This book was written by undergraduate students at The Ohio State University (OSU) who were enrolled in the class Introduction to Environmental Science. The chapters describe some of Earth's major environmental challenges and discuss ways that humans are using cutting-edge science and engineering to provide sustainable solutions to these problems.
In this seminar you will learn all about the importance of water and how much water we have available on Earth. You will see how different types of water are classified . You will persuade your audience to conserve water and describe different ways that they can conserve water.Standards3.2.4.A5MODELSUse models to demonstrate the physical change as water goes from liquid to ice and from liquid to vapor.

Calculating electron energy for levels n=1 to 3. Drawing a shell model diagram and an energy diagram for hydrogen, and then using the diagrams to calculate the energy required to excite an electron between different energy levels. Created by Jay.
This user's manual describes the steps for using Google Earth tours. Topics include downloading and installing Google Earth software, selecting a tour file, and playing the tour. There are also instructions on how to use some of Google Earth's additional features. A downloadable, printable version is provided.
Students learn about the physical force of linear momentum movement in a straight line by investigating collisions. They learn an equation that engineers use to describe momentum. Students also investigate the psychological phenomenon of momentum; they see how the "big mo" of the bandwagon effect contributes to the development of fads and manias, and how modern technology and mass media accelerate and intensify the effect.
Animals have traits physical and behavioral that help them survive. Some traits help animals be more successful in survival than others.
The Atlantic Coastal Plain tour is part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. This tour introduces students to glacial erratics on Long Island, the Ronkonkoma terminal moraine, and the Rock Hill erratic. Coastal erosion and deposition can be studied by viewing dunes, beaches, and wave cut banks.
This Ology website for kids focuses on Albert Einstein. It includes activities, things to make, quizzes, interviews with working scientists, and more to help kids learn about Albert Einstein.
The Early Universe provides an introduction to modern cosmology. The first part of the course deals with the classical cosmology, and later part with modern particle physics and its recent impact on cosmology.

Do you know how many calories are in a macadamia nut? This video segment highlighting a Calorimetry experiment will give you the answer.
This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in buoyancy. They will also examine the effect of salinity on density. Background information, common preconceptions, a glossary and more is included. This activity is part of the Aquarius Hands-on Laboratory Activities.
Ever wonder how a battery works? This segment highlights voltaic cells, their various components and how they operate.

Explore the structure of a solid at the molecular level. Molecules are always in motion, though molecules in a solid move slowly. All molecules are attracted to each other. Molecules can be weakly or strongly attracted to each other. The way that large molecules interact in physical, chemical and biological applications is a direct consequence of the many tiny attractions of the smaller parts.
6.896 covers mathematical foundations of parallel hardware, from computer arithmetic to physical design, focusing on algorithmic underpinnings. Topics covered include: arithmetic circuits, parallel prefix, systolic arrays, retiming, clocking methodologies, boolean logic, sorting networks, interconnection networks, hypercubic networks, P-completeness, VLSI layout theory, reconfigurable wiring, fat-trees, and area-time complexity.
This course was also taught as part of the Singapore-MIT Alliance (SMA) programme as course number SMA 5511 (Theory of Parallel Hardware).
