Constructing Phylogenetic Trees: The Whippo Story part of Examples
An interactive lecture in which students use data on feeding habits and habitat, skeletons, and DNA sequences to draw phylogenetic trees.
Will the egg break? part of Examples
This is a discrepant event that can be used to help students understand applications of the momentum-impulse theorem. Students are first asked to predict and hypothesize what will happen when an egg is thrown into ...
Modeling emf, Potential Difference, and Internal Resistance part of Examples
Through class discussion and think-pair-share questions, this activity helps students come to understand the difference between emf and potential difference in electrical circuits. These concepts are broached within the context of internal resistance of batteries.
Rutherford's Model of the Atom part of Examples
Students are asked think-pair-share questions to predict the interaction of alpha particles fired toward the nucleus of an atom. An online applet is used to illustrate the interaction and test students' ideas for the causes of the interaction. This activity uses a resource in the comPADRE partner collection.
Measuring voltage and current in a DC circuit part of Examples
These exercises target student misconceptions about how to properly measure voltage and current in simple DC circuits by letting them investigate different meter arrangements without fear of damaging equipment. These activities also are designed to lead to other investigations about simple DC circuits.
Projectile and Satellite Orbits part of Examples
Gravitation introductory activity with interesting animation. The activity allows the student to revile the connection between the initial speed and the shape of satellite orbit.
