Estimating the Live Mass of Dinosaurs
High schoolers calculate the volume of scale model dinosaurs using a water displacement method. They use formulas to calculate the live mass each of the species of dinosaur. Then they complete and discuss a series of questions.
Curated OER
Estimating the Live Mass of Dinosaurs
High schoolers estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. High schoolers...
