Students discover electrical resistance and how it is directly related to thermal energy through a hands-on activity. Working in groups, they wrap a wire around a thermometer and the positive and negative poles of a D cell battery and...

Young scholars construct ratios using the hand as data. They use examples of cortical and trabecular bone found in the long bones to measure circumference, diameter, length, and weight of long bones. They perform computations using...

Students complete multi-curricular activities in a Halloween themed lesson. In this Halloween lesson, students examine newspaper ads to find prices of pumpkins and use them to complete a stem and leaf plot. Students find the diameter,...

Fifth graders diagram and label the parts of a tree. For this lesson on how trees obtain food, 5th graders diagram and label the parts of a tree, and determine the diameter, height, and age of a tree.

In this circumference worksheet, students find circumference. Radius and diameter are given, as well as an answer key. Workspace is provided.

In this circle worksheet, students identify center, radius and diameter of three circles. An answer key is included on page 2.

Learners identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Here is a fantastic, educational handout packed with information and facts not only about the planets in our solar system, but also regarding major moons and their surface features, dwarf planets, comets, and asteroids. 

Learners identify the relationship between the radius and Pi. In this geometry lesson, students calculate the circumference and area of a circle. They create visuals to help them see how the circumference relates to Pi.

In this inscribed angles and arcs worksheet, 10th graders solve and complete 21 various types of problems. First, they find the measure of each inscribed angle. Then, students find the measure of each angle or arc in a circle with the...

For this estimation worksheet, students analyze a table with the diameter of four coins in fractional inches. Students solve 5 multiple choice problems in which estimating is used with fractions.

In this parts of a circle instructional activity, students place the names of 6 different parts of a circle in rectangular place holders. They use labels such as cord, secant, diameter, radius, tangent, and center.

In this measurement worksheet, 6th graders find the area, perimeter, radius, diameter and circumference of many different shapes. Students complete 15 problems.

In this discovering Pi worksheet, students read about finding Pi, then find diameter and circumference of circles. Text page numbers are referenced, but no text name is given.

Middle schoolers complete a lab in order to discover if the length of a viewing tube, its diameter, or the distance from an object affect the type of data collected and the resulting graph.

Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and...

Tenth graders investigate the circumference and diameter of a circle. In this geometry lesson plan, 10th graders relate circumference to diameter. They create a scatter plot to estimate the value of pi.

Students discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."

In this geometry instructional activity, students identify radii, diameters, chords, tangents, secants and other terminology associated with circles.  The one page instructional activity contains eighteen problems.  Answers are...

Pupils 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.

Students measure the circumference of an object to the nearest millimeter. They also measure the diameter. The relationship of the two measurements is taught and how the value of pi came into existence.

Students compare the size and shape of tubes that can be measured, to the size and shape of "nanowhiskers" that are too small to see. They practice measuring, calculating and graphing the ratio of circumference to diameter of a circle,...

In this science card learning exercise, students cut out the different cards and study the planets Earth, Venus, Mercury, Saturn, Jupiter, Mars, Pluto, Neptune, and Uranus. Students' objective is to learn each planets' orbit, rotation,...

Students explain the advantages of nanotechnology. In this chemistry lesson, students investigate pretzels' average diameter and circumference. They graph their result and compare with other groups.
