Striking a Balance

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Teams of Texas tourists gather into groups to analyze what they can do with $50 worth of an alternative fuel. They write checks, keep a balance sheet, and map out their sight-seeing route taking into consideration the location of...

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized lesson...

Designed to use when teaching adults preparing for their high school equivalency exam, the resource integrates reading practice, writing, and analytical thinking in every lesson. The unit covers 23 topics, but it only includes three...

Watch as the Secret Math Tutor demonstrates how to compute simple interest in a helpful math video. The narrator poses a word problem and formula before working through the problem, complete with explanation and work shown.

From burning wood for heat to riding a bicycle, converting one form of energy into another is an everyday process! Using a video clip, learners discover the sources of the thermal, mechanical, and electrical energies that make our lives...

These twenty various types of questions related to the cycling of matter and energy require learners to match each definition in column 1 with the correct vocabulary term from column 2. Then, students explain what is being demonstrated...

High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math activity, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.

This video segment adapted from A Science Odyssey uses a laser beam to demonstrate how light particles act like waves, illustrating Heisenberg's Uncertainty Principle. [2:07]

The fifth lesson in the six part series introduces units of energy including calories, Calories, and joules. Scholars determine the energy released when eating a snack and during activity.
