This document describes an experiment to demonstrate how salt can cause ice to melt faster without using an external heat source. The experiment involves placing an ice cube in each of two bowls and sprinkling salt on one of the ice cubes. The ice cube with salt will melt faster due to salt lowering the freezing point of water, meaning the ice cube only needs to be cooled to below the new freezing point rather than 0 degrees Celsius to remain solid.

To fully enjoy whisky, one should learn about its making and origins, appreciate its complex flavors, and simply try drinking it either neat or on the rocks while socializing at a bar.
Dissolve in water experiment
This document outlines an experiment to test how temperature affects the solubility of salt and sand in water. It provides hypotheses that salt will dissolve in water, and dissolve more easily in hot water, while sand will not dissolve. The experiment uses four glasses, hot and cold water, salt, sand, and a spoon. It involves adding salt and sand to the hot and cold water and observing whether they dissolve, then drawing a conclusion about how temperature affects solubility.
Salt cristals
This document describes experiments to form salt and soda crystals. For salt crystals, a solution of salt and hot water is left to evaporate in a warm place, leaving salt crystals. Salt crystals can also form around a thread of yarn suspended in a salt solution as the water evaporates. For soda crystals, a hot solution of soda and water is prepared and left to evaporate, resulting in beautiful soda crystals forming on the suspended yarn. Both experiments demonstrate how dissolving a substance in hot water and allowing evaporation causes crystals of that substance to form.

The document summarizes an experiment on instantly freezing liquid soda into soda ice. The experiment works because soda contains sugar, flavors, and carbon dioxide that lower the freezing point of the liquid. When the bottle is opened, carbon dioxide is released, raising the freezing point so that the soda freezes instantly at the temperature it was chilled to. Tapping on the bottle causes bubbles that allow ice crystals to form, proving freezing can occur without opening the bottle.
Science Experiment – 3
The experiment aimed to determine whether plain water or sugared water would evaporate faster. The experimenter poured equal amounts of water into two identical cups, adding sugar to one cup. After leaving the cups overnight, the water level in the plain water cup had decreased slightly more than in the sugared water cup. This led to the conclusion that plain water evaporates faster than sugared water, because the dissolved sugar in the sugared water absorbs water from the atmosphere and requires more energy to evaporate.

However, our group struggled to properly freeze the fudge, resulting in a sticky texture that was difficult to cut.
Erasmus head in the clouds - colapso da lata
This document summarizes a physical experiment on the effects of atmospheric pressure on an empty soda can. The experiment involves boiling water inside an empty soda can on a hot plate, then quickly inverting the can into a dish of ice water. This causes the steam inside to rapidly condense, reducing the pressure inside the can. With the outside air pressure now greater than the pressure inside, the soda can collapses inward. The conclusions are that changes in the physical state of the water and differences in air pressure inside and outside the can cause it to collapse when exposed to cold water after steaming.
Chem Lab Report (1)
The document summarizes a lab experiment on determining the solubility of an unknown salt. Students found the solubility to be 66.28g/100g H2O initially but made errors. Another student correctly obtained 49.64g/100g H2O for potassium chloride, which has an actual solubility of 34.0g/100g H2O at 20°C. Errors included insufficient salt dissolution and not properly weighing materials. The purpose of determining a salt's solubility at different temperatures was achieved but the students' results were inaccurate due to mistakes made during the experiment.

* 10 grams of water boils at 100°C
* Doubling the amount of water would not change the boiling point temperature
* So 50 grams of water would also boil at 100°C
Therefore, the temperature that would cause 50 grams of water to boil is 100°C.

Env Science - Lesson 4
Greenhouse gases are trapping heat and causing temperatures to rise. This is melting ice in Greenland and raising global sea levels. As sea levels rise, beaches could flood and stores may close. Rising seas may also cause saltwater to intrude into freshwater supplies. Physics concepts like induced currents may help monitor how much salt is mixing with fresh water over time. The small melting of ice in Greenland could ultimately have large impacts like disrupting coastal communities and contaminating drinking water.

The black piranha mitchell
The black piranha is the largest species of piranha, found in rivers in South America. It has the most powerful bite of any animal, with sharp teeth arranged in a single row that can remove flesh or crush a human hand. Piranhas are omnivores that detect blood in the water similarly to sharks. When hunting, they form schools and work together efficiently to feed on animals, birds, fish, frogs, snails, plants, and fruit. Their razor-sharp teeth are also used by local people as tools for weapons, carving, and other purposes, in addition to the piranhas being eaten as food.

Ronan super scientist t2 2018 salty ice final copy
- 1. SALTY ICE Super Scientist Presentation Term 2 2018 Created by: Ronan Kelly
- 2. WHAT IS THIS EXPERIMENT? This experiment shows how to make ice melt faster without actually using a source of blowing heat.
- 3. WHAT YOU NEED TO CONDUCT THIS EXPERIMENT You will need : • Two ice cubes • Two bowls or plates • Salt • spoon All of these ingredients can be found around the house.
- 4. METHOD You need to: 1. Place each ice cube into a separate bowl. 2. Sprinkle a spoon of salt into one of the bowls with an ice cube in it. 3. Watch the ice cube melt! Which one wins the melting race?! Would anyone like to come up and look? The one with the salt wins!
- 5. THE SCIENCE BEHIND IT This may be cool, but you need to know why it works so well. Salt makes the ice cubes melt faster. Plain water freezes at 0 degrees. Salt lowers the freezing temperature of water, so the ice cube in salt would have to be made much colder than 0 degrees to stay frozen. At room temperature this is not possible, so the ice has to melt.
- 6. QUIZ TIME 1. How many things were there to make it? And what were they? 6 2 bowls 2 ice cubes 1teaspoon salt
- 7. QUIZ 2. What was the second step? Sprinkle a tea spoon of salt into one of the bowls with an ice cube in it.
- 8. QUIZ 3. What is this experiment called? Salty Ice
- 9. FUN FACT! • In Ireland, there are trucks that go through the icy streets and sprinkle salt onto the roads. This keeps the vehicles from slipping and sliding all over the road! Now that’s clever!
