The first nine slides visit the history of our understanding of atoms. The next several outline the structure of atoms. Subatomic particles, electron configuration, and diagramming methods are introduced. This is a neatly organized...

Fourth and fifth graders will love showing what they know about the planets and our solar system. This game is fashioned after "Who Wants to be a Millionaire" and has the class work through fifteen different solar system related...

Geography is such a fascinating subject for learners of all ages. Prepare learners with good guiding questions, which they can use while reading their texts. Each of the provided 13 questions requires a full paragraph response on the...

How do major religions, including Judaism, Christianity, and Islam, differ in how they view the role of individual freedoms within society, the definition of morality, and the importance of politically satisfying the greater...

From the apple on your desk and the coffee cup in your hand, to the cabinets along the classroom wall, basic three-dimensional shapes are found everywhere in the world around us. Introduce young mathematicians to the these common figures...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

In the hustle and bustle of everyday life it's easy to forget that geometric shapes are everywhere in the world around us. As they complete this shape identification worksheet, young mathematicians realize that many common real-life...

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and...

The biogeochemical cycle ... no physics? The fourth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces the biogeochemical cycle by having pupils simulate movement between Earth's...

Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...

Students examine the historical, social, cultural and economic context of Charlotte Perkins Gilman's story, The Yellow Wallpaper. Students determine the place of the middle class woman and her role in society.

Examine the Israeli-Palestinian conflict. Learners research the 50 Years War and analyze the conflict through the point of view of both sides They attempt to develop a plan to bring peace to the region of Israel.

High schoolers explore the overall strategies pursued by the Japanese and the Allies in the initial months of World War II. What each side hoped to accomplish what what actually happened forms the basis of a comparison made in this...

Students examine how the European voyages of discovery influence American culture even today. They map eighteenth century Europe's impact on the United States.

Sometimes the New Order becomes synonymous with its implications for European countries, but what about its consequences for East Asia? The final instructional activity in a four-part series teaches scholars about World War II. High...

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Students research the impact of European voyages of discovery and colonial influence on different aspects of American culture. They access a number of online sources and reference maps to trace the influences of England, France, Holland,...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Shapes are so fun! Little ones explore, identify, and create shapes using tangrams or pattern blocks. The activity is intended to stimulate critical thinking while engaging learners through play and shape identification. Each child will...

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...
