Create bending joints—but don't break! The activity shows how to make a puppet using straws and fishing line. Pupils create cuts to make joints that rely on the elasticity of the straw to bend and return to their original shapes.

Let your class bounce to examine the concept elastic potential energy. Individuals bounce on a pogo stick in order to calculate its elastic potential energy. Groups then compare the elastic potential energy to the gravitational...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

Art and science sometimes go hand in hand. A set of four activities for learners in grades 3-5 teaches engineering concepts as part of art projects. Class members build homemade robots, elastic puppets, musical instruments, and...

Take a swing at a fun activity. Pupils first watch a video that introduces the concept of elasticity in association with tennis rackets. They then design their own rackets and build them out of available materials.

Harness the power of rubber bands of all things. A hands-on activity has scholars design and build paddle boats. They learn how the elastic potential energy of rubber bands can be converted to the kinetic energy associated with motion.

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

A little too much strain could cause a lot of stress. Groups conduct a strength test on clay. Using books as weights, pupils measure the compression of clay columns and calculate the associated strain and stress. Teams record their...

Mold your learners into materials engineers. Using glue, Borax, and water, scholars create a viscoelastic material. But your class might know it by another name—Silly Putty.

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

You'll bounce off the walls with glee after finding a fun resource. Young engineers design trampolines for golf balls. They build and test out their design and make improvements based on the results.

Today's gourmands don't consider spices to be the equivalent of silver and gold. During the middle ages, however, these commodities were precious. People back then used spices in religious ceremonies, to cure rotten food, and as a show...

Young geometers become pool sharks in this analysis of the angles and lengths of a trick shot. By using angles of incidence and reflection to develop similar triangles, learners plan the exact placement of balls to make the shot....

Wheeeee! Young thrill seekers build a bungee jump—not for themselves, though, but for an egg. The egg must fall from a height of five feet and rebound within two inches of the ground or floor.

Can you build it? Yes you can! This interactive game includes four design challenges presented on separate cards. The cards outline the challenges with limited restrictions but with an end goal in mind. The competitions include building...

Wind it up and let it go. Individuals build a basic spool racer in the second portion of a six-part unit on energy. After receiving three criteria, pupils modify their designs to meet the new challenge. Pairs compete against each other...

As an introduction to Steiner Trees, class members are challenged to find the shortest paths to connect multiple points. The teacher introduces the problem by showing how to connect three points. Groups then go outside and construct a...

Build vocabulary and get in the Halloween sprit with a collection of festive activities! Here, scholars take part in a holiday celebration, unearth the unknown in mystery feel-boxes, and create monster masks out of paper plates. 

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

Students add borax to a latex polymer and play with it to see the characteristics it now contains. In this polymer lesson plan, students see if it stretches, if it's durable, if the molecules break easily, and more.

This site discusses price elasticity, along with the formula for "arc elasticity," which is a different method to calculate price elasticity.

This site explains price elasticity of supply. Includes graphs to represent the concept.

This site provides a great definition of "price elasticity of demand," along with formulas and examples. It also shows a perfectly elastic demand curve and a perfectly inelastic demand curve.

This site offers a good description of price elasticity of demand for a good, and gives examples of which kinds of goods may be elastic or inelastic.
