### What essential characteristic does a good experiment have?

• A.

A control group is given the experimental treatment

• B.

A single variable is tested

• C.

A control is used

• D.

Both (b) and (c)

D. Both (b) and (c)
Explanation
A good experiment should have both a control group and a single variable being tested. A control group is necessary to provide a baseline for comparison, allowing the researcher to determine the effect of the variable being tested. Additionally, using a control helps to eliminate confounding factors that could influence the results. By testing a single variable, the researcher can isolate its impact and draw valid conclusions about its effect. Therefore, both having a control and testing a single variable are essential characteristics of a good experiment.

### Why are mathematical models important?

• A.

They are especially useful in situations with many variables

• B.

They can be used to create useful digital images

• C.

They can represent how a system or process works.

• D.

All of the above

A. They are especially useful in situations with many variables
Explanation
Mathematical models are important because they allow us to understand and analyze complex situations with many variables. By using mathematical equations and formulas, we can represent and simulate how a system or process works. This helps us make predictions, optimize outcomes, and make informed decisions. Additionally, mathematical models can be used to create digital images, such as in computer graphics or simulations, enhancing our understanding and visualization of complex phenomena. Therefore, all of the above statements are true and highlight the importance of mathematical models.

### The average mass of a wolf in a pack of wolves is an example of

• A.

Mean

• B.

Distribution

• C.

Sample size

• D.

Statistical population

A. Mean
Explanation
The average mass of a wolf in a pack of wolves is an example of the mean. The mean is the average value of a set of numbers, calculated by adding up all the values and dividing by the total number of values. In this case, the average mass is calculated by adding up the masses of all the wolves in the pack and dividing by the total number of wolves.

### A model of a dinosaur is an example of a ___________________ model.

• A.

Graphical

• B.

Mathematical

• C.

Physical

C. Physical
Explanation
A model of a dinosaur is an example of a physical model because it is a three-dimensional representation of the actual dinosaur. Physical models are tangible objects that can be touched and observed, allowing for a better understanding of the real-world object or concept they represent. In this case, the dinosaur model is a physical representation of the dinosaur, providing a visual and tactile representation of its size, shape, and features.

### The chance that an earthquake will occur in your town during the next year is an example of

• A.

Correlation

• B.

Skepticism

• C.

Risk

C. Risk
Explanation
The chance that an earthquake will occur in your town during the next year is an example of risk because it represents the possibility of a negative event happening. Risk refers to the uncertainty or potential for harm or loss in a particular situation. In this case, the occurrence of an earthquake poses a potential risk to the town and its residents.

### Before you can make a decision using a decision-making model, what step must you take?

• A.

Explore the consequences of each option

• B.

Consider which values apply to the issue

• C.

Gather information

• D.

All of the above

D. All of the above
Explanation
Before making a decision using a decision-making model, it is important to gather information, consider which values apply to the issue, and explore the consequences of each option. Gathering information helps in understanding the problem and available options, considering values helps in aligning the decision with personal or organizational principles, and exploring consequences helps in evaluating the potential outcomes of each option. By taking all of these steps, one can make a well-informed decision using a decision-making model.

### If you consider what will protect our natural resources when making an environmental decision, you are examining a(n) ____________________  value.

• A.

Ethical/moral

• B.

Aesthetic

• C.

Environmental

C. Environmental
Explanation
When considering what will protect our natural resources, we are evaluating the importance of preserving and conserving the environment. This aligns with the environmental value, which emphasizes the need to protect and sustain the natural world. It involves recognizing the interconnectedness of ecosystems and the impact of human activities on the environment. By prioritizing this value, we can make decisions that promote sustainability and ensure the long-term health of our natural resources.

### Your country is considering buying land to form a nature preserve.  On this land, an endangered species of mammal is known to breed.  Which of the following is a possible  positive long-term consequence of this decision?

• A.

The population of the endangered species increases.

• B.

Habitat destruction is immediately slowed.

• C.

Environmental controls are made less strict outside the preserve area.

A. The population of the endangered species increases.
Explanation
By buying the land to form a nature preserve, the country is creating a protected area for the endangered species to breed. This decision can lead to a positive long-term consequence of increasing the population of the endangered species. The protected habitat will provide a safe and suitable environment for the species to thrive, potentially leading to successful breeding and population growth.

### In a scientific investigation, it is important that the number of objects or events being sampled be

• A.

Large enough to give an accurate estimate for the whole population

• B.

Equal to the mean number of objects or events not sampled

• C.

Equal to the total statistical population

A. Large enough to give an accurate estimate for the whole population
Explanation
In a scientific investigation, it is important that the number of objects or events being sampled be large enough to give an accurate estimate for the whole population. This is because a larger sample size provides more representative data and reduces the chances of sampling error. By having a large enough sample size, researchers can make more reliable inferences and generalize their findings to the entire population.

### A good hypothesis is more than a guess because it

• A.

Is based on intuition rather than observation

• B.

States what is likely to happen

• C.

Makes logical sense

C. Makes logical sense
Explanation
A good hypothesis is more than a guess because it makes logical sense. This means that a hypothesis is not just a random idea or intuition, but it is based on logical reasoning and evidence. A hypothesis should be able to explain the observed phenomena or predict what is likely to happen in a logical and rational manner. It should be supported by facts, data, or previous observations, which give it credibility and make it more than just a guess.
