Density and Floating Worksheets for Grade 6 Science provide focused practice with the relationship between mass, volume, density, and floating or sinking. Students begin by building essential vocabulary and then apply density ideas through comparisons, calculations, particle models, real-world examples, and scientific reasoning.

The resource moves from introductory density concepts toward more complex applications. Students identify the meanings of density, mass, volume, and material; compare objects with given mass and volume information; interpret particle diagrams showing different amounts of matter packed into the same space; and explain why one object is more or less dense than another.

What students practice

• Matching density vocabulary with accurate scientific meanings
• Comparing objects with different masses and volumes
• Using the relationship between mass and volume to reason about density
• Calculating and comparing density from given numerical information
• Ordering objects by density and checking calculation errors
• Predicting whether objects float, sink, or remain suspended
• Comparing an object's density with the density of a liquid
• Explaining examples involving ice, boats, layered liquids, and changing density
• Using tables, particle diagrams, multiple-choice questions, and written explanations

Included for classroom use

• ✔ Student density and floating practice worksheets
• ✔ Completed answer-key versions with answers clearly shown
• ✔ Mass, volume, and density tables
• ✔ Particle and object illustrations that support scientific reasoning
• ✔ Mixed practice ranging from vocabulary to application challenges

These density worksheets can be used for whole-class instruction, independent science practice, homework, review, or checking understanding before a larger assessment. The progression supports students as they move from defining density to using evidence to explain floating and sinking.

Because the tasks use specific numerical data, visual comparisons, and short written reasoning, students are asked to do more than memorize a definition. They must connect the idea of how much mass is packed into a given volume with observable outcomes. The included answer key also makes the resource practical for quick checking and review.

Use this Grade 6 physical science practice as a focused density review, a companion to lessons on mass and volume, or a classroom activity on why objects float or sink.
