Students explain that it is the tilt of earth's axis that causes the seasons. They engage in a variety of activities, both teacher-led and on the computer, which enable them to further explain how the Earth's axis affects the seasons.

Students use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

How much do you really know about our planet? Middle schoolers build up their prior knowledge about Earth, its placement in the solar system, its composition, and important geological vocabulary with an introductory earth science lesson...

In this trigonometry activity, students investigate the transformations that can occur to the basic trigonometric functions. The thirteen page activity contains explanation, examples, and forty-seven...

In this math worksheet, students examine how the moment of a force about a point is defined. They look at the 2 problems to define the information contained in them.

Students explore the concept of fractals. In this fractal lesson, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Students construct a tightrope setup, learn the basics of tightrope walking, and explain a little more about the physics behind balancing!

Fifth graders use pattern blocks and triagular grid paper to reivew shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked if they comprehend what a...

Students examine the different kinds of propellers and their functions.  In this airplane lesson students build a hand made propeller.

Students work in pairs, to make a square on the geoboards with a rubber band (or draw one on the dot paper). It can be any size and in any location and share their answers with the class.

Third graders investigate symmetry by reflecting objects in different angles. In this geometrical transformation lesson, 3rd graders define the terms translation, rotation and reflection in order to physically turn geometric...

Students create tessellations. In this geometry lesson, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.

Students create an art piece incorporating tessellating shapes, translational symmetry, reflectional symmetry,and or rotational symmetry. They are asked if they know the definition of tessellation. If so, students are asked what shapes...

Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.

In this science-related activity, students explore and experiment all the sides and views of an infinitely long cylinder with their eyes opened and then closed as they answer twenty four questions.

Students examine tessellations and their geometric properties. Students explore the concept of tessellations and lines, planes, angles, and polygons. Students experiment with the area and perimeter of polygons. Students analyze...

Students communicate and work in team fashion on defense. They use correct rotations on defense against a fast break or undermanned situation. In addition, they practice footwork drills, triangle shifts and "Three on Two" drills to...

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Students research and describe how currents are formed. In groups, they relate specific terms to the formation of currents and locate different currents on a world map. They also examine tides, how they are formed and how they are...

Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.

Students engage in a study looking for the differences found during the cycle of one lunar month. They conduct research using a variety of resources. Then the information is used to construct a lunar calendar to observe daily changes and...

In this linear transformation worksheet, students find a series of linear transformations and sketch them. This four-page worksheet contains approximately six problems.

In this transformation worksheet, students identify a series of transformations and sketch them. They use inversion mapping to establish a one-to-one correspondence between nonzero points. This four-page worksheet contains...
