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.
Analyze and Draw Conclusions
Discovery Education, www.discoveryeducation.com
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.
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

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.
