This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.
In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of each material as a thermal storage material to be used as the thermal mass in a passive solar building.
Pointing at Maximum Power for PV
Student teams measure voltage and current in order to determine the power output of a photovoltaic (PV) panel. They vary the resistance in a simple circuit connected to the panel to demonstrate the effects on voltage, current, and power output. After collecting data, they calculate power for each resistance setting, creating a graph of current vs. voltage, and indentifying the maximum power point.
Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. Climate is typically described by the regional patterns of seasonal temperature and precipitation over 30 years. The averages of annual temperature, rainfall, cloud cover, and depth of frost penetration are all typical climate-related statistics. The oceans influence the worlds climate by storing solar ener
How Do Seasonal Temperature Patterns Vary Among Different Regions of the World?
The purpose of this resource is to have students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling different tilts using a three-dimensional polyhedron which they construct from paper. Students
What Is Energy? Short Demos
Three short, hands-on, in-class demos expand students’ understand of energy. First, using peanuts and heat, students see how the human body burns food to make energy. Then, students create paper snake mobiles to explore how heat energy can cause motion. Finally, students determine the effect that heat energy from the sun (or a lamp) has on temperature by placing pans of water in different locations.
Green Science: Investigating green—Creating surveys to answer questions
Being green means different things to different people. Some suggest that being green means saving energy, not wasting paper towels, going solar, harnessing wind, using less fertilizer, or buying products that are organically grown. Given that being green can mean a lot of things, what does “being green” or “going green” mean to both you and your students? To find out, we need to make informed decisions by collecting data. Therefore, the purpose of this article is to become familiar with
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
View satellite movies of air masses moving across North America
This pair of animated satellite images allows Earth science students to follow the movement of polar and tropical air masses across the United States. The introduction explains how air masses can bring clear weather or precipitation. One animation shows the movement of the polar air mass over the eastern part of the country, and the other follows the movement of the maritime tropical air mass over California. Color is used to indicate precipitation levels. Control buttons allow students to repea

Dreadful Memories: The Life of Sarah Ogan Gunning, 1910-1983
Teacher is advised to review content:
Born in the coalfields of eastern Kentucky, Gunning suffered a life of bitter poverty which became the fuel for dozens of moving songs about working people, the mines, and the great coal strikes of the twenties and thirties. Gunning's a cappella roots music is intercut throughout the interviews and archival footage.

The Biology of Aging: Why Our Bodies Grow Old
Dr. Janko Nikolich-Zugich presented the second lecture of the College of Science's Living Beyond 100 lecture series on January 31, 2012. Dr. Nikolich-Zugich is, Professor and Department Head of Immunobiology; Co-Director, Arizona Center on Aging, at the University of Arizona. Abstract: All organisms age, but we really do not have a clear explanation how and why. Do we have to grow old? Can we identify processes that can impact aging of particular parts of our bodies or, even better, of our enti
