This zip file contains materials for middle school science lessons on density, buoyancy, and how boats float as part of a unit on the properties of matter. The unit was designed for 6th graders in NYC.

Includes:
SMARTboard lesson presentation (8 slides)
PowerPoint lesson presentation (6 slides)
1 homework assignments
1 lab experiment worksheet

Presentations serve as lesson plans that guide the teacher through the entire lesson. Presentations include links to related YouTube videos to increase student engagement (I can help you use YouTube videos in your class, even if your network blocks such sites, just ask).

'Ask a question' if you need a PowerPoint file instead and I can probably re-upload an adjusted file quickly.
