Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Students problem-solve how to log five acres. Working in pairs, they construct models of logging sites before and after the trees are harvested. they paint their models and include other environmental details.

Students develop their own research questions dealing with specific variables provided by the instructor; students conduct bird counts using two kinds of birdseed, and analyze possible effects such as abundance or diversity.

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

Students demonstrate what happens when nature takes back land after humans have managed it. They find an area in the schoolyard, and mark it off with a boundary. Students build a simple fence with string and stakes. They put up a sign...

Students calculate the tangent ratio given a right triangle. For this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.

In this variables worksheet, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

In this map making worksheet, students learn about the science of making maps, which is cartography. They then answer the 11 questions on the worksheet. The answers are on the last page.

Students find math concepts in every day items. In this math concept lesson, students take ten photographs of things they find interesting. They analyze the photographs to find hidden math concepts such as counting, lines, angles,...

High schoolers differentiate between similar and congruent triangles. In this geometry lesson, students identify the angles of triangles using the similarity theorem. They apply concepts of triangles to the real world.

In this boy scout:  first class rank learning exercise, 8th graders research the requirements for this level using the websites listed, and answer 14 detailed questions about using a compass, camping, meal planning, safety, first...

First graders investigate plant growth and examine what factors contribute to plant growth. They keep a class chart of plant growth and write about and illustrate their conclusions.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This part...

What tree is big enough for a car to drive through? Figure it out with this NCTM math challenge on measurement. Find out why understanding measurement is important in everyday life. A one page activity from the NCTM Math Challenges for...

Offers instructions in how to use a clinometer, an instrument used by foresters for measuring angles in order to determine the height of a tree. The mathematics behind a clinometer is also explained.

[Free Registration/Login Required] Students use similar triangles to determine the height of the base of a tree house. Click learn more to watch a video and click challenge me to answer a practice question.

Students learn about trigonometry, geometry and measurements while participating in a hands-on interaction with LEGO MINDSTORMS NXT technology. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the...

Just how tall is that object? In this lesson, young scholars will participate in an outdoor group activity using shadows to extend their knowledge of proportions to solve problems dealing with similarity. The cooperative learning groups...
