In this online math instructional activity, students determine the radius, circumference, diameter and area of circles. This excellent resource allows the students to check their answers, and to get "hints" should they run into...

Seventh graders explore the skill of finding the increase and decrease of a quantity. Calculating the increase and decrease is covered by a percent. The proporition for finding a percent is also part of the lesson.

Pupils observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Students, in groups, measure and record each other's height. They identify measurement conversion methods and use online resources to convert measured heights to multiple systems.

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...

Students explore Earth science by completing a could identification activity. In this weather lesson, students discuss the different forms of measurement for the weather of Earth. Students discuss global warming and examine a list of...

Students discover the history of hot air balloons by watching one ascent.  In this physics lesson plan, students utilize a Montgolfier Hot Air Balloon from an earlier lesson plan and record the temperature, rate of ascent and the...

Students investigate the probability of global warming and the effects of global warming on the environment. They conduct Internet research and collect data, transfer the data onto an Excel spreadsheet, and create a presentation that...

Young scholars find out about the social changes that caused the collapse of important ancient civilizations in Central America, Mesopotamia, the southwestern United States, and western Africa.

Students are able to download, install, and use Image J image analysis software to quantify change over time in satellite images. They access and download satellite images for specific locations and times. Students set a scale (spatial...

Learners examine environmental change of land, water, and air, discuss Clear Skies Legislation, and experiment on solid compaction and resultant water filtration.

Eighth graders explore how to use the time zones in the United States and internationally. They use elapsed time to solve problems. Students calculate the time in various places in the United States. They discuss the 6 time zones in the...

Young scholars explain that heat energy in a material consists of the disordered motions of its atoms or molecules. They know and explain that transformations of energy usually transform some energy into the form of heat, which...

Students explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.

Students investigate that an unbalanced force, acting on an object, changes it speed or path of motion or both, and know that if the force always acts toward the same center as the object moves, the objects path may curve into an orbit...

In this density of the human body activity, students measure several parts of the body to calculate the body volume. Students convert the body volume to body mass and body density.

Students investigate the difference between potential and kinetic energy. They examine the formulae associated with both types of energy. They complete how quickly a pendulum with swing by converting potential energy into kinetic energy.

Students describe how demand differs from the quantity demanded, explain what the law of demand states and what demand schedules and demand curves illustrate while studying about economics. Also in retrospect, several writing scenarios...

Students brainstorm characteristics they associate with a community. In groups, they discover the role of a town square and create their own model. They also identify the various roles in keeping the community going and role play their...

Students define thermal equilibrium. They distinguish between internal energy and heat. Students describe how the quantity of heat that enters or leaves a substance is measured.

Eleventh graders study the history of immigration from 1850 to the present.  For this American History lesson, 11th graders compare the 1924 and 1965 immigration acts and give a reasoned opinion on each.  Students research,...

Sixth graders investigate the parts of a seed by using a digital camera.  In this botany lesson, 6th graders plant their own seeds in class and demonstrate the necessary attributes for growing a plant.  Students utilize a...

Students discuss scale diagrams and maps as well as the use of spreadsheets to find the best scale to use in a model before practicing scale and ratio problems on their own.

Learners investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.
