Physical Science Unit 1 Test - Scientific Investigation Quiz

The correct answer is L x W x H because to find the volume of a box, you need to multiply the length (L), width (W), and height (H) of the box. This formula calculates the amount of space inside the box, which is necessary for determining the size and quantity of items that can be shipped or stored in it.

The correct answer is dependent, independent, and control. In experimental design, these are the three types of variables that are commonly used. The dependent variable is the outcome or response that is being measured or observed in the experiment. The independent variable is the variable that is manipulated or changed by the researcher to see its effect on the dependent variable. The control variable is a variable that is kept constant or unchanged throughout the experiment to ensure that any observed effects are due to the independent variable and not any other factors.

The volume of the marble in the graduated cylinder is 10 cm3. This can be deduced from the fact that when the marble is added to the graduated cylinder containing 80 mL of water, the water level rises to 90 mL. Since the volume of the water increased by 10 mL, it indicates that the volume of the marble is also 10 mL or 10 cm3.

The prefix "milli-" in the question refers to a unit of measurement that is equal to one thousandth (0.001) of the base unit. In this case, it means that the prefix "milli-" represents a value that is smaller than the base unit by a factor of 0.001.

A quantitative observation refers to the measurement or analysis of numerical data. In the given options, "numbers" is the only choice that represents numerical data. The other options, such as "zoo animals" and "names," do not pertain to quantitative observations as they do not involve numerical values. Therefore, "numbers" is the correct answer as it aligns with the definition of quantitative observation.

A graduated cylinder is used to measure the volume of an irregularly-shaped solid because it has precise markings that allow for accurate measurement of liquid volume. By placing the irregularly-shaped solid in the graduated cylinder and measuring the change in liquid volume, the volume of the solid can be determined. A ruler is not suitable for measuring the volume of an irregularly-shaped solid as it is designed for measuring length. A balance is used to measure mass, not volume. A thermometer is used to measure temperature, not volume.

To describe the length of a grain of rice, millimeters (mm) would be the most appropriate unit of measurement. Millimeters are used to measure small objects or lengths, and a grain of rice is a very small object. Decimeters (dm), meters (m), and kilometers (km) are all larger units of measurement and would not accurately describe the length of a grain of rice.

Physical Science is indeed the study of the relationship between matter and energy. It involves examining the properties of matter and how it interacts with energy in various forms such as heat, light, and electricity. This field of science explores the fundamental principles and laws that govern the behavior of matter and energy, providing a deeper understanding of the physical world around us.

Mass and weight are not the same thing. Mass refers to the amount of matter in an object and is measured in kilograms, while weight is the force exerted on an object due to gravity and is measured in newtons. The weight of an object can vary depending on the strength of gravity, but its mass remains constant. Therefore, the statement that mass and weight are the same thing is false.

The statement "Sheila has a stain on her shirt" is an example of a qualitative observation because it describes a characteristic or quality of Sheila's shirt, specifically the presence of a stain. Qualitative observations do not involve numerical measurements or values, but rather focus on describing the attributes or qualities of an object or event. In this case, the observation is based on visual inspection and does not involve any quantitative measurements or predictions.

The correct answer is "All of the above" because when communicating experiment results in science, it is important to use tables and graphs if needed to present data in a clear and organized manner. Additionally, a conclusion should be included to state whether the hypothesis was right or wrong, providing a summary of the findings. Lastly, it is crucial to ensure that the lab report is free from bias, as this ensures the objectivity and accuracy of the results.

To understand scientific investigation, one needs to have basic science skills and knowledge. This includes a strong foundation in scientific concepts, theories, and principles. Additionally, understanding and applying the scientific method is crucial in conducting scientific investigations. The scientific method involves making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions. Science Boot Camp may not be necessary to understand scientific investigation as it is not a recognized method or skill in this context.

The correct answer is "density = mass / volume". This formula is used to calculate the density of an object or substance. Density is defined as the mass of an object divided by its volume. By dividing the mass by the volume, we can determine how much mass is present in a given volume of the substance. This formula is commonly used in physics and chemistry to understand the physical properties of materials.

Observation is the correct answer because it refers to the act of using our 5 senses (sight, hearing, touch, taste, and smell) to gather information about the world around us. Observations are based on direct evidence and are considered to be factual and objective. Inferences, predictions, and hypotheses involve making assumptions or educated guesses based on observations or other information, but they are not the same as the act of observing itself.

The given statement is false. Physical science is not the study of two fields of science called Biology and Physics. Physical science is actually a branch of science that deals with the study of non-living systems and natural phenomena, including physics and chemistry. Biology, on the other hand, is the branch of science that deals with the study of living organisms. Therefore, the correct answer is false.

The given statement is true. The phrase "King Henry Doesn't Usually Drink Chocolate Milk" is a mnemonic device used to remember the six most common SI units for measurement. Each word in the phrase represents the first letter of a unit: kilogram, hectogram, decagram, unit (meter, liter, or gram), decimeter, centimeter, and millimeter. By using this phrase, it becomes easier to recall and remember these units when needed.

Scientists usually state an hypothesis in an "If...then..." format.

The metric prefix "kilo" means "thousand." It is commonly used to denote a factor of 1000 in measurements. For example, kilogram is a unit of mass that is equal to 1000 grams, and kilometer is a unit of length that is equal to 1000 meters. Therefore, "kilo" is the correct answer to the question.

The correct answer is 354.46g. This is the mass of the rock in the picture.

The correct answer is 1,000 cm because there are 100 centimeters in 1 meter, so multiplying 10 meters by 100 gives us 1,000 centimeters.

Charts, graphs, and scientific notation are all different ways to collect data and organize information in a useful way. Charts and graphs visually represent data, making it easier to understand patterns and trends. Scientific notation is a way to express very large or very small numbers in a compact and standardized format. These methods help to present data in a clear and organized manner, making it easier to analyze and draw conclusions. "Ship it off to another lab" and "leave it in your backpack" are not valid ways to collect and organize data as they do not involve any systematic approach or organization.

Inference is the correct answer because it refers to the process of reaching a conclusion based on the information provided. It involves using reasoning and logical thinking to make an educated guess or interpretation about something that is not explicitly stated. Inference is an important skill in critical thinking and helps to draw conclusions and make predictions based on available evidence.

In order for a hypothesis to be valid, it must be testable. This means that it must be possible to design and conduct experiments or gather evidence that can either support or refute the hypothesis. Without the ability to test a hypothesis, it cannot be proven or disproven, and therefore cannot be considered valid.

Scientific Laws tell us what happened. Scientific laws are principles or rules that describe the behavior or patterns observed in nature. They are based on extensive research and experimentation and provide explanations for phenomena or events. By studying scientific laws, we can understand and predict what has occurred in the natural world. These laws are formulated through careful observation, data analysis, and repeated testing, making them reliable and trustworthy sources of information about the "what" in scientific phenomena.

A bar graph is the best choice to measure a large rate of change over time because it clearly displays the magnitude of the change in a visual and easy-to-understand format. The height of the bars represents the quantity being measured, allowing for quick comparison and identification of the largest changes. Additionally, the distinct bars make it easier to track the changes over time and identify any patterns or trends that may be present.
