If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...

A bit optional. How do computers transmit in the real world? Pupils research a device that is used in transmitting bits, then individuals create a poster that presents the information they have learned about their device. 

Can your class solve the Mystery of the Crooked Cell? Junior geneticists collaborate to learn about sickle cell anemia in a fascinating lesson plan. The included materials help them to examine the genetic factors behind the disease...

Scholars become experts on the moon, its phases, and craters with a series of lessons, activities, and extension opportunities. Learners' expert level of knowledge includes moon facts, how moon craters are created, the ability to...

What would be your class's ideal world 30 years in the future? What about 100 years? Use a series of activities to discuss globalization, sustainability, scientific contributions to society, and the global community of which your...

Construct tangent lines and make the connection to tangent functions. An informative lesson reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...

You sunk my battleship via the Internet? Groups of three play a modified game of Battleship using the Internet Simulator. Team members determine how to address messages, so each player knows who the message is for, and refine their text...

Use simulations to determine the probabilities of events to make decisions. Class members are presented with several scenarios, some with known probabilities and others without. Groups run simulations to gather data that they then...

Be 100 percent confident who has the most and by how much. Pupils use percentages to help make the comparisons by finding what percent one quantity is of the other. They also determine the percent differences between the two...

Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...

Do ratios have values? The seventh instructional activity in a series of 29 introduces the value of a ratio. Pupils create associated ratios to a given ratio. They also describe the fraction associated to the ratio as the value of the...

The 23rd segment in a series of 25 presents random samples from two populations to determine whether there is a difference. Groups determine whether they believe there is a difference between the two populations and later use an...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

Can my windmill pick up a weight? Given the same set of materials, groups design and build the most efficient windmill. On the first day, groups concentrate on getting a windmill to spin, while on the second day, they modify their...

Graph linear equations in standard form with one coefficient equal to zero. The lesson plan reviews graphing lines in standard form and moves to having y-coefficient zero. Pupils determine the orientation of the line and, through a...

The plot thickens to get a functional understanding. After a short review of plotting points on the coordinate plane, class members learn the difference between functions and relations in the second lesson in a series of nine. They...

The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

The truth is always best. Individuals continue to find values that make equations true in the 26th installment of the 36-part module. The only difference is that they now call them solutions to those equations.

How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

Find out if your class agrees with Ice Age: Continental Drift ... or if it's just a fun family movie! Class members research the theory of continental drift, examine evidence of plate tectonics, connect...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Here is a collection of activities that complements each of the five senses. Youngsters explore textures, sounds in song, food tastes and aromas, colors and patterns, and a variety of experiences that boost...

How fast is your class? Learners determine the amount of time it takes individuals to walk a given distance and calculate their speeds. Pupils solve distance, rate, and time problems using the formula and pay attention to the...

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson, pupils discover the relationship between multiplication and division. They develop the...
