Uni 6 Assignment One: Investigative Study Proposal and Literature Review Learning Aim: The primary objective of Uni 6 Assignment One is to equip students with the skills necessary to create a comprehensive proposal for an investigative study, along with conducting a thorough literature review. The assignment focuses on applying the theoretical knowledge gained in the course to a real-world scenario. In this specific case, the aim is to investigate the impact of a particular method (methanol usage) on the heart rate of an individual, which involves drafting a proposal, designing a method, conducting a literature review, and drawing conclusions based on comparative analysis. Assignment Overview: Proposal Creation: Students are required to develop a detailed proposal for the investigative study. The proposal should outline the rationale for the study, research questions or hypotheses, objectives, methodology, and expected outcomes. It should also include a discussion on the significance of the study and its potential applications. The proposal serves as a roadmap for the entire study and provides a clear direction for the subsequent stages. Method Design: The next step involves designing a robust method to carry out the investigative study. In this case, the focus is on using methanol to determine how it affects an individual's heart rate. The method should cover the experimental setup, variables to be measured, data collection procedures, ethical considerations, and potential challenges that might arise during the study. The method should be well-structured and scientifically sound to ensure accurate and reliable results. Literature Review: Conducting a literature review is a critical component of the assignment. Students are expected to research and identify relevant scholarly articles, research papers, and other authoritative sources that discuss similar methods involving methanol and its impact on heart rate. The literature review should critically analyze and compare the methodologies, findings, limitations, and implications of these existing studies. This step helps students contextualize their own study within the broader scientific discourse. Comparative Analysis: After reviewing multiple sources, students should compare and contrast the methodologies and findings of the chosen references with their proposed method and expected outcomes. This analysis will shed light on potential similarities, differences, strengths, and weaknesses of various approaches. The goal is to identify gaps in existing research and highlight how the proposed study contributes to the field. Conclusion: The assignment culminates with the construction of a well-structured conclusion. Based on the comparative analysis and the synthesis of information from the literature review, students should draw conclusions about the effectiveness and significance of their proposed study. This section should also discuss the potential implications of the findings and suggest avenues for future research in the field. Key Learning Objectives: Research Skills: Students will develop the ability to search for and critically evaluate relevant literature, demonstrating their understanding of research methodologies and academic standards. Proposal Writing: Crafting a comprehensive proposal requires clear communication of research objectives, methodologies, and expected outcomes. Method Design: Students will learn to design an experiment that is scientifically valid, ethically sound, and capable of yielding meaningful results. Literature Review: The assignment promotes the skill of summarizing, analyzing, and synthesizing information from various sources to build a coherent narrative. Comparative Analysis: The process of comparing and contrasting different studies sharpens critical thinking and analytical skills. Conclusion Formation: Students will learn to draw meaningful conclusions and implications from their findings, supporting their assertions with evidence. Assessment Criteria: Clarity and depth of the proposal, addressing research questions and objectives. Rigor and feasibility of the method design. Thoroughness and quality of the literature review, including proper citation and critical analysis. Thoughtful comparative analysis showcasing the ability to identify patterns and variations. Soundness of conclusions drawn from the comparison and literature synthesis. Overall, Uni 6 Assignment One is designed to provide students with a comprehensive experience in research methodology, literature review, and critical analysis, all while addressing a specific investigative study related to the impact of methanol on heart rate. This assignment prepares students for further academic pursuits and helps develop essential skills for conducting and evaluating scientific research.

, Proposal
The purpose of this experiment is to discuss and determine the effects of different
concentrations of methanol on heart rate using flea’s daphnia. A typical light microscope
makes Daphnia plainly visible at low magnification. The heart rate, which can reach 300
beats per minute, can be measured, and quantified under a variety of circumstances, such
as changing the water's temperature, or the type and quantity of chemicals added. The
strategy offers an intriguing method for examining how various compounds affect an
animal's metabolic process. Daphnia is a poikilothermic organism, which implies that the
environment's temperature has a direct impact on both its body temperature and metabolic
rate. The rate at which the heart beats change in response to changes in metabolic rate
(cardiac frequency). methanol beverages cause Daphnia's heart rate to decrease. The heart
rate of Daphnia lowers with an increase in alcohol concentration.
Hypothesis As the concentration of methanol increases, the heart rate of daphnia
decreases
Equipment
- Few daphnia - to be able to complete the experiment we need daphnia to the experiment
on.
- Microscopes slides (concavity slides are ideal) - we need microscopes slides to hold the
daphnia under the microscope.
- 3 plastic pipettes - each pipette will be used for a different concentration of alcohol on the
daphnia.
- A microscope - to exam the daphnia's heart rate
- Beaker - to place the daphnia.
- Distilled water - so the daphnia don't die.
- 1% caffeine solution
- 1% alcohol solution
- Stopwatch - to be to exam how fast or slow the heart rate of daphnia is for each alcohol
concentrations.
- Counter - to count the daphnia heart rate.
Method
15 ml of distilled water was added to a small beaker.
A micropipette was used to transfer the daphnia into the beaker. Using the pipette one drop of
distilled water was added to the microscope slide, the daphnia was then transferred to the
microscope slide. The slide with daphnia was then observed under the microscope set.The number
of heart beat that occurred within 20 seconds was counted, while I was counting, the otter partner
timed for 20 seconds on the stop watch.
Daphnia's heartbeat is quite quick, therefore mark dots in the form of the letter S on a piece of
paper to count the beats. Convert the number of dots to beats per minute to determine the heart
rate. Create a table to store the findings.
The amount of heartbeat for 20 seconds was then recorded, 1 drop of alcohol was then added to the
microscope slide using a pipette. Daphnia was observed and the number of heart beats were
counted again for 20.
