Students consider that under certain conditions in nature tend to remain the same or move toward a balance. They observe populations and determine the functions (e.g., de-composers, producers, consumers) they serve in an ecosystem. They...

In this specific heat worksheet, learners are given examples to find the specific heats of substances and to use the specific heats to find the changes in temperatures of substances. Students solve eighteen problems using what they...

Students discover that charge movement through a circuit depends on the resistance and arrangement of the circuit components. In a hands-on activity, students build and investigate the characteristics of series circuits. In another...

Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.

In this ecology worksheet students complete a crossword puzzle that incorporates all of the ecological vocabulary in the word puzzle.

Students research separate elements of the theory of Plate Tectonics, then share that information with each other, drawing conclusions from the culminated information.

Students gain an understanding of the difference between electrical conductors and insulators, and experience recognizing a conductor by its material properties. They build a conductivity tester to determine whether different objects are...

Learners are able to use inquiry to answer the essential questions. They are able to predict and test configurations of a battery, bulb, and wire that make the complete circuit. Students craft a group and individual theory of a...

Students select an instrument and create a musical composition. For this musical composition lesson, students invent an original piece of music that is 16 measures long. Students hum and record their pieces.

In this tropopause worksheet, students read about the temperature of the air in the tropopause or the layer of the atmosphere closest to the Earth. They answer four critical thinking questions about this layer and the energy changes that...

Learners describe how the sun heats the Earth, explain the nature of infrared light, explain how thunderstorms are formed and use infrared maps to predict severe weather.

Learners are introduced to the reflective properties of light and use mirrors to make light from a source reflect onto a specific target. They take turns and record the amount of time it took to correctly reflect the light.

Eighth graders visit the Virtual Earthquake Web site and complete activities that demonstrate how geologists locate the epicenters of earthquakes. The site uses actual data from historic earthquakes.

Students use NASA satellite data to see cloud cover over Africa.  In this seasons instructional activity students access data and import it into Excel. 

Pupils explore how a whale's countercurrent flow of blood is an example of a heat exchange system and conduction. Excellent worksheet provided.

Students s identify the different trophic levels in the food chain and understand the importance of the energy cycle. They create a class food web using index cards and yarn and play a predator/prey game.

Young scholars examine the animals that live in trees. They identify their sounds, footprints and droppings. They draw pictures of the animals as well.

Students survey several concepts in literature, science, history, and geography as a preparation for the CSAP standardized testing experience. This nine lesson unit provides exposure to the format and content of the test.

Students are introduced to biomolecules and their roles in livin systems. They are introduced to the "Elements of Life." Students write down and define the "Elements of Life." They are asked why they think those elements are essential...

Learners explore food chains in the forest. In this food chain lesson, students listen to the story The Tree in the Ancient Forest by Carol Reed-Jones. They create a food chain to match the story and then create a food chain of...

Students explore physical education by completing a quiz in class. In this engineering lesson, students identify different ways engineering has made sports safer such as stronger padding and helmets, stronger equipment and smarter...

Students learn the idea of drama in their own lives; and then transfer that idea to the works of others in this series of lessons. They discuss the question of identity.

Fourth graders choose a simple machine and write about they way they believe it will work. Students experiment, write down procedures used and record observations. They will find a picture of the machine and add it to their report.

Students explore the amount of radiation in the Earth's atmosphere. They calculate the total amount of incoming and outgoing radiation over a day and determine how "balanced" the radiative system is over a particular location.
