Kit Information

Grade: 6
Type: Physical Science
In this unit, students will utilize a variety of observation and experimentation techniques in order to understand the concepts of density, displacement, and weight as they all relate to buoyancy. Students will participate in exciting hands-on activities to include examining and testing the buoyancy of a variety of objects, testing how salt water affects buoyancy, and comparing the weight of objects when either out of water or submerged in water. Students will also be able to use spring scales in order to measure the buoyant force on fishing bobbers. Additionally, clay boats will be formed and placed in water so that students can observe the relationship between form and buoyancy. These engaging activities will encourage students to use predicting, investigating, and analyzing skills.
