It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The instructional activity connects geometry, earth science, and delicious snacks to teach kids...

Student scientists investigate triangle structures. In this building lesson plan, students explore how to design triangle braces in the construction of structures in order to build a stronger base.

In this angular size and similar triangles worksheet, students use the properties of similar triangles and the ratios of sides to solve for unknowns in given diagrams.

Young scholars explore what the Bermuda triangle is and the theories as to why it is so mysterious.  In this mystery lesson students read and discuss the history and the mystery behind the Bermuda Triangle. 

Students map magnetic fields of a magnet using a compass and predict where fields cancel each other to create 'Bermuda Triangles'. In this magnetism lesson, students use a compass to map the magnetic field of a magnet. They explain how...

A benthic habitat hosts a vast collection of organisms and its structure influences the biodiversity. Middle-school marine biology explorers will discuss how corals impact structure, and therefore diversity, on the ocean floor. They draw...

Introduce infectious diseases and the epidemiologic triangle. A helpful resource describes the agent, host, and environment from the three vertices as well as the time factor, which is in the middle. Scholars complete a simple...

High schoolers calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to...

Students examine the epidemiologic triangle. In this disease lesson, students discuss infectious disease as they study how they spread and discover their families' experiences with them. Students research Internet sites to complete...

Students estimate the area of states using the formulas for the areas of rectangles, squares, and triangles. In this geometric shapes lesson plan, students divide irregular shaped states into shapes. They use the formulas for areas of...

Students conduct an experiment.  In this fire lesson, students view an experiment where they learn the conditions needed to keep a fire burning.  Students discuss the experiment and learn about the fire triangle.

Does practice make perfect or just improvement? Scholars practice drawing a triangle on an Etch-A-Sketch. They learn about the part of the brain that controls sensory-motor integration and apply that to an analysis question.

In this refraction through a triangle worksheet, students use a given diagram of light striking a triangular piece of plexiglass to determine the light ray's angle of incidence, the ray's angle of refraction, they use Snell's Law to...

Students examine Pascal's Triangle and attempt construct it on their own.  In this visual patterns instructional activity students explore patterns that exist in Pascal's triangle.

Young learners view different shapes drawn by the teacher on the board. The teacher identifies each shape by name and discusses the importance of knowing the difference between shapes when building something. The pupils complete the...

In this shape lesson, learners cut out tangram shapes and create different pictures with them. They look at 3-D shapes as well. There is a nice, hands-on component built into this lesson.

The earth only revolves around one thing — and it's not any of your pupils. The instructional activity includes two activities dealing with the distance to the sun and the moon. First, scholars create a pin hole camera and use the rules...

Students observe teacher demonstration, discuss Fire Triangle, examine three things that fire needs to continue burning, including fuel, oxygen, and heat, and discuss how Stop, Drop, and Roll strategy is safest method of stopping...

Students construct equilateral triangles and a 'laser' triangle.  In this reflection lesson students build a retro-reflector using mirrors.

Students calculate the Fibonacci sequence of numbers. Through the use of Fibonacci numbers in flowers, leaves, fruits, vegetables, pine cones, and other forms of nature; students explore how Fibonacci numbers occur in nature. Then they...

Homes come in many different shapes and sizes. Building a model of a geodesic dome is the ultimate goal for the activity. Cutting and folding is the way to go here.

High schoolers explore how to use trigonometry in the aviation field.  In this aviation instructional activity students complete trigonometry equations that show what planes should do to land their airplanes.

How can we identify shapes in the Universe? High schoolers will compare and contrast elliptic and hyperbolic geometry. They will also explore one possible way to measure the curvature of the Universe, namely, by measuring the sum of the...

How does fire keep itself going? Explore the ways that heat uses fuel and energy with a lesson plan about the fire triangle and combustion. Several activities demonstrate how heat moves from warmer objects to cooler objects, as well as...
