preview of 'Using Jupyter Notebooks to Explore Waves' Activity

Using Jupyter Notebooks to Explore Waves High School Activity

Published on June 30, 2021

As an introduction to analyzing sinusoidal waves, students learn how to use a Jupyter Notebook. They learn how to identify the frequency, wavelength, amplitude, period, and phase of a simple sinusoidal waveform. As they learn how to label the parts and properties of the waves, they connect these characteristics of waves to various real-world wave examples such as ocean waves, visible light, and sound. Students will examine a mathematical model of a sinusoidal waveform and connect each variable to its corresponding wave property. They will manipulate each variable of the model using Python code in a Jupyter Notebook and examine the effect of changing each variable on the resulting waveform.

Published on May 26, 2021

This activity is meant to introduce students to the concept of industrial and safety engineering, using real-world COVID-19 prevention procedures (from their own school or researched online). Students consider cases where schools were forced to close due to outbreaks, then collect data and evaluate real-world procedures designed to prevent outbreaks. Their evaluation will lead students to determine how common processes are falling short and use that information to provide recommendations to their own school.

preview of 'Modeling Nuclear Damage from Cell Movement' Activity

Modeling Nuclear Damage from Cell Movement High School Activity

Published on May 26, 2021

This engineering design activity simulates building a model to visualize and measure DNA damage within the nucleus as the cell migrates through the extracellular matrix (ECM). As students learn more about the structural composition of the ECM and the nucleus, they come to understand that both the ECM and the nucleus vary in stiffness and elasticity. Mechanobiologists have recently discovered that this feature plays an influential role in regulating numerous cell functions, as cells have the ability to “sense” their mechanical environment. The stiffness of the ECM is particularly important in the spread of cancer throughout the body. In this activity, students model the movement of a cell through a stiff matrix and measure the impact on the nucleus as DNA damage caused by the stress of this movement in relation to the amount of nuclear lamins, the major architectural proteins of the animal cell nucleus, present.

preview of 'Engineering a Minion Rescue' Activity

Engineering a Minion Rescue Elementary School Activity

Published on May 1, 2021

The minions are stuck on a deserted island! Students research, design, create and test boats that can rescue the minions. They learn about the physical properties of matter as well as the construction of boats and buoyancy while they engineer a minion rescue.

preview of 'Shielding from Cosmic Radiation: Part 3 - Post-Launch Analysis' Activity

Shielding from Cosmic Radiation: Part 3 - Post-Launch Analysis High School Activity

Published on April 30, 2021

In this wrap-up activity, students analyze their findings from their launch! (Alternatively, they can independently analyze data sets without launching a balloon.) Students examine the radiation data collected from a balloon launched into near space to see if cosmic radiation shielding designs worked. Students explain their findings, which might require some research to show if this observation is correct and why. Finally, students make a comparison of the shielded and unshielded, control Geiger counters and analyze the results.

preview of 'Shielding from Cosmic Radiation: Part 2 - High-Altitude Balloon Launch Test' Activity

Shielding from Cosmic Radiation: Part 2 - High-Altitude Balloon Launch Test High School Activity

Published on April 30, 2021

This activity has students embarking on an ambitious design project: to measure the effect of shielding from cosmic radiation via a high-altitude balloon launch test. Students prepare their payloads for launch, making sure batteries are charged, payloads are complete, flight predictions have been made and approved, etc. On launch day, students launch a latex, high-altitude balloon that carries each space agency’s payload to near space. GPS tracking units follow the balloon flight path in real-time, so the location and altitude of the balloon during flight, when it bursts, and once the payload is on the ground. After landing, participants travel to the landing site and retrieve and examine the payloads.

preview of 'Shielding from Cosmic Radiation: Part 1 - Building the Payload' Activity

Shielding from Cosmic Radiation: Part 1 - Building the Payload High School Activity

Published on April 30, 2021

This activity has students embarking on an ambitious design project: to build a payload that measures the effect of shielding from cosmic radiation via a high-altitude balloon launch test. Each payload includes a Geiger counter, data collection device (Arduino and microSD memory card), and uses materials that will shield their Geiger counter from cosmic radiation. (Each payload also has a second, unshielded Geiger counter to act as a control.) By the end of the activity, each group has a completed payload ready to launch into near space and collect data.

preview of 'Shielding from Cosmic Radiation: Space Agency Scenario' Lesson

Shielding from Cosmic Radiation: Space Agency Scenario High School Lesson

Published on April 29, 2021

There is increasing interest in human space exploration beyond the Moon’s orbit, such as venturing to Mars. However, the effects of radiation are still a major concern for such travel. Astronauts need shielding from radiation. One testing method is to send materials into near space and measure radiation levels using Geiger counters. Teams of engineers on such projects need to be aware of design constraints, such as budgets, material limitations, and public support. Through role playing and problem solving, the first lesson sets the stage for a friendly competition between groups to design and build a shielding device to protect humans traveling in space. The instructor asks students—how might we design radiation shielding for space travel? Finally, the instructor presents the space agency scenario to students and hands out Arduinos while explaining the scenario, the roles, and the objectives. Students divide into groups and begin the process of forming their agency. Students get to know their partners and counterparts. Both agencies design logos and examine their missions. The computer scientists from each agency learn about Arduinos and basic computer coding.

preview of 'Lunar Olympics' Activity

Lunar Olympics Middle School Activity

Published on April 27, 2021

On your mark… get set… design! Students discover how sports arenas, rules, and equipment would change if the Olympic Games were conducted on the Moon. During the process, they learn about the engineering design process and physics concepts such as gravity, velocity, acceleration, and friction. They use free online design and programming tools which help them to improve their conceptions and design skills. This activity was developed to be implemented fully online; however, it could easily be adapted for in-class or hybrid classroom use.

preview of 'Energy Innovator: Be Your Own Generator' Activity

Energy Innovator: Be Your Own Generator High School Activity

Published on March 26, 2021

Exploring the phenomena of electromagnetism and current generation are great ways to help students gain an understanding of how these concepts are used in engineering design. This activity allows students to make sense of, design, and create their own magnetic field generator without the use of batteries. As they create their own generator, students learn how electricity can been created using circuits and magnetism—hence, discovering the phenomenon of electromagnetism! While thinking critically about how magnetic fields work, students develop a design for a generator using magnets, copper wire, discs, and LED indicator lights.

preview of 'Crystalline Cloth: Modeling Water Treatment Filters' Activity

Crystalline Cloth: Modeling Water Treatment Filters High School Activity

Published on February 27, 2021

Water filtration is a key engineering concept, and in this activity students become environmental engineers as they model membranes and membrane treatments to remove scaling during water filtration. Using cheese cloth to represent a simple membrane, students soak their “membrane” in a supersaturated salt (or sugar) solution and measure how much salt (or sugar) crystallizes on their cloth. They then research and analyze different treatments they can apply to their “membranes” to reduce the scaling (crystal growth). They apply and test their chosen treatments and then hypothesize which treatment method best prevents scaling on their “membrane.”
