Making a Battery
Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...
Curated OER
A Moving Experience - Forces and Inertia
Students consider the first part of Newton's First Law of Motion, the Law of Inertia of objects at rest, which states that every object remains at rest unless acted on by a force. They perform hands-on experiments which demonstrate this...
Curated OER
Slime and Intermolecular Attractions
Students 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.
