Young scholars use tools in a painting package to design tiles and create repeating patterns. They design a single tile using a 4 x 4 grid and experiment with changing the alignment of some of the tiles by rotating different areas.

In this chemistry worksheet, students respond to several multiple choice questions relating to bonding and acid-bases. They also identify the various types of bases and how they differ from each other.

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

This is an interesting geometry problem. Given the figure, find the area of a triangle that is created by the intersecting lines. The solution requires one to use what he/she knows about coordinate geometry, as well as triangle...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Equip young campers with important survival knowledge with a set of engaging lessons. Teammates work together to complete three outdoor activities, which include building a shelter, starting a campfire, and finding directions in the...

Students engage in a lesson plan which reinforces the concepts of clockwise and anti-clockwise rotation, while developing an understanding that angles are measured in degrees. They utilize a mathematics educational program to gain practice.

Learners complete experiments as they act as the earth. They observe how different angles affect the phases of the moon seen by us. They discuss the differences in light and dark.

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

Students investigate the concept of tessellations and how they are formed using angles. They categorize how different patterns do and not tessellate and separate them into two different places for assessment. The teacher draws examples...

Ninth graders explore a variety of geometry and science concept while making an origami frog. The fold paper into the shape of a frog and conduct measurement activities including frog leaps.

Students discover that polarization filters block incoming light from passing through when filters are positioned perpendicularly to each other. They explore some of the uses of polarization filters within our society.

Sixth graders discover transformations. In this graphing lesson, 6th graders explore visual examples of plotting transformations as they review translations, rotations, and reflections. Students also practice solving problems that their...

Young scholars investigate triangles and their relationship to each other. In this geometry lesson, students solve right triangles using the properties of the Pythagorean Theorem. They differentiate between right, acute, straight and...

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

Taking the notion of symmetry to the next level, this looks at combining rotation and translation symmetry to build spiral symmetry in three dimensions. Using the Zome modeling system and an instructor’s guidance, geometers try to build...

Young scholars identify and apply properties of triangles. In this geometry instructional activity, students define equilateral triangles by sides and angles. They build cardboard triangles as they study properties of triangles.

View molecular structure for various compounds with three-dimensional color images. 

Learners examine a selection of shapes and identify which shapes tessellate and why. They design and make a pattern which involves translation, reflection, or rotation. Students describe the features of 2-dimensional and 3-dimensional...

High schoolers examine how the link between the tilt of the Earth's axis to the ecliptic and seasons of the year--length of day, effectiveness of sunlight, polar day and night, and seasons south and north of the equator, as well as near it.

Learners experiment with mirrors to explore the Laws of Reflection.  In this experimental lesson plan students develop their own experiments and follow a list of assigned steps then report what happens in their activity. 

For this matrix multiplication worksheet, students multiply matrices and identify the rotation matrix of a given angle. This two-page worksheet contains examples, explanations and two problems to solve.

In this trigonometry learning exercise, students solve and complete 5 various types of problems. First, they find the exact ratios for each trigonometric function. Then, students use the expansion to find the exact value of a given trig...

If both pairs of opposite sides of a quadrilateral are congruent, is the quadrilateral a parallelogram? This task asks learners to determine the answer and to support their answer with a proof. The resource includes a commentary for...
