  • Equality and Inclusion in Nature Education

    Share
    Created: 1/11/2018      Updated: 1/15/2018

    Museum educator teaching in a Chicago classroom

    As we reflect on a day dedicated to a fearless and inclusive leader, I am reminded of all the insightful lessons Martin Luther King Jr. has gifted us through his words and actions. These lessons have the ability to resonate with many different elements of our lives.  

    For me, today reminds me of the importance of equality in nature access and environmental education. Regular access to nature, whether it is time outdoors in a park or prairie, sitting next to a lake, or hiking in the forest, is proven to offer many benefits from reducing stress and improving health to increasing creativity and improving children’s aptitude for problem solving that contributes to academic success. The more we learn about the benefits of regular connections and access to nature, the more critical it becomes to ensure equality of access.

    I strongly believe all children should have equal opportunities to experience the gifts and benefits of nature. Unfortunately, there remains a wide gap in equality to access for many children, especially minorities and those who live in cities.

    Our team at the Nature Museum is continually evaluating and extending our reach and offerings with a goal of getting deeper into more Chicago neighborhoods, especially those with diverse populations whose access to nature and environmental education may be limited.

    MLK’s activism was centered around the theme of justice. Today, I’m reflecting on the injustice of the continued diversity divide in nature access and education. It is my goal, and the collective work of our team here at the Nature Museum, to narrow that gap in Chicago by increasing inclusivity and access to nature for all.

    Everyone, especially children, deserve to experience the joys, peace and benefits that nature provides.

  • Feeling crazed? Nature offers antidote to hectic holidays

    Share
    Created: 12/20/2017      Updated: 1/5/2018

    Winter scene with candles in window

    As much as I love the holiday season, the constant hustle to juggle events, decorate, manage long to-do lists, and prepare for family gatherings can be overwhelming. So let me share an antidote, compliments of nature: Spend time outdoors in a few moments of stillness.

    Call it a nature “time out” or escape outdoors. Our family finds that time in nature, particularly in the quite of winter, is restorative and a time for reflection and connection.

    To me the rhythm of crunching snow underfoot helps me slow down and notice nature’s surprises, like the beauty of the stark trees in the winter cold. After spending some time outdoors, I feel restored and happier during a season that can feel exhausting.

    Let’s not use the excuse that “I don’t have time to stop for nature with so much to do.” A walk outdoors or even standing in your backyard looking at stars slows us down and gives us a quiet moment. Stillness can be energizing. 

    This Thursday is the Winter Solstice, the longest night (or, depending on your perspective, the shortest day) of the year. It is a perfect time to take a moment in nature -- in your backyard or park or forest preserve. 

    If you want to know more about the solstice, I’ve shared a few fun facts below. 

    Also, I would love for you to join us for a season celebration at the Nature Museum in our tradition of welcoming the new year at our Noon-Year’s Eve on Dec. 31, from 11:30am to 12:30pm. The Museum provides many nature moments both inside and outside for your family to enjoy.

    May you find joy in your season celebrations and in nature’s quiet gifts this holiday.       

    Facts about Chicago’s Winter Solstice:

    • Chicago will experience the Winter Solstice on Thursday, Dec. 21, at 10:27 a.m., when the Northern Hemisphere officially welcomes winter.
    • We will experience only 9 hours and 32 minutes of daylight that day.
    • At the same time, our friends in the Southern Hemisphere will celebrate the Summer Solstice.
    • Chicagoans who can’t wait for warm weather can be encouraged that we gain a minute or two of daytime each day beginning Dec. 22 as we march toward summer.

  • How do Clouds Float?

    Share
    Created: 11/30/2017      Updated: 12/5/2017

    In this series, we'll be addressing some common questions from visitors and readers. Do you have a science question that has you stumped? Ask our museum scientists via our form here and we'll answer it on our blog!

    Today's Question:

    How do clouds float?

    Clouds are made of water. Water is denser than air. Water doesn't float in the air. Therefore, clouds can't exist.

    Clearly, that’s not true. Clouds do exist, and they do float in the air. How? Why do clouds form? Do clouds fall to the ground? Why do clouds sometimes disappear?

    Clouds are created from water vapor that condenses into water droplets, and warm air and water vapor will rise above the cold air around it1. Your breath on a chilly winter day or the steam from a tea kettle are examples of water vapor that rises. Are clouds warmer than the surrounding air, and if so, what makes clouds warm?

    Clouds form when the sun creates warm, moist air by heating and evaporating water on the earth’s surface. The warm, moist air is less dense than the cold air above it, so that warm air rises2. The warm air cools as it comes into contact with the cooler air above. Cold air cannot hold as much moisture as warm air: the vapor has to condense into a liquid. This is the beginning of a cloud.

    The sun heats the earth, and causes water on the ground to evaporate3. The water rises, cools, and condenses. A cloud is formed!

    Clouds form when warm wet air rises and condenses in cold air. This explains why clouds exist, but now how do clouds stay in the air? Once the cloud forms in the cold air, why doesn't the cloud cool down and sink back to the ground?

    There are several reasons clouds float: first, the droplets in a cloud are small. Very small. An average water droplet in a cloud may only be 20 micrometers across4. That is half as wide as a typical human hair, and about the same size across as a particle of dust5. Even though dust is heavier than the air around it, a dust particle is so small that it can float in the air for a long time before falling. Water droplets in air behave the same way as dust6.

    The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat.

    Third, clouds stay warmer than the air around them because they absorb the sun’s energy better than the surrounding air7.

    Clouds don't float forever—if the surrounding air warms up, then the air is able to contain the cloud's moisture as vapor, and the cloud will disappear. And sometimes, the cloud becomes so large and moist that the water droplets in the cloud begin sticking to each other, and grow bigger and bigger. The water droplets become so big that they no longer behave like dust particles. The droplets begin to fall. If you look up at this kind of cloud, your face will be wet: those droplets are now called "rain" and you really ought to go inside.

    This map shows how much cloud has fallen to the ground in 2017. More green means more rain8.

  • Our Gratitude for Nature’s Connection

    Share
    Created: 11/21/2017      Updated: 11/22/2017

    I’m never more grateful for the gifts of nature than during the approach to the Thanksgiving holiday.

    Our Midwest Thanksgivings are accentuated by the profound season change to autumn, featuring abundant harvests, wildlife preparing for winter and leaves changing color then dropping along with the temperature. The holiday brings our relationships into focus through nature’s lens and through family gatherings.

    Anticipating family time and pausing to express gratitude for one another and our blessings affirms our feelings of connectedness. In our family, it also affirms a connection to nature. Even with our children now all adults, our family gatherings and adventures usually find us outdoors in nature -- playing, exploring, watching, reflecting, or running in a Turkey Trot. It just feels good to be outdoors.

    Our Thanksgiving celebration and meal is generally followed by a stroll outdoors, much as we did when I was growing up in Chicago’s west side where my police officer father connected to nature through his garden. He loved growing and harvesting the vegetables, and faithfully prepared the soil for its dormant, winter rest. He did so with appreciation and anticipation of spring planting.    

    Wherever you spend the holiday, a nature connection is not far away. Take a stroll outdoors. You may be rewarded by hearing the distinctive trill of sandhill cranes on their migration south. This week is expected to be the peak time for these large, highflyers to pass over Chicago. Many other birds, such as robins, are gathering in groups in preparation to migrate or are busy eating as many berries as seeds as possible to “bulk up” for winter.

    Notice nature. For example, watch squirrels scurrying around lawns and parks, busily stocking up on fallen seeds and nuts. Pause to notice the trees in your neighborhood. Most are nearly leafless and reveal the tangles of branches and limbs reaching skyward. Watch and listen with appreciation for nature’s stories.

    Like the connections we foster with our family and friends by spending time together, our connection to nature grows stronger through the time we spend in it.

    May you and your family deepen your connections and share in the abundance of nature’s gifts that we gratefully share. Happy Thanksgiving.

  • How do Cicadas Make Sound?

    Share
    Created: 8/25/2017      Updated: 8/25/2017

    In this series, we'll be addressing some common questions from visitors and readers. Do you have a science question that has you stumped? Ask our museum scientists via our form here and we'll answer it on our blog!

    Today's Question:

    How do cicadas make sound?

    …and how are they so loud? Cicadas are the song of summer across the United States, Chicago included. Even just two miles from downtown the droning of cicadas in trees can be downright overwhelming in July and August afternoons. But cicadas are so small: how do they make such a powerful sound? With no vocal chords, no lungs, and no subwoofer it ought to be impossible to hear a cicada from a mile away and yet, it's not. The loudest cicadas can emit a sound at over 100 decibels[1], which can be heard over a mile and a half away.[2]

    If you suspect that cicadas make sound the same way that the cricket, that other noisy summer insect, does then you'd get points for effort, but no points for being correct. Crickets make sound by rubbing their wings together (not its legs!), and cicadas have a special organ called a tymbal that produces sound. The tymbal contains a series of ribs that buckle one after the other when the cicada flexes its muscles. Every time a rib buckles, the rib produces a click.[3] Many clicks produce a buzzing sound. The action is like how a bendy straw makes sound: pulling and pushing the ribs of the bendy straw together makes a series of clicks. If you could push, pull, and twist a bendy straw hundreds of times a second the sound of the clicks would be so close together that you'd only hear a buzzing sound: this is how fast the cicada is able to vibrate its tymbal.

    Chicagoans can hear several different species of cicada in the summer: the dog-day cicada, the Linne's cicada and the scissor-grinder cicada are all common.[4] In fact, the author heard all three of these cicada calls through his window while writing this post. Click on the links above to hear the sound for each cicada and to learn more about each of these species.

    And yes, some online sources will tell you that it's possible for a cicada to damage your hearing. This is technically true and at the same time, there’s no reason to worry. The very loudest cicada, at 108 decibels[1], would permanently damage your hearing if you held it up to your ear for two minutes straight.[5] Chicago cicadas are not even close to being that loud. Even if we estimate them at 90 decibels, as loud as a motorcycle from 25 feet away, it would take 8 hours of continuous play time for it to damage your hearing. Cicadas are completely, absolutely harmless. Just loud. Very loud.

  • Priority Species Update: A Museum Full of Smooth Greensnakes

    Allison Sacerdote-Velat holding an adult Smooth Greensnake

    Curator of Herpetology Allison Sacerdote-Velat has spent much of her summer working with one of our priority species - the Smooth Greensnake. Allison and her team have been surveying for Smooth Greensnakes in sites in several counties in Illinois, but took a break to give us a quick update on teh work they've done so far and the work that's still ahead.

    We have been surveying for Smooth Greensnakes in sites in Lake, DuPage, Cook, DeKalb, and Grundy Counties. Some sites are part of a long-term population monitoring study and some are previous release sites for headstarted snakes.

    Smooth Greensnake hatchlings emerging from eggs

    When we headstart Smooth Greensnakes, we can focus on improving two aspects of their survival; hatching success of eggs and hatchling overwintering survival. In DuPage County, we are improving hatching success by incubating half of the eggs from nests that we find in the field at our Forest Preserve District of DuPage County's partner facility, Willowbrook Wildlife Center. Once the eggs hatch, we measure, mark, and release the hatchlings back to their nest sites. By individually marking hatchlings, we hope to find them again next season to improve estimates of hatchling overwintering survival.

    Meanwhile, we monitor the fates of the remaining eggs in the field to determine wild hatching rates. In partnership with Lake County Forest Preserve District, we are using the second headstarting strategy, improving both hatching success and hatchling survival by caring for the hatchling Smooth Greensnakes until next summer. We aim to improve their chances of surviving that critical first year, by keeping them safe from predators until they are larger, and increasing their body size so they are better able to survive winter and produce more young once they are released.

    Smooth Greensnake hatchlings in the Nature Museum lab

    This season, we have incubated, hatched, marked, and released snakes from 75 eggs in DuPage County, and we are currently headstarting 81 hatchlings from Lake County at Peggy Notebaert Nature Museum.

  • What is the Fastest Turtle?

    Share
    Created: 6/21/2017      Updated: 6/21/2017

    In this series, we'll be addressing some common questions from visitors and readers. Do you have a science question that has you stumped? Ask our museum scientists via our form here and we'll answer it on our blog!

    Today's Question:

    What is the fastest turtle?

    Turtles: they're not renowned for their speed. Sure, the turtle** wins in The Tortoise and the Hare, but just to serve as a humiliating example of arrogance. No one celebrates for the tortoise in that story, you know? It's ok, though. Turtles don't mind! There's no need to be fast when you carry your own armor for defense and your food is stationary.

    But surely there is at least one turtle that's massively mobile. A turtle with wheels. A turbo turtle. Which turtle is it? Can any turtle outrun a human? What is the fastest a turtle can go?

    We begin with the official recordkeepers. The Guinness Book of World Records maintains the record for fastest tortoise: the tortoise ran at an average speed of 0.63 miles per hour.[1] Tortoises are notoriously slow, however, even for turtles. We can do better.

    Some turtles can "sprint" much faster than any tortoise. Compare the Guinness World Record tortoise video[2] against any number of Youtube "fastest turtle" videos to see soft-shelled turtles rushing to safety (gee, what incentive would a soft-shelled turtle have to be able to move quickly?). From one of these "fastest turtle" videos, I estimated the speed of a sprinting turtle based on the distance it ran (about 15 feet), divided by the time it took to move that distance (about 3 seconds). From that quick calculation, soft-shelled turtles can move at a speed of 3 miles per hour. For comparison, that's a comfortable walking pace for an adult human.

    That's not the fastest turtle, though: turtles swim much faster than they can walk, and the blog post's question didn't specify how the fastest turtle was getting around. The leatherback sea turtle is reported as being able to swim up to 22 miles per hour, though I could not find an original source for that claim.[3]

    We're not done yet: turtles have moved at least 1,000 times faster than even the fastest sea turtle.

    Animals have been launched into space many times to test the effects of space on living things.[4] Turtles have had their share of space flights: turtles have been sent into low-earth orbit by Soviet (Soyuz 20) and Iranian (Kavoshgar-3) space missions. All turtles survived both missions. To maintain low-earth orbit, the turtles traveled at 17,000 miles per hour.[5] 

    But the fastest turtles ever, and the ones who have been farthest from earth, are two Russian tortoises that were launched aboard the Zond 5 spacecraft in 1968. This spacecraft traveled to the moon (it didn't land, of course: humans are the only animal that has stepped onto the moon) and returned safely to earth. Details about the speed of this flight are difficult to find.

    Proton-K rocket

    This Proton-K rocket launched the Zond spacecraft. Not pictured: two intrepid tortoises.[6]

    However, NASA used a similar flight plan during the Apollo missions, and those flights reached speeds of 23,000 miles per hour.[7] It is fair to conclude that the Zond 5 spacecraft and those two Russian tortoises reached a similar speed! Leatherback turtles travel over 10,000 miles during their migrations.[8] If a leatherback turtle could swim its maximum speed without stopping, it would complete that trip in 19 days. A rocket-propelled turtle covers that distance in 25 minutes.

    And that, without a doubt, is the fastest a turtle has ever traveled.

    Created: 6/13/2017      Updated: 6/16/2017

    Statement by Deborah Lahey, President and CEO of the Chicago Academy of Sciences/Peggy Notebaert Nature Museum regarding the United States announcement to withdraw from the Paris Climate Agreement.

    There is an undeniable correlation between the health of our planet and the health of all living things. That fact is what makes the United States’ announcement withdrawing from the Paris Climate Agreement a concern to many people. The action could erode the collective, global efforts needed to provide solutions to climate change as well as other collaborations. Our world needs every leading country working together for the good of all living things.

    The Chicago Academy of Sciences / Peggy Notebaert Nature Museum is deeply committed to fact-based, environmental research and education, and we advocate for uniting global and local efforts to protect our planet and nature. Through our collection and ongoing research, we have documented 160 years of history of the environmental changes in our region and continue to contribute to science-based learning.

    On a more personal and individual level, the Nature Museum is building a deeper connection between nature and the public. Every day, we provide a welcoming gateway for people to better understand our urban environment and what it means to them. Through engaging exhibit experiences and programs, including the self-produced exhibit Our House: Rethinking Home in a Changing Climate, people are encouraged to think about how our choices -- from building homes to driving cars – can be in harmony with nature, or not.

    Our region is fortunate that Chicago Mayor Rahm Emanuel announced in response to the U.S. decision that the City of Chicago will continue forward “to achieve goals set in the Paris deal.”  Many regional business and civic leaders also are publicly stating their support for the country to stay in the agreement. This leadership will help Chicago to continue making progress reducing carbon emissions in line with the international climate accord.

    We believe it is critical for everyone to stay informed and united in efforts to address climate change. To increase our contributions to these efforts, the Nature Museum plans to convene more forums with organizations, policy officials, municipalities, thought leaders, and individuals to dialogue about reducing greenhouse gas emissions and pursuing innovative clean energy sources that are good for the environment and create new jobs.

    Be assured that our teams of scientists and educators are working to build greater public understanding and engagement in climate and environmental issues. We know that unity makes us strong, and collectively we can protect the environment on which all living things, including each of us, depend -- now and in the future.
