Density, float or sink, and mixtures gives Grade 6 Science students focused Physical Science practice connecting mass, volume, and density to observable properties of substances. This worksheet helps students use density to predict whether objects float or sink in water and support claims about substances in mixtures.

Build Density Reasoning

Students examine how density compares mass and volume and use measured or estimated density to predict whether an object will float or sink in water. The resource also connects density to identifying substances in a mixture, giving students practice using measurements as evidence for scientific claims.

Key vocabulary is reinforced through mass, volume, density, float, and sink. Students also explore how substances with different densities can form distinct layers when mixed, helping connect density differences to visible physical patterns.

Apply Concepts in Varied Tasks

The worksheet includes multiple-choice questions, true-or-false statements, short-answer responses, a dialogue, matching, a cloze passage, a labeled diagram, a reading passage, and an essay. These activities give students opportunities to apply density vocabulary, make float-or-sink predictions, use evidence to identify substances, and explain how density affects mixtures.

Included Teacher Materials

• Student worksheet focused on density, floating and sinking, and mixtures.
• Separate Answer Key PDF for checking student responses.
• Separate Teacher Guide PDF with learning objectives, teaching tips, discussion questions, and common mistakes.

The answer key supports efficient review, while the teacher guide provides practical support for lesson preparation, classroom discussion, and addressing common misunderstandings.

Classroom Use

Use this Grade 6 science resource for Physical Science instruction, guided practice, independent work, review, or classroom discussion. Students can apply mass, volume, and density concepts while making predictions about floating and sinking and using density evidence to reason about mixtures.

By combining vocabulary, evidence-based reasoning, visual work, reading, and written responses, the worksheet gives teachers several ways to check students' ability to apply density concepts to physical situations.
