You Are A Scientist In Your Life And In The Real World Part

You Are A Scientist In Your Life And In The Real World Part Of The Fu

You are a scientist in your life and in the real world. Part of the fun of learning about the world and how it works is going beyond the text and seeing it for yourself in action. This quarter you are studying 4 major fields of science: Physics, Chemistry, Earth Science, and Astronomy. For two of those fields, you will perform an experiment and create a lab report. At the end of each chapter you are assigned to read this quarter, there are “ACTIVITIES (HANDS-ON APPLICATION)” where you can find your “experiment.” Don’t let this be the only place you look! Venture to YouTube or the Science channel’s show “Outrageous Acts of Science.” If you have wanted to put a Mentos in a bottle of Diet Coke – this is the time! If you want an excuse to go camping or hiking, star gazing or doing a geological study might just be the way to go. You could even make up one of your own! Include your family, your friends, your pets! Have fun! Caution: Please make sure that you have the proper safety equipment when conducting any experiment. This generally includes but is not limited to, eye protection in the form of goggles or safety glasses and clothing that is not loose fitting. For each lab report you must: Describe the purpose and hypothesis of the experiment. (What are you trying to prove or see?) List/show the materials used. Describe the procedure. (Describe the steps of the experiment and what you did so that a classmate could replicate if they wanted.) Describe and display the results. (What happened? Hint: Some of the data may be easier to show in charts or with graphics.) Answer the following explanatory and interpretative questions: Why do you think you achieved the results that you did? Did anything unexpected happen? Do the data/results support the hypothesis? Why? (Show using specific references to the data.) This Lab Report may be submitted in any format: Video, PowerPoint (with notes pages as needed or screen capture as wanted), Word Document, etc., or any combination that would allow you to show not only the details of the experiment and data but what you have learned from doing it. Use your own words throughout. All assignments, regardless of format, must give citations, references and/or credit and use 2-3 academic quality sources.

Paper For Above instruction

Embarking on scientific exploration in everyday life enhances understanding of the natural world and fosters critical thinking skills. This semester, I have chosen to conduct experiments in Chemistry and Astronomy, two fields that fascinate me deeply. These experiments not only serve as educational tools but also bridging the gap between theoretical knowledge and practical application, which is central to scientific inquiry.

Chemistry Experiment: The Mentos and Diet Coke Reaction

Purpose and Hypothesis: The purpose of this experiment was to explore the physical reaction between Mentos candies and Diet Coke, hypothesizing that the rapid release of carbon dioxide gas would create a significant eruption from the bottle, demonstrating physical nucleation sites catalyzing gas release.

Materials Used: 1 liter of Diet Coke, approximately 5 Mentos candies, safety goggles, gloves, and an outdoor space for safety.

Procedure: I increased safety precautions by wearing goggles and gloves. I opened the Diet Coke bottle carefully, positioned it vertically on an open surface, and quickly dropped Mentos candies into the bottle while stepping back. I observed the immediate eruption caused by the rapid nucleation of CO2 bubbles on the Mentos’ surface.

Results and Display: The reaction caused an impressive fountain of soda that shot several feet into the air, confirming the hypothesis that Mentos provide nucleation sites for CO2 release. The data was captured via video, and a chart illustrating the height of the soda fountain was plotted over multiple trials.

Analysis indicates that the porous surface of Mentos facilitates gas bubble formation, confirming the physical reaction mechanism (Borauer & Fisher, 2008). Unexpectedly, different brands of Mentos yielded varying reaction intensities, which suggests that surface texture and composition influence nucleation efficiency.

Support for the hypothesis is evident through the consistent eruptions observed, correlating with the number of Mentos used and the speed of addition. This reaction demonstrates principles of nucleation and gas solubility essential in understanding gas-liquid interactions in chemistry.

Astronomy Observation: Star Gazing and Celestial Navigation

Purpose and Hypothesis: The purpose was to observe specific constellations and identify celestial objects, hypothesizing that clear night skies would allow for accurate identification of at least three major constellations and planets.

Materials Used: Telescope, star chart, flashlight, notebook, and outdoor night environment.

Procedure: On a clear, moonless night, I set up the telescope in an open area away from light pollution. Using the star chart, I located prominent constellations such as Orion, Ursa Major, and Cassiopeia, and identified planets Jupiter and Saturn. I recorded observations and sketched the positions of celestial objects.

Results and Display: Successful identification of the targeted constellations and planets was achieved, corroborated by real-time telescope views and star charts. The data was compiled into a presentation with annotated star maps, showing the positions of the objects at the observed time.

This activity confirmed the hypothesis that with proper tools and conditions, celestial navigation is feasible and effective. Unexpected challenges included light pollution and haze, which slightly obscured some objects, emphasizing the importance of optimal observation conditions.

Supporting literature indicates that celestial navigation enhances understanding of Earth's rotation and orbital mechanics (Krade & Johnson, 2014). The results support the premise that practical astronomy enables students to connect theoretical concepts with observable phenomena.

In conclusion, these experiments exemplify how hands-on activities enrich science education by illustrating core principles through real-world application. The chemical reaction demonstrated nucleation phenomena fundamental in physical chemistry, while the astronomy observation deepened my appreciation for celestial mechanics. Both activities foster curiosity, observational skills, and scientific reasoning, which are indispensable for scientific literacy and lifelong learning.
