Calculating Density

Calculating Density Worksheet (Grade 6 Science, TEKS 6.2C)

Give grade 6 students a real reason to do math in science. This one-page reading and activity sheet teaches mass, volume, and density with one worked example, then uses the density of water to predict whether objects sink or float.

What's Inside

• A short reading on mass, volume, and density, with the rule density = mass ÷ volume and a worked rock example
• The key idea that objects less dense than water (1 g/cm³) float and denser objects sink
• Activity 1: A data table where students find the density of a steel bolt, wood block, small rock, and ice cube, then write S or F
• Activity 2: Students number the four objects from least dense to most dense
• A visual answer key with answers marked in red

How Teachers Use It

Use it before a sink or float lab, during a unit on matter, or as practice for TEKS 6.2C. Every term is taught on the page, so no prior knowledge is needed. The sheet takes about 10 minutes and prints clearly in black and white.

This worksheet is part of the Reading in Science series for grade 6. It supports TEKS 6.2C: use mathematical calculations to assess quantitative relationships in data. Pair it with the other data analysis sheets in the series to build a short unit on working with data.

Why It Works

Each sheet teaches the key terms in plain words first, then asks students to use only what the page taught. Every calculation is laid out step by step in a table, so students build confidence while the answer key lets teachers check work fast. The clean layout is also easy to project for a whole-class review.
