Control Group- In an experiment, that which does not receive the experimental treatment

Prediction- A logical statement about what will happen in an experiment

Physical Model- A three-dimensional model you can touch

Risk- The probability of an unwanted outcome

Conceptual Model- A verbal or graphical explanation for how a system works or how it is organized

Value- Principles or standards considered to be important

Experiment- Procedure designed to test a hypothesis

Statistics- Collection and classification of data

Data- Information gathered during an experiment

Examining Correlations- When it is not possible to conduct an experiment, scientists test their predictions by doing this.

An essential feature of every good experiment is that it should- Both (a) and (b) (use a control and test a single variable)

Experimental methods include which of the following steps? - Observing, hypothesizing, predicting, experimenting, and communicating results

What is not a description of a good hypothesis? It is a guess based on previous experiments.

Imagination- is one of the key habits of mind of scientists, which allows scientists to expand the boundaries of what we know.

Graphical Model- An example is a road map

Statistics are not used by scientists to- gather data

In a scientific investigation, the size of a sample population should be large enough to- give an accurate estimate of the whole population

If you consider what will add to our understanding of the natural world in making an environmental decision you are examining a - scientific value

What is the first step in an environmental decision-making model? - Gather information

When you examine a scientific value in making an environmental decision, you- use your understanding of the natural world

Which of the following is a possible short-term consequence of creating a nature preserve?- A restriction of recreational activities on private land within the preserve by state officials

This chapter’s project included building spotted lantern fly traps. Explain how our class project followed the steps of the scientific method. For full credit, you must name each step and explain how it was followed. -

1. Question- How are the spotted lantern flies bad, and how can we get rid of them?

2. Hypothesis- We can make traps to damage the spotted lantern fly population.

3. Research- research what the flies eat, and their life cycles.

4. Observation- See which traps work best.

5. Analysis- Analyze which traps worked best, and which bait tempted the most flies.

6. Conclusion- Publish our findings, make more traps of the ones that worked best,

Provide the name and an example of two of the four types of models. -

Physical model- orreries, Graphical model- road map
