This ZOOM video segment shows how to create a self-contained environment and explores evaporation, condensation, and precipitation.

This is a long-term inquiry activity in which students investigate locations they believe harbor cellulose-digesting microbes, collect samples, isolate them on selective media, and screen them for cellulase activity. These novel microbes may be useful for the production of cellulosic ethanol. In the process they learn about plating techniques, serial dilutions, symbiotic relationships and enzyme specificity. Two methods are provided, one focusing on isolation of pure microbial strains, the other focusing on finding symbiotic communities of microbes. The companion activity is here: https://www.glbrc.org/outreach/educational-materials/bioprospecting-cellulose-degrading-microbes-filter-paper-assay

Cryptocurrencies like Bitcoin rely on blockchain technology and crypto mining, which consume massive amounts of electricity and have significant carbon footprints. The lack of transparency and regulation in the industry raises concerns about the economic, social, and environmental costs associated with crypto mines.

This board game challenges players (ages 10+) to build a spaceship and fly to a black hole. The game provides opportunities for understanding phenomena based on current black hole research. During the game, players will experience the dangers and excitement of a real space mission, and learn about the nature of black holes by launching scientific probes. The game can be played competitively or as a team (instructions are also provided for playing in large groups. Black Hole Explorer consists of: Game Board, Game Rules, Spacecraft Data sheets, Science Briefing Room document, Event cards (28), Probe result cards (12), Energy tokens (140). Game components are available as PDF downloads; dice and game pieces must be provided by the user. NOTE: tokens and cards need to be cut to size from letter-size cardstock.

How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve.

In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.

In this video, Jonathan joins Charlie Donilon on his shark charter boat in Rhode Island, Massachusetts, and learns about how shark tagging has shed light on the biology of and behavior of Blue sharks. Tagging has shown that these incredible swimmers actually migrate completely across the Atlantic ocean. Jonathan tries his hand at tagging a shark and then swims with Blue sharks. We also learn that Blue sharks are not nearly as vicious as they have been reputed to be, and the divers are actually able to pet the sharks! Please see the accompanying study guide for educational objectives and discussion points.

Students will be able to evaluate a simple blueprint including weld symbols and convert metric measurements to SAE.

Students are introduced to the circulatory system, the heart, and blood flow in the human body. Through guided pre-reading, during-reading and post-reading activities, students learn about the circulatory system's parts, functions and disorders, as well as engineering medical solutions. By cultivating literacy practices as presented in this lesson, students can improve their scientific and technological literacy.

This lesson ties in our 7th grade science curriculum where students study the Systems of the Body. It also looks at how these systems function in relation to athletics. Students are to design an app that looks at these systems and how an app can help an athlete train for their sport.

This lesson explores several of the recording mediums used throughout the early 20th century. Along the way, students learn how sound waves travel, how the human brain converts those waves to recognizable sound and how inventors learned to capture them on wax, magnetic tape, and finally as digital information. From there, this lesson then investigates the creative impulses and scientific developments that turned multitrack recording from a dream to a reality. Students also get hands-on experience using the Soundbreaking Mixing Board TechTool, which allows them to be sound engineers, playing with "the mix" of a multitrack studio.

Find out how serious head concussions can be in this video segment adapted from NOVA scienceNOW.

In this interactive activity from the Building Big Web site, use your knowledge of bridge design to match the right bridge to the right location in a fictitious city.

Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

This activity s a student project to construct and test the load bearing capacity of a scale model bridge from toothpicks.

In the world in which we live, individuals are faced with technological challenges that were perhaps never anticipated or envisioned. Forty years ago, no one could have anticipated the challenges and opportunities that cell phones bring, let alone text messaging. At times, we are faced with design challenges that require us to think “outside the box” and use creative design processes rather than relying on just one possible solution. Specifically, structures are designed with a particular purpose, environment, life span, and culture in mind. Engineers must weigh these factors to produce optimal designs.

Engineering and designers regularly keep a design journal. Documentation of design thinking strategies, through sketches, notes, and diagrams, is an important aspect of the creation of an engineering design journal.

BRIGHT Girls was a project to build broader participation in the sciences, led by the University of Alaska Fairbanks and funded by the National Science Foundation. We sought to increase students' motivation and capacity to pursue careers in STEM by engaging them in studies of nearby natural environments. The developed lesson plans may be used in formal or informal educational settings, e.g., in a summer academy or across multiple class periods. These investigations help students explore the relationships among life history and ecosystems, connecting biology to geology and remote sensing.

"Build It Yourself: Satellite!" is an online Flash game hosted on the James Webb Space Telescope website. The goal of the game is to explain the decision-making process of satellite design. The user can choose to build a "small," "medium," or "large" astronomy satellite. The user then selects science goals, wavelength, instruments, and optics. The satellite is then launched on the appropriate rocket (shown via an animation). Finally, the user is shown what their satellite might look like, as well as what kind of data it might collect, via examples from similar real-life satellites. Satellites range from small X-ray missions without optics (like the Rossi X-ray Timing Explorer) to large missions with segmented mirrors (like the James Webb Space Telescope).

Students wire up their own digital trumpets using a MaKey MaKey. They learn the basics of wiring a breadboard and use the digital trumpets to count in the binary number system. Teams are challenged to play songs using the binary system and their trumpets, and then present them in a class concert.

Build fractions from shapes and numbers to earn stars in this fractions game or explore in the Fractions Lab. Challenge yourself on any level you like. Try to collect lots of stars!
