An excellent activity awaits your young scientists! In it, learners are invited to explore the world of pulleys, levers, and planes; simple machines that make lifting heavy things much, much easier. They watch video, and engage in...

Develop a sense of understanding. Pupils learn eight definitions dealing with types of lines and angles formed when two lines are crossed by another line. Learners use the definitions to identify the lines and pairs of angles in figures...

How do 2-D properties relate in 3-D? Lead the class in a discussion on how to draw and see relationships of lines and planes in three dimensions. The ability to see these relationships is critical to the further study of volume and...

Young scholars use an on-line worksheet to experiment with patterns of tessellations in regular polygons. As students observe different shapes in the "Tessellate" Activity they complete a data table and practice making predictions for...

As the green squares are removed, a little piece of the puzzle is revealed. What is it? A square, a triangle, a cow? Have your class guess their way to identifying five different plane shapes.

How many of 2-D or plane shapes can your class identify? Can they get them all? Little learners view and review the names of nine different shapes, such as rectangle, square, triangle, and circle, to name a few.

Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Students view a video about cost of materials. They work together to develop their own backpack taking note of the cost of materials. They create an advertisement to accompany their creation. They share their ideas with the class.

Fourth graders compare and contrast gliding flight and true flight. They investigate the basic principles of aeronautics. The class participates in activities to observe lift and the effect of air. Students design and fly their own...

Students consider the relationship between form and flight and investigate the history of man made flight and how wing shape and flexibility affects the maneuverability of an aircraft.

Students are introduced to lines, rays, line segments and planes and study the differences between them. They also practice graphing lines, rays, line segments and planes

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Students create their own airplane using straws and other materials and learn the principles of aerodynamics.

Provides an introduction to geometry with definitions of points, lines, planes and angles through the use of examples and a brief video lesson. [1:28]
