Ask scientific questions
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to explore ask scientific questions.
In this lesson, we'll explore ask scientific questions. Scientific inquiry allows us to investigate and explain natural phenomena.
A hypothesis is a testable prediction that proposes a relationship between variables, often stated as an "if-then" statement: "If I increase the amount of light a plant receives, then it will grow taller." A good hypothesis must be testable (you can design an experiment to test it), falsifiable (it could potentially be proven wrong), and specific. Scientific questions ask about observable phenomena: "What effect does temperature have on reaction rate?" not "Is chemistry important?" The scientific method begins with observation, moves to a question, then a hypothesis, then experimental testing. A hypothesis is not a guess—it is an educated prediction based on prior knowledge.
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.
To examine systematically through observation and experiment
Observable facts that support or refute a claim

Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring ask scientific questions.
