Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

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 activity focuses on...

Step aside, fancy glasses... it's time to create a solar eclipse viewing camera of your own using nothing more than a milk carton. 

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Use primary text documents to learn word roots. Learners listen to a reading of the Declaration of Independence and highlight words they don't know. They compile these words and guess their meanings. They discuss roots, prefixes,...

Hold a free-throw shooting challenge in your engineering class! Each team must design a contraption that will fire off a "robot arm" or, more specifically, a catapult, to send a Ping-Pong ball into a basket. Use this as an opportunity to...

Turn young mathematicians into landscape architects with this four-lesson series on area and perimeter. Beginning with a basic introduction to calculating perimeter and area using non-standard units of measurement, this...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Apply scientific principles to designing an experiment to study organisms living on the coral reef in our oceans. Through reading, individuals learn about the coral reef ecosystem and important factors that affect its function....

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

How do magnetic fields differ? Allow scholars to see the difference between 2-D and 3-D magnetic fields. They construct models of both and observe how they are similar and different. It is the fifth installment of an 18-part unit.

Who needs a barbecue grill to cook hot dogs when you have the amazing power of the sun at your disposal? Engage young scientists in learning about solar energy with this fun activity that turns a used Pringles can into a solar...

Life in the Bering Sea, food webs, and the ocean ecosystem are introduced with a map activity. The lesson starts as kids explore maps and images of the Bering Sea, then it kicks into high gear as they start to discuss the types of...

Operating a vehicle remotely can be difficult, especially when the vehicle is on another planet. Young engineers get a feel for some of the real-world challenges as they work to program their rovers (blindfolded group members)...

Hang a strip of foil on a stand and form a loop out of it. Then attach the clips of a battery-operated circuit to the loop to see its sides repel each other. This simple demonstration is applicable and easy to add to your lecture on...

Over a span of two weeks or more, mini meteorologists record weather-related measurements. What makes this particular resource different from others covering similar activities are the thorough details for the teacher and printables for...

Young entomologists construct three types of insect traps—pitfall, pollinator, and panel—before setting their traps out and observing what they caught. They then observe what types of insects the different traps attract.

Four intriguing and scientific activities invite learners to explore the natural resources of their town. The activities cover concepts such as genetic traits, organizing species in a taxonomy, the differences between different species...

Through watching several classic air pressure demonstrations, middle schoolers determine that high pressure areas move toward lower pressure areas, heated air causes a drop in pressure, and forces exist when pressures are unequal....

Study all things weather with a packet of weather vocabulary activities. The 12-page packet includes three crosswords varying in difficulty, a mixed letter sort, a sentence sort, weather word search, and fill-in-the-blank sentences with...

An all-encompassing, fully interactive, gorgeously animated model of the heart can be used to teach cardiac anatomy, physiology, and even a touch of epidemiology.

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

In spring, the Bering Sea turns green due to phytoplankton, which live at the surface, experiencing a population explosion. Groups of scholars play a food chain game, writing down food chains as the game is played. After five to six...
