Offered by the Science Learning Network, the Air Travelers Web site is "an introduction to the basic principles of buoyancy, properties of gases, temperature, and the technology involved in hot air ballooning." Four activities are described along with any materials needed, directions, and questions that help students understand the concepts. A bonus activity is also provided that explains how to build your own hot air balloon using common household items.
FCC History Project
The Federal Communications Commission (FCC) has initiated this history project in an effort to raise public awareness of "the extent to which every area of their life is intertwined with the communications technologies the FCC has responsibility to regulate." Aside from the commonly known FCC regulations regarding television and regulating interstate and international communications by radio, television, wire, satellite, and cable, the FCC authorization rules also protect individuals when we use
Ramp and Review
In this hands-on activity — rolling a ball down an incline and having it collide into a cup — the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.
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,
Designing Medical Devices for the Ear
Students are introduced to engineering, and more specifically, to biomedical engineering and the engineering design process through a short lecture and interactive, hands-on activity (approximately 30 minutes long), where students design their own medical device for retrieving foreign bodies from the ear canal. In this lesson, the teacher first reviews the basics of ear anatomy then discusses how ear infections occur and how they are treated. Following antibiotic treatment, the most common treat
Solar Paths: An International and Integrated Look at the Sun and Seasons
Some of the most difficult concepts for students to understand in Earth science are the ideas and explanations related to the Sun and seasons. The daily rotation of the Earth causes day and night, and the differences of how it is observed at different locations on Earth is a concept that is a challenge for many middle-school-age students to grasp. This article describes how to present these ideas to students using an international perspective and integrated approach that includes myth, archaeolo
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
"Missing Link" Dinosaur: Feather Color Determined
Scientists have determined the color of a fossilized feather ofArchaeopteryx, a birdlike dinosaur that represents an evolutionary transition between dinosaurs and today's birds.In research partially funded by the National Geographic Society and headed by Ryan Carney of Brown University, investigators used a specialized type of electron microscope to determine the pigmentation of the feather, which they say was black.

Why Study Biblical Warfare with Carly Crouch
Anyone reading the historical books of the Hebrew Bible / Old Testament can be shocked that warfare figures so prominently in the writings held by many as sacred. Dr Carly Crouch examines how warfare was understood within the religious worldview of ancient Israel.

Getting the measure of floods
The suburb of Merewether in Newcastle is providing engineers with critical data that will inform emergency personnel on how to plan better for the floods which have wreaked havoc across Australia in the past few years. A model of the suburb has been created in Sydney's Water Research Lab.
