1.
This rubric represents how you will be scored on your understanding of lab reports and observations and inferences.
2.
In which section of the lab report do you take an educated guess of what will happen during the experiment? This section is completed before the experiment is conducted.
Correct Answer
B. Hypothesis
Explanation
In the lab report, the section where you take an educated guess of what will happen during the experiment is the hypothesis. This section is completed before the experiment is conducted as it serves as a prediction or an assumption based on prior knowledge and research. It helps to guide the experiment and provides a basis for comparison with the actual results obtained.
3.
In which section of the lab report do you mention information you already know about the problem or question? In this section you use your past experiences and observations to describe anything that will help you in making your hypothesis.
Correct Answer
D. Background Information
Explanation
In the background information section of a lab report, you mention information you already know about the problem or question. This section is where you use your past experiences and observations to provide context and describe anything that will help you in formulating your hypothesis.
4.
In which section of the lab report do you include a list of what is needed in order to conduct the experiment?
Correct Answer
B. Materials
Explanation
In the lab report, the section where you include a list of what is needed in order to conduct the experiment is the "Materials" section. This section provides a comprehensive list of all the equipment, chemicals, and other materials that were used during the experiment. It is important to include this information to ensure that the experiment can be replicated by others and to provide transparency in the research process.
5.
In which section of the lab report do you include numbered, step-by-step instructions on how to conduct the experiment?
Correct Answer
D. Method/Procedure
Explanation
The section of the lab report where you include numbered, step-by-step instructions on how to conduct the experiment is the Method/Procedure section. This section provides a detailed description of the methods and procedures followed during the experiment, including any equipment used, variables manipulated, and measurements taken. It allows others to replicate the experiment and obtain the same results. The Method/Procedure section is crucial for ensuring the experiment's reproducibility and accuracy.
6.
Graphical representations are included in a lab report.
Correct Answer
A. True
Explanation
Graphical representations are often included in lab reports to visually present data, observations, and trends. These representations can include graphs, charts, diagrams, or images that help convey information in a clear and concise manner. By including graphical representations, readers can quickly understand and interpret the data being presented, making it an important component of a lab report.
7.
Your conclusion states whether or not your hypothesis was right.
Correct Answer
A. True
Explanation
The conclusion is the statement that summarizes the results of an experiment or investigation. It is based on the evidence and data collected during the study. Therefore, it is logical to say that the conclusion determines whether or not the hypothesis was right. If the evidence supports the hypothesis, the conclusion would be that the hypothesis was correct. If the evidence does not support the hypothesis, the conclusion would be that the hypothesis was incorrect. Hence, the given answer "True" is correct.
8.
Listed below is an observation and an inference. Check the inference.
Correct Answer
B. The birds must be hungry.
Explanation
The inference that can be drawn from the observation that there are four birds on the bird feeder is that the birds must be hungry. This is because birds typically visit a bird feeder when they are in need of food. Therefore, the presence of four birds suggests that they are hungry and seeking food from the feeder.
9.
Listed below is an observations and an inferences. Check the observation.
Correct Answer
B. The plant gets 50 mL of water each day.
Explanation
The given observation states that the plant looks wilted, indicating that it may not have received enough water. The inference provided in the answer confirms this by stating that the plant gets 50 mL of water each day. This suggests that the plant's wilting could be due to other factors, such as inadequate sunlight or nutrient deficiencies, rather than a lack of water.
10.
Identify the qualitative observation.
Correct Answer
A. The desks are rectangular.
Explanation
The qualitative observation in this case is "The desks are rectangular." This is because it describes a characteristic of the desks that can be observed visually, without the need for measurements or numbers. The statement "The desks are 1.5 meters long" is a quantitative observation, as it provides a specific measurement and numerical value for the length of the desks.
11.
Identify the quantitative observation.
Correct Answer
B. The desks are 1.5 meters long.
Explanation
The quantitative observation in this question is "The desks are 1.5 meters long." This is because it provides a specific measurement (1.5 meters) which can be quantified and compared. The statement "The desks are rectangular" does not provide a specific measurement and is therefore not a quantitative observation.
