Does it float? Exploring density: Density is a property of matter that requires abstract understanding from your students. This lesson plan is a hands-on lab for exploring the concepts of mass, volume, density, and their relationship. This lab achieves several 8th grade science objectives and incorporates mathematical objectives as well. The lab can easily be used as an introductory lab for the year, thus covering not only the content objectives, but also procedures for completing labs throughout the course of the year.; Format: lesson plan (grade 8–12 English Language Arts and Science); By Trish Loudermilt.

Exploring properties of matter with submersibles: This inquiry-based learning activity allows students to explore the relationships between mass, volume, density, and buoyancy as they manipulate various materials to construct a submersible “vehicle” for deep-sea research.; Format: lesson plan (grade 8–12 Science); By Miriam Sutton.

Modeling volume: This activity helps the students see how the volume of something includes the third dimension (width or depth) which is different from area. This activity also helps the students "prove" that the volume formula actually works. Students will already know that the volume of a rectangular prism is found by multiplying the object's length, width, and height. By using the blocks as models of volume, the students should come to realize that volume can be calculated simply by multiplying the area of the base by the height of the rectangular prism. Thus, they will come to realize that there is no need to try and fill the entire box with the tiny 1cm cubes, they can simply fill the bottom (to see how many cubes are there) and figure out how many rows there will be and multiply.; Format: lesson plan (grade 6–8 Mathematics); By Erin Foerster.
