Instructional Steps
1
Introduction
Present the Heavy Hitter Slides. Use physical gestures to show heavy (straining to lift) and light (floating like a bird). Ask students to name things that are "super heavy."
2
Hands-On Demo
Gather students around the balance scale. Show a heavy book. "When I put this on, what happens?" Emphasize that heavy things push down. Add a feather to the other side.
3
Center Rotation
Divide into two groups. Group 1 works on the independent worksheet. Group 2 uses the Balance Buddy task cards at the scale station.
4
Class Reflection
Bring the class back. Discuss: "Was the apple heavier or lighter than you thought?" Create a "Heavier vs. Lighter" anchor chart for the room.
Differentiation
Support
Provide two identical containers—one filled with sand and one empty—to make the weight difference obvious.
Challenge
Ask students to find an object that is heavier than a pencil but lighter than a book.
