In this hands on performance task, students apply what they have learned about density and buoyancy to measure and calculate how much sand can be added to a container and still float. Students will need to be able to accurately measure volume and mass to calculate density. After making their calculations, the students will test it out and write a CER argument explaining their thinking. This is a great culminating activity to see how well your students understand density.
·Small containers with lids (film canisters work well) ß They should all be the same size and type
·Graduated cylinders that are large enough to fit the container
·Gram scale or triple beam balance (measure to the nearest 0.1 gram)

This comes from my “Quick and Cl-Ev-R” series. Each activity is designed for students to practice writing scientific arguments with Claim, Evidence, and Reasoning based on real world data and experiences. Each activity includes a quick hands on activity or demonstration, data collection, and corresponding reading focusing on the scientific concepts presented in the activity.
