Belle's Journey

At the end of August, I headed out with a passionate osprey-watcher to check on a nest near Cayuga Lake. It was atop a high pole, on a platform built for ospreys who, the locals hoped, might repopulate the area.

Mother (Ophelia) and daughter were there, calling loudly for dad to bring home the fish. "I figured mom would have left already," said my osprey buddy. With the youngest able to fly and learning to hunt, there was nothing left to do - and dad ospreys are the ones who stick around until the last fledge is ready to live independently.

Osprey are hawks. Big hawks who thrive on fish. Some folks refer to them as fish hawks. They hang out in upstate NY, and in the northeast for the summer and, when fall comes, they fly to South America.

A lot of what we know about ospreys comes from researchers like Rob Bierregaard, who has been tagging young ospreys with radio transmitters and following their migratory paths. One of the cool things he discovered is that young ospreys - at least those on the east coast - tend to make their initial southbound journey over the ocean.

Five years ago Dr. B (as his students call him) was waiting for a young osprey to return to its nest so he could fit it with a backpack radio transmitter. A neighbor, seeing him there, suggested he write a book. So he did.

Belle's Journey, An Osprey Takes Flight

The story of Belle begins with her parents, who return to their nest on Martha's Vineyard in March (brrrr!), and the two scientists who are scouting for active nests. By the middle of July, the young ospreys are nearly as big as their parents and they're stretching their wings. One day, while the birds are out hunting, Dr. B and his fellow researcher climb up and put a fish in the nest as bait. Then they cover the nest with wire mesh to trap the birds.

Success! They capture Belle, fit the backpack straps over her wings and sew the harness so the radio transmitter won't fall off in flight. The transmitter will send signals so the scientists can track her migration.

So here's the thing about a young osprey's first migratory flight: they don't have maps. Their parents have already gone, so there's no flock to join. They may run into danger, such as hurricanes, eagles,  or people who shoot at them. And the journey is long - three to four thousand miles.

What I like about this book: The story is written from Belle's point of view. We see her adventures during migration through her eyes. Chapters about the scientists are written from a different point of view. I like the back matter that gives more information about ospreys, migration, and what to do if you find injured birds. There are also lots of resources.

And I love the illustrations! Full color spreads are soft and inviting. Sepia-colored vignettes give us quick glimpses into the lives of Belle and the children following her journey. There's even a series of sketches illustrating how an osprey captures fish.

Spooked! Blog Tour and Author Interview

Spooked! How a Radio Broadcast and the War of the Worlds Sparked the 1938 Invasion of America
by Gail Jarrow
144 pages; ages 10 - 12
Calkins Creek, 2018

Mischief night is October 30, the night before Halloween. It's the night when older kids and teens head out to soap windows, TP trees, and other mischief. But on October 30, 1938, a radio theater company unwittingly perpetrated mischief on a national audience. They performed an updated production of H.G. Wells's science fiction novel, The War of the Worlds.

The novel portrays a martian attack on Earth - unrealistic, right? And yet, people tuning in late heard breathless announcers read alerts of an invasion. Because they hadn't heard the disclaimer at the beginning of the show, that this was an act of fiction, some people panicked. They piled in their cars and fled their homes. Others jammed phone lines, calling relatives for one last conversation. And some drove to the invasion site, hoping to get a look at the alien invaders.

 How could people be so taken in by a radio show? It was the depths of the depression, Gail Jarrow writes. Hitler is rising to power, and his invasions of European countries have Americans anxious. So if a person turned on the radio after the introduction, they might believe that the "program interruptions" they heard were legitimate alerts about invasions on American soil. Like the best propaganda and fake news, the radio drama contained just enough truth to make it believable.

This is a story of historical events, so why am I reviewing it on my blog? Because there are STEM connections. Fortunately, Gail had time to answer Three Questions.

Archimedes: How does the history connect with science, technology, engineering, and math?

Gail: I'm hoping that kids will think about the history of technology in communication. Right now, we live in a world where the technology - social media - is way ahead of human behavior and culture. Just look at the Internet. Back in 1938, that's what was going on with radio. People got their entertainment and news from the radio. As I studied this event in history, I kept seeing parallels in the way people responded to a radio broadcast and the way people respond to social media now. The biggest issue is confirmation bias (that we tend to believe "news" that conforms to our ideology or politics).

Not only is this a hazard when reading news presented on our social media, but it can also sway scientists, says Gail.

Archimedes: Most scientists try to avoid bias. So how would it affect their research?

Gail: Some researchers might be too quick to dismiss an outlier - data or observations that are different from what they expect - and label it as a mistake or sample contamination. Instead, they need to look carefully to see what is going on. People could have easily checked whether there was an invasion by turning their radio dial to see whether other stations were reporting the same breaking news. Some people did that, and even called local police or CBS. But too many people assumed that what they heard was the truth.

Even more interesting, the researchers from Princeton who studied the "panic" fell victim to confirmation bias, and their study has serious flaws. They relied on interviews from people who lived near where the invasion was purported to happen instead of interviewing people across the country. Their sample size was too small to extrapolate meaningful results for six million people, and they relied on poor statistics. To compound the problem, editors of textbooks didn't read the published study carefully, and included it in textbooks.

Archimedes: I can see how kids might be exposed to "fake news" and confirmation bias in history and social studies. But science?

Gail: Sure. Think about kids doing a lab - especially when it's a lab that has been done year after year, and they know the range of results they're expected to get. So if they get data that doesn't conform to what most people get, they think they've done something wrong. It's tempting to toss the data that doesn't fit the hypothesis - but that's not the right way to do science. Instead, they should include it - and so should scientists doing research. Students should read about our mistakes.

We ended our conversation with a discussion about how important it is to read news from a variety of sources - to boldly turn the dial (or click the channel-changer on the remote) to a different station in order to verify what we hear. And, if we can't verify a report, then refrain from posting it or sharing it.

"I hope young people will really think about the things they hear, ask good questions, and use their critical thinking skills," Gail says.She is currently at work on her next book, Poison Eaters about fighting danger and fraud in our food and drugs.

Wednesday Explorers Club ~ Soccer ball science


Recreational soccer is in full swing now. So are the local school teams. And after a fantastic World Cup season, some kids have soccer on the brain. So now's as good a time as any to indulge in some soccer science.


 First, you need a soccer ball - and some others: a volleyball, basketball, and even a similar-sized beach ball. 

Now let's compare bounciness. Find a hard surface (a sidewalk, parking lot, or tennis court) for a bounce test. Hmmm - we need a way to measure how high balls bounce. how about taping a couple yard-sticks or tape measure to a fence, wall, or tree?

Testing time: Drop each kind of ball from a height of three feet and write down how high it bounces. Then, stand on a stool (or ask a really tall person) and drop each ball from six feet. Write down how high they bounce. Remember to do each bounce test three times so you get a fair idea of bounce height for each kind of ball. 

What do you notice?

So, if you're like my kids, you play soccer anywhere you have space: the back yard, school soccer field, packed earth driveway.... How does ball bounciness change with the playing surface? Try the bounce experiment on different surfaces. How does tall grass compare with mowed lawn? How does packed earth compare with a sandy surface?

OK - water break is over. Time to get back to the game!
