Curated OER
Rock Density Lab
Students use a balance and weigh a rock sample. They weigh the rock suspended on a sling in a glass of water. They tabulate the rock's density using the two weights and compare the density of various rocks of similar sizes.
Curated OER
Are You a Trend Setter?
Learners are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same group.
Curated OER
Weighing a Dinosaur
Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
