Hypothesis
Why is it important to ask questions in science?
Asking questions in science is important because it helps us learn new things and find answers from experiments.
What is a prediction?
It helps us make a hypothesis based on prior knowledge.
An explanation that has been proven with the same results many times.
What are experimental groups?
The groups in an experiment that are getting tested.
How do scientists communicate their findings to others?
They write reports, talk to their pears, and show their results in pictures or presentations.
What is the purpose of an experiment in science?
The purpose of an experiment in science is to test ideas and find out if they are true or not.
What is a balance scale?

Why is Nature of Science important?
It helps us understand how science works. It teaches us how to think carefully, ask questions, and how to make smart choices.
