Straw Bridges

Have them tell the class how many books their structures were able to hold and describe the failure mode of their designs. Cut the tape only when the entire perimeter of the shape is covered. You need drinking straws and blue tac. Re-Design Practice: Have the students list any design or fabrication changes they would make to the structures. I call out the name of a shape and the students will draw the shape on their white board. Post-Activity Assessment Re-Engineering: Ask students how they might improve their bridge designs, and have them sketch or test their ideas. With the Students Figure 6.

There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. They perform an activity to develop and understand problem solving with an emphasis on learning from history. I then demonstrate how to build a triangle using pipe cleaners and straws. The book points out some of the many frequent places where 2D shapes can be found. Today you all are going to be engineers with a specific problem: you must build a structure to hold up as many books as possible using only the materials provided.

When we test your bridge, pennies will be added to the cup until the bridge collapses. Help children describe the differences. Materials Needed: building blocks, or sets of geometric solids two 30 — inch strands of yam Anticipatory Set: Allow children to pick out several shapes from tubs of geometric shapes. Use your finger, use your finger, Make it round as a pie.

Have them cut out the pictures and glue them onto a page with that shape drawn on it. Example straw bridge design Howe-Kingpost placed on the wooden support structure for strength testing. If only flexible type straws are available, cut off the straw ends that contain the flexible sections. Or turn a simple cube into a house by adding a pyramid on top and covering the sides with decorated paper? Oval Activities and Crafts Easter is an egg-cellent time to talk about ovals. The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values; by the findings of scientific research; and by differences in such factors as climate, natural resources, and economic conditions.

They also find out about the material properties important to bridge construction and consider the advantages and disadvantages of steel and concrete as common bridge-building materials. In their first attempts to build the structures, they build whatever comes to mind. Students will then be able to make the connection that the name of the shape is actually referring to the number of sides of the shape. Make a large 2 piece Venn Diagram 7. Triangle Activities and Games What you need: Triangle patterns Construction paper Scissors What you do: Print triangle patterns on heavy printing paper, laminate for extra strength if desired, and cut out. If part of a structure is carrying more weight than the rest, the structure will most likely fail faster and not be able to hold as much as when the structure is loaded evenly. Use finger to draw circle in the air.

If time allows, give the group the opportunity to build one last design after they understand the concepts. What makes a bridge a beam bridge? Make a circle, make a circle, Draw it in the sky. Ask students to predict whether this shape will roll or like down the incline on the face I have pointed to. Although iron and wood are not used as much today in modern bridges, the Howe Truss pattern is still widely used. Continue this process until the desired number of sticks are connected, then close the shape by connecting the ends together. The Parthenon was a temple built to represent the power and strength of the residents of Athens, Greece. To design an improved process.

With very little force applied, the empty square shape twists, while the square shape composed of inner triangles withstands much more force. In 2003, the tallest building in the world, the Taipei 101, was completed see Figure 1. Answer: Take the average height of the class and divide into 1671 to see how many students it would take to reach 1,671 feet tall. Show them how a square deforms under pressure whereas a triangle does not. Engineers always consider the design objective when creating models. To design a new product. Again, provide 1 minute to discuss ideas, 8 minutes to build, and 2 minutes to test.

The design of bridges is important to the transportation networks we depend upon. Have them consider buildings and structures they see in their everyday life. However, the city does not want the bridge to affect the fish population in the river below it. Skip to the shape my darling. Explain we will be investigating these solids by constructing a slide and then doing an experiment.

Discuss with students similarities and differences between the shape. As each group presents, a list compiled a list of their ideas, which the class may review once the presentations are finished. Blue represents the water below the bridge. That group should select a member to go up to the class board every round should have a different student go up so everyone participates. If you see students who are not pinching a straw before inserting a stick, remind them of the dangers and supervise them as they properly connect the sticks at least one time. As a class, discuss how learning from history and knowing more about the strength of shapes helped them build improved structures the second time. The rest of the class should identify this shape.

With very little force applied, the open square shape twists, while the square shape composed of inner triangles withstands much more force. Circle Activities and Rhymes Circle Rhyme Circle, a circle, Draw it round and fat. If they get it right, they get a point. I discuss the prefixes of each shape name and how it relates the number of sides. I like to use this book to begin this lesson because it discusses the number of sides for the various plane shapes.
