First graders identify both potential and kinetic energy in a game they play in the classroom. They listen as the teacher explains the difference between potential and kinetic energy when observing a simple machine. Using simple...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

Young scholars experiment with the amount of work required to break a piece of wood by hanging masses from a string attached to a thin dowel of wood. At the completion of activity, students calculate if a fast moving hand could break the...

Students explain necessity in using accurate instruments when measuring, and how measurements can be checked for accuracy. They make a six-inch ruler, design, test, and evaluate a system to measure work, and produce a table and graph to...
