Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

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,...

Students are introduced to the topics of electric currents and resistance. In groups, they distinguish the difference between conventional and electron flows and state Ohm's Law for electrical components. They calculate the resistance of...

This performance task tests students' ability to measure length, volume and temperature accurately in a lab setting.
