Learners engage in a discussion about what a parachute is and how it works. They create a parachute using different materials that they think will work best. The students test their designs, which will be followed by a class discussion...

Learners discuss different types of sea turtles. They talk a about the characteristics of sea turtle anatomy. Students pretend to look over the edge of a boat in the ocean. They pretend to see a sea turtle. Learners create their artwork...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

Students become familiar with the style of architecture of medieval times.  In this architecture instructional activity, students design a model of a medieval castle including its cornerstone. Students understand scale in their...

Young scholars use pieces of farm pictures to investigate the elements of art.  For this farm art lesson, students use pieces of pictures to create an original artwork. Young scholars use the Internet to find images.  Students...

Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...

Scissors, glue, and an old book. Punches, crimpers, and rulers. Kids gather their tools and get set to create relief sculptures by deconstructing books.

Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...

Middle and high school students engage in enameling and apply design elements. They study the history and tradition of Cloisonne. The history of traditional Chinese Cloisonne dates back over 700 years, with the most beautiful, artistic...

Host an exciting lab in which learners burn fruit rinds to better understand hydrocarbons. A reading passage and analysis questions wrap up the lesson. 

Eighth graders explore the area of astronomy. They explore Earth's neighboring planets. Students research a planet's characteristics. They develop a scale model of the solar system and a narrative about the planets.

Get your spy glasses ready! In this weeklong adventure, children will explore shapes and their attributes and use this knowledge to decode a secret message. Children will learn about two-dimensional (flat) and three-dimensional (solid)...

In this video segment from Cyberchase, two friends make rock candy while learning about 2-D and 3-D shapes.

The students will make the connection between 2-D and 3-D shapes using modeling clay and geometric solids and participate in an interactive web lesson plan. Students will make predictions about what 2-D shape they think will be made when...

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them.

Learn about platonic solids, a special type of polyhedra. Read a definition, make three-dimensional models using printouts, and play with an interactive animation, which will show you the faces, vertices, and edges on platonic solids:...

"The volume of a cube can be developed by considering unit cubes, a single row (longs) of unit cubes or a single layer (flats) of cubes using this applet." This easy software makes it possible to easily construct a cube and take it...
