Earthwatch Fellowship for Teachers

Share |
| 1 Comment

Middle school teachers, grades 6-8, interested in investigating ocean sciences or climate change are invited to apply for the 2011 Earthwatch Educator Program sponsored by Earthwatch and Northrop Grumman. The program provides a fellowship for an innovative hands-on expedition, an inspiring experience that teachers can then share with classrooms.

Last year, Erin Moore, a teacher in Illinois, was selected to participate in Northrop Grumman Foundation's Weightless Flights of Discovery Program. As Erin reported on the Science Buddies' blog, the experience of the Zero-G flight was exhilarating and life-changing, from start to finish.

The following Earthwatch expeditions are planned for 2011:

  • Coastal Ecology of the Bahamas

    6/27 - 7/8, 2011

    Be a part of a team supervised by Dr Kathleen Sullivan-Sealey as you explore the Bahamian archipelago, a unique ecosystem in the northeast Caribbean Sea.

  • Climate Change at the Arctic's Edge
    6/19 - 6/29, 2011
    Exploring the carbon-rich peatlands in the Arctic tundra will bring issues related to global warming rushing to the surface. Teams working with Dr. Peter Kershaw will monitor ecosystem changes in response to global warming and investigate changes in the permafrost—and the risks related to the release of greenhouse gases if the permafrost thaws.


Middle School teachers (grades 6-8) from Northrop Grumman communities are eligible to apply for the program (except for educators who participated in the 2009 or 2010 Weightless Flights of Discovery program or the 2009 or 2010 Space Academy for Educators). The deadline for application is February 4, 2011.

For more information, or to fill out an application, visit the Northrop Grumman Earthwatch information page.

 

Earlier this week, we posted a list of cool science-y things you might add to your own wish list... things that would be fun to explore and might win holiday brownie points with Mom and Dad for sheer educational value. Hopefully you made sincere, compelling, and scientifically sound arguments. But now it's time to take a look at grown-up gadgets and science toys. Do you need to buy something for Mom, Dad, Uncle Joe, or Grandma? Maybe you've been thinking about what to give? Maybe you're hoping for perfect holiday brownies, in addition to the brownie points? There are tools that can help with that!

We asked the Science Buddies staff—the group of people who bring you all of our great science project ideas and resources—what was on their wish lists. Not surprisingly, they had some "scientific" answers! There are some unexpected but cool gift ideas on their lists... items, tools, and gadgets that you might be able to use in your own projects!

So, in the spirit of giving, we pass along this roundup of staff wishes. You might just spot the perfect gift for someone on your list... and we'll help by offering a few ways you might be able to "borrow" it for your own exploration!

(Parents, if you are reading along, we think you'll find some great suggestions here for things you might really use—and that would give you exciting new ways to bring more science into your house and into your dinner table conversations.)

  • Courtney (a.k.a. "Science Mom") wants a digital kitchen scale

    wishlist-scale.jpg"As I get older and more interested in higher quality, more expensive kitchen gadgets—and as I become a better cook and baker (which my family enjoys!)— I find that I really want to have a more accurate scale since weighing ingredients is the most accurate way to determine quantity."

    The good for me, too, angle: A digital scale can be used in many science projects that require accurate weighing, but that doesn't mean it's just for food (or just for the kitchen). A shiny new digital scale would come in handy in the Build a Raft Powered by Surface Tension project (Difficulty: 5-6). Or, if you do want to experiment in the kitchen, check out this materials science abbreviated project idea, The Fluffiest Muffins: Flour Type and Muffin Density* (Difficulty: 5).

    wish-monitor.jpg
  • Tina wants a heart rate monitor

    "I am training for next year's dipsea race, a 7.5 mile point-to-point off-trail race from Mill Valley to Stinson beach. A heart rate monitor will help keep me on track."

    The good for me, too, angle: Tracking heart rate is a great way to monitor how hard your heart is working. You could test-drive a new heart rate monitor instead of measuring pulse rate in the Fear Factor: Using Pulse Rate to Measure Emotion human behavior project (Difficulty: 5-8). Even younger students can use a tool like this as they explore A Day in the Life of Your Heart (Difficulty: 2-3).

    wish-binocs.jpg
  • Ken (founder, President, and astro-photographer) wants Canon Image Stabilized Binoculars

    "It's hard to hold binoculars steady enough to see clearly, but technology has come to the rescue. Image stabilized binoculars compensate for your every wiggle, holding the image rock steady, so it's easy to see the details on the moon, nebula, or birds!"

    The good for me, too, angle: After you satisfy your Spy Kids-inspired curiosity, these high-power binocs can help you observe things you can't easily get close to—or animals whose behavior might change if you get too close. Take a closer look at bird anatomy and patterns of adaptation in the Can You Predict a Bird's Lifestyle Based on Its Feet? zoology project (Difficulty: 3).

    wish-sandra.jpg
  • Sandra wants a Molecular Gastronomy Artistre Spherification Starter Kit

    "In my family we're hooked on the TV show 'Top Chef,' which is where I first heard about molecular gastronomy. Talk about a tasty fusion of chemistry and food! So, I'm hoping that there's a molecular gastronomy starter kit sitting under our Christmas tree this year. If so, I'll be experimenting and tasting my way into the New Year figuring out how to make fruit 'caviar' and Nutella powder."

    The good for me, too, angle: Besides getting to eat the yummy concoctions you create, you can investigate what makes the recipes work—and even invent a few of your own. You can get started experimenting with ingredient swapping projects like: Chemistry of Baking Ingredients 1: How Much Baking Powder Do Quick Breads Need? and Egg Substitutes (Difficulty: 2-5). And if Sandra gets her wish, she's promised to share new molecular gastronomy project ideas in the New year!

  • Rebecca wants eye droppers

    "My toddler knows his colors, so we want to start introducing the concept of mixing colors to make new colors. With eye droppers of water and food coloring, he can see the effect of mixing these colors on paper towels, rather than just mixing his ketchup and mustard at the dinner table."

    The good for me, too, angle: Eye droppers are a staple in many lab projects. You can put them to innovative use making your own markers (Difficulty: 3). Or, you'll find them handy as you study plant biology in the Plants on the Move! Experiments with Phototropism project (Difficulty: 6).

  • Kristian wants a Thermochron iButton -40°C thru +85°C data logger

    "We sometimes go on overnight backcountry skiing trips and are learning to build snow shelters (quinzhees). It would be cool to compare the temps inside the quinzhee compared to a tent or other structure."

    The good for me, too, angle: Lots of projects require frequent temperature readings. Wouldn't it be great to gather all that data even when you aren't there to read the thermometer? With the high-tech iButton (you can hook it up to your computer later to upload the data), you're all set to to explore an environmental engineering project like Rooftop Gardens: Are They a Cool Idea? (Difficulty: 4).

    wish-watch.jpg
  • Michelle wants a new stop watch "Many of the projects I work on require timing reactions, measuring ball pitches, calculating velocities, and so on." (She also put a new "tape measure" on her list. She's a scientist through and through!)


    The good for me, too, angle: A good stop watch is a must-have for many physics or aerodynamics projects! Grab a stop watch as you hit the pavement for the Popping an Ollie: How Skateboarders + Physics = A Really Cool Trick sports science project (Difficulty: 4). Or, take an investigative approach to an edgy sport in Paintball Ballistics (Difficulty: 7).

    wish-weather.jpg
  • Kaarin wants a weather station

    "It would be great to be able to see the outside temperature and humidity from inside the house."

    The good for me, too, angle: With an in-home weather station on hand, you can track all kinds of weather patterns, or explore the fog in the Foggy Forecasting: What Weather Factors Create Radiation Fog? project (Difficulty: 6).

    wish-nano.jpg
  • Marisa wants digital BBQ tongs and a Nano-UV Disinfection Scanner

    "Digital tongs take the guesswork out of whether or not the meat is 'done.' Nobody likes food poisoning! And the scanner uses Nano-UV light to destroy microorganisms in 10 seconds—without toxins or side effects."

    The good for me, too, angle: Set your Nano-UV light loose on germs in the Death Rays: What Duration of Ultraviolet Exposure Kills Bacteria? microbiology project (Difficulty: 7).

    (Marisa also asked for an Orbitor Electronic Listening Device. (You may or may not want your parents to have that!)

  • Claire wants noise canceling headphones

    "I am traveling for the holidays and am hoping noise canceling technology might give me a peaceful flight!"

    The good for me, too, angle: You might find that noise canceling headphones can improve your focus when you're studying—or help you block out a younger sibling! But if you want a science spin, you could adapt the Frequency-Dependent Sound Absorption project to explore what frequency and volume are necessary to be heard through noise-canceling headphones (Difficulty: 7).

    wish-extensiontubes.jpg
  • Amy wants a set of DSLR extension tubes

    "I really want a full-frame (non-crop sensor) upgrade to my DSLR—or at least a good 100mm prime lens. But I'd settle for a set of extension tubes for some plug-and-play variety and an easy macro boost !

    The good for me, too, angle: Extension tubes are not the same as a new lens, but they have the effect of magnifying the image and thus giving you the ability to explore macro photography—even if you don't have a bag full of lenses. A comparison of the quality of photos shot with extension tubes versus true macro lenses—or a quantitative study of the amount of light required for use with extension tubes—would make a great independent study! To get started thinking about how to construct a project like this, look at the Camera Lens Testing project idea (Difficulty: 5-9).


wish-timer.jpgThe reality... "kitchen" gadgets were high on the lists! There were also requests for digital kitchen thermometers and digital (and loud) kitchen timers.


We hope you find the perfect gift for anyone on your list. If you can "also" use the gift in your next science project, it's all good!

Scientifically Speaking: A Holiday Wish List

Share |
| 1 Comment

If you're making lists and checking them twice this holiday season, make sure you put on your science cap as you think through what you really want! Well, that would be our suggestion. There may be many things on your list, but sometimes the best gifts to receive are ones that you can use over and over and over again, ones that will inspire and challenge you, and ones that let you explore, discover, create, and, yes, play. Plus, we know that moms and dads, aunts and uncles, and especially grandparents, like to give things they know are good for you (like socks) or educational (like a new dictionary).

Many Science Buddies Project Ideas use kits or tools that can be fun to explore, can be worked into a school project, and can be used again for other experiments as well. It can't hurt to note on your list that what you're asking for could become the seed of your next science fair project—or could launch you on a new career path! (Psst... mom... dad... did you hear?)

We think science lurks in just about everything, so there are plenty of things you might ask for, but we've looked through our Project Ideas and pulled our Top 12 science gizmos or tools--based on sheer science fun (from our perspective). To help you make a convincing appeal on your list, we're giving you the goods here: a relevant science project and a set of terminology you can use when writing up your list.

  • Frightened Grasshopper Kit: Nano-style bugs and bots of all kinds can be fun, especially when they seem to have a mind of their own! Explore solar power and electronics as you build your own solar-powered insect. No 'pet-walking' required! Want to teach your light-loving bot a trick or two? Check out this project idea to figure out how much light it needs (Difficulty: 3-4). Terms to use: radiant energy , electrical energy, solar panel, kinetic energy , wattage.

  • Picoboard: If you love video gaming and especially dig cool features that depend on user input wish-picoboard.png(like blowing the notes to play the flute in Zelda on the Nintendo DS), you can have fun building your own apps in the free Scratch programming environment. When you hook a Picoboard to your application, you've got the ability to use sound, motion, light, resistance, and other input values. For a project that can launch you into PicoBoard programming, look at Pinwheel Magic: Take a Spin with Animation (Difficulty: 5). Terms to use: algorithm, program, flowchart, sensors, user input.
  • wish-tiedye.jpg Tie Dye supplies: Tie-dying t-shirts or fabric to make scarves and pillows lets you transform ordinary fabric into something that shows off your own unique personality and color sense. You can explore fiber-reactive dyes and how they work differently with different types of fabric in the How to Make the Boldest, Brightest Tie-Dye! project (Difficulty: 5). Terms to use: natural fiber, synthetic fiber, cellulose, protein, molecule, saturation.
  • Papyrus paper kit: Making your own "papyrus" will give your art a hefty combo of science and history. If you've tried papermaking before (deckle ring a bell?), you can explore the ways in which making a sheet of papyrus differs, but you'll also be exploring materials science. The Pounding Papyrus: How Ancient Egyptians Made the World's First Paper project lets you examine differences in ancient and modern paper making techniques (Difficulty: 6). In the end, you'll have cool paper to add to your scrapbook or next bookbinding project. Terms to use: Ancient Egypt, Cyperus papyrus plant, bamboo, cuneiform tablet, pulp, tensile strength, tensile force.
  • LEGO Mindstorms:
    Take your LEGO building to new heights when you add in the programmability of LEGO Mindstorms. You can get started exploring the world of robotics in the Go, Gadget, Go! Building Robots with LEGO® Mindstorms® project (Difficulty: 6). But that's just the beginning. There are many great guides that can help you build cool mechanical tools—from LEGO. If you've got a parent always complaining about LEGO begin underfoot, you might mention that you could build a LEGO picker-upper—or a brick sorter! (Difficulty: 7). Terms to use: robotics, programming, electric engineering, engineering method.
  • Remote-Control Helicopter: Whether it flies indoors or outdoors, RC vehicles can be your key to aerodynamic—and electronics— investigation. Once you're done sending it buzzing and hovering around a sibling (or after the family pet), you can settle down to some hard-core aero-exploration in Helicopter Liftoff: How Does the Speed of the Rotor Affect the Amount of Lift? (Difficulty: 7). Terms to use: blade, rotor, airfoil, lift, leading edge, angle of attack, digital tachometer, revolutions per minute (rpm).
  • XPULT catapult: Launching balls through the living room doesn't get much more fun! wish-xpult.jpgBut there's both mechanical engineering and physics at hand as you work to achieve the perfect shot. As you experiment with the XPULT catapult in a project like Bombs Away! A Ping Pong Catapult, you'll explore trajectory and launch and pullback angles (Difficulty: 4-5). Terms to use: basic physics, potential and kinetic energy, ballistics, resistance, friction.

  • wish-sunprint.jpg
    Sun Print Paper: The days of December may not invite you to spend much time outside, but with a pack of sun print paper, you'll be watching for the first sunny day and the chance to explore photograms. In the Colorful Chemistry Creations: Make Your Own Sun Print with Color and Sunlight! project, you can investigate how effective various colors are when it comes to filtering UV light (Difficulty: 3-5). You can also pick up a bit of photography history in our blog entry on sun prints. Terms to use: light-sensitive, Berlin green, water-soluble, chemical reaction, Prussian blue, insoluble, light filter.
  • Telescope: What better way to put the skies in perspective at varying times of the year than with your own telescope? Like a SLR or DSLR camera, a telescope is something your whole family can use—time and again. What you explore or investigate through the lens may be galactic in scale, but you can get started with the Similar Triangles: Using Parallax to Measure Distance project (Difficulty: 7). Don't forget, the Science Buddies—Lick Observatory Astronomy Contest is underway! Terms to use: motion parallax, arc minutes, arc seconds.

We hope you have fun—and get cool science and engineering "toys" you can really use. Who knows what you might discover? Or invent? Or uncover?
