STEM@Home: Citizen Science

Pardon me, are you Citizen Science? No, that’s not a hip new prefix for your name – it’s a description of your new summer hobby! Citizen science is science where everyone participates – including PhDs, amateurs, students, volunteers. Then, professional researchers use the collected data to come to real-world conclusions.

Why citizen science? Well, we live in a big world with big problems – it stands to reason we need big solutions. By working together, citizen science helps gather positively gi-normous sets of data from across the globe, and over years and even decades. That means scientists can develop stronger solutions to environmental, health, and ecological problems. Who wouldn’t want to be a part of that?

SciStarter is the place to kick off your hopefully life-long citizen science career. Over a thousand projects are listed – some gathering global data, some more locally focused. Most of them can easily be done while maintaining safe social distancing and exploring our wonderful state and county parks. Check out a few of our favorites below!

SciStarter Snakes: Michigan Herp Atlas

As anyone who’s visited the Van Kley Animal Museum knows, we love our Michigan herps. Say what? Herp stands for Herpetofauna – or the group of animals including reptiles and amphibians. Ever hear the spring peepers disturb a still evening with their noisy croaks? Or jumped when a garter snake scurried across your path? You’ve interacted with some of Michigan’s native herpetofauna – and the Michigan Herp Atlas wants to know about it!

Slither on over to the SciStarter Michigan Herp Atlas page to learn more about the project and register for the Michigan Herp Atlas.

SciStarter Kites: Public Laboratory Balloon and Kite Mapping

Snakes not your thing? We won’t tell. How about a family project that uses helium balloons and digital camera imagery to create aerial maps of your neighborhood and city? Now we’re talking!

The Public Laboratory Balloon and Kite Mapping project takes a little up-front prep work, but your contribution helps create high-resolution maps that can be used for environmental research. And there’s no limit to the number of maps you can make!

Let’s go fly a kite! Visit the SciStarter Public Laboratory Balloon and Kite Mapping page to learn more and join the Public Lab mapping community!

STEM@Home: For the Birds

“Bird Song Hero” and The Cornell Lab of Ornithology Bird Academy

Ah, the sweet sounds of a Michigan spring day. The whisper of a breeze, rustling through branches just burst into leaf. The burble of a creek, swollen with snowmelt and April showers. The vibrant trills of songbirds, swooping and nesting overhead. Wouldn’t it be perfect if we could interpret those liquid melodies, and commune with our feathered friends? What might they be saying, those dainty winged creatures?

  • “Hey! That’s my nest! Get out of here!”
  • “Dude, check out my awesome plumage!”
  • “We’re under aerial attack! Duck and cover!”

Huh. Well then. Perhaps the aviary world isn’t as serene as we imagined… but it’s definitely a whole lot more interesting! Spring is the perfect season to find out more about the complex and crazy world of birds all around us. Luckily, The Cornell Lab of Ornithology’s Bird Academy has a virtual toolkit to start your birding adventure off right.

Bird Academy

Definitely not a Hogwarts for birds, Bird Academy is chock-full of videos, tutorials, and games to make learning about birds not only easy but fun. Videos give a solid introduction to different birding concepts, like the “Inside Birding” series that runs down all the basic bird ID concepts. Yeah… birding. That’s a verb now. Also, you’re a “fledgling” birder. See what we did there? Classic birder joke.

The Bird Academy Learning Games page is also particularly fabulous, with thoughtfully designed interactive games for all ages. Unsurprisingly, surrounded by the natural beauty of Earth’s birds, the scientists at Bird Academy created visually compelling games and virtual experiences that suck you in to the world of birds. Check out one of our favorites, Bird Song Hero, below!

Bird Song Hero

One of the most basic skills in a birder’s toolkit is being able to identify what birds are around. But there’s a problem for us curious investigators. Not only are birds expert at camouflage, but they’re as comfortable flitting about thirty feet in the air as pecking for worms in the dirt. Humans? We’re what you might call “grounded.”

Enter Bird Song Hero, an interactive online game that helps you train your ear to figure out what birds are around you using only their distinctive calls. Using spectrograms – technical images that “show” what a bird’s song looks like – lets you quickly learn how to differentiate bird calls by visualizing what you hear!

  • On the Challenge Level, be sure to listen to all three of the bird calls as often as you wish. Can you “read” the spectrograms when the birds sing?
  • Beat the Ultimate Level and score 90% or above. Don’t get tricked by the space robot!
  • Take it past the game and to the biggest, best level… Reality! See if you can identify the birds tweeting in your own backyard with just your own two ears.

Check in with ExploreHope all summer long for fun, hands-on ways to engage with the amazing world all around us.

STEM@Home: LEGO Lesson Love

Explore the world of simple machines with LEGO challenges from Frugal Fun 4 Boys and Girls!

Photo attribution: woodleywonderworks

Sure, your LEGO blocks have been VIP of the toy room for years now. Your minifigs could populate a small city. You’re got LEGO Hogwarts, the LEGO Death Star, and the Eiffel Tower (in LEGO) in places of honor in your room. But did you ever think…. did you ever believe… that you could master entire science concepts using only LEGO? Believe it, my friend – that day is here.

The LEGO-loving family behind Frugal Fun 4 Boys and Girls have put together all sorts of amazing LEGO demos, including LEGO explorations of the six simple machines used in engineering. Challenges range in difficulty from preschool to high school, so every learner can get their brick on!

Challenge 1: LEGO Bridge

Whether you’re just jumping into the concept of building with LEGO, or have a totally self-designed LEGO city in your basement, constructing bridges offers challenges for all builders. Start with a 6″ span and work up from there. The first challenge is getting the bridge to stay up… then there are so many ways to push its limits.

Bridges explore classical building concepts like arches, columns, tiling, etc. They introduce the concepts of extension (where the bridge pulls apart) and compression (where the weight is being concentrated). Each of these forces require different solutions to provide the strength and balance of a bridge.

  • Might is right: Check how strong your bridge is – stacking on lots of identical objects is a great way to compare strength between bridges. Consider soup cans, board books, or matchbox cars.
  • Go the distance: Once you master six inches, expand, expand, expand! Do the same techniques work on a bridge with an eighteen inch span?
  • So inspirational: Google “famous bridges” and find some new techniques. How do designs change as materials change?


Challenge 2: LEGO Pulley

Pulleys are one of the six simple machines that show up in countless ways throughout our modern world. How do cranes lift heavy loads to build sky scrapers? Pulleys. How do Boy Scouts quickly run flags up poles? Pulleys. How do elevators lift, rock climbers safely ascend, and red velvet curtains swish across the stage? Pulleys!

Using just LEGO wheels, bricks, and string, you can build simple and compound pulleys to explore how they use force redirection and mechanical advantage to make lifting heavy loads easier.

  • Big spender: How many pennies can you lift with a simple (one-wheel) pulley?
  • Compound interest: Can you use compound pulleys to lift more pennies than the simple pulley?
  • It wheel-y matters: Build a simple pulley with two different wheels styles. Does the choice of wheel make a difference in how the pulley operates?


Challenge 3: LEGO Waterwheel

Sunny days are on their way and this LEGO build will let science class take place outdoors. Using an inclined plane (another simple machine!) and LEGO, explore fluid dynamics, waterwheels, and hydraulic engineering!

  • Ramp it up: Does your watercourse behave differently at different ramp angles? What about with a trickle of water vs. a deluge?
  • Divide and conquer: Can you design a way to divert 25% of the water away from the main watercourse? How can you measure your results, beyond eyeballing it?
  • Minimalism is so trendy: What are the fewest bricks you need to divert water successfully?

STEM@Home: Earth Day, Your Way

Did you get your party hats? Crepe paper streamers? Make sure to blow a noisemaker or two, because April 22, 2020 is a special day for Planet Earth – it’s the 50th anniversary of Earth Day! Sure, 50th anniversaries are technically known as “golden” anniversaries – but don’t worry, Earth isn’t expecting anything flashy from you. Phew!

From appreciating the wonders in your own backyard, to making more sustainable shopping choices, there are plenty of ways to show your love and appreciation for Planet Earth in our everyday lives. Check out some of our favorite suggestions below!

STEM@Home: Dyson Engineering

Week 5: The James Dyson Foundation Challenge Cards

More than vacuum cleaners – although their vacuums ARE boss. More than super-fast hand dryers, bladeless fans, and space age heaters – the Dyson name goes along with creative, clever solutions to everyday problems. Hey! You’re clever! You’re creative, too. And you certainly live every day in the real world. So let’s start tackling some around-the-house engineering challenges, the Dyson way.

The James Dyson Foundation offers two kinds of challenge activities: 44 downloadable “challenge cards,” with shorter activities illustrating a specific concept, and six more open-ended video challenges, offering kids a chance to play around with the design process a bit more. One of each is highlighted below – so pick your path and let’s get started!

Challenge 1: Build a Cardboard Chair

Got any old boxes piling up in the recycling bin? Amazon packaging and old banana boxes will do, but so will cereal boxes, shoe boxes and any kind of cardboard you can find.

Using only cardboard – no glue, tape, or nails – you can make a chair you can really use! Discover the amazing strength properties of cardboard, and explore different design principles engineers use to make those super-sized diaper boxes able to stack sky-high.

  • Open House: Sketch all the different types of chairs in your house you could use as a model. Which one will be most successful in a cardboard version?
  • Mother Load: Test your chair’s load-bearing capabilities with differently-sized people in your house. Can your chair hold both kids and adults?
  • Expand-O-Matic: Now that you’ve got some building tricks up your sleeve, choose another piece of furniture to recreate in cardboard. Bookcase? Coffee table? Hey, maybe even a cardboard vacuum!

DON’T SIT THIS ONE OUT: Info, tips, and more HERE.

Challenge 2: Underwater Volcano

Volcanoes are equal parts terrifying and amazing, but their underlying process is even more incredible. Convection – the way heat rises and falls in liquids and gases – governs not only how volcanoes erupt, but how storm systems move in the atmosphere, how ocean currents swell, and even how oatmeal bubbles in a pan!

The convection connection (that’s what we call it in the biz) is how loads of natural processes work – and we can model it with this nifty trick in Dyson Challenge Card #2. Using just five items (a big jar, water, food dye, string and a salt shaker) get up close and personal with the most important swirling current you’ll ever meet.

  • STEAM-y Lava: Make a flip book illustrating what happens to your underwater volcano once you drop the hot salt shaker in the cold jar. Explosive!
  • Weather or Not: Dig deeper and discover how convection is connected to the weather. Start out with the NOAA SciJinks website.
  • Go Big, Already At Home: Your mission: create the most dynamic eruption possible with your underwater volcano. Hint: what makes the water inside the salt shaker different from the water outside it?

STEM@Home: Potter-ology

Week 4: We Are Teachers – Harry Potter Science

Calling all Potterheads! Taking a break from syllabi and curricula doesn’t mean no more mischief to manage. Nurture your wizard-in-training with this great roundup of real-life science activities at We Are Teachers inspired by the magical world of Harry Potter.

Hagrid’s pounding down the door and your acceptance letter awaits! Swoosh your wand and try your hand at Hogwarts subjects like Potions, Charms and Astronomy. Wands at the ready!

Potions – Disappearing Ink

Make your own Marauder’s Map – or any other sneakily secret message your heart desires – with this demo from Teach Beside Me (part of the We Are Teachers link roundup). All you need is laundry detergent, paper, and a black or UV light.

Phosphorescence is the secret to this magical mayhem! Chemicals called “optical brighteners” in the laundry detergent absorb low-energy yellow light and emit it as higher-energy blue light. With ordinary use, clothes seem whiter – but under a black light, the detergent burns with an unearthly fire! Become a Potions master today!

  • Acceptable: Send a secret message to a family member.
  • Exceeds Expectations: Combine regular and invisible ink for a sneakily misleading note.
  • Outstanding: Map out the best Easter Egg hiding locations in your yard.

Charms – Levitation

Wield awesome cosmic power and control the movement of objects from a distance using only the power of…. static electricity! Ever feel a spark when you touch a door handle, or watch a toddler’s hair stand on end after coming down a slide?

Static electricity is what we call the buildup of negatively charged, subatomic particles called electrons on the surface of objects. All objects have a modest positive or negative electric charge on their surface – and when there’s a big difference between two objects, watch out! ZAP!

Of course, as a wizard-in-training, you can use this knowledge for more than avoiding a really bad hair day. Move sticks, levitate plates, control bubbles and more!

  • W.O.M.B.A.T.: Rub a balloon on your head and giggle as it sticks to you.
  • O.W.L.: Make a pop can roll around at your command.
  • N.E.W.T.: Levitate that plate!

WINGARDIUM LEVIO-SAHHHH, RON: Click here for info, tips, and more!

Astronomy – Constellations

Did you know that Astronomy is a Muggle subject, too? You can totally get a head start on your Hogwarts courses by learning about star constellations now!

Ancient people were just like you – they wanted to understand the world they lived in. They studied the night sky and noticed that many of the bright lights moved in predictable patterns, while others seemed to stay put. We now know that the “moving lights” are actually planets, and tracking them helped to develop the first calendars. “Behind” the planets is the infinite universe, filled with far-off stars and galaxies. The unchanging position of these stars led storytellers to develop myths and names for certain groups of stars – including some groups very important to Harry Potter fans!

Best suited for younger Potterphiles, Royal Baloo gives a simple introduction to some of the constellations pertinent to the Harry Potter storylines.

  • First Year: Look for Polaris, the North Star, in the night sky.
  • Second Year: Try to find Sirius, Draco, and Lupus – the constellations, not the characters!
  • Third Year: Read up on other constellations visible from Holland in the spring – then go outside and try to find them!

Tinkering and storytelling unite as you build a moving machine, and transform light into art. Parents, be sure to check out the rest of the Exploratorium’s website. Make sure you’ve got some time set aside though – there are literally hundreds of STEM activities and explorations available. Now let’s get those busy brains working!

Activity 1: Cardboard Automata (ages 7+)

Auto-Mata. A-tomato? Aw-TAH-mata! However you say it, a cardboard automata is just a fancy way to describe a machine that moves independently. A moving machine? It lives! Run for your lives!

So are automata freaky robots, or fancy machines? Good question! The first automata alarmed and amazed people, who feared they were truly alive. Today’s robots spring from the dreams those historic automata inspired! Master the basic mechanisms, and let your imagination work hand-in-hand with your ingenuity.


  • Three in a Row: Can you master round-and-round, up-and-down, and back-and-forth motion by changing your cam structure?
  • The Storyteller: Illustrate a favorite scene from the books you’re binging using your automata.
  • Earth Day Guru: Let your recycling bin inspire design of your automata. Colors, patterns, texture, shape – how will different materials affect your design?

Activity 2: Light Painting (all ages)

Brushes, sponges, fingers….flashlights? You’ve never painted like this before! Explore light, color and movement over time while you make fabulous art. All you need is a digital camera, a light source, and a dark room! And the best part? Clean-up is a breeze!

READY TO EXPRESS YOURSELF? Info, tips and more here.

  • The Scavenger: How many different light sources can you use in your art? Think about lights on toys, remotes, watches, tablets – just get permission first!
  • Transformers: turn yourself into a butterfly, angel, alien or any other crazy creature.
  • Three’s Company: In the picture above, why don’t we see the motion of the girl’s arms? Who moved the lights? Who took the picture? Experiment with using more than one or two people to design your light painting!
