Albedo Effect Lab Report

Snow globes are made of clear glass, a transparent sphere with a scenic view and a plastic toy inside the globe. The globe must be shaken to actuate the snow so the white particles can fall gradually to reach the base. When the marble (object used for this experiment) falls, it experiences two external forces which are; the gravitational force and the aerodynamic (fluid resistance) drag of the marble, which affects the rate of the marble. As the marble is falling, the speed is increased due to the gravitational force, which is pulling the marble downwards to the base of the beaker until it reaches the terminal velocity, where both external forces are equal. However, there are factors that can affect the marble’s terminal velocity, such as

melting produced a drop in pipette readings. For each gram of ice that melted, the volume change

If the temperature probes were not parallel to each other and the surface when they were being heated it could have skewed the results.

Testable Question: Does the type of material placed on ice affect the rate in which the ice melts? Purpose: When it snows in the winter time or rains and freezes, what can we use to melt away the ice, snow, and sleet faster than salt, if there is anything that melts ice faster than salt. If there is something that can melt the frozen precipitations quickly, it will benefit us. Also, melting the ice at a faster rate will lower the rate of slips and falls even faster.

To make the results of the experiment valid four variables to take into account are if the freezer is the same temperature for both tests, the water is the same water just different temperatures, the ice cube trays are the same size, and finally both trays are in the freezer for the same amount of time.

The objective of this experiment is to test the melting point of ice against different variables. I will use a control of ice against air and test this next to ice in water, sugar on ice, salt on ice and Baking Soda on ice. By measuring the melting time of each element on an ice cube I will be able to tell which element affects ice’s melting properties at what rate.

Purpose: The purpose of this experiment is to observe the temperature of ice and water during the constant addition of heat. Also, to use logger pro probes and software to collect and analyze the data. Lastly, observe graphically the temperature data as the ice melts, water warms then boils.

In this research project the question that was answered was “What makes ice melt faster?” The products used were salt, sugar, and sand. This research includes the many types of chemicals salt, sugar, and sand have. This research also includes the questions to provide more information about the research question. This question has been asked many times to see what is going to melt ice faster.

Hypothesis: If the sugar in the ice cubes will cause the ice cubes to melt quicker than the ones without it. Equipment:  1 tablespoon (20 g) White Sugar  280 ml of water (this needed to be divided in half for the different types of ice cubes, so 140 ml for each ice tray and 10 ml for each cube)  2 ice trays (with 14 cube slots)  Freezer  2 Plates  Measuring jug  Stopwatch 

In activity 17.3.2 we weighed out 150g of chilled water and 150g of pat dried ice and we put it into a styrofoam cup along with an immersion heater, and a temperature sensor. We recorded the data on LoggerPro and as the experiment is running, we continuously stirred the mixture; We ran this experiment for roughly 16 minutes; We saw that the ice was melting and once it was completely melted, the water started to get warmer and boil, we also observed steam from the water. Analyzing our data, we compared the initial mass 300g to the final mass 257.5g, there was some loss due to evaporating during the boiling process. This experiment supports the concept because we can see that when the immersion heater was melting the ice, there was a horizontal line near 0°C; When the ice was changing phase to liquid, we observed no temperature changes.

Experiment 1: Observing The Familiar For my first experiment, it was observing ice cubes put into a glass of cold water for 50 minutes. Upon reading my assignment, my first thought was how silly is this experiment and how am I going to have enough information to write at least a page over it. I was surprised at how much I observed using all my senses throughout the experiment and how interested I became in the process. After filling a glass three fourth full of cold water and putting my first ice cube in, it took approximately 7 minutes for it to completely melt.

How does the mass of ice affect the temperature of the final temperature of the iced latte? (17)

After that I waited until the entire ice cube melted. This took about two hours or so. Now that the ice had all melted and absorbed into the paper towel I could see that the ice cube had either broke through the paper towel, absorbed fully into the paper towel or leaked though in some spots. When I was finished looking over what had happened, I wrote down the results and everything all of my observations.

Ice is one of the first indicators of global warming actually occuring and it is important for research to be done on these layers of before they disappear. The recession of glaciers and the fragmentation of ice caps has been a clear sign to many that rising temperatures are having an impact, even on our very lives.
