Sixth-Grade Scientists Experiment

Sixth-Grade Scientists Experiment
Density Experiment This week students in Ms. Jeane’s sixth grade Science Class were challenged to explore what they are learning with a hands-on lab to help them visualize the concept of density.  Students are learning how to calculate density using the formula mass divided by volume equals density.  During their experiment our Sixth-Grade scientist measured specific volumes of water in a graduated cylinder.  They weighed the water once it had been precisely measured.  Armed with their findings, students created a chart that showed the correlation between the increasing volumes and the weight of the water.
Density Experiment Density Experiment
Density Experiment In a follow up experiment, students were given a beaker and some raisins.  They were told that they would be adding a clear soda to the beaker and asked to create a hypothesis about what would happen with the raisins once the soda is added.  One student hypothesized that the raisins would stick together and sink, another that air pockets would make the raisins float.  Some thought the raisins would absorb the liquid and become too dense to float.

Once the soda was added students watched as the raisins seemingly danced up and down in the liquid.  After a period of observation, Ms. Jeane asked students to write a conclusion on what they believe caused the phenomenon.  Once conclusions were complete Ms. Jeane explained that tiny bubbles of CO2 were attaching to the raisins which would cause them to float.  Once at the top, bubbles would begin to burst which would cause the raisin to sink.

Having had a visual representation of mass, volume, and density our Sixth-Grade scientists are ready to continue exploring and learning.
