Pupils examine a stress-strain diagram that compares the advantages and disadvantages of the two common bridge building materials, concrete and steel. The also consider the factors that influence the materials builders choose for their...

In this science worksheet, 4th graders answer multiple choice questions about coastlines, electric cars, the food chain, and more. Students complete 25 questions.

Steel is a man-made alloy or a mixture of metals. Lesson 18 in this series of 36 focuses on metals and their extraction from Earth. Individuals read about, discuss, and answer questions after learning how people find most metals, the...

See how a marshmallow can hold up a bridge load. Teams take a closer look at the design of bridge piers. They determine the types of loads that might affect a bridge, and, using that information, they calculate the needed cross-sectional...

Class members learn how to estimate the total costs involved to design and build a bridge by including design, material, equipment, and labor costs. The activity includes a discussion about the trade-off between cost and aesthetics.

For this science worksheet, students collaborate in performing an investigation regarding the best bridge construction for maximum strength. Kids build several designs of bridges out of pins, straws, fishing line, and small Styrofoam...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Teams use the design process to design, build, and test a model levee to protect the town from a wall of water. A handout provides a price list for the materials learners can use to build their levee within a budget.

Hold a discussion in your class about the increase in mercury being found in fish that are caught commercially as food for humans. Given a worksheet, learners then calculate how much fish a person can safely eat each month to remain...

In this bridge design worksheet, students answer 5 general questions about bridges. Students follow the directions to construct 4 types of bridges with paper and test them for strength.

It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep...
