Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

Elementary grade students investigate heat transfer in this activity to design and build a solar oven, then test its effectiveness using a temperature sensor. It blends the hands-on activity with digital graphing tools that allow kids to easily plot and share their data. Included in the package are illustrated procedures and extension activities. Note Requirements: This lesson requires a "VernierGo" temperature sensing device, available for ~ $40. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Consortium develops digital learning innovations for science, mathematics, and engineering.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.

Following Curiosity and Perseverance on Mars often means roving to places with interesting materials  to study, places away from the initial landing site. In this lesson, students experience the processes involved in engineering a communication protocol. To  reach their goal, students must create a calibrated solution within constraints and  parameters of communicating with a rover on Mars. Students will explore the opportunities and challenges of remote robotics by framing the problem around the idea that scientists and computer scientists must work together to successfully program rovers in remote locations like Mars. Students will also explore the idea that a robot simply follows a set of well defined algorithms.  Students will be provided a set of possible courses that their robot must navigate. Students will code their robot to navigate around the obstacles within the course to arrive at a set location.

Lesson length: 1-2 hoursGrade level: 6-8Students use a recipe to create bouncy balls and then measure the bounce of their ball to test damping qualities of different materials. Students practice using the scientific method and think about how engineers might use it.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

Lesson Length: 1-2 hoursGrade Level: 6-8Students learn about potential and kinetic energy as it relates to mountain roads. The activities are grounded in engineering design thinking as it relates to engineered roads and road repair. Also included is a challenge activity with renewable energy Snap Circuit simulations.This material is based upon work supported by the National Science Foundation under Grant No. 1657263.

This article links to resources to help teachers create their own weather stations, participate in real data projects, and assess their students' knowledge of weather tools.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.
