Using the Scientific Method
The scientific method is a process or method of research. A problem is identified, information about the problem is gathered, a hypothesis or question is formulated from the information, and the hypothesis is tested with an experiment to prove or disprove its validity.
Sounds heavy… What in the world does that mean?!? It means you don’t need to try and solve the world’s biggest science questions! The scientific method is all about studying and learning things right around you.
As children develop practices that involve creating, gathering data, evaluating, analyzing, and communicating, they can apply these critical thinking skills to any situation.
