Students describe in words and graphic displays the elevation or depression profile of sections of Mars' Olympus Mons and/or Valles Marineris. They explain how orbiting spacecraft build up global maps one data slice at a time.

Students explore Green Construction. For this lesson based on the experiences of Peace Corps volunteers, students gain insight into alternative construction in Guatemala. They examine the pros and cons of using alternative building...

Learners observe how to measure in metric units.  In this investigative lesson students compare different units of volume to see how things are measured.

Students construct the formula for the area of a rectangle.

Unfortunately for young mathematicians, the world isn't made entirely of parallelograms, triangles, and trapezoids. After first learning the area formulas for these common shapes, students apply this new knowledge to...

Pupils calculate the stride length of a walking or running animal. They use scale models of dinosaurs to calculate the leg and stride length of the animals.

Second graders, using one inch grid paper, create a foot long and a yard measuring tool.

In this measuring lengths worksheet, students determine which units to use when measuring lengths, estimating lengths, and the errors made when measuring, Students estimate the lengths of each of the lines illustrate to the nearest unit....

Students measure the length, width and height of different materials.  In this design lesson students complete a lab to see what engineers need to consider when planning a structure.

Learners investigate measuring angles correctly through projectiles. In this geometry lesson, students launch a projectile to investigate the importance of how to measure an angle correctly and to explore trajectory. They collect...

In this perimeter and area worksheet, 9th graders solve 17 various types of problems, mostly word problems related to determining the area or perimeter of a geometric shape. They also determine the area and perimeter of shaded portions...

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

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

In this area and volume worksheet, students find the lateral area, total area, and volume of given prisms. This two-page worksheet contains six multi-step problems. Answers to each problem are provided on page two.

Students define the laws of sine as it relates to a right triangle. In this trigonometry lesson, students identify the properties of sine to help then find mixing sides of a right triangle. They also solve for the missing angles.

Learners construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.

In this polygon area worksheet, students answer 8 questions involving the area of several polygons. Students are given various details of the polygon and must find lengths of various polygons.

In this lunar boulders worksheet, students use an image taken by the LRO satellite of the surface of the moon to find the scale of the image and determine the number of boulders and their approximate sizes.

Students explore proportional reasoning.  For this middle school mathematics lesson students investigate scale drawings as they create a proportional representation for the carvings on Mt. Rushmore.

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 solve problems using various strategies. In this problem solving lesson, students read the book Swimmy by Leo Lionni. Students make fish swimming patterns, measure how many goldfish crackers it takes to make a handprint and...

In this right triangles worksheet, students use trigonometric ratios to determine the length of a side of a triangle or a missing angle measurement.  This two-page worksheet contains 20 problems.
