Young scholars, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and...

Students, after reading the Web page Gas Properties Definitions, complete the activity to demonstrate an understanding of the properties of gases.

Second graders read ead the book The Wump World written and illustrated by Bill Peet. Discuss with the students how air pollution can make your eyes water and cause shortness of breath. Students discuss air pollution and give the...

Students conduct an experiment to evaluate the accuracy of their senses.

Fourth graders explore meteorologists. They explore symbols on a weather map and make five day forecasts.

Students work together designing and building their own beams. They discover the concepts of stress and strain. They participate in a competition to determine the best beam.

Ninth graders compare the nature of forces of gravity, lift, thrust, and drag. They select proper materials for making a kite and attach a proper tail. Students interpret and summarize the observations made during the flight of the kites.

Students explore the relationships among the lengths, areas, and volumes of similar solids. They also discover what effect doubling the dimensions of a figure has on the resulting area.

Students create their own ice cream sundae given various toppings from around the world. In this foods and languages of the world diversity lesson, students develop an understanding of diversity in culture, family structure, ability and...

Students examine images from space.  In this third from the Sun lesson plan, students examine images from, Landsat, the satellite launched by NASA in 1972.   

Students have the opportunity to participate in a simulation that enables them explain the characteristics of a Market Economic System.

Students discuss movement of air currents and then experiment to create visible models of air currents. Students connect the model to weather patterns.

Students think about what causes the seasons to change, reflect on what they know about seasons and how their lives affected by seasonal changes.

Students see the difference between weight and mass when they examine the method of measuring each of them.

Students choose an interesting problem related to space travel and then design a plan to solve the problem. They present their solution to the class.

High schoolers find the approximate area of the court order on a current map of Delaware. They draw a layout of their school and decide where a new hallway or outside pathway would be most needed.

Students explore the investments undertaken by the "thrillionaire" Paul G. Allen, and propose future areas of high-tech scientific investment for Mr. Allen to pursue.

Students observe and identify the various types of clouds. They compare clouds to clouds on a chart, and in small groups compose and present a group poem about clouds and weather.

High schoolers explore the reasons behind the Tulsa riot. They are illustrated the "living" nature of history through examining the recent investigation into the Tulsa riot. Students are introduced to a specific outbreak of racial...

Students discuss forms of transportation in Delaware during 18th Century, find approximate area of court order on current map of state, draw layout of their school, and decide where new hallway or outside pathway would be most needed.

Students practice forward and backward counting.  In this counting activity, students calculate how many objects in a bag by counting forward and then count backward to check.

This is a culmination activity used after students have studied Bernoulli's Principle as part of a unit on forces and fluids. Students will use the Internet, textbooks, library resources and their cooperative learning group to design...

Learners will experiment with different styles of paper airplanes, create questions to test, and design experiments that will allow them to gather data related to their question. They will record their data, using graphs where...

The purpose of this lesson is to help students understand the relationship between the mass and the weight of an object. Students will study the properties of common materials and why airplanes use specific materials.
