Density and Material Identification Lab for High School
A one-period (50-minute) hands-on lab handout in which 10th graders calculate the density of twelve common materials, from hardwood and aluminum to Teflon and acrylic, using D = m/V. Students measure mass directly and find volume by displacement in a graduated cylinder, building measurement, data-recording, and calculation skills, with a key-ideas section that reviews density and cylinder volume.
“Create a lab handout for high school students calculating density for the following materials using D=m/V: Hardwood (Beech), Softwood (Pinaceae-Partal), Aluminum, Copper, Brass, Rubber, Nylon, Delrin (Polyoxymethylene), PVC, Glass, Lucite/Acrylic, Teflon. Students will need to calculate the volume of the materials using the displacement method and a graduated cylinder.”
Teacher Guide & Tips
- Use as a single 50-minute lab period after students have been introduced to mass, volume, and unit conversion (g and cm³); pairs or small groups work well since each group needs a balance, graduated cylinder, and water.
- Discussion question: Why does the aluminum block feel heavier than a wood block of the same size, and how does density explain that difference?
- Scaffold for struggling readers: Walk through one sample calculation (mass ÷ volume with units) together before students start, and provide a simple data table template so they know exactly where each measurement goes.
- Extension for advanced students: Ask them to predict which materials will float or sink in water based on their calculated densities, then test the prediction and explain any discrepancies, such as how voids in wood affect its effective density.
- Plan roughly 40 minutes of hands-on work for measurement and calculation, leaving the last 10 minutes for cleanup and a brief class discussion of results.
