Basic Units: Measurement
Density Samples
PIRA Class: 1A10.70
Purpose
To explore the relationship between mass, density, & volume
Description
Students make relative tactile mass observations of different material rods.
1. Rods of identical shape, size, & color are passed
around the class.
2. Students will note the greatest difference in mass between
the wood & lead rods.
VARIATION: Float the "Floating Rock" in a bucket of water.
PEDAGOGY: Use the crystal models in discussions re. different materials compactness
Equipment
Density rods, Crystal Models
Optional: Floating Rock
