Ready to take your chemistry class on its first big lab adventure? Dive in to differentiation between chemical and physical changes with a thoughtfully designed set of experiments! Partners conduct a series of reactions, describe their...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Time to shake up the status quo with a presentation that describes Le Chatlier's Principle and has pupils examine situations in which equilibrium is upset. Four examples show different stresses to the reaction and the resulting shift. 

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes actually...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

How do Olympic runners succeed in physically demanding events like the 400-meter dash? Physiology scholars explore the relationship between acids, bases, and the muscular system through a scenario-driven activity. The lesson focuses on...

Scientific method, linear measurements, friction, inertia. Imagine learning scientific vocabulary in an ELA class. Before researching and developing a presentation about simple machines, class members build a common, but decidedly...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Given a particular direction and velocity, what force can make a ball swerve into a goal? This visually engaging video illustrates the physics that occur when a ball rotates on its axis while moving in a particular direction, also known...
