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.
Global Climate Change : The Ross Ice Shelf
This video lecture explores the effects of climate change on the Ross Ice Shelf in Antarctica. Slides depict how a large iceberg fell off the Ross Ice Shelf in March 2000. The lecturer describes his expedition to the ice shelf shortly after this event. He describes dives conducted to observe the underwater ecosystems containing krill and jellyfish, and the ocean currents around the icebergs. Facts about the icebergs in Antarctica are presented, and the sensitivity of polar regions to climate is
Understanding Rational Numbers and Proportions
The three activities in this investigation center on situations involving rational numbers and proportions that students encounter at a bakery. These activities involve several important concepts of rational numbers and proportions, including partitioning a unit into equal parts, the quotient interpretation of fractions, the area model of fractions, determining fractional parts of a unit not cut into equal-sized pieces, and equivalence.
Quick take on Pythagoras and his theorem
A topic once reserved for high school geometry, the Pythagorean theorem is now part and parcel of the middle school curriculum. These resources offer visual demonstrations that can make the abstract theorem more concrete for students and lead them in analyzing the mathematical relationships involved, as recommended by the Principles and Standards for School Mathematics. The last resource offers background information on Pythagoras himself.
Look Alike Liquids
In this introductory activity, students will compare the way water and isopropyl alcohol appear on different surfaces. Through the activities in this investigation, students will see that liquids have characteristic properties that can be used to identify an unknown. There is a downloadable activity sheet that will be very helpful to educators, and will help students stay on track. An assessment sheet is also available on the activity page to keep track of students progress. There is also a step
In this activity, students use and create scatterplots based on information from a table, and compare and contrast annual rainfall in various places around the world.

Across Southwest Canada at Night
This video was taken by the crew of Expedition 30 on board the International Space Station. The sequence of shots was taken January 25, 2012 from 12:34:11 to 12:36:28 GMT, on a pass from near the border of British Columbia and Washington state, near Vancouver Island, to southern Alberta, near Calgary. The main focus of this video is the Aurora Borealis over Canada, which appears very near the space station during this short video.
A glimpse into the life, food, and Mardi Gras celebrations of black Creoles in French Louisiana, featuring the stories and music of "Bois Sec" Ardoin and Canray Fontenot. Dry Wood is one of a number of Les Blank's critically acclaimed films on Lousiana life and culture. Hot Pepper, a film on zydeco great Clifton Chenier, is a companion to Dry Wood.

Electric Vehicles - the race is on
Experiential, hands-on learning is the goal of the WSU Electric Vehicle Team, one of 30 clubs in the College of Engineering and Architecture. Mentored by Kirk Reinkens, students design and build one-person vehicles powered by AC electrical systems. Their skills are tested in nationally recognized Electrathons, where drivers compete to see how fast and far their cars can go in an hour.

5.4 The meaning of meaning I've spoken above as if the whole question of meaning was a simple one. I've used the word itself as if it presented no problems. This certainly isn't true. The whole issue of semantics is a matter of fierce debate among computer scientists and philosophers. What is meaning anyway? How is it possible for anything inside a computer to mean something? Exactly where does meaning return as we go back across the boundary – at the output device or in the human mind? Is the meaning of a pic

Image and Shape: Two Distinct Approaches
This paper is the result of two researches done at the district of Campeche, Florian?polis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research ?
