The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges. 

Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the...

Students explore bridges.  In this bridge lesson, students design and build a suspension bridge after visiting related websites and reviewing famous bridges in non-fiction books.  Students follow the instructions from the...

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

A few class periods will be required to complete this physics investigation with your high schoolers. There is an unavailable video written into the lesson plan, but there is plenty of material here to bridge the gap. Two terrific...

Students research bridges from around the world looking for the Parisian architecture. They identify arch, suspension, cable and covered bridges. They draw half a bridge utilizing Crayola Erasable Markers. They construct their bridge...

Students create a model bridge using steel. In this bridges lesson plan, students study John Augustus Roebling and how he created bridges out of steel and the impact it had on society. Then students build their own bridge model.

Young scholars explain how significant bridges are in our lives. In this technology lesson, students research the history and characteristics of their assigned bridge and draw it on butcher block paper. They write a short tour...

In this comprehension worksheet, students read and respond to five multiple choice questions about the story. Then they explain in a short answer response why there were people who opposed to the building of the Golden Gate Bridge and why.

In this comprehension learning exercise, students read a story and answer the six multiple choice questions that follow. They identify the longest bridge in the world, what happened during construction, and what possible dangers to the...

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.

Students identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.

Young scholars classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.

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...

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 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.

Students design a bridge. For this science lesson, students research different types of bridges and create a bridge using marshmallows, toothpicks and construction paper.

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.

Students make different variations of file card bridges and predict how much weight it will hold. In this file card bridges lesson plan, students put file cards between books in different ways and predict how many pennies it will hold.

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

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

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 investigate the corrosion of different materials in the lab. In this chemistry instructional activity, students construct a bridge considering different bridge designs. At the end of the instructional activity, they play the...

Students investigate and record data about sedimentation rates. They make a sedimentation bottle using aquarium gravel, sand and potting soil. They discuss the sedimentation rates that they see in their bottles.
