Daisy at Home Recipe for a Small Glacier Instructions 1. Crumble up the cookies and put them in the bowl. This represents dirt and rocks that will become glacial till. 2. Put two big scoops of the ice cream on top of the crumbled cookies. Glaciers begin as clean snow and ice, but they pick up dirt and rocks from the ground as they travel. So, the ice cream with its swirls represents this “dirty” glacier! 3. Slide the plastic sandwich bag over your hand. Then, slowly push down or “smoosh” the ice cream so it oozes! What do you notice? What happens to the cookie crumbles? A glacier moves in a similar way. As more snow falls on it, the added weight causes the glacier to “ooze” or “flow,” pushing the dirt in all directions. 4. To see how glaciers flow, heat up your light-colored syrup and pour it over the ice cream. This is like adding more snow to the glacier. What do you notice? Where does the ice cream go? 5. For more fun, add sprinkles, gummi bears, or other toppings! What do these additions represent on your glacier? Daisy at Home Recipe for a Small Glacier Make it a Troop Activity! Virtual Troop Meeting Ideas • Photo share. Have your Girl Scouts complete this activity on their own, and then share a photo of their completed glacier with everyone! • Text or voice discussion. Have your Girl Scouts share either one observation they made during the experiment, or one question they have about glaciers (or both!). If they asked a question, have them research the answer and share that with the troop! .

Let's Crank Some Ice Cream
Let’s Crank Some Ice Cream! The history of ice harvesting, the ice industry, refrigeration, and making ice cream Kathi Elkins 7-29-19 OLLI: Summer 2019 Ice Storage and Ice Houses: 1780 BC --- ice house in northern Mesopotamian 1100 BC --- evidence of ice pits in China By 400 BC --- Persian engineers had mastered techniques of constructing yakhchāl to store ice harvested from nearby mountains. 300 BC --- Alexander the Great (snow pits to hold snow and ice) 200s AD --- Romans (snow shops) Cold springs, root cellars Ice Houses: Yakhchāl (this one at Yazd, Iran) is a Persian ice pit or a type of evaporative cooler. Above ground, the structure had a domed shape, but had a subterranean storage space. It was often used to store ice and food. The subterranean space coupled with the thick heat-resistant construction material insulated the storage space all year. Ice Houses: Ice houses in England/UK. Ice Houses: Croome's thatched ice house, Worcestershire, UK Ice Houses: Botany Bay Icehouse, Edisto Island, SC Ice Houses: Ice house designs usually began as an underground egg-shaped cellar. This ice house, dating from 1780s and designed by architect John Nash, was discovered in 2018 buried under London streets. In 1822, following a very mild winter, William Leftwich chartered a vessel to Norway to collect 300 tons of ice harvested from crystal-clear frozen lakes. Previous imports had been lost at sea, or melted while baffled customs officials dithered over how to tax such unique cargo. John Nash designed the Royal Pavilion at Brighton, as well as Buckingham Palace.

ETH No. 25820 Gas hydrates as a functional foaming agent for viscous food matrices A dissertation submitted to attain the degree of DOCTOR OF SCIENCES of ETH ZURICH (Dr. sc. ETH Zurich) presented by Zuzana Šedivá MSc in Food Science ETH Zurich born 26th May 1987 citizen of Czech Republic accepted on the recommendation of Prof. Dr. E. J. Windhab, Examiner Dr. Martin Leser, Co-Examiner Dr. Vincent Meunier, Co-Examiner 2019 Summary A novel technology for foaming viscous slurries was designed. The process involved a crystalline gas hydrate dispersion as a functional ingredient standing in the core of the technology. Gas hydrates, also known as clathrate hydrates, are solid inclusion compounds, in which gas molecules are physically entrapped in a network of cavities made up of water molecules held together by hydrogen bonds (Marinhas et al., 2007). Gas hydrates exist at moderate pressures and low temperatures and possess a high volumetric gas storage capacity. The innovative idea of replacing highly energetically demanding foaming of viscous slurries using pure gas with the gas hydrate technology emerges in the current study. Introducing a gas as a slurry in its solid clathrate form into another viscous product stream reduces the energy input otherwise needed in powerful mixing devices.

Science Lesson Plan
How Do Glaciers Scratch And Move Rocks? Purpose: Students will model the action of a rock-filled glacier with ice cubes and learn how glaciers can make scratches in Earths surface. Text: McGraw Hill, Pg. 175 Explore Activity McGraw Hill Science Journal, Pg. 75 Resources: I have added an additional experiment that you can do in your classroom after lab to reinforce the concepts being taught this week. Learning Outcomes: Students will discuss and know how glaciers scratch and move rocks. (Homeroom Teacher) Bridge-in: Share student’s hypothesis with class: How can a block of ice help shape the Earth’s surface? Prior Knowledge: How are icebergs formed? Do you think that a glacier is able to make scratches in the Earth’s surface? If YES, then HOW? If NO, then WHY? Input from you: Review what a prediction is. What is meant by using, the word, variable(s) in an experiment? What is an observation? What do I mean when I use the term inference? (Science Facilitator) Materials: Science Notebook Science Journal Pg. 75 Paper towels Clean ice cubes Ice cubes made with sand Aluminum foil Wood scraps, large enough to scrape ice cubes against. Guided Procedure: Predict: Which ice cube do you think is more like a real glacier? Record your prediction and reasons in your journal. Using Variables: Think about how you could use the materials to test your ideas. Which ice cube will scratch a surface? Record your observations for each ice cube. Observation: Which cube will leave “rocks” behind? Place the ice cubes on a folded paper towel.

RECIPE for MAKING LIQUID NITROGEN ICE CREAM (Serves About 18-20 Students)
RECIPE FOR MAKING LIQUID NITROGEN ICE CREAM (serves about 18-20 students) NOTE: This is NOT a regular ChemDemo activity but rather a “treat” to go along with a regular ChemDemo 1. Add 1 quart Half and Half and 1 quart Heavy Whipping Cream into a large plastic or glass salad or punch bowl. 2. Add ¾ to 1 cup of granulated sugar (1 cup is a little on the sweet side). 3. 4-5 teaspoons of vanilla. 4. Optional: 1 pound of fresh fruit or preserves (not jelly). Strawberry or peach works best. If using fresh fruit, cut into small pieces. Chocolate syrup (8 oz) works well to make chocolate ice cream. If using chocolate syrup use less sugar (½ to ¾ cup). 5. Stir the mix for 2-3 minutes to dissolve the sugar. 6. Add about 2-3 liters of liquid nitrogen slowly and in small portions into the mix and stir with a wooden spoon. Pour a little at a time and stir; then continue adding small amounts of liquid nitrogen until you have the desired consistency. One person should be stirring while another gradually pours in the LN2. Another person may be necessary to hold the container when it starts getting thick. 7. Allow any excess liquid nitrogen to boil off. 8. Serve to your audience. Enough for 20 students (half a cup each). 9. Wash equipment and enjoy. SAFETY NOTE: LN2 is extremely cold (-196°C, -321°F, 77 K)!! Spilling it on you can cause serious frost- bite burns! Pouring some on unprotected skin is actually less dangerous than on clothing in contact with skin.

Ice Cream Glaciers Developed by Heather Spalding for the UH-Manoa GK-12 Program
Ice Cream Glaciers Developed by Heather Spalding for the UH-Manoa GK-12 program The awesome force of a glacier or ice sheet can carve impressive valleys, such as Yosemite Valley, and can bulldoze wide swaths of continents. The rock and soil picked up and transported by glaciers creates new landscapes as it is eventually deposited by melting and retreating glaciers. "Drift" is the generic term for all glacially deposited material. Activity Using the materials provided below, create your own glacial terrain in action using ice cream to represent your glacier. You must use at least 3 terms below in building your glacial terrain, and be able to explain and demonstrate these terms to the class in your presentation at the end of the class period. Work in groups of four, and work fast! Materials o Ice Cream Sandwiches o Vanilla ice cream o Sugar o Gumballs o Nerds candy o Chocolate cake o Oreo cookies o Tangerines o Plates Here's a short glossary of different types of glacial and ice sheet depositions: Glacial flour - rock ground to the texture of a fine powder. It usually flows out of a glacier as sediment in a glacial meltwater stream running from the glacier. Till - refers to an unconsolidated and unsorted mixture of sediment, clay, gravel, and rocks deposited by a glacier. Moraine - a French word that refers to any glacier-formed accumulation - there are a variety of moraines. Terminal moraine - an accumulation at the outermost edge of where a glacier or ice sheet existed. Recessional moraine - moraine located "behind" the outermost edge of a glacier, formed when the glacier lingers in one spot for a long time.
