Young geographers discover not only how to read and recognize coordinates on a map, but also gain a deeper understanding of latitude and longitude and how climate changes can vary significantly across latitudes.

Students explore lunar eclipses and discover how to predict an eclipse the same way that ancient people did. They examine dates of recorded eclipses and find a pattern. Students apply an algorithm to the pattern.

High schoolers examine tesselllations and their geometric properties. They have a better knowledge of polygons, can identify types of symmetry in tessellations. Also students use visulization, spatial reasoning, and geometric modeling...

Students explore one to one number correspondence. In this early math lesson, students make observations about and classify plants in order to gain an understanding of using numbers to describe their world.

Students identify shapes that will tessellate. They construct a tessellation using transformations. Students identify transformations in tessellations. They identify applications of transformations such as tiling and fabric design.

Students go on an imaginary fossil hunt. They follow a script read by the teacher, students "find" (remove from envelope) paper "fossils" of some unknown creature. They attempt to reconstruct fossil pieces into an animal.

Learners put their growing understanding of the scientific inquiry process to work. They use paint to implement their plans to experiment with how changing one aspect of the fractal making process influences their appearance.

Students make models of protiens using wire and paperclips. They are given step by step instructions with lots of information about proteins throughout the directions. They make the three basic structual elements of proteins;...

Students observe a variety of sounds which can be heard within their schoolyard habitat by sitting quietly by themselves for five minutes, listening, and then recording the sounds around them by drawing them.

Students observe how sound waves would look and behave if we could see them. They determine ways the model is accurate and inaccurate based on actual sound waves.

Students study earthquakes, monitor seismic activity using the Web, and plot real-time activity. They examine movement of the Earth's tectonic plates. They create an earthquake preparedness project.

Fifth graders construct a water compass to investigate the effects of Earth's magnetic field and other sources of magnetism. They predict, observe and draw conclusions from their investigation.

Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.

Young scholars explore the five common turtles that are native to the eastern United States. They investigate each turtle's characteristics, environment, means of protection, eating habits, and show how they can help these turtles survive.

Young scholars examine the differences between a virus and a bacteriophage. They explore various websites, identify the parts of a virus and a bacteriophage, and construct a model of a virus or bacteriophage.

Young scholars examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino...

Middle schoolers build a Colossal Classroom Cladogram of vertebrate evolution. After putting it together, they show the gradual, mosaic accumulation of the traits which we, as humans, possess.

Students collect and examine the life cycle of monarch butterflies. They also tag butterflies and release them as part of a nation-wide project to study monarch butterfly migration.

First graders ponder the question of how plants help their lives. They observe and compare properties of several different plants. Differentiate between living organisms and nonliving objects.

This plant structure and function PowerPoint addresses the main organs and the factors that affect its development as well as going into detail about the specializations at a cellular level.   The cell functions and system...

Students take a walk around the schoolyard looking at and identifying the trees. One leaf for each tree is collected. A chart is developed that represents the population of trees on the school ground. They keep journals and write an essay.

Fourth graders study the uniquely diverse structural design of leaves and demonstrate knowledge of interdependence between structure and environment through research, laboratory activity and written summary.

Students examine the different types of tests used to measure the environmental effects of hazardous waste. They work together to determine the impact of pollution on different ecosystems. They read a case study and answer questions to...

Students consider two sets of simulated fossils (caminalcules) that are provided as cutouts. They arrange them on two time scales. One set produces a visual example of gradualism, the other shows punctuated equilibria.
