Middle School Science Lessons

Objectives:

• Students will practice their measurement skills using a graduated cylinder to determine volume and a triple beam balance to determine mass.
• Students will determine the density of water by completing 10 trails and finding an average.

Materials:

• Student Handout (pdf) – for use with Google Sheets
• Spreadsheet for data entry (Google Sheets, view only, make a copy)
• Old Handout: Density of Water (pdf)
• Triple Beam Balances
• Graduated Cylinders: 10, 25, 50, & 100 mL
• Beaker of water

I use this lab to tie their measuring skills together and introduce the concept of density. We then do further explorations of density and practice using the formula.
