Student Exploration: Density Experiment: Slice and Dice
Define Vocabulary
Density: The degree of compactness of a substance
Mass: A coherent, typically large body of matter with no definite shape
Matter: The substance or substances of which any physical object consists or is composed
Volume: The quantity of three-dimensional space occupied by a liquid, solid, or gas
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. What do you think would happen if you threw a block of Styrofoam™ into the water? The Styrofoam will float
2. What would happen if you broke the Styrofoam up into lots of pieces, then threw the pieces into water? The pieces will still float
3. What would happen if you threw a big rock into water? The rock will sink
4. What would happen if you broke the rock into little pieces, then threw the pieces into water? The pieces will still sink
Gizmo Warm-up
The Density Experiment: Slice and Dice Gizmo™ allows you to compare different-sized pieces of the same material.
1. Check that Styrofoam is selected. Drag the whole Styrofoam piece into the water.
Does it sink or float? Float
2. Click Reset, and then click Slice to cut the styrofoam into pieces. Drag each piece into the water and then back to the block.
What happens? Each piece still floats
How do you think the amount of a material affects its tendency to sink or float?
