Explore the concept of measuring and recording circumference. In this physical science and measurement lesson, young learners blow up balloons, measure the circumference, and record the data on an interactive graphing website.

Sixth graders measure circumference and diameter to the nearest eighth of an inch, record measurements on a spreadsheet, and use the internet to complete a "scavenger hunt" of facts concerning pi.

Students review concepts of area and perimeter, find area and perimeter of circles, practice calculating circumferences with a calculator, and calculate area using pi button.

Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.

How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...

Students review the parts of a circle, calculate the circumference and area of a circle, and create student-made tests on the geometry of circles using educational software.

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

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

Using their knowledge of right triangles, pupils find out how far a ship is from a light house. Class members determine how far around the world a ship would be sailing at a constant speed.

Build an air lift siphon using your mad physics skills! Learners first investigate the importance of circulating water in aquaponics systems. They then use density to their advantage as they engineer an air lift siphon

Clamp onto the resource and don't let go. Future mechanical engineers produce a pipe clamp from a sheet of metal. This idea is to use the pipe clamp to affix a pull-up bar in a doorway.

Seventh graders use the Internet to research the holiday of Kwanzaa. Using the information, they create a brochure to promote the holiday to others. They email the information to a friend to end the lesson plan.

Fifth graders review EOG math terms and definitions found in their math notebooks, and pick between 15 and 20 words to put in a word search.

Students solidify their understanding of the terms "circumference" and "rotation" through the use of LEGO MINDSTORMS NXT robotics components. They measure the circumference of robot wheels to determine how far the robot can travel during...
