Plants Activity 3.1 Overview

Target Student Performance

Students develop hypotheses about how matter moves and changes and how energy changes when radishes move and grow and make predictions about how they can use their investigation tools—digital balances and BTB—to detect movements and changes in matter.

This lesson helps students prepare for the Plants Investigations (Activities 3.2-3.4). An optional aid for this lesson is to have a ‘demo’ investigation setup to show students what they will be doing in the next lesson. If you chose to do this, see the materials list in Activities 3.2 and 3.3. Another optional extension to this lesson is for students to plan their own investigations. If you choose to do this, you may or may not want to have extras of the materials on hand in case groups of students want a closer look at their available materials. Optionally, print a few copies of the BTB Color Handout for students to use as a color reference.

Refer to the BTB Information and Instructions Handout for information about preparing BTB.

Print one copy per student of the 3.1 Predictions and Planning Tool for Plant Investigations. Prepare your computer, projector, and speakers for the Carbon TIME Growing Plants Video and the 3.1 Predictions and Planning about Radish Plants Growing PPT. Print one copy of the Three Questions 11x17 Poster and display it on your classroom wall. Print one copy of the Three Questions Handout for each student. Retrieve the materials from Activity 1.2. This may include a PPT slide from the lesson in which you typed students’ responses or a photograph of their sticky notes as well as the students’ completed 1.2 Expressing Ideas and Questions Tool for Plants Growing.
