Snow Globes Lab Report

Maria’s hypothesis for this experiment is that the cold water will freeze faster, she thinks this is correct because the hot water molecules move faster than the cold water molecules, causing the hot water to take longer to freeze.

To place a reader in the mind of a character, the author must create a scenario which will appeal to the senses, and keep readers intrigued. The technique of building imagery can successfully transform the world around the reader, and connect them to the story. One Mile of Ice by Hugh Garner uses many imagery-building techniques to place readers in the mind of a man on the verge of death. In this story, Hugh Garner tells the tale of two brother-in-laws, Ralph and Pete, who venture off into town, accompanied by mare and sleigh, to get presents for the children for Christmas. However, their journey takes a very dark turn not too far into their adventure. The crisp winds become a blinding storm, in which Ralph and Pete are forced to fight for their lives. Unfortunately, only one man survives - Pete. One Mile of Ice uses visual components to build imagery, as well as tactile techniques to throw readers into the mind of the protagonist. Alongside this, the author uses auditory traits to reproduce the true terror experienced in this story by these brother-in-laws.

Conclusion: The results of this lab were found through seemingly simple equations, basing all of your work off of data such as time and distance can become frustrating due to human inaccuracy, but the results show the height and initial velocity of the marble. The results are all reasonable compared with the beginning values that we collected during the lab, and even without calculations fit into the equation. The concept of projectile motion was the basis of this lab, focusing on using kinematic variables and equations to find the

Imagine a world with no trees, no healthy grass, no glaciers, or no living creatures at all. The cause of this tragedy could be the increase in heat in the Earth’s atmosphere due to global warming. If global warming continues to increase, the world will be left empty. The Earth has been around for a long time, and many feet have walked on it, but no one has walked on this Earth without trees, grass, or creatures. With global warming, the Earth’s meteorology gets too warm, and all of the glaciers will start to melt. Global warming occurs when an increase in the carbon dioxide levels causes the temperature of the Earth’s atmosphere to rise. The Earth’s meteorology is often a subject explored in literature. For example, “Chronicles of Ice” talks

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

This science fair project will test which antacids are most potent in neutralizing lemon juice. When an acid and a base combine the base will neutralizing the acid in a chemical reaction; this is how antacids work as well. Antacids are substances that will neutralize stomach acidity which in return relieves heartburn, indigestion, or stomach pain.

Question: Will changing the water temperature affect how quickly a gummi bear dissolves in water? Hypothesis: If the temperature of the water is warmer, then the gummi bear will decrease more quickly in size than compared to cooler temperatures. Materials: Gather the following materials including: •safety equipment including: goggles, gloves, and apron •two 25 mL beakers •one graduated cylinder •one thermometer •one hot plate •8 red gummi bears from the same brand •20 mL of normal tap water in each beaker •one balance measured in grams •forceps •paper towels Procedure: 1.Gather all the materials listed above. 2.Include data tables in your experiment by doing two trials.

The objective of this project was to create a structure that will protect a raw egg and prevent it from breaking when being dropped from a minimum height of two meters. A decent hypothesis or prediction one could develop before any experimental trials would be as follows. The structure that provides the longest duration of impact between the falling egg the ground will provide the desired results of an undamaged egg. The duration of time in which the ground applies a force to the egg carrying structure is referred to as impulse. The longer the span of impact time, the more mild the force acting upon

For example if the fulcrum was to be to close too the lacch it would most likely hit the ceiling. Also, if the fulcrum was too be too far from the launch it would also hit the ceiling. The best location for distance when launching the snowball was 3 fifths of the beam away from the launch. This location made it too where the snowball gets distance and some height so that the snowball doesn't hit the ceiling and comes back down and goes really far but luck wasn't on our side for the competition. 2.Explain how the speed of the effort and the amount of effort applied changed the flight of the snowball.

Unfortunately, this experiment was not conducted in an ideal circumstance due to air resistance acting upon the marble during its flight. Air resistance acted more on the steel marble than on the plastic marble because of the different material both marbles are made of. This explains why the plastic marble traveled further than the steel marble under the same experimental setting. The air resistance acts on the opposite side of the marble’s travel which results in it slowing down the marble during flight. The plastic marble slowed down less however, which is why it was recorded to move faster than the steel marble although it was to have the same initial velocity. Overall, some of the initial hypotheses were supported, while some were not due to the circumstances the experiment was

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.

I was instructed to record a melting point range for each compound, rather than a single temperature melting point. The reason for this instruction is that polymers and unpure substance melt over a range of several degrees. Based on the melting point ranges for both substances, it is difficult to differentiate the two based on its melting point data alone. The ranges of the substances are close enough to one another that one could argue for experimental error when presenting the data as a solo identifying property.
