Here is a collection of readings to be discussed in the science classroom. This one is in the form of a dialog between two boys in an amusement park, talking about the forces involved in a Graviton ride. Questions are listed at the...

In this geometry worksheet, learners describe the effect of a proportional change on the perimeter or circumference and area of the given circles or quadrilaterals.  The one page worksheet contains ten problems.  Answers are...

Practice identifying fractions with a worksheet that asks scholars to explore drawings and pinpoint parts of a whole. Class members asses figures and objects to identify the numerator, denominator, and write them in fraction form. 

Students identify tangents, chords and secants. In this geometry lesson, students graph circles and identify angles created by secant lines, tangent lines and chords.

Students explore uniform circular motion, and the relation of its frequency of N revolutions/sec with the peripheral velocity v and with the rotation period T, and the "centripetal acceleration" of an object.

Students measure the perimeter and area of their polygons. For this geometry lesson, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side lengths of triangles.

Sstudents explore and analyze the properties of geometric areas.  In this geometry lesson, sstudents use technology to simulate spinners and dartboards in order to fing areas of circles and sectors of circles and compare and...

In this geometry skills instructional activity, students examine 3 labeled circles and identify the noted items as diameters, chords, radii, or centers.

In this parts of a circle learning exercise, 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 area of sectors worksheet, students find the area of a given sector, area of inscribed figures, and area of shaded regions. This two-page worksheet contains 20 problems. An answer sheet is provided on the third page.

In this geometry worksheet, students draw an illustration of a circle centered between two points. They draw three line segments. Students answer two questions about the resulting angles. A sample, interactive drawing is included with...
