This hands-on activity allows students at all grade levels and abilities to explore concepts of buoyancy by attempting to submerge a small object in a water bottle. Discovery should be supported by guided inquiry and open-ended questions to scaffold understanding and learning.
Once the students are done exploring and sharing their discoveries, reflecting on what they learned and asking questions about what they did not learn, a video showing how the experiment works will be shown and students will get an opportunity to view it.
There is also a detailed explanation of this experiment and a diagram illustrating how to conduct it for further study of the scientific concepts involved. Additional video links showing how to build a submarine in Minecraft and similar videos are also included for older and/or more advanced/tech savvy students.
Technology needed include a whiteboard, students cell phones for taking videos and sharing them using the KlipMix app, as well as Skype if collaborating with another class.
Performance assessments are embedded in the activities in the form of reviews and using inquiry and open-ended questions to assess understanding.
