Properties of Water Printable Worksheet | Grade 5 Science

This science worksheet helps students understand the properties of water, focusing on dissolved substances and solutions. By reading background information and conducting a simple investigation, learners will explore how solutes behave during evaporation and learn to separate mixtures using basic chromatography techniques.

At a Glance

• Grade: 5 · Subject: Science
• Standard: 5-PS1-1 — Understand that matter is made of particles too small to be seen.
• Skill Focus: Properties of Water & Solutions
• Format: 2 pages · 2 problems · Answer key included · PDF
• Best For: Hands-on science centers
• Time: 20–30 minutes

This resource includes a one-page student activity sheet and a complete answer key. The worksheet features a short reading passage explaining hard and soft water, followed by a real-world application question about evaporation in a fish tank. The second half provides step-by-step instructions for a hands-on chromatography investigation using common classroom materials like coffee filters and water-soluble markers.

• Guided Reading: Students begin by reading a short, accessible text explaining solutes, hard water, and soft water, establishing foundational vocabulary.
• Supported Application: Learners apply their new knowledge to explain a real-world scenario involving evaporation and mineral deposits, demonstrating comprehension.
• Independent Investigation: The activity culminates in a hands-on experiment where students observe how water separates ink mixtures, applying the concept of solutes in a practical, observable way.

This progression moves students from acquiring knowledge to conducting an independent observation.

This activity aligns with 5-PS1-1: Develop a model to describe that matter is made of particles too small to be seen. By observing how dissolved minerals are left behind after evaporation and how ink separates into different dyes, students gather evidence of invisible particles (solutes) interacting within a solution. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

Teachers can use this worksheet as an engaging introduction to a unit on mixtures and solutions. The reading and short-answer portion works well as a whole-class warm-up, while the chromatography investigation is perfect for small-group science stations. As a formative assessment tip, observe students during the investigation to ensure they can articulate why the ink separates, checking their understanding of solutes and absorption rates. Expect the entire activity to take 20 to 30 minutes.

This resource is designed for upper elementary students in grades 4 through 6. The built-in background reading provides necessary scaffolding for students who may need extra support with science vocabulary. It pairs perfectly with a broader direct instruction lesson on the states of matter, physical changes, or the water cycle.

Integrating hands-on investigations with informational text significantly improves student retention of complex scientific concepts. According to a ScienceDirect TpT Analysis, instructional materials that combine reading comprehension with practical application foster deeper cognitive engagement and better prepare students for advanced scientific inquiry. This worksheet aligns with 5-PS1-1, helping students understand that matter is made of particles too small to be seen by observing solutes, evaporation, and mixtures. By connecting theoretical knowledge about hard and soft water to a tangible chromatography experiment, educators can effectively bridge the gap between abstract concepts and observable physical phenomena in the classroom. Providing structured opportunities for students to explain their direct observations builds the critical thinking and scientific communication skills essential for upper elementary science success. This dual approach ensures learners not only memorize facts but truly comprehend the underlying mechanisms of solutions.
