Our teacher told us the formula had one-third, but why? Using manipulatives, classmates try to explain the volume formula for a pyramid. After constructing a cube with six congruent pyramids, pupils use scaling principles from...

Where is NASA going next with their rockets? A reading provides an overview of the next generation of rockets for space exploration. A full-page diagram gives the reader a scaled perspective of what this rocket may look like, for both...

What will it take to explore space? Teams of pupils determine the needs of a lunar outpost and research the required systems. The pupils then learn about the past space exploration vehicles. The third and final lesson challenges project...

You don't need a scale to determine weight. This activity provides a way to use the concepts of air pressure and surface area to determine the weight of a vehicle by calculating the amount of weight each tire supports.

Having more letters in your name helps you get a better grade in your math class—or does it? Learners create scatter plots to organize data. The lesson places emphasis on determining scale and intervals and labeling axis.

Continuing their study of beneficial insects, young entomologists discover where in the world some of these bugs are. By labeling, coloring, and using the scale on a map, pupils explore the territories and arrival of the Asian lady...

Three Dog Night isn't just the name of a band; it is also the way an Australian tribe, who used dogs to stay warm, would describe the temperature on a cool evening. After reading about many different ways of measuring temperature, the...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Knowing how to scale a recipe is an important skill. Young mathematicians determine the amount of ingredients they need to make a certain number of truffles when given a recipe. They determine a relationship between ingredients given a...

Explore relationships between perimeter and area. Learners compare the measurement units of gligs and crocs. They use a given perimeter and area as well as specific measurement relationships to determine the scale of gligs to crocs.

Develop a formula based upon numerical computations. The 31st part of a 33-part unit has the class determine the formula to convert a temperature in Celsius to a temperature in Fahrenheit. They do this by making comparisons between the...

Scholars develop the conversion formulas between Fahrenheit and Celsius with a task that presents the class with two known temperature equivalents between the two scales. Pupils use those two points to develop the linear conversion...

Friction leads to movement, heat, and melting on such a small scale most people don't notice. A short simulation permits scholars to observe the reaction between atoms as they move together.  The simulation applies the concept of...

Investigate the world of unknown quantities with a creative set of five lessons that provides problem situations for varying grade levels. Each problem presents a scenario of fruit with different weights and a balance scale. Using the...

Explore the meaning of scale and proportion with a set of five activities that examines the topic from elementary through high school. The first lessons explore ratio by examining pictures of different sizes. The next three activities...

Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

How bright are your classes? An interactive lesson has scholars explore how light interacts with carbon dioxide in the air and the surface of the earth. They watch a temperature scale as light interacts with the environment.

Does concentration affect the rate of a chemical reaction? Science scholars observe and control a chemical reaction in an interactive simulation. The resource allows pupils to add atoms to the reaction vessel and monitor the reaction's...

How do the products you use rate on a greeness scale? Scholars use a tool to analyze shampoos and cars for their sustainability. They consider factors that affect the environment, the economy, and equity. This is the ninth lesson in...

Model hardness testing with a self-designed hardness test. Young scholars rate the hardness of different types of aspirin using the Vicker's Hardness scale. They then relate hardness to the solubility of each aspirin tablet.

Explore different types of functions using an interactive lesson. Learners enter functions and view the accompanying graphs. They can choose to show key features or adjust the scale of the graph.

Large or small, bridges are architectural wonders! Construct a large-scale cable-stayed bridge during a whole class project. Scholars work in groups to erect the towers, build the roadway, and secure the cables of their very own bridges....

Get big results out of a small-scale lab! Young chemists observe the electrolysis of sodium sulfate using a microscale experiment. A colorful indicator solution combined with the production of gas bubbles yields a variety of observations...

Can you hear me from there? Pupils determine the place to build a cell tower on a hill. The class uses constraints and creates a scale drawing on a coordinate system to calculate the exact location of the base of the cell tower.
