These two density labs give 6th, 7th, and 8th grade science students practice with density concepts and density's relationship with sinking and floating. Students apply density knowledge while using the scientific method and working with others to reach a common goal. For the first experiment they will need to create an aluminum foil structure that floats when placed in water. For the second experiment they will need to create an aluminum foil structure that sinks when placed in water. These two density labs are meant to be given back to back with each other, either on the same day or over two consecutive days.

Included in this resource:

• Clear, detailed, and easy-to-follow directions
• Student recording sheets for both labs

Required materials for the density labs:

• aluminum foil
• an aquarium or large bowl filled with water
• scissors
• rulers
• one stopwatch or timer of some sort

Why you and your students will love these labs:

• The materials needed for the labs are easy to find and inexpensive.
• The teacher directions are detailed and well-thought-out, so the labs are sure to go smoothly.
• Students are highly motivated to apply what they know about density during these fun labs.
• Students follow the scientific method during the lab.
• The student sheets guide students through each lab and provide an accountability piece.
• New teacher or new to teaching science? This resource has background information and is easy to follow, even if you've never taught density or done science labs before.

This resource can also be purchased at a discount as part of the Density Package, which comes with Interactive Notebook pages, worksheets, activities, a project, and an assessment.
