Do not overlook this set of lessons just because your school does not have a data analysis system. There is plenty of material here to administer a complete mini unit on the formation, distribution, and properties of coal. Since it...

Fred thinks his test score is high enough to earn him a certificate. Given the mean and standard deviation, use properties of normal distributions to calculate Fred's percentile ranking and see if he is right. Consider having your class...

Pupils create trading cards for elements in the Periodic Table. Initially, they are introduced to the Periodic Table of Elements and the concept of elements in the world around us. After dividing into groups, learners use the Visual...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

Learners explore the strength of intermolecular attractions. They make slime and compare the difference in the physical properties of sheet and powdered polyvinyl alcohol with polyvinyl acetate.

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...
