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.

Creative Engineering Design: Model EV Design Challenge High School Activity

Published on March 19, 2024

Students collaborate creatively in teams (2-4 students) to design, build, test, and iterate a model electric vehicle (EV) car that runs on a battery-powered electric motor circuit. 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.

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.

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.

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!

preview of 'A Slippery Situation: Oil Spill Cleanup and Polarity' Activity

A Slippery Situation: Oil Spill Cleanup and Polarity Middle School Activity

Published on March 7, 2024

Students learn about the concept of polarity and mixing through the phenomenon of oil separating from water by simulating an oil spill that demonstrates the impact of these molecular qualities on the environment. In the first part of the activity, students get familiar with the concept of polarity and how it causes oil to float on water through molecular models and demonstrations. The second part entails a simulation of an oil spill in the ocean, where students are given a variety of tools and will engineer their own solutions to clean up the spill through trial and testing. Finally, they discuss the real-world methods used to clean up oil spills, and their impact on the environment.

preview of 'Periodic Table Intro: Parts of a Whole' Activity

Periodic Table Intro: Parts of a Whole High School Activity

Published on October 4, 2023

The Periodic Table is an icon of organizing for chemistry as well as other disciplines including chemical engineering. The table also represents an important way to understand how to sort and identify objects based on specific criteria. In this activity, students submit a picture of a unique “one-of-a-kind” item they own. They then create diagrams that sort these various items based on categories of their choosing. They discuss the process as a class, drawing upon similarities to the creation of the Periodic Table: identifying individual characteristics of an object/element, and sorting objects/elements into rows and columns based on similar characteristics.

However, the challenge lays in how to harness that energy in an effective manner—and that’s where engineers come in. In this activity, students learn how the sun can help us make electricity with a device called a solar panel. They are then presented with the challenge of the stationary solar panel versus the moving sun. Using the behavior of a sunflower following the sun throughout the day, students build upon and apply their knowledge of solar patterns, solar energy and plant needs as they engineer model solar panels that move to follow the path of the sun.

preview of 'To Infinity and Beyond: The Amazing Hydrogels' Activity

To Infinity and Beyond: The Amazing Hydrogels High School Activity

Published on September 21, 2023

This activity provides students with the background necessary to understand chelation—a type of bonding of ions and molecules to metal ions—to create hydrogels. During the activity, students use sodium alginate, an extract from brown seaweed, to create hydrogels. By using alginate-based compounds (in other words, compounds extracted from brown algae), these hydrogels are also nontoxic and non-inflammatory. All these properties make the alginates ideal for applications in pharmaceuticals, wound care, hygiene, and optometry.
