Poem of the Week

“Knee-deep in June”

James Whitcomb Riley (1849–1916)

I. TELL you what I like the best—
’Long about knee-deep in June,
’Bout the time strawberries melts
On the vines—some afternoon
Like to jes’ git out and rest,	5
And not work at nothin’ else!

Seven Quick Takes: Great Book Combos, Cake Fails, and Shark Teeth

 1.  My friend Bill pointed out that you rarely see The Agony and the Ecstasy and Electronics for the Evil Genius on the same shelf.  I suppose he's right. 

I feel like there's something about this book shelf that encapsulates my life.

Big Enough

2 .  I am always on the look out for spots with poor drainage so that when we get a few days of rain we can have a Ducky Day.

This involves putting on rubber boots and hunting down the biggest puddle we can find... After a thorough soaking, we head home for baths, popcorn and hot chocolate!

We started this when Mxyl and Klenda were toddlers, but if you get a big enough puddle, everyone still wants to play!


3. Joy!  Rapturous delight!  This year I used my birthday money to buy a tree peony!  This is a long term investment, but, over the next 50 or so years this graceful plant will get about 6 feet high and 8 feet wide with progressively larger flowers.

This year I get three blossoms this size (8 inches of petals that look like they are cut from iridescent purple silk).

 4. Have you ever made something you were sure was going to be wonderful, and right about the time you are finishing, you suddenly realize...

That it's a terrifyingly creepy dinosaur cake that looks like it's planning to eat your head?

Yeah.  I know. We all go through that.

Fortunately the cake was for Choclo, and he declared it his favorite cake ever.

Trekking to the beach at Purse Park

 5.  It's shark tooth season!  We live in Maryland, in a spot that was covered with a shark infested sea (30 million years ago).  Yes, some people probably would try not to think about that too much.  But we find this wonderful: since each shark has thousands of teeth throughout it's life, our soil is embedded with millions of fossil teeth!

From Bayfront Beach

Fortunately, we don't have to dig for them.  They are continually washed out of the soil and found on the banks of rivers and the Chesapeake Bay.

Which means, on pleasant spring days, we spend the day at the beach,  playing in the sand and enjoying the water collecting fossils.

These are teeth, ray plates, and bone fragments (from whales and dolphins) from our latest day off scientific expedition.

If you're wondering why this is seasonal, I have two words for you: jelly and fish.

6. We finished our model rockets this week! We will meet one more time on Sunday to launch at NASA Goddard (I really do love saying that!) and we are done with our Astronomy and Rocket classes.  Hooray!  So fun!


7. If you are wondering what happened to The Big Trip, we are still traveling in Japan, although we will be leaving soon for Mongolia.  Blog posts coming soon, I promise.  We just got snowed under with birthdays, anniversaries, and end of year craziness.

If you are wondering what the heck that's about, the short answer is that we came across a truly enormous pile of imaginary money, and we have been using it to take a once in a life time trip around the world.  You're free to join us, and/or if you live someplace we will, or should be going, to have us "stay" with you!

Happy weekend!  More fun with Jen!

Guest Blog by Klenda: LOTS of shark teeth

We went to the bay and found a few more more shark teeth than usual (Hercules uses litotes) . We were starting to wonder why none of the other Adventurers had come, because they had said that they would, when a truckload of assorted children and moms arrived...

The moms, most with 5+ kids.

playing in the shallows.

We saw a horseshoe crab couple laying eggs (I don't think we took a picture, sorry) and two ducks. Choclo announced, "I got REALLY close to the ducks, and they didn't even bite me or hurt me!"

Trying not to get soaked.

So many shark teeth that we're buried beneath!

We eldest kids tried to escape from the middle school kids, who had gotten into a massive water fight, by wading way out.

We couldn't. Escape.

 In fact, we all got much wetter then expected.

Not that that's a bad thing.

And this was the accumulated work of 2 or 3 hours of hunting.
Why, yes, this is only what the seven of us found, not counting the other families. Why do you ask?

Guest Blog by Mxyl: Videos of Our Trip!

Hello, everyone!  On our trip discovering the world (although you'd think, being on this planet for 7 years, we'd already know something) we've shown you pictures, written blog posts, and described in detail where we've gone, and even showed you some videos of the trip and attractions.  There's one thing, however, that you have yet to see: us!

Here, recorded in stunning Super HD, is one and a half minutes of digitally remastered, optically digitized, full-fledged, spectacular, Han-shot-first amazingness of Zorg, Klenda and my reactions to Australia:

Allllright.  So maybe I exaggerated a bit. 

Anyway, I'm pretty sure we've forgotten someone else: our most hammy actor, Oob!  Here he is in Hawaii in an even more spectacular video!!


Lots of thanks to Ms. Anabelle for the leis and other Hawaiian things!

More Memorial Day

 Every Memorial Day I look through my garden to find flowers to decorate the family graves. 

I like to get them from here, because this was the garden where my father-in-law planted his roses.

This is a house where extended family gathered, and many of these plants were seen by those whose graves they will decorate.

It's a living memory.


Usually, Memorial Day comes around, hot and muggy, and the garden is in a lull between the last of the late spring and the first of the summer flowers. I have to search for the last of the roses.

Not this year!  Thanks to a cold winter and a cool spring, we are in the peak of roses and irises, and all manner of flowers!

This year, the bouquets practically make themselves: red and white roses with salvia for Aunt Toni, the wonderful woman who first made me feel really welcome to the family.

Irises and roses for my father in law, Grandpop Bob, who died before I met him,but whose life and virtues I enjoy every day in my husband.

Dark purple irises for his younger brother.

Old fashioned pinks, geraniums and white roses for his mom, and azaleas for his dad.

 The family gathers, and off we go, caravanning to first one cemetery, then another.

We've all brought flowers, and we have fun arranging them for each person just so.

We tell stories.  We talk about how much each person would have enjoyed their flowers.  Probably do enjoy the fact that we are coming out the way they did...

 We enjoy our time together as a family.

The kids pick up the fallen petals and arrange them in patterns on the headstones.

We pray for our departed dear ones.

We smile and head for home, time for a big cookout, time for more togetherness, more stories. 

The weather is perfect: sunny, 72 with a light breeze.

This year the kids promised to put on a play for us, and it turned into many, many plays, most of them based on Aesop's fables.

Grandpop Bob would have liked that.  Maybe he did!

Happy Memorial Day!

Poem of the Week: Memorial Day

Long before Memorial Day was celebrated with cook outs, it was celebrated by visiting the graves of veterans and decorating them with flowers.  Back then it was called Decoration Day.  Since we have many veterans in our family, we continue to decorate the graves, and then we go home and have a big family cook out!

Decoration Day
By: Henry Wadsworth Longfellow

Sleep, comrades, sleep and rest
  On this Field of the Grounded Arms,
Where foes no more molest,
  Nor sentry's shot alarms!

Ye have slept on the ground before,
  And started to your feet
At the cannon's sudden roar,
  Or the drum's redoubling beat.

But in this camp of Death
  No sound your slumber breaks;
Here is no fevered breath,
  No wound that bleeds and aches.

All is repose and peace,
  Untrampled lies the sod;
The shouts of battle cease,
  It is the Truce of God!

Rest, comrades, rest and sleep!
  The thoughts of men shall be
As sentinels to keep
  Your rest from danger free.

Your silent tents of green
  We deck with fragrant flowers;
Yours has the suffering been,
  The memory shall be ours.

Other Stuff Going On

 I had a birthday!  I actually spent my birthday visiting my  mom and dad up in NJ with Zorg.

Here are Mom and Zorg bringing in my cake with 44 lit candles!!

Yes, I did blow them all out.

No, the fire department did not help.

It was the cutest cake, too!  When they showed it to me, I thought they had gotten me a porcelain flower knick knack, but no,that clay is all frosting!

 We were also celebrating my mom's birthday, and Mother's Day, so it was all pretty festive.  I prepared and planted a garden for my mom, so she'll have something nice when I'm not there.  It was a really nice visit, and I'm so glad Zorg got to spend the time with my folks!

We also got to visit an amazing playground!  I would love to play on an adult sized one of these!  If you are ever in Andover, NJ on a non-school day, their school playground is fantastic!

And, when we got home, Klenda had made me another lovely cake!

And the Zoomlians had gotten me an array of awesomeness unlikely to be equalled to the ending of the world!  Hyperbole, you say? Not so.

They got me two things I've wanted for a long time: the SHIELD Helicarrier and a Jaeger!!

I have them hanging over my desk, so you can see that the Helicarrier won't actually solve all my parking problems in the way I had envisioned, BUT,  I'm using the Helicarrier as the drop vehicle for my Jaeger.  If you are not blown away by how incredibly awesome this actually is, clearly you have not seen Avengers and Pacific Rim.

At least not as many times as I have.

Kids' Rocket Science: Third Law of Motion

 The third law is the one everyone remembers: for every action there is an equal and opposite reaction.

The favorite demonstration of this is the Newton's Cradle.  Perfectly equal and opposite reactions!


Having done this lesson a number of times, here is my advice: yes, you need a Newton's Cradle; no, you can't make one yourself; yes, you will need a new one each time because the kids will play with it until they tangle the lines irretrievably.  The good news is that it's less than $10 counting shipping. Do not take it out of the box until just before class time.

An interesting  part of the equal and opposite law is what I think of as the "billiards corollary" because this is how professional pool sharks actually make their shots.  When a ball strikes another object, it bounces off with equal force (minus whatever was absorbed by the object) in the exact opposite direction (at the opposite angle).  Lacking a pool table, we showed  this by rolling golf balls against the wall at different angles.

It's easy to see how this law works when things are moving, but most every day encounters with it are fairly static: when you sit down on a chair, you are pushing down on the chair with your entire weight, say, 100 lbs. The chair is pushing back 100 pounds. One kid asked what happened if the chair didn't push back, the answer is that if the chair can't push back enough, it breaks and I fall on the floor, which hopefully can still push back enough!

My favorite way of looking at this law is by having two kids (of roughly equal mass) stand on skateboards and push each other.  Lacking skateboards, I had them take turns standing in our wagon and pushing against me. Of course, as hard as they pushed, they moved away!

That led to a conversation about recoil: cannons, guns, baseball bats, and so forth.

 Then it was time to make the Alka-Seltzer rockets.  When I was setting up the class, I ran a few test flights to make sure that my Alka-Seltzer tablets were still good.

The good news was that the tablets were fine.



The bad news was that some of my old film canisters (which I had successfully used for this the last four times I ran this class) were no longer holding pressure. 

 Worse news: during the actual class, all the canisters, even the ones that had worked for the tests failed.  The farthest a rocket got was 6 inches off the ground! Usually we can get 20 feet in the air!

What a disappointment.

 

So I decided to do some tea rockets instead! 


Not a perfect demonstration of the third law, but much more satisfying!


 And I could use the left over tea to serve the class tea and strawberries!

Kids' Rocket Science: Second Law of Motion

 The Second Law is probably the hardest to explain to young kids: F=ma.  Force is equal to mass times acceleration.  I like to put it as: "The heavier it is, the harder it is to push.", and "The harder you push the farther it goes."

The fact is, it's more specific than that.  If push something exactly twice as hard, it goes exactly twice as far.  If something is exactly half the mass of the first thing, it will go exactly twice as far, all other things being equal.

 We looked at this several ways.  I used a very light ball, and a sand filled ball that happened to be a similar size, and tried tossing them. This is good because it confirms their everyday understanding that, yeah, you have to use more force to throw a heavier ball. Naturally, any boys in the class will try to throw the heavy ball as far as possible, but, in my view, that's okay- they can feel the extra effort it takes to heave the extra mass.

Then we tried dropping the two balls in the sand box.  This was actually a better experiment because you could easily see the dents left behind by the two balls (the heavier ball left a deeper dent because it fell with more force, while the acceleration of gravity was constant)

We also rolled real golf balls and foam golf balls (you could use ping pong balls) down an incline and saw that the more massive balls rolled farther. Again, this is somewhat more useful than throwing because the gravitational acceleration is constant when you use gravity.

It also explains why, in the Pinewood Derby, you are not allowed to have your car weigh more (have more mass) than a certain standard.  It would be an unfair advantage because the heavier cars would always win.

Now, I did say these rules applied with all other things being equal... Such circumstances are pretty rare on Earth.  A baseball hit with twice as much force won't actually go twice as far.  Why not?  One reason is that it will have gravity pulling on it for a longer  time since it will be in the air a longer time. Another reason is that it has to travel through more air, and therefore more air resistance.

Ah, air resistance.  That's pretty important when you're talking about rockets.  How far can you throw a piece of paper?

Try throwing a plain flat sheet of paper as hard as you can.  It's pretty hilarious, actually.  One of the kids immediately suggested that we wad it up into a ball.  That went much farther, even though it was the same mass as the flat sheet.  Then I folded a sheet into a paper airplane, and that went clear across the room and pegged Zorg.  Sorry, Zorg!

 We made Puff Rockets from this printable pattern.  They are designed to have a very low mass, as well as minimal air resistance, and they go remarkably far on a puff of air (provided by you!).

You can also experiment with flying them with and without the fin assembly.  It really lets the kids discover for themselves why rockets have fins.

 Super fun!  Thank you Mxyl for the pictures!

Happy Anniversary!

 24 years! 

Can you believe it?!

Still smiling.

Still cracking each other up nearly a quarter of a century later...

So happy we got to get married young (we were both 20)!

So glad we get to grow old(er) together!
