Pupils examine the Magnus effect and its history.  In this forces lesson students investigate the lift of a rotating cylinder.      

Fourth graders participate in a length and measurement tug-of-war game. They try and pull the rope as many feet as the teacher has marked, calling out their measurement when one side has succeeded.

Students determine that moving charges create a magnetic field. They discover that the speed and direction of motion, the amount of charge, and the deflection angle observed are closely linked. A voltmeter, pendulum, and a constructed...

Young scholars study the bottom structure of underwater habitats and how they can be mapped.

Pupils will determine distances to nearby stars using parallax. In this Astronomy lesson plan, students will use a web program, trigonometry, and sketches to determine the distance of stars.

In this activity, students will make a gauge to track wind direction.

In this math worksheet, students look for the words that are related to the math words used in the practice of geometry. They also practice spelling.

Students explore the concept of polygon properties. In this polygon properties lesson, students draw polygons with different numbers of sides such as pentagons, octagons, hexagons, etc. Students identify different geometric shapes in the...

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."

Fourth graders use computer drawing tools to create a house of geometric shapes.

Learners examine a math worksheet and determine how to divide a single triangle into four of equal area. Using geometric principles, they sketch two additional ways to divide into into four equal triangles. To conclude, students...

In this frequency worksheet, students use the standard rules for Scrabble to find the abbreviations used on the board. Then, the determine the frequency as stated in the chart shown to represent the correct number of letter tiles.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Students examine a powerful tool that can be used in the study of motion. They use VideoPoint to measure an aspect of an organism's motion: speed, acceleration, center of mass.

Students are introduced to the concept of aerial perspective and scale. Students will use satellite technology to view their neighborhoods and sketch the area surrounding their schools. They will take part in a neighborhood walk to view...

Recognize parallel and perpendicular lines in geometric figures and pictures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Explains the basic concept of perpendicular lines with step-by-step instructions and methods for solving specific problems on your own relating to this topic.

[Free Registration/Login may be required to access all resource tools.] This concept teaches students about perpendicular lines in the coordinate plane, and how to use slopes to determine whether or not two lines are perpendicular.

[Free Registration/Login may be required to access all resource tools.] Students practice identifying parallel and perpendicular lines after watching a video tutorial.

[Free Registration/Login may be required to access all resource tools.] This lesson covers determining if two lines are parallel, perpendicular, or neither and finding the equation of perpendicular lines to a given line.

Practice drawing parallel and perpendicular lines, line segments, and ray. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Students watch a video and attempt practice problems on how to count perpendicular lines in a drawing.

[Free Registration/Login may be required to access all resource tools.] Learn how to recognize and write equations of perpendicular lines.
