My dog must be ill. What kind of statement is that (scientifically speaking)?
Inference, because it does not describe an observation. It is an interpretation of the behavior of the dog.

A forestry technician sees tiny holes in tree bark. He thinks that the holes were made by insects. What science skills did this technician use?
Observed with eyes the tiny holes. Inferred that the holes were made by the insects.

If someone claims that they think pea plants grow faster than corn plants, Could you investigate this through scientific inquiry? Explain.
You could, because the hypothesis can be tested.
400
What is meant by saying that a hypothesis must be testable?
An experiment must be able to support or disprove the hypothesis.

What is the difference between science and technology? How are they related?
Science is the study of the natural world. Technology changes the natural world to meet human needs. Technology usually requires the application of scientific knowledge. In turn, technology may be used by scientists in their research.

Compare and contrast the skills of inferring and predicting.
Inferring is what you do when you explain or interpret the things you observe. Predicting is what you do when you make a forecast of what will happen in the future. Predictions and inferences are closely related. One important similarity is that neither are wild guesses. Instead, both inferences and predictions are based on some sort of evidence, such as prior knowledge, past experience, or reasoning. Another characteristic shared by both inferences and predictions is that they are not always correct. There is one key difference between inferences and predictions, however. Inferences are attempts to explain observations of something that is happening in the present or has happened in the past. On the other hand, predictions are attempts to describe what will happen in the future.

Identify and describe five attitudes, or habits of mind, that are important for a successful scientist to possess.
Certain attitudes help make a scientist successful. Five important attitudes for a scientist are curiosity, honesty, open-mindedness, skepticism, and creativity. Curiosity drives scientists to learn more about the topics they study and encourages them to stick with the topics in spite of setbacks. Scientists who display honesty will always report their observations and results truthfully, which is especially important when the results go against previous ideas or predictions. Open-minded scientists are able to accept new and different ideas, but must also show skepticism, or an attitude of doubt. Often, creativity is required to invent ways to solve difficult problems or produce new things.

Identify the six major stages of the process of scientific inquiry and explain why the process is not a rigid sequence of steps.
The six major stages of the process of scientific inquiry are pose questions, form a hypothesis, design an experiment, collect and interpret data, draw conclusions, and communicate. Rather than being a rigid sequence of steps, the process of scientific inquiry has many paths. Scientific inquiry usually doesn’t end once a set of experiments is done. Often, one scientific inquiry leads to another one, which leads to new hypotheses and new experiments. Also, scientists communicate their results so that other scientists can repeat their experiment and further build on the scientific inquiry.

Suppose you want to find out the effects of light on the growth of corn. What variables would you need to control in your experiment?
If you were testing the effects of light on the growth of corn you would have to observe corn grown with different amounts of light. Light would be the manipulated variable. The growth of the plant would be the responding variable. The size of the plants to start with, the amount of water and plant food given to each plant, and the temperature would all have to be the same in order to have a controlled experiment.
