Students calculate the radius of the earth. They use the method and data suggested by Eratosthenes. They investigate the interrelationships among mass, distance, force, and time through experimental processes.

Students explore a variety of ways of how to care for the environment in the nine lessons of this unit. They observe how to be responsible "Earth Kids."

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Eighth graders investigate the regular motions of the sun, Earth and the moon and explain how these are related to days, years, seasons, eclipses, tides and moon cycles. They participate in an exercise where they explore the...

Students analyze the theories of the formation of the universe and solar system. Students analyze planetary motion and the physical laws that explain that motion: Rotation, Revolution, Apparent diurnal motions of the stars, sun, and...

Second graders discover how to use longitude and latitude to locate specific sites on Earth. They compare old and new ways of locating specific places, and discover how latitude and longitude coordinates are used to locate places on Earth.

In this science worksheet, students answer the trivia questions that focus upon various planets of our solar system. They also define what a star is.

Young scholars identify questions and problems in the earth and environmental sciences that can be answered through scientific investigations. They design and conduct scientific investigations to answer questions related to earth and...

Students analyze theories on how the solar system was formed.  In this solar system lesson plan students explain the rotation and revolution of motion. 

Students study the planets of the solar system. Students observe a model of the solar system, and name each planet, in order. In pairs, students write acronyms to assist in remembering the plants in order and share them with their...

Students compare things that are greater than, less than, or equal to, compare the Earth to other planets, and list planets from greatest size to smallest size.

Students examine how Earth-Sun relationships affect Earth's energy balance and the pattern of world temperatures. Students study a Surface Temperature Regions map and write a paragraph describing the temperature pattern from the Equator...

Sixth graders explore angles, triangles, and investigate the circumference of the earth. They participate in a Webquest, access data bases, and communicate with other students through an on-line project site involving the circumference...

In this safe drinking water learning exercise, students answer 5 essay questions pertaining to city water systems and safe drinking water. There is no text and no information here.

Your learners have probably heard of climate change, but do they really understand what it is? Study the history, details, and future implications of global warming and the greenhouse effect with a set of activities designed for an...

Your pupils may believe that you and their parents are the oldest things in the universe, but surprise! There are elements of the universe that are even older. Elementary scientists create a class timeline to demonstrate the...

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

The sun isn't just a ball of yellow! Young scientists learn about the features of the sun using a hands-on modeling activity. They build models of the sun using common household items to represent sunspots, solar prominence, and the...

The San Andreas Fault is the largest earthquake-producing fault in California. In the seventh lesson plan in the 20 part series, pupils create maps of California, focusing on the San Andreas Fault system. The comparison of where...

Students examine and calculate the percentage of potable water remaining on the earth. In this ecology and geography lesson plan, students brainstorm the main factors affecting water distribution. Students use mathematical problem...

Learners study the amount of potable water on the Earth. In this water instructional activity, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have...

It may be tricky for a young mind to conceptualize that less than 1% of all water on earth is useable for humans to drink. Simulating the amount of fresh water available on earth by removing measured amounts of water from a five-gallon...

Young scholars research the solar system and it's characteristics.  In this solar system lesson plan, students are broken into 4 groups, each assigned a specific part of the solar system.  Young scholars use the Internet to...

Students observe and analyze how pulleys work and how a double pulley can make work easier. In small groups they use a fixed pulley system and a double pulley system and draw a picture of how their pulley system functions. Students...
