What happens when elephants are used in 8th grade science.

Today we had a winner for the show what you know writing exercise.  I asked the eight graders to show their understanding of using the formula for force. Force = mass x acceleration.

For the following known facts students were asked to write a short paragraph that included quantitative and qualitative statements and found the acceleration of one object.

Force = 150N
Mass = 1000 kg
Items that exert or receive force = an elephant and a truck.

The winning write up was this;

One day, an elephant walked upon a smelly Honda Pilot. Dark grey elephants are common in Dunbarton.  The elephant which had a mass of 1000 kg made a loud honking noise and stepped onto the truck. The 150N force of the elephant made the roof of the truck accelerate down at 0.15 m/s/s.  Unfortunately, the insurance company wouldn't pay for the truck because they didn't believe an elephant stepped on it.

A bear and his seeds

Boris the bear entered his greenhouse on a very snowy early spring morning.  Today would not be a good day for gathering sap in his maple groves, it was far too cold outside for the sap to be flowing like it had earlier this week. Temperatures in the temperate forest this time of year were unpredictable, as unpredictable as the snow this morning.  The only thing that Boris knew for sure was that winter had always been followed by spring, with summer close behind.

Summer was why Boris was in his greenhouse today, he needed to start some of the plants that he would be growing in his gardens this summer.  He had customers who depended on his crops of vegetables as well as the honey that the local bees made for him.  Today he was starting some zinnias for the bees and some long growing tomatoes and peppers for the community.  ThirdLittlePig over in Point-du-Farme, had requested several varieties of peppers and a large variety of herbs for his new diner, that he opened last fall and Boris decided to start the herb seeds today as well.

A few hours later with the scent of fresh soil in the air, and new pots of labeled seeds on the greenhouse benches, Boris smiled to himself and thought; here was a time of year when many a bear would turn over in his den to sleep out a few more weeks of hibernation, but instead he was happily busy planning and planting with summer gardening on his mind.

My very educated mother just made us nice ... ???

A short story based on a sixth grader's question in class this week.

Finishing up his science work for the day, Collin was thinking about what the teacher said about Pluto, that it probably didn't mind that it was now a dwarf planet and not one of the main nine planets of our Solar System.  Then it hit him, from out of nowhere, he had the thought; "What if Pluto does CARE?"

Suddenly he realized that he was actually thinking out loud.

"What are you talking about?" Alex said, as he continued packing up his backpack at the end of class, "Pluto is just a bunch of frozen ice and rock, it doesn't have feelings"

"How do you know? Maybe does and we just don't know it,"  Collin continued, "it could be true, you know!"

The rest of his classmates just rolled their eyes in disbelief, "Seriously? said Samantha, with an air of sophistication, "Pluto is an inanimate object, it is just rocks and ice like Alex said, it can't have feelings, have you been paying attention at all in class, sheesh."

Collin wasn't about to give up so easily and shouted, "YOU DON'T KNOW ANYTHING!" as the rest of his class left for lunch.  "I'll show them, I'll show everybody" he said to himself taking a detour towards the computer lab instead of the lunch room.

Some older kids were already in the computer lab as Collin signed in for the lunch period then headed to the back of the lab for his favorite computer.  He worked through the whole lunch period, missing his recess.

Several days, and missed recesses later, Collin ran into his science class super excited and shouted "I FOUND IT!" then more quietly, "You all have to come and see this."

"Shhhhhh," said the teacher, "Not so loud, but what is it that you want us to see that seems more important than learning science?"

"It is science." Collin replied, "But you have to come to the computer lab to see it."

Curious now, the teacher said, "All right, if only to settle everyone down and get back to work before the period ends, lets take a quick look at your computer."

The class lined up and headed for the computer lab, Collin led the way.   Once all had gathered around the computer screen, Collin hit a button that turned the screen on.

There were gasps, giggles, and screams, along with the teacher picking up the phone and asking for direct contact with NASA.

"See, I was right," said Collin proudly, "Pluto does care, that photo says it all."

What was on the screen?  Do you know?  Once he gets the copy of the photo back from the International Astronomical Association, who are double checking his findings, Collin will post it here.

Stanley Boris Bear

Stanley Boris Bear, who was named after his granddad, went by the name Boris to avoid confusion while his granddad was alive, and had taken over the family farm after his granddad passed away. By improving the farm here and there, today he owned a large business that centered around crops that produced sweet fruit, honey and maple syrup.
This morning Boris walked up to the top of his maple grove, to a ledge that had a grand view of his farm. From here he surveyed all that the new year had in store for him. The late winter was starting to turn into spring when the maple sugaring season would come to an end. Boris observed healthy trees in his maple grove, about half were currently in their peak production years for creating good sap for syrup. The other maples were a mix of young saplings and very old trees that had lived long enough to be left alone during sugaring season. Several dead maple trees stood in this grove, Boris chose to leave them standing as homes for birds and small animals. Eventually these trees would fall, sometimes the whole tree at once, but most often piece by piece, or limb by limb, adding to the humus layer of decaying materials that provided nutrients to the living forest.

Sap House at Work - B. Bear

As he took a break from his work in the sugar house, B. Bear spotted several pair of cardinal in the pine trees nearby.  Out among the trees and shrubs, next to the sugar house ,were a large number of chickadees, house finch, junco and other birds that either did not migrate for the winter to the south or had migrated to this area from farther north.
A coopers hawk had been sitting on a high branch of one of the maple trees causing the bird activity to cease for a short time.  Once the hawk flew off in search of an easier meal, the small song birds began grousing for food in the tree branches and on the ground around the area.
Soon a family of squirrels walked up to the sugar house, knocked on the door to announce their arrival.  B. Bear welcomed them all in and showed them the evaporator and how it worked to boil down the sap into sweet sticky syrup.
   "Who wants to try a taste?" offered B. Bear.
   "I do, I do, I do", came the quick reply of several young squirrels with great enthusiasm.
   "You will all get a turn," added a more mature voice, "let the youngest go first, this is their first taste of the sweetness of spring, remember how it was for you last year."
   With a murmur of agreement, several young squirrels stepped aside and a tiny yearling reached up her paw to take the small acorn cap full of syrup from the large, though quite nimble, hand of B. Bear.
  "MMMMM!!" the tiny squirrel exclaimed, "this is the best thing that I have ever tasted!"
   With that, her siblings lined up for their turns and also gave their approval of B. Bear's syrup, and generosity.
    Taking their leave a short time later, the squirrel family thanked B. Bear for his time and went on their way.  B. Bear returned to his work bottling his syrup into fine glass containers and jugs that bore his trademark paw print with his initials inside.

B. Bear - working on ideas for the maple sugaring theme

B. Bear overslept this morning, he was surprised to have his sugar house buried in over two feet of new snow from the storm overnight. After spending an hour digging out the door, B. Bear stepped inside, lit the fire in the arch and got to work thawing out the sap in the collection tanks. He knew it would be a while before the frozen sap thawed and the sugar house warmed up, so he kept himself active by bringing in wood from under the covering outside and splitting it into smaller pieces to fit better in the arch.

Space Junk Collector - a student question story

One of the kids asked yesterday, "wouldn't it be cool to be a space junk collector, like have your own space ship and gather space junk?"

Gabe turned his ship around and headed back toward the inner Solar System.  He had finished his rounds near the gas giants his debris hold was full.  One of only a few adventurous ship captains who took the extra risk of gathering space junk while transporting humans and cargo to their destinations either moon, asteroid or planetary, Gabe did his job well and had a fine reputation as any in the space industry.

In the early days of space exploration, space junk was allowed to burn up in the atmosphere of the planet that it was orbiting.  That was until resources became scarce on several planets that had big manufacturing facilities and the call went out for volunteers to gather up the bits and pieces of old satellites, abandoned space homes and even tiny nuts and bolts that fell off of or were dropped by construction crews as they built or repaired space homes and stations.

Though he did not volunteer, Gabe knew a profitable idea when he saw one and quickly chose to clean out a section of the cargo hold in his ship to store space junk picked up in his travels and sell to the highest bidder.  Other space ship captains had done this as well and the extra income had helped all of them plan for their eventual retirements on one of the more hospitable planets in the Solar System.

With his extra money, Gabe had upgraded the gravity controls of his ship.  This allowed for him to adjust the gravity onboard for his passengers as they travel from one planet to another.  He would set the gravity for the planet that they were leaving and gradually throughout the trip adjust the gravity to that of the planet that they were headed for.  By the time that they reached their destination passengers had physically adjusted to the new gravity and needed far less time acclimating upon arrival.  Word had gotten out that Gabe's ship had this feature and the number of passengers on each flight had increased quite a bit recently, which was good for his retirement fund.

On this run, out near the gas giants, Gabe had picked up an old Earth space probe that had stopped functioning over 400 years ago.  It had been launched on August 5, 2011 and began orbiting Jupiter on July 4, 2016.  After its mission to orbit and gather data was completed, the space probe was to be crashed into the Jovian atmosphere to gather data prior to its destruction to learn as much as possible about the atmosphere of the planet.  Unfortunately, the space probe stopped transmitting information back to Earth just prior to receiving the program to end is mission and had not been heard from again.  A recent sweep of the moons of Jupiter by a telescope orbiting Mars had spotted the defunct space probe near the moon Ganymede.  The Inner Planetary Space Agency, the modern name for the founding organization NASA, had hired Gabe to retrieve the space probe and to bring it to Mars for analysis.

Curious about his cargo, but careful enough not to mess with the very old and delicate machine, Gabe had carefully stored the space probe in his debris cargo hold.  He set the gravity and atmosphere in the hold to match that outside in space to protect the fragile cargo from damage due to sudden pressure and gravity changes after having been orbiting in space for so long.  Earlier today as he sealed the hatch to the debris hold, Gabe thought he had heard a faint, but continuous. hum coming from the space probe that had been silent for so many years.  He thought to himself that he was imagining things, he had been in space long enough to know that the mind would play tricks on him at odd times, this seemed to be one of them.  He was happy that he would be heading home soon to a long awaited vacation on Mars with his growing family.

He was thinking about the space probe as he turned his space craft toward home, he wondered what would be learned from the long missing relic.  Little did he know, but indeed the space probe was humming in the debris hold, now that it had been in contact with a human it was beginning to wake up.  It had a message stored in its data banks, an important message that would change humanity forever.

Loupe Falls

Loupe Falls was a prosperous town with in the temperate forest biome, bordered on the east by mountains, through which a pass led to Point-du-Farme. To the north were rolling hills of drumlins and moraines left behind by the last glacial age thousands of years ago. South and west of the town a large expanse of deciduous forest stretched for as far as a wolf could walk at a leisurely pace in five days. Beyond that, the land began to rise again and with increasing altitude, the forest changed from deciduous to coniferous.
Near the north edge of town a river flowed following the path of least resistance as it meandered its way to the sea many days travel to the southeast. As the river approaches the town, it flowed over a high granite ledge in a spectacular and roaring waterfall. The waterfall was not only a place where animals from other areas of the biome came to visit in their travels, it was also the name sake of the town. The falls were named for a prominent resident of the area back in the days before Free Game Preserves were established, when each town was populated by one species and raids on other towns for food. This memorable wolf had gone to a neighboring town one spring morning in search of dinner, found the homes of three pigs, and in the course of the home invasions ended up with his tail being lit on fire by one smart pig who had plans for longevity.
According to the rest of the story, told to local children, this wolf came home quickly from his hunt and sat down in the river to cool his sore, tail. Unfortunately, the river current was running high at that time due to a higher than normal spring run off from the snow melt, and the wolf was quickly swept from shore. Witnesses said that the wolf scrambled wildly trying to get back to shore to no avail and eventually was seen going over the falls to his death.

In the blueberry patch... new ideas for another story...

.... and B. Bear arrived near the top of the mountain where there was a large patch of low bush blueberries. This was why he had climbed the mountain, his mouth watered as he approached the plants and began to eat. As he ate he also pruned out the old overgrown plants, letting in light to the younger shoots with anticipation for even more blueberries next summer.
Sitting back after eating his fill to admire the view from this height, B. Bear spotted several wolves on the other side of the blueberries sunning themselves on the warm rocks, that is all except one that had a curled tail. This wolf seemed to be in the blueberry patch grazing the berries, his lips were blue with juice and he apparently was enjoying this taste of summer.....

Wolf Anxiety

This is the first chapter to the book PigBadWolf


Point-du-Farme was a small town out far beyond the furthest edge of Calabaza Lake, the major city of the Temperate Forest Biome, actually a little further than that, on the northeast side of the biome’s mountain range, in a valley that was the center of a large watershed, fed by glacial rivers and streams.
The town was host to an array of plants, animals and assorted geological features.  Flying over town, a Falcon would see an expansive pine and evergreen forest to the north, out of which flowed a smallish, but not to small river bordering the town on the north and west sides. The river ran south into a mid-sized lake, and out again at the south-western tip, where a family of beaver maintained the old dam.  The lake was a natural lake, with an added dam to keep the water level constant and the lower end of the river navigable for commerce.
Near the dam end of the lake, on the west side of town, there were fields of grain; oat, wheat, rye, barley and sorghum.  Farther east Falcon would see a mixed forest of hardwoods, especially noteworthy would be the large grove of ironwood trees.  A verdant carpet of pasture lay in the northeast corner of the town just north of where the edge of the hardwood forest meets the pine forest.
The town itself was a mixture of homes built with a variety of natural products created by local home builders and furnished by local artisans.  As mentioned earlier, the town is a bit too far from anywhere, not to be sustainable in its own right with locally grown and produced products, including the majority of the food and resources needed for the survival of the local community.
Along with the old dam, the beaver family ran a ferry service which provided transport to town folk, carrying mail, produce, children heading to school and an occasional traveler from away, across the lake to the town.  The ferry stopped at points along the shore to pick up and drop off passengers and packages, the last stop being the edge of the rapids near Strawhouse Hill. 
On the top of Strawhouse Hill, was the house for which the hill, and the lane leading up to it, is named.  This was not your standard straw house made by just any builder, this was the house of the FirstLittlePig, who apprenticed in the fine art of straw weaving and straw home construction. The homes that he built are made of the finest straw-bales, not only aesthetically pleasing on the outside, but tastefully decorated on the inside with handmade straw mats, wall hangings and furniture.  FirstLittlePig hired only the best straw artisans to work with him and he maintained a fine, and respected reputation for the quality of his construction projects.
From inside the house on a spring day, you can hear the sound of the rapids as the water washes over the rocks and down to toward the lake.  Today was such a day. As FirstLittlePig sat at the breakfast table, scanning the newspaper spread out in front of him. The top of the front page read;
Wolves spotted setting up new home in the Pine Woods
The headline sent shivers up his spine, his old childhood anxieties began to stir.  MotherPig had told the boys stories about their ancestors back when he was a very impressionable child.  One such story was of a great-great-great-grand uncle who fared poorly in an encounter with a wolf who had a strong breath of wind.  FirstLittlePig had nightmares for months after and then several years of therapy to recover from this story, his fear of strange wolves remained on the surface even to this day, even with his success as a fine builder of straw houses that could hold up even in hurricane force winds.  New wolves in the area would not know how this town ran, they would not know that all animals lived as equals in Point-du-Farme, and that the only area for hunting was across the river in the Free Game Preserve.
The local wolf population were prominent members of the community, many were members of the protection squad, who kept the town safe from raids by the L.A.B. facility many miles to the south.  The Laboratory Animal Business was notorious for raiding the land south of the town, grabbing any animal it could find and conducting secret tests on the animals, holding them forever to see how the animal adapted to new surroundings or even worse selling them to other research facilities or gasp to food production.  The town had many community members who had escaped the L.A.B. facility or had family members who had been in captivity there.  The protection squad had been hard at work for numerous generations, and no town members had been lost in recent years.
So, FirstLittlePig knew the value of the town wolf population, but he feared any new wolves coming into the area, his phobia had been kept in check for so long, but this headline was putting him well over the edge.  Working to settle himself down, he continued to read the paper and there on the bottom of page five was an advertisement;
Wolves have you worried? 
Fear no more, our new and improved pill
 Wolf-Phobia-Be-Gone - will keep your fears at bay! 
Only $19.99 for a three-month supply, order yours today!

Most people would have skipped past this add, but FirstLittlePig felt that one could never be too sure, and the old phobia coming back now would surely hurt his straw home business.  He took out his cell phone, found the website and placed an order to be delivered overnight.
