It’s a Small World After All
How many people do you know? let's take a round number, like 100, as a good average guess. If your 100 acquaintances each know another 100 different people then you are connected by one step to 10,000 people: you are actually better connected than you thought. After n of these steps you are connected to … Continue reading the story "It’s a Small World After All"Producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains
Producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains and food webs and may compete with each other for resources in an ecosystem.
Most texts provide the basic information about producers and the different kinds of consumers (herbivores, carnivores, omnivores, and decomposers). The California Science Framework (page 61) … Continue reading the story "Producers and consumers (herbivores, carnivores, omnivores, and decomposers) are related in food chains"The role of electromagnets in the construction of electric motors, electric generators, and simple devices, such as doorbells and earphones
As noted in the California Science Framework (page 58), electromagnets may be thought of as magnets that can be turned on or off. By connecting an electric circuit, the electromagnet can be turned on resulting in the motion of some internal part of a bell, a speaker, or a motor. The internal part could be a metal, a permanent magnet, or … Continue reading the story "The role of electromagnets in the construction of electric motors, electric generators, and simple devices, such as doorbells and earphones"

When a landslide, volcano, or earthquake happens, the event can be very fast, especially compared with a slow erosion process happening over thousands of years. However, one complication to this apparently simple standard is that the underlying basis of the landslide, volcano, or earthquake is very likely to be a slow … Continue reading the story "Students know some changes in the earth are due to slow processes, such as erosion, and some changes are due to rapid processes, such as landslides, volcanoes, and earthquakes."Renewable Energy Role Models
The world's interest in renewable energy is growing, and at a time like this, some good examples of implementations of renewable energy can help further that interest. An example is the recently completed San Francisco 5 MW solar energy project, which involved the deployment of some 24,000 solar panels, making it the largest municipal solar installation in California.
This … Continue reading the story "Renewable Energy Role Models"
