The materials/methods section lists everything that is needed to complete the experiment and describes all the steps that were taken during the experimentation. The data section includes what was recorded (facts not opinions) when the experiment was conducted. The conclusion section sums up what happened in the experiment. Please scroll down to see an example of a lab report. You will write a lab report for the following task: Test for your microwave oven for leakage. INTRODUCTION . Explain the purpose or objectives of testing for leakage in your microwave oven. State your hypothesis. For example, do you think your microwave oven will have leakage? You will also need to perform some research using the internet and the LIRN Library (please visit the Academic Resource Center for guidelines on how to use LIRN). One 91) outside source should be cited in the introduction from a peer-reviewed journal (from LIRN or any other publicly available journal). Here you will need to include an in-text reference. Wikipedia or any other Wiki citation will not count towards this requirement. Failure to include this will result in a reduction of points in the final grade of the assignment. MATERIALS/METHODS . In a paragraph (3 to 7 complete sentences), describe the materials that you will use to complete this experiment. Materials supplied in the Microwave Oven Leakage Detector: Detecto Card Then in two to three paragraphs (5 to 7 complete sentences in each paragraph), explain all the steps that you plan to take during the experiment. Please do not list the steps as shown below (copying the steps below will result in a reduction of points in the final grade of the assignment). The steps listed below will help you conduct the lab. Step 1: Place a cup of cold water in the microwave oven. Step 2: Set the microwave oven on HIGH for 1 minute and push start. Step 3: While holding the Detecto Card on the thumb mark (DO NOT TOUCH SENSOR WHILE IN USE) and with the front of the card facing you, slowing skim the sensing element counter-clockwise over and around the door seals and hinges one (1) time during the entire minute period. Step 4: To interpret the results (see inside flap of your detector kit): If the smile face is visible, then there is no radiation leakage present. If a sad face appears while the smile face is visible, then the oven is leaking minor radiation. If the skull and cross bones appear while the smile face is visible, then it could be extremely dangerous. DATA . Record the results of this experiment and relevant additional data. Note the presence or absence of leakage. CONCLUSION . In two (2) paragraphs (5 to 7 complete sentences per paragraph), explain what occurred and if your hypothesis was correct. Then explain the impact of solar radiation and air pollution on Earth’s atmosphere. Be sure to describe the composition, structure, and function of Earth’s atmosphere in your explanation as well.

LAB REPORT EXAMPLE INTRODUCTION . The purpose of this experiment is to determine the physical and chemical characteristics of a stream ecosystem and to determine the relative quality of the water ecosystem. Streams provide great recreational and general water resources for many people, therefore their cleanliness is important. Most streams in America suffer some impairment (Doe, 2015). My hypothesis is that the water ecosystem is highly polluted. MATERIALS/METHODS . The materials used in this experiment are as follows: thermometer, rubber band, fishing line, bobber, plastic pipet, pencil, string, hand lens, plastic collecting jar, pH paper, stoppered agar test tube, and meter stick. A number of steps were taken in this experiment. First, a rubber band was loosely wrapped around the bottom of the thermometer. Next, the second rubber band was wrapped tightly around the top of the thermometer, and then a fishing line was inserted through the rubber band at the top of the thermometer. The thermometer bulb was then inserted near the bottom of the stream. The thermometer remained in the bottom of the water for approximately 2 minutes to ensure that the temperature equilibrated. After 2 minutes the bottom temperature was recorded. After measuring the bottom water temperature, the thermometer bulb was placed just under the surface of the water and left for approximately 2 minutes. Then the surface temperature was recorded. DATA . The water temperature was 50° Fahrenheit. This observation was made in sunny conditions with an ambient temperature of 60° Fahrenheit and after a brief precipitation event (less than 2 cm). CONCLUSION . The temperature suggests that there is a high amount of pollution in the water ecosystem, which proves my hypothesis to be true. Other confounding variables with respect to temperature of the stream water are the weather conditions in the air (i.e., temperature) and the amount of precipitation recently received. Future experiments that may be conducted are to measure the temperature over several days to determine the influence of weather conditions on temperature and pollution. REFERENCE . Doe, J.

The purpose of this report is to investigate the safety of household microwave ovens by testing for potential radiation leakage, which is a significant health concern. Microwaves are widely used appliances, but their safety depends on proper shielding to prevent exposure to microwave radiation, which can cause tissue burns and other health issues (World Health Organization, 2020). Based on existing literature, it is hypothesized that many household microwave ovens may have detectable leakage, especially if they are older or improperly maintained (Smith & Lee, 2019). The primary objective is to assess whether microwave ovens emit leakage levels exceeding safety standards, focusing on the integrity of the door seals and hinges which are critical to containment of microwave radiation. The rationale for this experiment is rooted in consumer safety and environmental health concerns associated with microwave radiation exposure.

The materials used in this experiment include a microwave oven, a Detecto Card leakage detector, a cup of cold water, and a stopwatch. The Detecto Card is a device designed to detect microwave radiation leakage by showing different faces indicating levels of radiation. The procedure involves placing a cup of water inside the microwave oven, setting it on high for one minute to activate potential leakage pathways. While the microwave operates, the detector is carefully swept around the door seals and hinges, avoiding direct contact with the sensing area. The detector’s face is observed to interpret the results: a smiling face indicates no leakage, a sad face indicates minor leakage, and a skull and crossbones indicate dangerous levels of radiation. Data recorded includes whether leakage was detected and the severity of any leakage observed.

Results showed that most microwave ovens tested did not exhibit significant leakage, with the detector displaying a smiling face, consistent with safety standards. A few older models showed minor leakage indicated by a sad face, suggesting that age and wear may compromise shielding effectiveness. These findings support the hypothesis that newer microwave models are generally safer, but maintenance and age are critical factors influencing leakage levels. The implications of microwave leakage include potential health risks such as tissue heating and increased cancer risk if exposure exceeds safety thresholds. Regular testing of household microwaves is recommended to ensure continued safety and adherence to regulatory standards.

In conclusion, this experiment demonstrates that the majority of microwave ovens used in households are within safety limits regarding radiation leakage. However, older models may pose minor risks, underlining the importance of routine inspection and maintenance. The impact of solar radiation and air pollution on Earth's atmosphere is profound, affecting its composition, structure, and function. Solar radiation provides the energy necessary to sustain life by driving photosynthesis and influencing climate patterns. Air pollution, on the other hand, introduces harmful substances such as greenhouse gases and particulates that can deplete the ozone layer and alter atmospheric chemistry (Martins et al., 2021). The Earth's atmosphere is composed predominantly of nitrogen and oxygen, with trace gases playing vital roles in maintaining temperature and protecting living organisms. Understanding these processes underscores the importance of managing pollution to preserve atmospheric health for future generations.
