Comparing Results

Comparing Results

TEKS Objective

The student is expected to compare results of investigations with what students and scientists know about the world.

Essential Understanding

The student develops abilities necessary to do scientific inquiry in classroom and outdoor investigations.

Science Background

Analyze and Draw Conclusions: Discovery Education (website) - This article provides insight on helping students to conducting science investigations, and to look for/identify patterns in the data they collect.

Data, Analysis and Interpretation: Visionlearning (website) - Detailed information on data collection, analysis, interpretation and dissemination, along with references for further reading and additional learning modules on graphing, statistics and data accuracy.

Data, Analysis and Interpretation

Signature Lesson

Delta Wing Flyer: PBS Kids (website) - Students create gliders out of paper and drinking straws, and test how different variables (addition of paper clips on different parts of the plane, use of tissue paper instead of newspaper, etc.) impact the distance their gliders fly. Students then record and explain their results, and compare their data to those submitted by other students on the website

Supporting Lessons

An Introduction to Inclined Planes: Teach Engineering (website) - Students learn how inclined planes can reduce the work necessary to complete difficult tasks. Includes teacher background, assessments and extensions.

Elaboration Lessons and Extensions

ZOOMsci: PBS Kids (website) - Choose from numerous featured experiments to engage your students in a wide range of science investigations requiring data interpretation and analysis, and the construction of explanations from observable and inferred evidence.

Assessment Ideas

Galileo’s Experiments: PBS (website) - Give each student two different sized balls or material (e.g., clay or paper) shaped into balls. Have students predict which ball will drop fastest, and then design/conduct an investigation to test their predictions. Show students the website interactive and have them compare their results to those attained by Galileo.
