This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane, screw and pulley in the context of the construction of a pyramid, gaining insights into tools that have been used since ancient times and are still important today. Through numerous hands-on activities, students imagine themselves as ancient engineers building a pyramid. Student teams evaluate and select a construction site, design a pyramid, perform materials calculations, test a variety of cutting wedges on different materials, design a small-scale cart/lever transport system to convey building materials, experiment with the angle of inclination and pull force on an inclined plane, see how a pulley can change the direction of force, and learn the differences between fixed, movable and combined pulleys. While learning the steps of the

Students create models of objects of their choice, giving them skills and practice in techniques used by professionals. They make sketches as they build their objects. This activity facilitates a discussion on models and their usefulness.

Students apply what they have learned about the engineering design process to a real-life problem that affects them and/or their school. They choose a problem as a group, and then follow the engineering design process to come up with and test their design solution. This activity teaches students how to use the engineering design process while improving something in the school environment that matters to them. By performing each step of the design process, students can experience what it is like to be an engineer.

In this scenario-based activity, students design ways to either clean a water source or find a new water source, depending on given hypothetical family scenarios. They act as engineers to draw and write about what they could do to provide water to a community facing a water crisis. They also learn the basic steps of the engineering design process.

https://www.teachengineering.org/curricularunits/view/ucd_fieldday_unit

This unit provides the framework for conducting an “engineering design field day” that combines 6 hands-on engineering activities into a culminating school (or multi-school) competition. The activities are a mix of design and problem-solving projects inspired by real-world engineering challenges: kite making, sail cars, tall towers, strong towers and a ball and tools obstacle course. The assortment of events engage children who have varied interests and cover a range of disciplines such as aerospace, mechanical and civil engineering. An optional math test—for each of grades 1-6—is provided as an alternative activity to incorporate into the field day event. Of course, the 6 activities in this unit also are suitable to conduct as standalone activities that are unaffiliated with a big event.

Algorithms are one of the foundations of our technological world, and are driven by the scientists and engineers behind the scenes that write all of these different algorithms. This lesson is intended to get students interested in the inner workings of algorithms and the capabilities associated with them. We start by engaging students with very simple examples of algorithms which they can associate with. We then discuss Google’s PageRank algorithm for ranking the importance of websites based on the other websites that link to them, and play a fun game that can be used to find the same results as the PageRank algorithm.

Students are presented with the following challenge: their new school is under construction and the architect accidentally put the music room next to the library. Students need to design a room that will absorb the most amount of sound so that the music does not disturb the library. Students use a box as a proxy for the room need to create a design that will decrease the sound that is coming from the outside of the box. To evaluate this challenge, students use a speaker within the box and a decibel meter outside the box to measure the effectiveness of their design.

In this open-ended design activity, students use everyday materials—milk cartons, water bottles, pencils, straws, candy—to build small-scale transportation devices. They incorporate the use two simple machines—a wheel and axle, and a lever—into their designs. Student pairs choose their materials and engineer solutions suitable to convey pyramid-building materials (small blocks of clay). They race their carts/trucks, measuring distance, time and weight; and then calculate speed.

Students investigate how sound travels through string and air. First, they analyze the sound waves with a paper cup attached to a string. Then, they combine the string and cup with a partner to model a string telephone. Finally, they are given a design challenge to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the invention of the telephone has had on society.

Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two substances that typically do not mix, such as oil and water. This lesson and its associated activities are easily scalable for grades 3-12.
