10 videos to watch to discuss climate change with students Shutterstock TED-Ed Innovative Educator, Kim Preshoff, based in Williamsville, NY, has been an environmental teacher for over 30 years. Here, Preshoff shares a list of TED-Ed Lessons and TED Talks to watch and discuss with students. As an environmental educator for more than 30 years, I have had the unique perspective of watching the climate change issue evolve over time and see first-hand students that care about what is happening. They care about future generations and they want change. Deep Time : A History of the Earth - Interactive Infographic Life on the planet started astonishingly early. The first living organisms, in the current model of evolution, are thought to be Prokaryotes1. The oldest known fossilised prokaryotes have been dated to approximately 3.5 billion years ago, only 1 billion years after the formation of the Earth's crust. Eukaryotes2 are more advanced organisms with complex cell structures, each of which contains a nucleus. Although incredibly hard to determine their origin, they are thought to have developed 1.6–2.1 billion years ago, although some research2 suggests eukaryotes being present even earlier than this. Around 1.1 billion years ago multicellular3 organisms are thought to have started to develop, most likely similar in form to plants such as green algae. 200 million years later true multicellularity had also evolved in animals similar in nature to today's sponges, which are organisms which can reassemble themselves.

40 Maps They Didn’t Teach You In School By the time we graduate high school, we learn that they never taught us the most interesting things in there. Sure, you might be able to name the European countries or point New York on the map, but does that give a you real understanding of how the world functions? To fill this gap, we have gathered a great and informative selection of infographical maps that they should’ve shown us at school: every single one of these maps reveals different fun and interesting facts, which can actually help you draw some pretty interesting conclusions. Show Full Text What makes infographical maps so engaging is how easy it becomes to conceive graphically presented information. The best part, there are brilliant services like Target Map that “allow everyone (from individuals to large organizations) to represent their data on maps of any country in the world and to share their knowledge with the whole Internet Community.”

40 Best Sixth Grade Science Experiments, Projects, and Activities Kids of every age love hands-on science! Teachers do, too, because the learning is a lot more meaningful when students see concepts in action. This roundup of sixth grade science experiments and activities has a little something for everyone–from biology and ecology to physics and chemistry. Bring on the science! 1.

The science of snowflakes - Maruša Bradač The phrase “no two snowflakes are alike” was first coined by Wilson "Snowflake" Bentley (1865-1931). He admired the snowflakes and wrote: "Under the microscope, I found that snowflakes were miracles of beauty; and it seemed a shame that this beauty should not be seen and appreciated by others. Every crystal was a masterpiece of design and no one design was ever repeated...When a snowflake melted, that design was forever lost. Just that much beauty was gone, without leaving any record behind.”You can explore more about his life here. The physics of how snowflakes form is very complex and some researchers devote their entire life studying these. One of them is the physicist Ken Libbrecht.
