Students will be able to explore learn about the scientific method.

Today's Lesson

In this lesson, we'll explore learn about the scientific method. Scientific inquiry allows us to investigate and explain natural phenomena.

The scientific method is a step-by-step process scientists use to answer questions and solve problems. The steps are: 1) Ask a question, 2) Make a hypothesis (an educated guess), 3) Design and conduct an experiment, 4) Collect and record data, 5) Analyze the results, and 6) Draw a conclusion. This method helps us test ideas fairly and learn from evidence. Scientists around the world use these steps to make new discoveries!

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
