Very simply, pairs of learners construct a model of the tetrahedral silica structure using raisins and toothpicks. They dip it into a soapy solution and then blow a bubble "atom" into its center. The lesson plan gives instructions that...

In this geometry lesson, 10th graders fold a dollar bill to make a tetrahedron. They analyze geometric shapes and apply it hands on.

Let's go fly a kite! Discuss the concept of two-dimensional and three-dimensional objects with your math class. They examine a triangle and discuss the face, vertices, edges, and angles. Then they build their own Tetrahedral Kites and...

Ninth graders investigate the concept of a tetrahedron and how it is formed with its congruent faces. They practice making the shape by practicing the folding paper to create the shape. Students continue the lesson with the estimation...

In this 3-D objects and common solids worksheet, students cut out and count the number of faces on several different types of boxes and make a cuboid from straws or a card. Students fill out 4 different categories involving 5 different...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

This resource offers a series of hands-on activities in which learners sketch and construct symmetrical origami, paper dolls, snowflakes, and polyhedra while adhering to specific requirements. These activities ask class members to...

Everyone loves a lesson that involves throwing things around! To understand probability, your experimenters will predict how different cylinder-shaped objects will land when tossed. When the data is collected, they will calculate the...

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

Using a game format, learners review what they know about theoretical probability. As they roll tetrahedron dice, they record their results as odd or even. Afterwards, they discuss their findings.

Brilliant graphics depict a variety of allotropes, especially the allotropes of carbon. Some notes are available to help make these useful for teaching your young chemists, but not for every slide. With some additional preparation on...

Students learn through bubbles. In this science lesson plan, students test the effect of four differently shape wands and three geometric figures in a bubble mixture.

Students investigate the effects of four different shaped wands and geometric shapes in a bubble solution. In this bubbleology lesson, the students build water and soap molecules. Students work in cooperative groups and conduct...

Students explore the concept of minerals. In this minerals lesson, students discuss how cooling affects the size of crystals. Students discuss how the structure of minerals is a tetrahedron. Students discuss the structure of silicates...

Students sketch the shape of three dimensional pyramids using nets. In this geometry instructional activity, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...

Sixth graders compare and contrast two-dimensional shapes to three-dimensional shapes. After watching a demonstration, they make their own shapes using nets printed on paper. To end the lesson, they use the shapes they made and...

Students construct a pathfinder that could land an egg safely. In this physics lesson, students explain the factors affecting the dynamics of falling objects. They evaluate their pathfinder design.

Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Learners construct an origami models of different molecules. In this chemistry lesson, students explain what expansive soils are made up of. They discuss what happens when this expansive soil expands or shrinks.

In this math worksheet, students are asked to read the book that focuses upon the creation and explanation of three dimensional shapes.

This website provides instructions on how to create a truncated tetrahedron.

Drawings and discussion on the properties of the cube, with lots of links to related pages. With this page you can find how to make a cube out of tetrahedron. [Requires Java.]
