Music - Santo_Rico

Students work within constraints to construct model trusses and then test them to failure as a way to evaluate the relative strength of different truss configurations and construction styles. Each student group uses Popsicle sticks and hot glue to build a different truss configuration from a provided diagram of truss styles. Within each group, each student builds two exact copies of the team's truss configuration using his/her own construction method, one of which is tested under shear conditions and the other tested under compression conditions. Results are compiled and reviewed as a class to analyze the strength of different types of shapes and construction methods under the two types of loads. Students make and review predictions, and normalize strengths. Teams give brief presentations to recap their decisions, results and analysis.

Music - Daily_Beetle by Kevin MacLeod

For this maker challenge, students become biomedical engineers who design, create, and test a medical device that measures a patient’s pulse using a microcontroller, LED, and light sensor. Students use data collected from the device they build to determine how to best visualize the results, so that a doctor can view the patient’s pulse on the computer screen. During the challenge, students learn about basic coding, the capabilities of microcontrollers, how sensors gather data, how the human circulatory system works, and how to plot real data. Finally, students are challenged to make their systems portable so that they create wearable health technology. This is a great project for a high school senior design team project.

Music: Komputo - Francis Preve

In the culminating activity of the unit, students explore and apply their knowledge of forces, friction, acceleration and gravity in a two-part experiment. First, student groups measure the average acceleration of a textbook pulled along a table by varying weights (with optional extensions, such as with the addition of a pulley or an inclined plane). Then, with a simple modification to the same experimental setup, teams test different surfaces for the effects of friction, graphing and analyzing their results. Students also consider the real-world applications for high- and low-friction surfaces for different situations and purposes, seeing how forces play a role in engineering design and material choices.

Music - Brightly Fancy Oddities

Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By modifying the bottom surface of the cup, students find out what kinds of surfaces generate more or less friction.

Music: Deep Hat - Vibe Tracks

The engineers at Splash Engineering (the students) have been commissioned by Thirsty County to conduct a study of evaporation and transpiration in their region. During one week, students observe and measure (by weight) the ongoing evaporation of water in pans set up with different variables, and then assess what factors may affect evaporation. Variables include adding to the water an amount of soil and an amount of soil with growing plants.

Towers have been a part of developed society for centuries, serving a variety of purposes, from watch towers to modern cell towers. In this activity, student groups design and build three types of towers (guyed or cable-supported, free-standing or self-standing, and monopole), engineering them to meet the requirements that they hold an egg one foot high for 15 seconds.

Music: Bubblegum Ballgame - JR Tundra

Students are introduced to the futuristic concept of the moon as a place people can inhabit. They brainstorm what people would need to live on the moon and then design a fantastic Moon colony and decide how to power it. Students use the engineering design process, which includes researching various types of energy sources and evaluating which would be best for their moon colonies.

Students use a small quantity of modeling clay to make boats that float in a tub of water. The object is to build boats that hold as much weight as possible without sinking. In the process of designing and testing their prototype creations, students discover some of the basic principles of boat design, gain first-hand experience with concepts such as buoyancy and density, and experience the steps of the engineering design process.

Students are introduced to the distinctive properties of mixtures and solutions. A class demonstration led by the teachers gives students the opportunity to compare and contrast the physical characteristics of a few simple mixtures and solutions. They discuss the separation of mixtures and solutions back into their original components as well as different engineering applications of mixtures and solutions.

Students make a proportional model of blood out of red gelatin, a plastic bag, and rice. They learn about the different components that make up blood and investigate what happens when the arteries and veins experience buildup from cholesterol. They will then work in pairs to brainstorm ways to clean our clogged arteries.

Music- Sunday Spirit

Posed with a paradigmatic engineering problem, students consider and explore mathematical algorithms and/or geometric concepts to devise possible solutions. The problem: How should a robotic vacuum move in order to best clean a floor of unknown shape and dimensions? They grapple with what could be a complex problem by brainstorming ideas, presenting the best idea for a solution and analyzing all presented solutions, and then are introduced to an elegant solution. Rather than elaborately calculating the most efficient route and keeping track of which tiles the robot has visited, a random number generator determines which direction the robot will take when it hits a barrier. Students are able to visually confirm how an unfamiliar programming concept (a random number generator) can make for a simple and efficient program that causes an EV3 robot (that is suitably equipped) to clean a bare floor. Then students think of other uses for random numbers.

Students create their own anemometers—instruments for measuring wind speed. They see how an anemometer measures wind speed by taking measurements at various school locations. They also learn about different types of anemometers, real-world applications, and how wind speed information helps engineers decide where to place wind turbines.

Given an assortment of unknown metals to identify, student pairs consider what unique intrinsic (aka intensive) metal properties (such as density, viscosity, boiling or melting point) could be tested. For the provided activity materials (copper, aluminum, zinc, iron or brass), density is the only property that can be measured so groups experimentally determine the density of the "mystery" metal objects. They devise an experimental procedure to measure mass and volume in order to calculate density. They calculate average density of all the pieces (also via the graphing method if computer tools area available). Then students analyze their own data compared to class data and perform error analysis. Through this inquiry-based activity, students design their own experiments, thus experiencing scientific investigation and experimentation first hand. A provided PowerPoint® file and information sheet helps to introduce the five metals, including information on their history, properties and uses.
