Density Lab

Description

Density 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.

Density Lab Stations Activity Learning Objectives
1. Calculate the density of a regular and irregular shaped object.
2. Predict if an object will float or sink in a substance with a known density.
3. Describe the factors that influence the density of a substance.
4. Compare and contrast the density of ice and liquid water.
5. Model the density of liquids with a seven-layer density column.

Science Skills Station
Students will calculate the density of regular and irregularly shaped objects. They will determine the volume and mass of the objects and use the measurements to calculate density. Then students will determine whether the objects will float or sink in three different substances: rubbing alcohol, water and corn syrup.

Narrative Station
Students will read an informational text about density. Students will also watch a video about the density of water and why solid water (ice) floats in liquid water.

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

Problem-Solving Station
Students will be provided with seven substances and their densities. Students will manipulate the substances in such a way to create a seven-layer column of liquids. The layers will remain separate and distinct.

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.
