An Introduction to the Coordinate Plane
This math site has students find points on a number line and graph points in the coordinate plane. Site includes information about negative numbers on a line, changing the scale of a graph, estimating points, and tricky graphs. A glossary of terms, links to other sites, and suggestions on how to use the material can also be found.
What happens to the density of a balloon as it is heated and cooled? This material is part of a series of hands-on science activities designed to arouse student interest. Here students use a hair dryer to heat a helium-filled Mylar balloon, causing it to rise, and let it cool, causing it to drop. The activity includes a description, a list of science process skills and complex reasoning strategies being used, and a compilation of applicable K-12 national science education standards. Also provide
Enough to Go Around : Edible Vaccines
A great feature from the Why Files, this Web site introduces the research of plant biologist Charles Arntzen of Arizona State University, a pioneer in the development of edible vaccines. Written in entertaining and readable Why Files style, this easy-to-navigate Web site explains how edible vaccines are made, how they work, how they may significantly increase vaccination rates in developing countries, and so on. Relevant links to archived Why Files stories and other sources are provided.
Ohio resource center for mathematics, science, and reading
ORC provides links to peer-reviewed instructional resources that have been identified by a panel of Ohio educators as exemplifying best or promising practice. Available resources also include content and professional resources as well as assessment and general education resources that will support the work of preK to 12 classroom teachers and higher education faculty members. The resources are correlated with Ohio's academic content standards and with applicable national content standards.
Measurement is best learned through direct applications or as part of other mathematical topics. A measurable attribute of an object is a characteristic that is most readily quantified and compared. Many attributes, such as length, perimeter, area, volume, and angle measure, come from the geometric realm. Other attributes are physical, such as temperature and mass. Still other attributes, such as density, are not readily measurable by direct means.
The life sciences investigate the diversity, complexity, and interconnectedness of life on earth. Students are naturally drawn to examine living things, and as they progress through the grade levels, they become capable of understanding the theories and models that scientists use to explain observations of nature.

The China Model: Appeals and limitations of state capitalism
For some people, China's impressive rebound from the recent financial recession proves that a China model has emerged and will work better for China and some other developing countries than the Western model of modernisation. Zhao argues that while... (Running Time 72:01)
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
Designing a Medical Device to Extract Foreign Bodies from the Ear
Students learn the engineering design process by actually utilizing the steps, from identification of the problem to designing a device and evaluating its efficacy and areas for improvement. A quick story at the beginning of the activity reveals the problem: a small child put a pebble in his ear and we don’t know how to get it out! As biomedical engineers, the students are asked to design a device to remove it. Each student pair is provided with a model ear canal and a wide variety of classroo
Design Step 2: Research the Problem
Through Internet research, patent research, standards and codes research, user interviews (if possible) and other techniques (idea web, reverse engineering), students further develop the context for their design challenge. In subsequent activities, the design teams use this body of knowledge about the problem to generate product design ideas. (Note: Conduct this activity in the context of a design project that students are working on, which could be a challenge determined by the teacher, brainst
How Far Does a Lava Flow Go?
While learning about volcanoes, magma and lava flows, students learn about the properties of liquid movement, coming to understand viscosity and other factors that increase and decrease liquid flow. They also learn about lava composition and its risk to human settlements.
Building an Electromagnet
Student teams investigate the properties of electromagnets. They create their own small electromagnet and experiment with ways to change its strength to pick up more paper clips. Students learn about ways that engineers use electromagnets in everyday applications.
Solid, Liquid or Gas?
Students are given a variety of materials and asked to identify if each material as a solid, liquid or gas. They use their five senses — sight, sound, smell, texture and taste — to identify the other characteristics of each item.
In this activity, students will design a process that removes the most iron from the cereal. This activity is meant for the students to experiment with different materials using what they know about iron, magnets, and forces to design the best process for removing the iron from the cereal.
Students will discover the scientific basis for the use of inclined planes. They will explore, using a spring scale, a bag of rocks and an inclined plane, how dragging objects up a slope is easier than lifting them straight up into the air. Also, students are introduced to the scientific method and basic principles of experimentation. Finally, students design their own use for an inclined plane.
Too Much Pressure!
In this activity, students learn how engineers design faucets. Students will learn about water pressure by building a simple system to model faucets and test the relationship between pressure, area and force. This is a great outdoor activity on a warm day.
Engineer a Sneaker
The goal is for students to understand the basics of engineering that go into the design of a sneaker. The bottom or sole of a sneaker provides support, cushioning, and traction. In addition the sole is flexible and can have some fashion based functions such as cool colors and added height. The sneaker is a well-engineered product, utilizing a variety of materials to create a highly functional, useful shoe. This unit focuses on having the students select specific design requirements, such as goo
Building a Fancy Spectrograph
Students create and decorate their own spectrographs using simple materials and holographic diffraction gratings. A holographic diffraction grating acts like a prism, showing the visual components of light. After building the spectrographs, students observe the spectra of different light sources as homework.
