Homeschool Voyager's Weather Report


In wrapping up our weather studies, we wanted to come up with an activity to sort of tie it all together. And I think we did!

First, we had the little voyagers watch a few weather reports on youtube, to get an idea of what they involve -- including some funny ones -- or bloopers.

Next, we talked about our current weather, made predictions, and checked the local weather forecast on the internet. (weather.com)

After we decided on what the report should include, we worked the the little voyagers on the script. 

Since this was their first real video report, we tried to keep it simple, and give each little voyager a role in the broadcast.

Weather in San Diego can be pretty boring sometimes, but on this day, Mother Nature was on our side, and even provided us with some rain! 


Enjoy our video!

If you are also studying the weather, we would love to see some student weather reports from around the United States. Please leave us a link in the comments or email us and we will post your video here, too!

The Great American Bird Count is for Kids!

 There are lots of good resources to make this a fun and educational activity for everyone.

You can download this printable pdf - Guide to Common Birds --



And this one (pdf or word doc)  for keeping track of your bird count.

 *   *   *
eBird has a great tutorial on how to count birds. This would be a great math activity to practice estimating objects. 

*   *   *
Cornell has some really awesome videos, like this one:


This is the Spoon-billed Sandpiper on her/his nest, and her babies!
Definitely worth watching with your kids -- fascinating and educational.

Why her and his? What the video and listen to the video for the answer!

*     *     *     *     *

One more thing -- Participants in the Great Backyard Bird Count can win PRIZES!
Be sure to check it out -- They are giving away some nice bird-related items.

*     *     *
I'll have more bird resources in the future, so if that is something you and your children are interested in, be sure to check back!

So long, for now -- Gotta fly!

Weather Proverbs


The other day, Rosetta was telling me about the weather proverb she heard at bible study, and how there was a similar saying in the bible. That gave me the idea to do a post with lots of proverbs to go with our weather unit.  First, the one Rosetta mentioned:

Image from Roger1952 on flickr

The following explanation is from the Weather Dude:
People have been forecasting the weather for centuries. They once looked to plants and animals for hints about what the weather would do. For example, before it rained, some people often observed that ants moved to higher ground, cows lay down, pine cones opened up, frogs croaked more frequently, and sheeps' wool uncurled. Over the years, people began to notice other natural clues to upcoming weather, and several weather "sayings" grew up over the years.

When looking at weather proverbs, keep this in mind: They are usually based on someone’s observations and not on scientific studies. Because climates and weather patterns differ throughout the world, a weather proverb based on observations in one location may not be valid in another location. Some proverbs arose simply from coincidence, not weather patterns, and therefore may seldom hold true. But under certain circumstances, some proverbs do hold up to science. Here are some that, under the right circumstances, have proven valid. 

"Red Sky at night, sailor's delight.  Red sky in the morning, sailor take warning."
The explanation - Why the Red Sky: 
When the western sky is especially clear, there is often a red sunset. That's because as the sun sets, its light shines through much more of the lower atmosphere, which contains dust, salt, smoke and pollution. These particles scatter away some of the shorter wavelengths of light (the violets and blues), leaving only the longer wavelengths (the oranges and reds.) If an area of high air pressure is present, the air sinks. This sinking air holds air contaminants near the earth, making the sunset even redder than usual. This would be the “red sky at night.” In the middle latitudes of the northern hemisphere, weather systems most often approach from the west. Since high pressure generally brings fair weather, this type of red sky at sunset would indicate that clear weather is approaching, which would "delight" a sailor. If the sky is red in the eastern morning sky for the same reasons as above, then the high pressure region has most likely already passed from west to the east, and an area of low pressure may follow. Low pressure usually brings clouds, rain or storms, a warning for sailors.
Now for a random selection of weather proverbs:

The Water Cycle: Facts, Poetry, Songs and Stories

Still image of an excellent interactive diagram from earthguide.ucsd.edu

This sequence of lessons was published by MacMillan Company in 1908. I like that it teaches a scientific concept -- across curriculum. Sure, there are the facts, even the experiments, which are super! But there is also poetry, which invites visualization, descriptive writing, vocabulary building, and making connections - to the child's world.
RAIN
An Exercise in Explanation

Under the influence of heat, water evaporates; that is to say, it passes into the air in the form of vapor. This vapor is invisible. If you leave water in an open dish, within a few days, especially if the air is warm, the water will be gone. You could not see the water passing off, and yet it has evaporated. When water is boiling in a tea kettle, you can see no steam close to the spout, but just as soon as this steam comes into contact with the colder air outside it becomes visible.

In the same way the heat of the sun causes constant evaporation from the surface of all water, and even from the surface of all land that contains moisture. This moisture is lighter than the air, and therefore is constantly rising. In this way water is all the time being drawn up into the air in the form of vapor, and when this vapor gets into the colder regions high above the land, it condenses into visible masses which we call clouds.

Now what causes rain? If you hold a cold plate in front of the steam coming out of a kettle, the steam will condense in little particles of water, and these particles will unite into drops which will run down the plate. In the same way when a cold wind strikes the fine particles of water in a cloud, these particles unite and form drops which, being heavier than the air. fall to the ground as rain.

1. What is explained in the first paragraph? What in the second? What in the third?

2. Learn the meaning of evaporate, invisible, contact, visible, moisture, condense, masses, particles.

3. Perform and report the experiments suggested.

4. Learn other facts about rain, and talk them over in class. Without the help of your book, write three or four paragraphs on the subject.

5. Look up and tell a story about James Watt.


Water Cycle Vocabulary Flash Cards - Created at Printable Flash Cards
A Study of Poetic Pictures

We knew it would rain, for all the morn,
A spirit on slender ropes of mist
Was lowering its golden buckets down
Into the vapory amethyst

Of marshes and swamps and dismal fens,
Scooping the dew that lay in the flowers,
Dipping the jewels out of the sea,
To sprinkle them over the land in showers.

We knew it would rain, for the poplars showed
The white of their leaves, the amber grain
Shrank in the wind —. and the lightning now
Is tangled in tremulous skeins of rain.

Conversation. — Have you ever seen "the sun drawing water," as children sometimes call it? Tell how the sun and sky looked at such a time. What lines in the poem seem to describe this appearance? Are there really any slender ropes and golden buckets dipping up the water? . To what fact does this word picture refer? How are clouds formed?

What is the color of amethyst? What does the word stand for here?

What five sources of the vapor that formed the clouds are mentioned in the second stanza?

How many signs of the coming rain are mentioned in the poem? Name them. What is the meaning of the word tremulous? What is the usual meaning of skein? What does the word mean here?

Commit the poem to memory.

*     *     *     *     *
PROSE AND POETRY

In the first lesson  we had a simple explanation of how rain is produced. It contains a series of plain statements about the evaporation of water, the formation of clouds, and the cause of rain. Each sentence states a fact. It is evident that the person who wrote the explanation was not trying to write something beautiful but rather to make the explanation plain, simple, and easily understood.

The poem in the last lesson shows you another view of the same subject. It gives you the poet's view. It shows how a plain, common occurrence like a thunderstorm calls up in the poet's imagination a series of beautiful pictures.

Be sure you see the word pictures — the sun letting down the golden buckets and scooping up the dew and the jewels (drops) of water, the poplars showing the white of their leaves, the grain bending before the wind, and finally the lightning mingled with the pouring, whirling rain.

Which is more beautiful, the plain scientific explanation or the pictures formed by the poet's imagination? Why do you think so?
NOTE: This next poem would be a good one to use for copy work or dictation:
THE CLOUD
 
As you read these verses, try to think of the cloud as a person who is talking to you and telling you what she does:
 

I bring fresh showers for the thirsting flowers
From the seas and the streams;
I bear light shade for the leaves when laid
In their noonday dreams.
From my wings are shaken the dews that waken
The sweet buds every one,
When rocked to rest on their mother's breast.
As she dances about the sun.
I wield the flail of the lashing bail,
And whiten the green plains under;
And then again I dissolve it in rain,
And laugh as I pass in thunder.

Shelley.

What is meant by "thirsting flowers "? Where do the showers come from? What is meant by "noonday dreams"? When the sun is very hot and the ground very dry, do the leaves droop as if asleep? Does a cloud have wings? In what respect is a cloud like a bird? When does the dew fall? What is thought of as the mother of buds and flowers? What is a flail? Why is hail spoken of as a flail? Why is hail called "lashing "? How does it feel to have snow driven into your face by a strong wind?

Go over the lines again. Name all the things which the cloud does. Memorize the lines.

Conversation. — Is there near your home a lake or a pond; a creek, a brook, or a river? If so, tell: —

1. Which form named above have you in mind? What is its proper name? How did it get this name?

2. Where is the water? How do you get to it? What are its surroundings?'

3. How does the water look? What use is made of it?

4. Why do people visit it in summer? in winter?

Written Exercise.

Write one or more paragraphs describing a body of water.

THE WATER DROPS' JOURNEY.
 
Some little drops of water,
Whose home was in a sea,
To go upon a journey
Once happened to agree.
A cloud they had for carriage;
They drove a playful breeze;
And over town and country
They rode along at ease.
But oh! there were so many.
At last the carriage broke,
And to the ground came tumbling
These frightened little folk.
And through the moss and grasses
They were compelled to roam,
Until a brooklet found them
And carried them all home.

THE RAINDROPS' JOURNEY.

Resting in a dark cloud were many little raindrops. They had a quiet life, but they were quite content to stay there in the great sky, rocking In the cloud-cradle, and dreaming of the time when East Wind would call them out on a journey to the brown earth. Mother Cloud had told them what that journey would be, so, as they waited, they sang merrily:

East wind will call;
Down we will fall,
Pattering over the green fields below
Gay little showers,
Bathing the flowers,
Washing the grasses and helping them grow.

At last, one afternoon a push from East Wind sent the cloud scurrying across the sky.

"Whew-ew-ew!" he called loudly, "are you ready to come with me, little raindrops?"
"Yes, yes!" they cried, tumbling out as quickly as possible:

Here we come merrily,
Down we come cheerily,
Gay little raindrops are we!
Wee silvery brother,
We'll help one another,
Together the great world we'll see.

Quickly they fell, soaking into the dry earth that the flower roots might drink the sweet, cool water, and on and on, until they swelled a tiny spring that bubbled out of the stones and moss.

"Come, journey with us," they cried to the spring, and ran on with merry song.

By and by they came to a little stream.

"Dear little brother," It said, "one little stream can't do much alone. Let's join hands and run together."

The two little streams hurried on, meeting others, and saying to all alike:

"We can have so much more fun together than by ourselves. Come, play with us." And now the streams formed a brook where flowers were refreshed and the meadow land made fertile by its cool waters.

Presently it found another brook, and cried, "One little brook can't do much all alone. We can do twice as much if we work together."

Now it became a large brook. Mother Sheep and her little lambs could drink from it, while, as it ran past the farm-house, the children could have fine fun sailing their boats on its merry current.

Other brooks joined it, and now it had come so far, and so rapidly, that it stopped to rest in a quiet pond, then more quietly went on its way.

At last it came to a great river.

"Do you need my waters?" It asked, and the river answered: "I could not live if the brooks and streams did not join me. Come help me, and we can do much good together."

Then the cattle were refreshed by the river water, mill-wheels were turned, hundreds of fish found a home, and men, women and children used and rejoiced in it. Boats went up and down, and where the river was broadest, great ships sailed on its calm surface. "How glorious to help so much," murmured the river.

At last the ocean was reached, and into its mighty arms the river hurried.

"Is this the end?" wondered the little water-drops. "Will we always be a part of the great ocean?"

The sun shone down warmer and warmer. It whispered, "Dear little raindrops, would you like to go on another journey, giving rest and refreshment wherever you go?"

Then, softly, they were drawn up in a fine mist by the sun's bright rays, until the merry little raindrops rested once more in their cloud-cradle, waiting for East Wind to bid them go forth on another joyful mission.

Scholastic has a SUPER little cartoon video showing and explaining the water cycle! Be sure to check it out.
Image from Science With Me - great website.

Here are a couple of "Water Cycle" songs to sing - makes remembering those big words much easier:


This first song is sung to the tune of She'll Be Coming Around the Mountain:

Water travels in a cycle, yes it does
(use pointer finger to make a big circle)

Water travels in a cycle, yes it does
(repeat finger circle)

It goes up as evaporation
(moves hands up to the sky

Forms clouds as condensation
(make a cloud overhead with arms)

Then comes down as precipitation, yes it does!
(sprinkle with fingers while bringing arms down in front of you)


 *     *     *

NOTE: Piano solo sound clip of My Darlin' Clementine can be found at Songs for Teaching, for those of you not fam
iliar with the song. For She'll be Comin' Around the Mountain, click the little red music symbol next to "piano solo" HERE.


Water Cycle
(Tune: “My Darlin’ Clementine”)
 

Evaporation,  
(Push palms up toward the ceiling.)

    Condensation,        
(Bring palms together over your head.)


     Precipitation all around,         
(Wiggle fingers as you bring your palms down.)

                      Accumulation,                         
(Sweep arms together as if gathering up something.)


      Evaporation,           
(Push palms up toward the ceiling.)

           The water cycle goes round and round.            
(Arms out by sides and make circles.)


        Evaporation, evaporation, water goes up in the air,            
(Palms up.)

     Gets together and condenses and rain clouds do appear.         
(Palms together over head.)


    Then it rains, that’s precipitation, water falls to the ground.        
 (Wiggle fingers down.)

     It accumulates in puddles and splashes all around.            
(Sweep arms together.)


The water cycle starts all over when it evaporates again.
It condenses in the clouds, then precipitation will begin.

Evaporation, condensation, precipitation all around,
Accumulation, evaporation, the water cycle goes round and round.

Keeping a Weather Record

The little voyagers continue to use the worksheets in the Living Life Intentionally Weather Packet. Rosetta has become quite proficient at reading the thermometer.


As you can see here, she is recording the temperature twice a day.


She and Saralina are also graphing the weather conditions. 
(Sorry, this one is a little blurry.)


This graph is for the types of clouds they see in the sky.


This fun worksheet is used to illustrate the child's favorite type of weather, then write a sentence about it.

NOTE: I can see a few words in Rosetta's sentence that will be added to her weekly spelling practice!

I created a basic "weather words" printing practice worksheet for Saralina, using the ESL Writing Wizard.  These words can also be added to her "weekly sight words," and used for a weather-themed spelling list.

Rosetta's "weather words" printing practice worksheet includes a few difficult words:  Fahrenheit and temperature

Ideally, students learn and practice reading the temperature on a real thermometer. But for assessment and permanent proof of mastery, you might consider making these handy worksheets to keep in a student's portfolio or weather notebook:



These worksheets were created using the custom temperature worksheet tool on the SoftSchool website. The nice thing about using this FREE tool, is having he ability to choose the temperatures. For Saralina's (kindergarten) worksheet, I chose basic, round temperatures like 40 and 60 degrees F.

Rosetta, being in 2nd grade can do more difficult ones like 62 and 84.
Not only can you choose temperatures to show on the thermometers, you can also choose (fill it in) ones that just show the temperature!


Looking for a fun File Folder Game? FileFolderFun has one for 2nd grade called Whether or Not!  For preschool, they have HOT or COLD, which could also be used for kindergarten.
