Learners create a timeline that explains how ancient cultures used artifacts. In this Relative Dating in Archaeology lesson, students examine artifacts and draw conclusions about their origins. Then learners analyze antiquated objects or...

Students create a 3-D topographic map.  For this map building lesson, students use cardboard to create a topographic map of the Catskills mountain region.

Second graders become familiar with the geography of Arkansas and analyze why it is a good place for certain crops to grow.  In this rice lesson, 2nd graders list reasons Arkansas is a good place to grow rice. Students become...

In this algebra worksheet, learners rewrite word problems using an algebraic equation to find the answer. There are 14 questions with an answer key.

Young scholars identify he proportion of a cereal box. In this algebra lesson, students define the relationship between patterns, functions and relations. They model their understanding using the cereal box.

Students examine soil erosion and what causes it.  In this soil lesson students complete several experiments on soil erosion and the weathering process. 

Pupils study the effects of water erosion on soil by gathering and analyzing data during an experiment. They decide on appropriate units of measurement to apply in problem solving.

Students explore coffee and coffee plantations. They view a Power Point presentation of what coffee looks like, where it grows, and how it is harvested. They discuss the environmental impacts on growing cofee and how it compares to...

Learners play a game of marbles outdoors on an iced area. They begin by playing a warm-up game of tag and proceed to sliding their marbles on an iced surface into holes. They attempt to gain points by sliding the marble into holes of...

Young scholars describe how cosmic rays achieve high kinetic energy via conservation of momentum.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.

Third graders study maps of the United States locating Louisiana, the East Coastal Plain, the Mississippi Alluvial Plain, the West Gulf Coastal Plain, and five of the main rivers. In this geography lesson, 3rd graders create a...

Students determine the monotonicity and concavity properties of a function, then apply the First Derivative Test and draw conclusions about the first and second derivatives from these properties.

Students, in groups, observe the effect of water and ice on surface features of the land. They alsoexplore erosion and deposition.

Students discuss the topic of streamflow and how it occurs. They take measurements and analyze them. They interpret data and create their own charts and graphs.

Third graders explore the operation of a Christmas farm and how trees are shipped. After taking a tour of a Christmas tree farm and researching transportation, location and cost issues, 3rd graders create a map to show the distribution...

Ninth graders investigate the factors that increase soil erosion. They identify how the environment is affected by erosion. In small groups, 9th graders research erosion problems in various locations. Groups brainstorm ideas to help...

Students determine the spring constant by conducting an investigation. In this physics instructional activity, students collect data and create a graph of force vs. displacement. They compare the results of two different methods to find...

In this activity, students identify whether a slope field approximately reflects a differential equation. They also determine whether a potential solution fits the slope field.

In this activity, students learn what a slope field represents in terms of dy/dx. Students create a slope field for a given differential equation

Differential equations, slope fields, and particular solutions are investigated in this practice problem. The handout is available in PDF format and includes a slope field.
