Students study the different types of metals.  In this investigative lesson students watch a demonstration on the effects of temperature on atoms and take a tour through baone matter.

Students measure shadows and explore the altitude of the sun.  In this sun lesson students will graph the length of shadows and solar altitude against time. 

Students conduct an experiment to measure the diameter of the sun. In this astronomy lesson,  students construct a simple equipment to collect scientific data. They calculate the sun's diameter using a given formula.

Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.

Students take an imaginary hike in two opposite directions along a lake. They view and interpret satellite images and discuss the pros and cons of hydroelectric dams.

Students create and analyze graphs using archived atmospheric data to compare the ozone levels of selected regions around the world.

Third graders study clouds and how they are formed. They write acrostic poems about clouds and analyze and graph temperature data collected during varying degrees of cloud cover.

Students identify the three major cloud groups. They are introduced to the three main cloud types and spend a week making and recording observations of clouds. Students produce a graph that presents their findings and conduct research...

Students consider a variety of well-known proverbs that refer to the weather. They research the scientific validity of these proverbs, conduct interviews about public perception of the proverbs and summarize their findings in writing.

Learners conduct an experiment to determine if water level is affected by a change in oxygen level or air pressure.

Fourth graders, in groups, use books to identify types of rocks. They examine the rocks and complete rock evidence charts. Students compose definitions for each rock type and determine uses for igneous rocks by early mankind.

Students discuss the threats facing migratory species and track the seasonal journeys of wildlife in real space and in cyberspace. Once they have gathered information from several sources, they create a portfolio to share with others...

Middle schoolers interview the senior citizens in their community. While interviewing them, they identify perceptions they have about the local climate. Using the internet, the compare the results of the interview to those of public...

Students review the planets and major moons in the Solar System. In groups, they research and describe the various phases of the moon. They record their observations of the moon phases over a specific period of time and use the...

Students explore how smaller systems exist within larger systems as they build a collage of their place in space! Invite the students to display their posters and talk about their systems and systems of systems.

Students investigate the concept of a watershed. They conduct research into the concept using a variety of resources. Students take a field trip to a local watershed to make observations. The outcome is a report concerning the outside...

Third graders make and maintain a mini terrarium. They keep a daily journal of what happens in their terrarium and record daily observations and measurements.

Students are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to view...

Fifth graders study how simple machines can help us alter forces and discuss the term mechanical advantage. They then identify dysfunctional simple machines and discuss in groups how the dysfunctions will decrease the effectiveness of each.

Learners write and communicate mathematically with their classmates. They discuss the mathematics that it took to allow us to conquer space and land on the moon. They sketch a plaque they would leave on the moon.

Students work together to determine a new site for a harbor. Using the Internet, they research the impact of an oil spill on the oceans and wildlife. They present their findings to the class and a solution to the problem.

Students perform experiments to explore differences in wind speed and forest density. Through experimentation and observation, students realize that changes in vegetation affect the atmosphere and wind conditions. They create a model...

Students comprehend the physical properties of pressure and Boyle's Law by designing a depth gauge. They construct a capillary depth gauge and calculate the calibrated depth marks of the capillary tube. They determine the margin of error...

Students design and construct an imaginary animal that is perfectly adapted to a particular type of biome. They give the animal a scientific name, place it in a phylum and write descriptions about its behavior, reproduction, foraging,...
