Example Lab Report and structure Monash Uni ------------------------------------------------- The lab report The laboratory report is an important form of writing for scientists as it provides a record of experiments completed. Depending on the type of task or investigation you carry out‚ the sections of the written piece may vary‚ but a lab report or project report will usually have a title page‚ abstract‚ introduction and methods‚ results‚ discussion sections‚ a conclusion and references test

The dependent variable is the Brassica Rapa and it is depending on the temperature. Before the experiment took place‚ all plants were in 22 degrees Celsius for three weeks to grow to the preferred maturity. They were then taken out and pollinated. After pollination the plants were set in separate temperatures to mature for another two weeks. After the two weeks were over‚ the plants were taken out of their temperatures and soil to determine maturity and productivity. To do so‚ the plants were

that can see and distinguish temperature are called‚ “thermal imagers.” These imagers convert the perceived radiation into scaled colors relative to its temperature and create a different color per area. The basis to how these camera can see this radiation is that objects have blackbody radiation (Seffrin). Objects that can absorb light would also emit radiation (Rossing‚ 129). The emittance makes it identifiable to the camera and scalable to the real current temperature. These imagers have been used

amylase at sixty degrees. At temperatures other than optimal for both observations concluded less progression to the visual change (Venturi‚ 2009). Amylase in a mixture of starch produced different color variations when stimulated with its independent variable of temperature showing its effectiveness. The dependent variable was the visual change of color from variations of black to yellow. According to our experiment data all enzymes do not establish one optimal temperature in which they can catalyze

another as a result of temperature difference. • Thermodynamics is concerned with the amount of heat transfer as a system undergoes a process from one equilibrium state to another. • Heat Transfer deals with the determination of the rates of such energy transfers as well as variation of temperature. • The transfer of energy as heat is always from the highertemperature medium to the lower-temperature one. • Heat transfer stops when the two mediums reach the same temperature. • Heat can be transferred

Problem or Question State the research problem or question in one sentence. The problem should be very specific and measurable. Write one sentence in the form of a question or problem statement. Problem Statement: How do different ambient temperatures affect the rate of body cooling? 2. Predict a solution to the problem or an answer to the question. This will be in the form of a hypothesis. This solution design or hypothesis should be based on previously obtained knowledge or research

matter: ice as the solid‚ water as the liquid‚ and steam as the gas. We know that we can quickly change between the different forms of H2O by either increasing or decreasing temperature. We have worked with hot plates and thermometers in other labs before‚ so we know how to be safe. I wonder what a graph of the changing temperatures over time between the phases would look like. Hypothesis Based on prior learning‚ I predict that the graph of the water phase changes will not be one straight slope

1. Assume that you have 100 years of continuous temperature records from your local weather service office. Discuss some of the difficulties you might have trying to determine whether average temperatures have increased during this period. 2. What are meant by the terms positive and negative feedback mechanisms? Give an example of a process that would be considered a positive feedback mechanism during a period of warming on the earth. Can you think of a negative feedback mechanism? 3. Discuss
