The Next Evolution of Man
This amateur video is about evolution as a gradual change to a more complex and better society. The narrator talks about "mind awareness" and "foster presence and stillness in life." This is a scholarly philosophical narration. Mr. Scott discusses the oneness of the world.
Machining Parameters: Grinding
Through this simulation, students can change the parameters of a grinding wheel and explore the effects of those changes.
Machining Parameters: Turning Process
Through this simulation, students can change the parameters of a turning wheel and explore the effects of those changes.
Predicting the Greening of Spring with Red Emperor Tulips
As the earth revolves around the sun in its annual cycle we experience seasonal change. Where will spring arrive first? What kind of patterns will we see as the wave of spring progresses? Start in the fall to think about these questions, and make some predictions. Then in the spring revisit your predictions with each Journey North news update and real-time map.
Global Climates and Seasons. A Look at Temperature and Precipitation
Several factors affect a region's climate and the number and types of seasons it experiences. Here students explore colorful animations of annual changes in temperature and precipitation.
Greenhouse Effect, Climate Change, Global Warming
The terms greenhouse effect, climate change, and global warming are often used interchangeably, yet they really refer to three separate and distinct processes. This activity examines all three and assesses whether Earth's atmosphere is getting warmer.
Phenology: The Effects of Climate Change on Ecosystem Health
The article gives a good introduction to how scientists are using plant data to study the effects of climate change.
Human Development Across the Lifespan, Fall 2007
Human Development Through the Lifespan is devoted to the study and understanding of constancy and change for human beings, male and female, in the physical, cognitive, social and emotional domains interpreted through a variety of theoretical frameworks, contexts, and interdisciplinary research.
Fertility and Family Planning
Students will gain an understanding of the change in fertility patterns in the U.S. through an examination of the change of marital status among females, childbearing trends, and how such variables are affected by race/ethnicity.
Occupational Sex Segregation and Earnings Differences
For this exercise we will: 1) examine sex segregation in employment from 1950 to 2000. 2) examine trends within three specific occupations of your choosing, and 3) for either doctors or lawyers, investigate gender and race differences on earnings and see if these differences change when we control for age.
NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.
Using data from the National Climate Data Center (NCDC) track snowfall in your area and assess snowfall levels from the Winter Olympics.
Macro to Micro Structures
This program deals with the conceptualization of micro processes and environments. It involves teaching chemistry through macro phenomena, which can be observed, and micro processes, which occur on the molecular level, and can only be imagined. Conceptual change must occur in order for students to understand chemical phenomena. Teaching for conceptual change poses a grea
Chemistry and the Environment
This program introduces the chemistry of the environment. It addresses selected topics such as water quality and purification, recycling, and the hole in the ozone layer. Bringing the students to awareness of these topics helps them understand important issues in the world around them. In studying chemistry, environmental studies or anything else, the classroom climate i
The concept of speed is introduced to the inertia-mass relationship. Concept: Force varies with mass and rate of change of speed. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.
Subtracting Mixed Numbers
Students learn to subtract mixed numbers. Instructor uses a whiteboard for demonstation. She shows students how to change the fraction so that they can solve the problem.

Toys From the Future
The Inventables guys, Zach Kaplan and Keith Schacht, demo some amazing new materials and how we might use them. Look for squishy magnets, odor-detecting ink, "dry" liquid and a very surprising 10-foot pole. Keith Schacht co-founded Inventables, a hothouse for innovation. More recently he's brought us the JobCoin listings board, the Freshwater Venture entrepreneur map, and Facebook's Grow-a-Gift. The video challenges you to look for the unexpected and to change the way you view things. This c
