Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will:

• Repeat observations to improve accuracy and know that the results of similar scientific investigations seldom turn out exactly the same because of differences in the things being investigated methods being used, or uncertainty in the observation.
• Use numerical data in describing and comparing objects, events, and measurements.
• Predict the outcome of a simple investigation and compare the result with the prediction.
• Collect data in an investigation and analyze those data to develop a logical conclusion.

Mathematics Standards
