Second, somewhat surprisingly, very little is being done right now about the effects of climate change, particularly from an investment perspective. The UN estimates that up to $300 billion per year will be required to deal with the effects of climate change in developing countries alone by 2030. It is now clear that climate change will increasingly affect the global economy – everything from PG&E to the Panama Canal, which has imposed cargo limits on certain shippers because of drought increased by climate change. Jay: When we started looking at the effects of climate change in the context of investment, we realized three things: First, climate change is already causing increased risk and impact to society and the real economy. The whole class was able to watch and sketch in great detail as students took turns dissecting fruits and interpreting the results.Q: How does climate resilience present an investment opportunity? On one occasion we used it for a botany lesson, dissecting fruit to examine it and compare the seeds. Needless to say, the camcorder has become a workhorse attached to my Lightsmith Video Platform: I use it for modeled editing, group reading from a single copy of a book, examining old photos, studying rock and mineral features, demonstrating math problems, filming tadpole development over time, etc. In a way, that seems like the whole point: Our laptops and PDAs go everywhere with us, so why not our presentation tools, too? I have to admit, neither the adapter nor my camcorder stays at school over the weekend very often. The Lightsmith package also includes a microscope adapter, and amazingly, it works not only with a microscope, but also with binoculars or a telescope. While there are more sophisticated editing programs out there, my district tech people were grateful not to have to install new software on my networked machine. The Lightsmith Video Platform also comes with short MovieMaker II and iMovie tutorials on a Resource CD, so that any teacher with Windows XP or Mac OS X can get started making movies with software he already has. The optical zoom capability of the latest camcorders is 20X, which is more than enough to match the 12X zoom of most document cameras and visual presenters. Many low-end document cameras are manual focus, which means a lot more fuss and ho-hum picture quality. It analyzes the scene and moves the lens back and forth, searching for the point where there is maximum intensity difference between adjacent pixels-that's the point of sharpest focus. The key lies in the camcorder's CCD (charge-couple device) auto-focus mechanism. It sounds so simple, but does it work? The answer is that it actually works better than a traditional (and several times more expensive) document camera. The platform also includes cable clamps, an adjustable florescent light, and a pen organizer. Just like that, you have a document camera. Simply mount the camcorder, connect it to a projector or TV with an A/V cable, and plug in the power cord. The platform utilizes a gooseneck arm with an ingenious reversible camera mount to hold a compact camcorder (sold separately) in position as a document camera. Then I ran across a product called a Lightsmith Video Platform ($199.99 and learning in my classroom has never been the same. I'D BEEN WANTING a visual presenter in my classroom for a long time and had narrowed the choice to a few of the least expensive models. An influx of presentation technology inspires a third-grade teacher to put the school camcorder to a number of innovative educational uses.įifth-grade teacher Kim Shivers discusses the function
