Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using...

If Earth is modeled by a grapefruit, what planet could be represented by a golf ball? This activity uses everyday and not-so-everyday objects to create a model of the Solar System.

Did you know that Pluto is smaller than the United States of America? It is difficult to conceptualize the size of planets and the distance between them, and the lesson addresses those exact issues. After a discussion, pupils create...

Students build and compare models of both an energy inefficient and efficient classroom. In this energy efficiency lesson, students creatively use recycled materials to build two separate classroom models. They factor in concepts such as...

Instructing blind or visually impaired learners means you need to make symbolic tactile representations of various processes to provide as much input as possible. But wouldn't it be even better to have your learners make the models...

Guided by their analysis of a scene, their initial sketches, and renderings, set designers begin to craft a scaled, 3-D model of the set of the play they have chosen. 

Take mathematics to the hoop! Pairs first measure the linear distances on a basketball court. Using those measurements, they determine the scale lengths to create a scaled model. To finish the activity, learners create models of the...

Kids compare what printed text looks like with the naked eye and under magnification. They discuss the extremely small scale that must be used to measure the size. They learn about the micrometer unit, then draw scale models of a variety...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Multiple representations of the varying theories of atomic structure. With these pictures and some background of the theories and scientific figures surrounding them, your class will develop a better understanding of scientific history...

Even light cannot leave the force of a black hole! Learners use a model to explore the gravitational force of a black hole. An elastic bandage and heavy ball serve to create the hole, while marbles become the victims of its strong force.

The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

What makes an effective fort, and why might a city feel that they need such a structure? Your young historians will explore the purpose and design for Fort McHenry, and build their own models of a fort based on the information they...

Young scientists learn how to select a scale factor for a large scale model. Then they figure the scale for each of the planets and the distance between them. Finally, they construct a giant scale model of the solar system and answer...

Students create a paper model to illustrate sea-floor spreading.

Junior geneticists construct models of DNA to discover sequencing and pairing of nucleotides. They use the models to simulate protein synthesis and then translate the codes into physical traits. Finally, they use the traits to create a...

Try your hand at scale models. Scholars create a scale model of an object using a scale factor of their choice. As part of the project, they give presentations on their processes and calculations. This is the last installment of the...

Geometry meets earth science as high schoolers investigate the cause and features of the four seasons. The effects of Earth's axis tilt features prominently, along with both the rotation of the earth about the axis and its orbit...

Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

Build a scale model of a home built out of shipping containers. A hands-on activity has scholars watch a video about a home built from shipping containers and then design their own home. They build scale models of their designed homes...

Students make several models of the solar system to learn the positions of the planets in the solar system as well as relative distances and sizes. Creation of these models will help them identify the planets by size, shape, color,...

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

The San Andreas fault is one of the longest fault zones in the world. In a series of 20 lessons, the fourth lesson has pupils use a paper model to recreate various types of plate faults. Each is held in position then drawn...
