Introduction

What Is the Scientific Method?

The scientific method is a process that scientists use to investigate and understand our world. You can use this method every day. In fact, you’ve probably used it before.

Here is how the process works: First, look around and observe something. Next, ask yourself some questions about your observation. Gather information about what you observed. Then use that information to form a hypothesis—one possible explanation. Now you can make some predictions based on your hypothesis.

But that’s just the beginning. You must test your hypothesis. Make a prediction based on your hypothesis and gather data to test it out. Was your prediction right or wrong? If it was wrong, then you have gained new data. This is excellent! Use your new data to change your hypothesis, then test it again.

Remember, do not try to prove your hypothesis. To do good science, try as hard as you can to disprove your hypothesis. Get someone to help you try to disprove it. Keep testing and modifying your hypothesis until you are able to consistently predict the outcome of your experiment.

Now, at last, you can use what you’ve learned to develop a working theory. You have increased your understanding of how the world works and you may have generated new scientific knowledge to share.

The Scientific Method is an ongoing process—it keeps going and going. As we learn more about our world, our hypothesis, theories, and scientific laws can change based on new evidence.

A Note on Next Generation Science Standards

This collection of experiments is aligned with the Next Generation Science Standards, or NGSS. NGSS were developed by educators and scientists across the United States to improve science education for K-12 students. Each experiment in this guide identifies the standard(s) it is designed to meet.

Stand Back, We’re Going to Do Science!

When doing the experiments in this book, use the scientific method to observe, question, hypothesize, test, gather evidence, and learn. Enjoy the process!

What You Will Learn

Have you ever wondered how animals and plants survive in a changing environment? Organisms can deal with a certain amount of change (for example, hotter or colder than normal temperatures), but if there is too much change too quickly, the organism might not be able to keep up.

In this activity, you will pretend you are an animal foraging for food and see if you are able to survive in a changing
