Students measure the lengths of provided leafs to the nearest millimeter. Students identify trends in the data as well as sourced of inaccuracy and formulate additional questions that could be investigated to enhance their understanding.

In this customary length worksheet, students solve 5 multiple choice problems where they must choose the better estimate of customary length. Students then answer 9 fill in the blank problems and 1 word problem, where they must convert...

Learners discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.

Learners investigate the amount of rain that falls in their area through the construction and monitoring of a rain gauge. The gauge is observed for one week, recordings are made, and observations described in a chart.

Students study how to estimate the diameter of a tree, estimate the height of the tree using shadows, estimate the height of the tree using a ruler, and use tools for measuring trees.

Fourth graders estimate the measurements of trees using unconventional techniques.

In this similar figures instructional activity, students use proportions to solve 6 short answer and multiple choice questions.  Students use proportions to answer questions about map scales and height of trees given shadow lengths.

Students describe the characteristics of an ecotone. In this ecotone activity, students pick out their area and describe the visual appearance, conditions, ecosystem, biodiversity, predators, prey, and trees in their ecotone. They create...

Students view a 30-minute video activity to discover information about the characteristics of frogs and toads. They then transform themselves into frogs and participate in a Jumping Frog Jubilee. They work in groups of three to measure...

Students explore rain forests.  In this rain forest lesson plan, students participate in a "BioBlitz" of their schoolyard, observing and recording every living thing in a designated area.  Students visit websites about rain...

Students use protractors, strings, and straws to construct a device used to determine the height of tall objects. For this applied geometry lesson, students use common objects to construct a tangent height guide. They use principles of...

Pupils calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to measure...

Students shoot off a rocket and measure the trig ratios relation. In this geometry instructional activity, students practice using an inclinometer to figure out how high their rockets fly. They measure angles and height and relate it to...

Young scholars use hypsometers to measure tall objects.

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

In this angles of elevation and depression worksheet, 10th graders solve 6 word problems that include finding angles of elevation and depression. They solve each problem, rounding the measures of segments to the nearest hundredth and...

Middle schoolers explore the concept of the golden ratio in nature and architectural design. They discuss examples such as petals on a sunflower and the Parthenon. In small groups they take turns measuring their body parts to find a...

Students use graphs and plots to measure the basal area and stocking levels.  In this graphing instructional activity students work in the field the use their data to help them complete a lab activity. 

In this angles of elevation and depression instructional activity, 10th graders solve 4 word problems that are related to determining the angles of elevation and depression. First, they define angle of elevation and angle of depression...

Students apply their math and measuring skills to create "tree trunk" panels for their tropical rain forest. They use their recorded information to construct strips of paper that are correct height.

In this distance worksheet, students calculate the lengths of sides and diagonals of figures.  Students also compute lengths in shadow problems.  The solutions are provided by clicking on the "show answers" tab at the bottom of...

Learners, through lecture and guided practice, discover the properties of similar triangles. They use given measurements of one triangle to find a missing measurement of a similar triangle. They apply this knowledge in real-life...

First graders measure a plant using unifix cubes and record their measurements on a class chart.

Students use GPS and trees to explore lichens and air quality.
