Smelling the Difference Between Healthy & Cancerous Cells High School Activity

Published on May 10, 2024

This activity utilizes simulated cancerous and noncancerous cell cultures, probes, and Arduinos to teach students about current research that involves mapping nerve signaling patterns in insect (locust) brains in response to odor molecules produced by healthy versus cancerous cell lines. A connection is made to cellular respiration and metabolism because these are the processes that cause the cell cultures to produce different odorous metabolites. The simulated cultures will contain fluids of varying pH values instead of using solutions with volatile compounds. Students use pH probes in the solutions to observe a number and lighting pattern that is programmed into the code of the Arduino. Students use observations to make conclusions about which patterns represent cancerous cell odors versus healthy cell odors with “known” cell cultures. After recording data, students select “unknown” cultures and determine whether the unknown samples are cancerous or not based on the earlier established patterns. Students graph, analyze, and summarize the data to write a claim, evidence, reasoning (CER) paragraph.

Published on April 25, 2024

Students embark on an interactive journey through the Engineering Design Process (EDP) to develop, test, and refine a system aimed at enhancing the accuracy of a ball thrown or flicked toward a small target. This hands-on activity serves as an analogy to the process of training machine learning systems, providing students with a tangible understanding of how these systems utilize data and feedback mechanisms to improve performance. Students are also taken from a type of learning they are more familiar with, including visual feedback for the learner, toward an increasingly more abstract method of learning that only involves numeric inputs and outputs.

preview of 'Engineering Friction and Grip' Activity

Engineering Friction and Grip Middle School Activity

Published on April 23, 2024

Students engineer surfaces to control and modify friction and grip as they design and build a tabletop game that uses sliding friction as the main component of its mechanics. Students first observe surface roughness on a variety of surface materials using a digital microscope and explore how engineers use surface modifications to manage friction. They then investigate and compare the friction and grip on multiple surface materials using an inclined plane. Applying the concepts of surface roughness and surface modification, students work as engineering teams to create a tabletop game that uses sliding friction as a main game mechanic. Students go through the steps of the engineering design process, from ideation to prototype development. Students test their own games to balance relevant parameters (surface roughness, speed, board design, game rules, etc.) to improve their prototypes. Students review the prototypes of their peers and offer feedback for further improvements.

Engineering a Ping Pong Ball Retriever Middle School Activity

Published on April 17, 2024

Students use the engineering design process while learning about accessibility for people with physical disabilities in Egypt. Students are challenged to create a reusable prototype to help a wheelchair table tennis team pick up ping pong balls. Before building their prototypes, students research the trash and waste problem in Egypt, compiling a list of sustainable materials that can be used to build their devices. Students then individually brainstorm and plan at least two different devices before coming together in teams to develop one group prototype design. After building, testing, and improving their prototypes, student groups present their prototypes to the class.

Students use a hot plate, ice-water bath, and common lab equipment to prepare a viscous or semi-viscous liquid at cold, room, and warm temperature levels. Students measure the mass, volume, and density of their specific liquid to determine the viscosity of their liquid at different temperatures. Students compare their liquid to another group’s liquid to compare and determine any trends with temperature and viscosity.

preview of 'Insulator Design Challenge' Activity

Insulator Design Challenge Middle School Activity

Published on April 4, 2024

Students engage in the engineering design process while identifying the relative thermal conductivity of different materials. Students apply their understanding of heat transfer to build an insulator to prevent heat loss or gain from an object. Students practice the engineering design process by building their insulator. At the end, they reflect on the design process and the effectiveness of their product.

preview of 'What’s Your Angle? Assessing Wave Refractions' Activity

What’s Your Angle? Assessing Wave Refractions High School Activity

Published on March 22, 2024

Students observe wave refraction in different mediums. They trace the path of light waves of a laser entering a medium and exiting the medium. Then they measure the angle of the refracted ray using a protractor to get an understanding of the concepts of how refraction works in different mediums. By the end of the lesson, students will be able to identify which substance refracted light the most and hypothesize a pattern of refraction based on the densities of the substance.

Students apply and integrate the engineering design process, forms of energy (electrical, chemical, mechanical), and related physics concepts, such as simple machines (pulleys, axles and wheels), complex machines (gears), and motion of objects (friction, speed) to maximize the performance of their model EV. Throughout this project-based engineering design challenge, students learn about EV-related environmental justice concepts, including air quality, health, environmental and transportation connections. In a final design expo, teams have the opportunity to present about their final EV model, their design process journey, and their perspectives on the intersection of engineering and environmental justice in regard to EVs. Teams can also participate in fun model EV race and aesthetic design competitions.

preview of 'Robo-mentum: Mass, Velocity, and Momentum Relationships' Activity

Robo-mentum: Mass, Velocity, and Momentum Relationships High School Activity

Published on March 19, 2024

Student groups use STEM vehicle kits to learn about the relationships between linear momentum, mass, and velocity. Each group assembles their vehicle and then runs tests and gathers data to calculate their vehicle’s velocity/speed and linear momentum. This data is then used to create scatter plots of the three variables (linear momentum, mass, and velocity/speed), and the Desmos graphing calculator is used to model a direct relationship using linear regression, as well as model an inverse relationship using exponential regression.

preview of 'Exploring Light With Holographic Chocolate' Activity

Exploring Light With Holographic Chocolate Middle School Activity

Published on March 8, 2024

Students explore how light interacts with matter. Using the principles of spectroscopy, they learn how light can cause molecules to react by entering into an excited state. This activity addresses diffraction grating, which is in a spectrometer (a specialized instrument used to track and measure the path of different wavelengths of light). This instrument is used in many applications that study light-matter interactions. Students apply a diffraction grating to chocolate, allowing them to observe the ray of light being separated into different colors and wavelengths and how light can interact differently with common materials by altering their properties. Students further explore light by designing light-powered products and presenting their designs to the class.

preview of 'Ready, Set, Solar! Design a Solar Powered Car' Activity

Ready, Set, Solar! Design a Solar Powered Car Elementary School Activity

Published on March 7, 2024

Students learn that solar energy is a renewable energy source from the sun that can be collected and used to power different items, and that solar panels allow us to gather this energy in one place and use it as electricity. As a renewable resource, the sun provides a clean and abundant source of energy that can help reduce pollution and harm to the environment. To model this process, students use a solar powered rover kit to make a car out of recycled materials. In groups of two, students use the Engineering Design Process (EDP) and follow each of the steps to complete, test, redesign, and retest their cars. Students test their car in the sun with the panel at two different angles and then once in the shade. What worked best? Then the race is on!
