Dry ice

Popping An Ollie Physics Around Campus Ryan Meehan Physics 102 Spring 2017 This is a picture of me popping an ollie in the basement of Dooley Hall. An ollie is the first trick that many skaters learn, as it is the foundation for almost every other trick and can help skaters avoid obstacles such as small cracks and rocks that could ruin your day, and knees. The physics behind popping an ollie is very interesting, and after teaching my friends, and kids that I babysit how to skate…

experiment since I will be testing different methods of melting ice. The solution resulting from the experiment can be used throughout the world to make our roads safer. The literary reviews for this experiment are from two different sources, which both identify problems and potential solutions that relate to this experiment. Virginia’s Road Anti-Icing, Pre-Treatment, and De-Icing article addresses several treatment types, the dangers of black ice, and the different…

“Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica.” (nsidc.org). But, that is changing fast in the modern world. As the temperature of Erath has gone up in the last century. “Averaged over all land and ocean surfaces, temperatures have warmed roughly 1.33°F (0.74ºC) …” (globalclimate.ucr.edu). This has led to many wondering what the possible outcomes for the future of the planet. This is…

When it snows When it snows what comes to your mind? Maybe snow angels, maybe sledding, or hot chocolate. I love when it snows because I love winter. I like having to wear big jackets, scarfs, and boots. It usually feels like winter to me around the end of November or at the beginning of December. Snow makes me want to cozy up with a blanket in my warm pajamas and fuzzy socks and watch Christmas movies all day while drinking hot chocolate. In 2014 my family and I had a competition…

Molly and her other ice cube friends floated to the top of the cup once all of the water was in the cup, since the water was more dense than the ice cubes. Once the cup was filled the little boy brought the cup outside and set on the small play table. It was a warm sunny day, so Molly knew that at least another day had passed since she 'd been in the freezer. Molly Watched the little boy play out in the grass from her ice cube state. Since it was so warm outside the ice cubes began to melt in…

The town of Payson is a town located north of Phoenix in Arizona and sits nestled among the majestic mountains of the Mogollon Rim. The town is comprised of approximately 15, 245 people residing with approximately 6,500 homes and approximately 2,575 business (United States Census Bureau). The town of Payson is comprised of 19.47 square miles and a water area of 0.01 sq. miles. Payson is part of Gila County and operates on Mountain Time zone (GMT-7), the elevation is 4,921 feet. The two main…

twig’s broken end. When the Iroquois youth tried the same, he found the sap was sweet. Red squirrels have been observed running around from maple tree to maple tree nipping and creating deep wounds. Once the wounds have exuded some sap and it is able to dry, the squirrels return and eat freshly formed sugar…

Salt use on roads in winter salt is a common way to clear slippery roads. Salt lowers the temperature of the water which causes it to melt and it's one of the effective way of lower weather related collision. Using salt on road lower car accidents on highway up to 80%. However, salt used on roads causes rust on cars and environmental studies had showed that salt use for de-icing could affect water supplies, soil,and wildlife. Negative effect of using road salt The more salt that gets into…

by glaciers? The Laurentide ice sheet was 13 million square miles. And it shaped Canada and Minnesota. In this paper, I will explain the effects of the Laurentide ice sheet on Minnesota's landscape. Glaciers may seem irrelevant to how we live now because in Minnesota there hasn't been a glacier for a long time but, they formed our state. The last glacial advance start of the Des Moines lobe was about 75,000 years ago. The last glacial maximum which means most ice, was around 14,000 years…

Individually, snowflakes are diminutive, harmless ice crystals. However, when these seemingly innocent snowflakes cluster together in immense formations known as snow, they sustain a powerful ability to impact our world. Snowy weather has significantly affected the survival and lifestyle of nature and living things. In brief, snow poses large threats to the health, comfort, and well-being of humans, alters the process, features, and survival of plants, as well as interfere with the normal…
