Science Specialist Deborah Landon has been guiding students across grade levels in exciting water-based experiments, sparking curiosity and discovery in the Science Lab.
The 5th-graders explored how to measure an object's volume by seeing how much water it displaces in a graduated cylinder.
Using the formula D=m/v, they calculated density to predict whether objects would float or sink in water. By finding the density, they were able to make predictions about an object’s buoyancy in room temperature water. Math and science go together!
In another fun challenge, they tested different brands of paper towels (kept secret for fairness) by soaking each in water, then squeezing it into a graduated cylinder to see which absorbed the most water.
"After conducting the tests, all of the lab groups share their data to determine the winner," said Ms. Landon. "This gives us a fantastic opportunity to reinforce those statistic skills with finding the mean, median, and the mode of the data and to determine and eliminate any outliers that may skew the results."
Before the experiment began, Ms. Landon talked to the class about how scientific research is done. Experiments must be repeatable by other entities in order to verify their validity. In order for that to happen, the exact method on conducting an experiment must be documented. The students followed their precise steps for conducting the experiment.
