Activity 4.3: Evidence-Based Arguments for Ethanol Burning (50 min)

Target Student Performance

Students (a) use data from their investigations to develop evidence-based arguments about matter movements and matter changes when ethanol burns, and (b) identify unanswered questions about matter movement and matter change that the data are insufficient to address.

Students use evidence from their ethanol burning investigation to form arguments about what happened in the Evidence-Based Arguments Process Tool.

Setup

Print one copy of 4.3 Evidence-Based Arguments Tool for Ethanol Burning for each student. Make sure that the 4.2 Ethanol Burning Class Results 11 x 17 Poster (or spreadsheet) (1 per class) from the previous activity is available.

Directions

1. Use the instructional model to show students where they are in the course of the unit.

Assessment

During the class discussion, listen for students making connections to the investigation and their arguments. Are they drawing on observations from the investigation, or from other sources of knowledge and experience? Use the 4.3 Assessing the Evidence-Based Arguments Tool for Ethanol Burning to assess your students’ thinking at this point in the unit. At this point they have concluded their “up the triangle” inquiry journey, and are headed “down the triangle” for the application sequence.
