Which intermolecular force is the strongest? Scholars test the relative strength of London dispersion forces, dipole-dipole interactions, and induced dipoles using a simulator. The interactive allows learners to pull on paired molecules...

It does a mind good! Learners experiment with a combination of food coloring, detergent, and milk. They observe how the food coloring reacts with the different liquid combinations and relate their observations to the charges on the fat,...

Learners determine whether the objects shown are inside or outside. They check the box that is near objects that are located outside of something. They then draw candies outside of a jar. 

Tenth graders develop positive attitudes toward older adults. They examine the continuity of life and its impact on youth to improve quality of life and develop occupational skills related to mature adults.

Middle schoolers use a computer to complete activitites about slope. They find the slope of mountains, roofs, and stairs using rise over run. Pupils are shown different types of slopes and have to identify if the slope is positive,...

Students work in small groups to: make a mental map of the world by tearing paper shapes of the seven continents and locating them on a flat surface in their relative positions, compare their finished mental map to a reference world map,...

Your teenagers may have heard of fracking, but do they really know what it is? And could they debate the benefits and risks? Educate your environmental science class with a lesson about hydraulic fracturing, non-renewable energy...

Most water fountains are designed to keep the water inside the fountain, but how are they designed to shoot up and out without the water leaving the fountain? Scholars vary the launch angle, fountain height, launch speed, and...

What's the likelihood of your class understanding probability maps? Young scientists explore the concept using a virtual dartboard in an interesting simulation. The darts establish a pattern around the bull's-eye, which provides a visual...

Everyone enjoys projectiles, and predicting where they land helps with future hands-on labs. Incorporating gravity into horizontal trajectories through both conceptual and mathematical practice helps scholars understand real-life...

Young mathematicians connect vectors to geometric shapes by watching a video that expresses vectors in relation to the sides of geometric figures. They then apply what they learned by completing a worksheet of practice questions.

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Use the area of polygons to calculate the area between curves. Pupils calculate areas under income and expense curves by filling the space with squares and right triangles. Using that information, they determine the profit related to the...

So many of life's problems could be resolved with proper communication. Teenagers work on replacing negative messages with positive messages, active listening techniques, and communicating assertively in a series of classroom activities.

Every time you pause while reading, you should insert a comma, right? Not necessarily. Using a comma to indicate a pause is just one of the myths addressed in a handout related to the pesky punctuation mark. After reviewing common...
