Students design and build truss bridges, then test the strength of the bridge by attaching a scale. Truss armor is made of a simple craft stick and cube construction, but includes a handle near one end. This allows the user to grasp the structure from within and wear it like armor.

Another alternative is the house frame. Although it does not rely heavily upon trusses for its sturdiness, it does show the basic idea of what timber looks like within the frame of real houses. You can find the wood cubes used in these ideas here. Question 2 years ago on Introduction. It looks like you had a class set of hot glue guns with, what 9 year olds? How did you manage that safely? Answer 2 years ago. Here's how I support safe glue gun use: First, buy glue guns with an insulated tip and use only 10 watts.

Introduce how it works. Point out the parts that get hot the tip and the freshly melted glue. Demo how to use it always put glue on the bigger of the two objects being glued together, keep hands clear, wait seconds to dry. Explain how to handle burns put burn under cold water immediately for as long as it hurts. When not using glue guns, keep them out in front of you. I like to draw simple houses on cardboard and tell kids to keep the glue guns in their house when resting.

This thing is EPIC. I spent about an hour and it could actually support my weight, and I weigh pounds!

Tower Bridge in Sacramento, CA. Structural engineering is one of the oldest engineering disciplines. Through this classic introduction to engineering activity, students gain an understanding of some of the challenges faced by engineers whose designs must protect public safety, such as bridges like the Golden Gate Bridge that thousands of people depend upon every day.

Students experience the engineering design process to achieve effective designs, creating and testing prototype bridges to failure.

Triangle Truss Bridges

They also experience the use of scale models in engineering to study how the forces and loads acting on bridges or any structures can result in damage. Also like real-world engineers, students analyze their bridge designs by calculating strength-to-weight ratios as a measure of structural efficiency.

Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards. In the ASN, standards are hierarchically structured: first by source; e.

By engaging in the science and engineering practices of defining problems, developing and using models and designing solutions, students make sense of the engineering design behind bridges.

Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. View aligned curriculum. Students are presented with a brief history of bridges as they learn about the three main bridge types: beam, arch and suspension.

They are introduced to two natural forces — tension and compression — common to all bridges and structures. Students learn about the types of possible loads, how to calculate ultimate load combinations, and investigate the different sizes for the beams girders and columns piers of simple bridge design.

Additionally, they learn the steps that engineers use to design bridges. Deliver the activity introduction as a mission assignment, similar to how it is done in the Mission Impossible television series and movies. Be ready to show class some photographs of collapsed bridges from around the world, such as the four provided in Broken Bridge Photos Visual Aid.Join us as we come together to encourage, engage and empower each other in a shared learning experience. This week is Engineers Week, the perfect time for math and science teachers to hug-it-out and work together to get students excited about engineering.

But how, you say? Well, what goes left to right and looks like a straight line? Linear relationships, of course! And, whether they know it or not, this is a concept that students definitely see in both their math and science classes. As a math teacher, your closet is full of things only you think are fun — protractors, compasses, and stacks of graph paper. Science teachers get all the good stuff: funny-looking glassware, vented goggles, lab coats. But what you want to keep an eye out for are sensors and data collecting devices.

In the case of our project here, you will need: your very own TI graphing calculatora Vernier force sensor20 washers, string we used fishing linea small screw eye, and a popsicle stick. Grab a lab coat while your there — you never know! Tip 2: Folding paper is hard. I know you can already hear the whining and the list of questions. The answers are: yes, a strong bridge; and yes, using only paper.

This is a time to get creative and for students to learn some basics of engineering. Feel free to keep that tidbit of information to yourself until you feel like the kids have grappled with this problem long enough. Tip 3: Science is perfect. Lab equipment is not. In our tests, the washers we used exerted almost the same amount of force as the noise level on the force sensor.

The noise will be accounted when you run the regression. That noise will show up as a y-intercept in your regression equation. Now you know why. You can breathe now.

Tip 4: Gravity is a harsh mistress. Want some math that will blow your mind? This crazy thing happened as we wrote this lesson — we discovered gravity.Who plans, designs, and builds bridges? Some of our community helpers do! Civil Engineers plan and design bridges for our construction crews to build. These important community helpers get us where we need to go, especially if we have to cross large bodies of water like rivers.

This bridge building activity is a great engineering project for kids. It starts with the planning and designing process and ends with the building process. Design and engineering are parts of STEM which stands for science, technology, engineering, and math.

STEM is a big part of the world around us and is definitely used in building bridges!

Building Bridges Engineering Activity

An engineer must take into consideration many things when planning a bridge or even fixing an old bridge. We started our bridge building activity by taking a look at different styles of bridges on our iPad. We also discussed how strong our bridge should be. Will it be for cars or just people? We also talked about the landscape around the bridge. He decided it was rocky. The next step was to use paper and pencil to develop a design for our new bridge.

I had pre-drawn samples of water for him to use, and he colored and designed his bridge. Next we moved on to the building stage. I cut out several bodies of water from blue construction paper to use for building bridges. With a set body of water, he could build the bridge accordingly. He decided to put two bodies of water together. He used most of our materials to make his bridge.Trigonometry is one of the basic math classes that you typically take in high school, and you also need it as a core course for almost any bachelor's degree.

It involves studying and calculating angles in three dimensions. Construction workers utilize trigonometry extensively in order to calculate the best way to build projects that are stable and safe. When construction workers lay the foundation for a house, they rely heavily on trigonometry to make sure that the foundation is level and stable.

Because the ground is usually sloped and uneven, contractors must use trigonometry to determine the angles and volumes needed to cut and fill areas of the ground in order to make it level. Things get even more complicated if the house requires an irregular foundation to accommodate curved hallways or walls. In a bridge construction project, trigonometry is essential for determining just how long a bridge needs to be. A contractor might use right angle properties and tangents to determine how wide a river is, which directly determines the length of a bridge.

For example, if he's standing on the river's edge, 10 feet away from where the bridge will be, then all he needs is to measure the angle from where he's standing to where the bridge will stop on the other side of the river.

He can then use the properties of a right triangle to calculate the rest. The angle of trusses, which provide support for holding up roofs, and the length of rafters in the roof are determined using trigonometry. For example, in a triangular-shaped roof, if you already know the length of the rafters and the horizontal length of the roof, you can use the law of cosines to determine at what angle the trusses should be cut for maximum support.

If you know the height of the roof and its horizontal length, you can also use trigonometry to determine how long the rafters should be.

A simple example of trigonometry's use in construction is in the building of wheelchair ramps. For example, if a ramp has to be at an angle of six degrees for maximum safety, and you know how high the exit is from the ground, you can calculate the wheelchair ramp's necessary length using a simple tangent ratio from a right triangle.

This one is second best, but it carried the most weight. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. I thought it would be fun to do a bridge building challenge to go along with our study of bridges. I found this idea […]. This site provides a wealth of technology information sheets for pupils and teachers. This was a week of challenges for us.

Last Friday at CC there was a project introduced for the students to build bridges made from straws, rubber bands, and play dough, as part of our physics portion of Cycle 2. The bridges had to be built in class and will be tested at the end of the term to see if they hold weight. The bridge that holds the most weight "wins.
