Kinds of Evidence
Analyze and interpret information to construct reasonable explanations from direct observable and indirect inferred evidence.
The student uses scientific methods during laboratory and outdoor investigations.
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.
How Much Sugar is in Bubble Gum? TeachEngineering (website) - During this simple experiment—to determine whether sugarless gum loses as much mass after chewing as regular gum does—students learn the importance of experimental variables and controls; make observations; gather, analyze and interpret information, and design and conduct new experiments based on their own hypotheses. This lesson includes teacher background, assessments and extensions.

Science Discrepant Events and Critical Thinking: Suite.io (website) - Discrepant events enable students to witness scientific occurrences that have unexpected outcomes and contradict their prior knowledge. This phenomenon forces students to use critical thinking skills as they try to explain what happened.
Elaboration Lessons and Extensions
ZOOMsci: PBS Kids (website) - Choose from numerous featured investigations 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.
As part of the Signature Lesson, How Much Sugar is in Bubble Gum, have students create posters that summarize their investigations and findings. Students should work in teams to create posters and present them to the class.
