Middle schoolers compare and contrast the three primary types of bridges. In this technology lesson, students design and build a bridge that spans 25 cm. They test their design and present the results to class.

Middle schoolers investigate how engineers use different types of bridges for different places. In small groups they design and construct bridges for three different scenarios, and answer a series of investigating questions applied to...

Students examine how there are many elements that need to be considered before building a bridge. Groups are given materials and they are to make a structure that can hold an object in suspension.

This engineering activity gets youngsters working together to design and construct a bridge. Each bridge is tested in front of the class to discover how much weight it can hold before showing any change in form. The lesson plan does not...

Students build a model of a bridge and test the amount of weight it support. They identify different types of bridges: suspension, arch, girder, truss, cantilever, cable-stayed and moveable.

Students explore the forces of tension and compression by manipulating a variety of objects, and apply what they learned in the construction of a model bridge.

Students, in groups, design and test a scale bridge. They use the Internet to research three basic bridge designs -- beam, arch, and suspension -- and the forces that act upon them.

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...

Will that structure survive the force? The differentiated lesson plan allows pairs to choose the structure they would like to construct and the building materials they wish to use. Individuals record their findings in...

Students design and construct a suspension bridge. Math is used to compare the actual measurements of the bridge to the student's version.

Students investigate the process of constructing a bridge. They study the meaning of structural force and draw pictures of examples. Students identify the types of building materials have been used in history to construct bridges and how...

Students identify important structural elements in bridges. They use a worksheet and websites to investigate different types of bridges and variable factors that relate to building a bridge.

Students explore how to build a bridge and test how much weight it can support.

Knowing how to mix concrete is a big part of having a construction job. Here vocational learners will go through the types, economy, and uses for concrete. Each slide is rich in text but organized in an easy-to-read style. Images and...

Students examine the economic and ecological benefits of forest canopies. They read and discuss an article, answer questions, conduct research, draw field sketches of a canopy ecosystem, conduct a feasibility study, or prepare tourist...

Students take a field trip to Lynn Canyon. In this Temperate Forest lesson plan, students visit the Lynn Canyon. Students collect samples of leaves and water to take with them to study. Students view the samples under a microscope.

Students solve quadratic functions. In this solving quadratic functions lesson, students determine the height of an object at a given time. Students determine the time at which an object hits the ground. Students answer questions...

Fourth graders are shown how to read a map and identify key cities, landmarks, rivers, state boundaries, and train routes. They solve basic mathematical problems. Students reivew the componets of a map legend. They are asked to find...

High schoolers engage in a reading of "An Occurrence At Owl Creek" in order to work on the reading comprehension skills of prediction with looking at the ending. They predict the next events leading to the ending and summarize how it...

In this activity, you build and test two types of bridges: a simple suspension bridge and a beam bridge. Which bridge design is stronger?

Survey potential bridge sites, research bridge design, and select the right bridge for the right location in this interactive activity from the NOVA: "Super Bridge" Web site.

Find out the different strengths of two types of bridges, beam and suspension, by building your own. This Science Buddies science project gives you the means to find out. The Science Buddies project ideas are set up consistently...

Learn all about bridges in this interactive learning module.

Compare the strength and practical uses of beam bridges and suspension bridges. Investigate how the cable contributes to the stability and strength of a suspension bridge.
