An excellent lesson 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 hands-on...

Students 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...

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...

Learners 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.
