate level courses." Dr. Thomas Chasteen's site offers links to multimedia files related to chemiluminescence, gel electrophoresis, how a grating works, gas chromatography and mass spectrometry, titrations, atomic emission detector, and much more.
