Elk Population and Scientific Inference

The video tutorial explains how to make inferences in science by combining reasoning with evidence. It starts with a simple example of a drooping plant and progresses to a more complex five-step process for scientific inferences. The steps include understanding the question, determining and organizing evidence, interpreting the evidence, and finally making an inference with reasoning. The tutorial uses the example of the elk population in Montana to illustrate these steps.

What is an inference in the context of science?

• A conclusion drawn from combining reasoning with evidence

• A random guess based on no evidence

• A statement that does not require evidence

• A hypothesis that is always correct

In the plant example, what evidence suggests the plant needs water?

• The plant is in a pot

• The plant is a favorite

• The plant is in the sun

• The plant is drooping and the soil is dry

Why is it important to understand the question in scientific studies?

• To ensure the study is expensive

• To make sure the study is long

• To accurately address what is being investigated

• To avoid collecting any evidence

What does the term 'population' refer to in the elk study?

• A group of different species

• A single elk

• A random collection of animals

• A group of the same species living together

What is the first step in organizing evidence?

• Asking more questions

• Writing a report

• Creating a graph or chart

• Ignoring the data

How can you interpret the evidence of elk population changes?

• By focusing only on the current year

• By ignoring the data

• By looking at the increase or decrease in numbers

• By assuming the data is incorrect

What might a student infer if the elk population is increasing?

• The data is incorrect

• The elk are migrating

• There are more resources or fewer predators

• The elk are becoming extinct

What is a scientific inference based on?

• Random guesses

• Scientific laws, principles, or rules

• Personal opinions

• Unrelated data

What is the final step in making a scientific inference?

• Collecting more data

• Asking unrelated questions

• Providing reasoning for the inference

• Ignoring the evidence

Why might hunting affect the elk population?

• It makes the elk migrate

• It decreases the population

• It increases the population

• It has no effect
