Source: Even during the winter, there are some wet swampy areas that defy freezing. Sometimes it’s the current; sometimes it’s the heat from decomposition that keeps the water from freezing. Alternatively chopping through ice in a shallow swampy are would also give you access to the bottom detritus. A sample was taken from my backyard pond on Dec 10th.
Sample: When taking a sample, ensure that there is plenty of vegetation. Some will still be green. You may find Duck Weed, or some kind of filamentous algae. A 500 mL sample will provide enough material for several classes. I re-purposed a used blister pack to act as well slides for this activity. When glued to popsicle sticks, my mechanical stage easily gripped this. That allowed me to have 6 samples on the stage at once.
This demo demonstrates the greenhouse effect by comparing the air temperature of a room with the air temperature inside a clear plastic bag containing black construction paper. The bag models the Earth’s atmosphere and the black construction paper models Earth’s dark surface. Continue reading →
Any Star Wars fan will recognize the remote ice planet Hoth, the location of some of the most iconic scenes from Episode V: The Empire Strikes Back, including the attack on the Rebel Alliance’s Echo Base by Imperial Walkers and Han Solo’s daring rescue of Luke Skywalker after his tauntaun was attacked by a wampa.

This rare footage has gone on record as the largest glacier calving event ever captured on film, by the 2016 Guiness Book of World Records.
On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.
Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival and a 2013 Emmy Award for Outstanding Nature Programming. It has won over 40 awards at festivals worldwide, and was also nominated for an Academy Award for Best Original Song, “Before My Time” by J. Ralph featuring Scarlett Johansson and Joshua Bell.
