Hydrophobic vs. Hydrophilic Lab

Description

Hydrophobic vs. Hydrophilic Lab Preview

SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students’ understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:
• Science Skills Station to develop science skill proficiency
• Narrative Station to build science literacy
• Assessment Station to evaluate learning and understanding
• Problem-Solving Station to foster engineering design
• Synthesis Station and Project to inspire higher-order learning

The activities at each station in this lab are detailed below.

Hydrophobic vs. Hydrophilic Stations Activity Learning Objectives
1. Discuss water as an important and common solvent.
2. Compare hydrophobic and hydrophilic substances.
3. Explain why polar substances and salts dissolve in water but nonpolar substances do not.
4. Demonstrate and evaluate the use of emulsifiers.

Science Skills Station
Students will study hydrophobic and hydrophilic substances at this station. They will determine whether common substances are hydrophobic or hydrophilic and make predictions about the chemical makeup of the substances.

Narrative Station
Students will read an informative text about water as a solvent. They will read about how we classify substances that dissolve or mix with water and others that do not. Students will also read about how polarity impacts the ability of a substance to mix or not mix with water.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to hydrophobic and hydrophilic. Students must employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will model how engineers make a hydrophobic substance mix with water. They will model the use of soap and egg yolks as emulsifiers to make water and oil mix together. Students will evaluate how these emulsifiers are used in a variety of mixtures. They will also study how engineers try to make more efficient emulsifiers.

Synthesis Station
Students will compose a CER (claim-evidence-reasoning) report to summarize the lab. Students are provided the claim statement and must support the claim with observations, data and other information gathered in the lab. Students will explain how the evidence supports the claim using scientific reasoning.

Synthesis Project
Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.

NEXT GENERATION SCIENCE STANDARDS
This laboratory does not address a specific Next Generation Science Standard, but it complements NGSS concepts. It combines the three dimensions of science learning – science and engineering practices, disciplinary core ideas and crosscutting concepts – in order to meet the standard. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.
