Resources Provided

Setup

Print one copy of 5.2 Evidence-Based Arguments Tool for Mass Changes for each student. Make sure that the 3.2 Plants in the Light and Dark Class Results 11 x 17 Poster and 5.1GL Observing Plants’ Mass Changes Class Results 11 x 17 Poster from previous activities are available. Set up computer, speakers, and projector for students to view the Carbon TIME Growing Plants Video.

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 55.2 Assessing the Evidence-Based Arguments Tool for Mass Changes to assess your students’ thinking at this point in the unit. At this point, they have concluded their “up the triangle” journey, and in the next activities they will head “down the triangle” for the application sequence.

Tips

Have the students store their 5.2 Evidence-Based Arguments Tool for Mass Changes in the same place as their Expressing Ideas and Predictions Tools so they can be easily revisited.
