In this craft worksheet, young scholars learn about common seashells (especially in Florida) by first reading and looking at the photographs of 6 common shells. Students follow detailed instructions to construct a seaside wind chime of...

Students explore the structure of a typical and generalized grass plant. They visualize the structures of a grass plant by constructing a paper model. In addition, they identify the names and structural relationships of the parts of a...

Students determine the weight of paper waste generated by the class. They brainstorm ways to reduce and recycle. They make their own paper to demonstrate recycling. This lesson is very effective in demonstrating how recycling works.

Young scholars examine tension and compression by manipulating objects that are strong in each but not in both. Students apply their observations to the construction of a model of a beam bridge, suspension bridge, and inverted triangle...

Young scholars explore Native American weavers by making a pattern, repeating that pattern on a strip of paper, and weaving the paper onto a loom.

Students learn the difference between perimeter and area by watching a video and a hands on activity.

Pupils collect snail shells, measure and record their lengths and if they are occupied by a hermit crab. They discover if their is a size difference between occupied and unoccupied shells.

Middle schoolers identify common wildlife by investigating their footprints. They examine where and how to look for signs of animal activity. They create casts of animal tracks and gather information about the animal from the location it...

Students observe artifacts from Fort St. Louis at a website in order to make inferences about the people who lived there. They paint pottery in the style which might have been used by one of the cultural groups who inhabited the fort.

Students observe and describe changes in an environment when some of the components are changed. They recognize the process of succession by preparing a miniaturized environment in which a variety of plants and seeds are grown.

Students are shown slides of Yosemite and explore how the valley was formed by performing an experiment. Instructions on how to set up the lab are included. They can be assessed orally or by writing a report on the outcome of the lab.

Young scholars create DNA models using colored construction papers. In this biology lesson, students identify enzyme restriction sites. They model how DNA plasmids replicate when taken up by a bacterial cell.

High schoolers build an organic waste methane generator and learn by running a scientific experiment to see what happens when people alter nature's way of recycling.

Students review different units of measurement that would be used to measure height. They compare their height to that of Abraham Lincoln by working with a partner to make a life size tracing of each other and measuring their height.

Fourth graders explore basic measurements by analyzing their own bodies. In this human anatomy lesson, 4th graders identify the units used to measure a human body such as centimeters, inches, ounces and pounds. Students complete a...

Students observe how an image falling on a CCD array is divided into individual pieces, by the property of persistance of vision.

Students visualize what happens when a 2 foot long piece of string is put through the middle of a cardboard circle with rainbow colors on it. The string is wound up by the students and then students have to observe what happens when the...

In these story problem worksheets, students read the story problem 'Mystery of the Peculiar Zoo.' Students use the information within the story to then solve the problems. Students use their multiplication and division skills to...

Students read a New York Times article as a class and discuss how groundwater near a nuclear test site may have been contaminated. They explore how groundwater contamination can spread through aquifers by participating in a simulation.

Pupils research uniforms worn by athletes in the U.S. They list the colors used by teams, chart the data and create a Venn diagram, and design their own sports uniform using a paper shopping bag.

Students collect objects that represent themselves. In a class discussion, they consider how they are seen and understood by others. Students create two sculptures, one of how others see them and another of how they see themselves.

Students complete a KWL chart on what they know about glaciers. Then they gather together around a table containing Jello and Cool Whip cookie mixture and are introduced to the parts of a glacier by observing this model.

Young scholars build a robot out of a 3-¿¿ inch floppy disk drive, two floppy disks, and some other miscellaneous supplies. They apply information they gather about electrical circuits from a web-based circuit design program.

Students experiment with currents caused by temperature variations that simulate the origins and flow of polar bottom currents. They discover water density is affected by temperature and salinity, resulting in deep water currents.
