Scientific Method Lab Homework

You do not need to pause to record your data as you perform your experiment. You can go back and estimate the values when the experiment is complete.

False

Before you begin a scientific experiment, you should

state a hypothesis, decide on a strategy

Place the four phases of the scientific method in order.

1. Hypothesis 2.Experiment 3. Analysis 4. Report

In the pillbug experiment, how many pill bugs did you need to use to get good information for the experiment?

10

When utilizing the scientific method, there are two types of variables. They are

Dependent and Independent

After a period of time, most of the pillbugs appeared to spend most of their time on the side of the dish with sand, not cornstarch.

False

If the hypothesis in a scientific experiment is not supported, the experiment is considered a complete failure and must be repeated until a satisfactory outcome is reached.

False

In the pillbug experiment, it is important that measurements be taken twice: once at the beginning of the experiment , and once at the end of the experiment.

False

Match the action to the appropriate phase of the scientific method

Hypothesis: Formulate a hypothesis and create a strategy Experiment: Carry out the strategy, collect measurements Analysis: Draw graphs, evaluate the hypothesis Report: Document results

There are two, two-sided dishes in the pillbug experiment. In one dish, you should have placed sand in both sides. In the other dish, you should have placed _______ in one side and _______ in the other.

Sand; cornstarch

In order to come to reliable conclusions about Pillbugs preferences, you needed to use the

scientific method

When determining the scope of an experiment, you need to consider

the factor that will vary

In the pillbug experiment, an important part of the experimental strategy

Make observations at regular intervals

You should use the graph generated from your data to see if your hypothesis is supported.

True

According to the results of the pillbug experiment

pillbugs tend to prefer cornstarch over sand.
