"Spring - an experience in immortality"

Henry David Thoreau

As Thoreau suggested, Spring is about renewal of life and spirit.  In Gan Shalom this month, we are experiencing first hand new life all around us.  Our Director prepared the coop for the arrival of our new feathered residents.





 



Our white Silkie is a favorite with the children.

Our children can't wait to see our new friends.

We also have five chicks that are not ready to move into the coop.

We were looking for insect eggs and discovered these on the cardoon plant.  As the children looked more carefully,  they saw the larva and pupa of a lady bug.

The children documented the life cycle of a lady bug as witnessed in Gan Shalom.

Do you know what this caterpillar really is?  Our students will tell you that it is the larva of a Fritillary butterfly.  To celebrate Spring, we made tissue paper butterflies.



Lunch scraps, the FBI, and Humus

Spring is on the way and that means a long list of gardening chores.  Before the children prep the beds for planting, we need a good supply of humus.  Because each class has been contributing their snack and lunch waste since September, we have a ready supply at hand.  We just need to separate the finished humus from the material which is still decomposing.

Compost is simply organic material that has decomposed.  It is essential to organic gardening because it returns nutrients to soil.  Humus is the finished product used as a soil amendment. 

We use a system of screens made from nursery plant trays and trays from a worm bin.  The first screen set has large openings and the second screen set has smaller holes.

The children scoop material from the compost bin into the first screen set.  With a little shaking, the smaller pieces fall to the tray.  The larger pieces remaining on the screen get returned to the bin to continue decomposing.

The first tray is poured onto the second screen.  A little more shaking and the humus falls down through the small holes to the tray. 

The children felt the finished humus and compared it to the original compost material.  The humus was described as "small" and "crumbly". 

When they looked at the humus, they could not tell what it had been, but the compost material still showed pieces of banana and orange peels.  They are able to see that the unused food was not wasted, but is now providing nutrients to the garden.  This practice is one method of teaching the concept of bal tashchit.

Here's a little video of a member of the FBI; fungus, bacteria, and invertebrates.  They are the allstars of decomposition.

February Surprises

 This is what February in Dallas looks like.  At least for one week during 75 degree days.   The tulips were planted in December anticipating a beautiful show in April.  Alas, it is now March 18 and only stems remain.  They were beautiful while they bloomed, even if it wasn't on my schedule.  But, that is what gardening reminds us.  We are not in control.  G-d through nature continuously brings unplanned and unexpected surprises.

After the beautiful,  sunny days, came the rains.  And I had a few surprises for the students.  We donned rain ponchos, grabbed our hand lenses and went exploring.

Some of the leaves collected water drops.  This cabbage leaf looks like a swimming pool for a lady bug.

When the rain stopped, we found a big puddle in the parking lot.  I challenged the children to "think like a scientist" and make observations about the puddle.  Several children noticed that the surface of the water acted like a mirror.  They commented that they could see the trees and the building in the water.  One child noticed that the water was moving.  I asked her what was making the water move.  She watched for a moment and then answered, "the wind".

Finally, some noticed that leaves were floating on the surface.  I asked them if they could create an experiment using the puddle.  They gathered items found on the ground and conducted a sink and float experiment.  At one point a pansy was floating.  The wind caught it and moved it forward.  One child picked it up, then placed it back on the water.  But, it was turned upside down.  The children noticed that instead of floating, it partially sank.  After a period of discussion, they decided that it sank because it had water on top of the petals.  And water made it too heavy to float.

A Gourd By Any Other Name Part II

I believe we left the story just when the students discovered the gourds growing in the gan...

One of the plants had several overgrown cucumbers attached to the vine.  They had not been harvested in time to eat them, but I had intentionally left them growing for this lesson.  Once the fruit passes it's peak time for eating, it then focuses energy on seed production.  And the seeds are what we investigated next.

I asked the students what they would see if I cut the cucumber open.  " I think seeds are inside" was one answer.  One boy said " there is water and slime".  I then showed a slice of the cucumber so that they could confirm their guesses.

Next, pairs worked together to disect a slice. 

  The instruction was to separate the seeds.

I asked what the inside felt like.  Descriptions included "it's squishy", "slimy", and "gooey".

One boy said "it feels like rainwater".

Another exclaimed, "I feel like I'm dipping my hand in a cold puddle".

 These two boys worked very diligently on disecting the slice.  Most children simply dug out the center in order to separate the seeds.  But, this team actually quartered the slice and carefully removed the seeds. A mastery of fine motor skills was required to hold the cucumber in place, then move the knife in a slicing motion.

We placed several of the cucumber seeds on a tray and investigated them.  I asked for a description of the seeds.  I explained that we would create a list of characteristics that would describe what the seeds look like.

Most everyone began with describing the color as white.  When I asked what shape they were, the children said "oval".

I asked them to take a close look at the ends of the seeds.  Are they smooth and rounded, or are they pointy on the end?



After close observation, they determined that there was a pointy end.

 It was also agreed that the seeds were flat not "puffed up".  Next I placed a series of seeds on the tray next to the cucumber seeds.  The children used the list of characteristics to compare the new seeds with those that were disected.

Observations included "they are round and not oval", " they don't match", "the other seeds are puffed up and round".

One set of seeds matched all the characteristics except for the color.

The research showed that three out of four characteritics matched.








The students discovered that the seeds were from a different type of gourd plant.  They grew from a loofah gourd plant.

At the conclusion, the children understood that gourd seeds share similar characteristics, just like leaves from a gourd plant.

The Pre-K class concluded with a journaling activity.  They documented the gourd, the oval shaped seed, and the spikey stem and leaf.

A Gourd By Any Other Name...

I arranged an assortment of gourds on the ground.  I asked the children to describe what they saw.  One child said "some are pumpkins and gourds".


One girl noticed a pumpkin leaning to one side.  She said, "one of the pumpkins is not standing very well".



Other observations were "a pumpkin is a circle" and "it has a stem".

Next, I asked them to group the pumpkins together.  Some children put everything that was orange in one group.  Others combined the ones that had a visible stem. 

Some looked at the shape and grouped round ones together.











 After several attempts, they discovered that there were only three true pumpkins in the group.

Then they found out that pumpkins are part of a larger family of plants called gourds.

Next, I placed a variety of leaves on the ground.  Each child came to investigate the leaves.  They used their senses to gather information.  I asked them to describe the leaves.

Descriptions included "the stem is so spiky", "this one is soft, this one is scratchy", "this one feels bumpy", "this one is a pokey one".

One child observed, "these two leaves kind of feel the same because they're both bumpy on the stem".

They found out that leaves from a gourd plant have spikes on the stem and are scratchy  when you touch the leaf. 











Then we went on a discovery walk to locate the gourd plants that grow in our garden.  The children had to use their sense of sight and touch to locate the correct leaves.

They found the leaves near the front of the gan.  The two plants were growing cucumbers and cantaloupe melons.  The children learned that cucumbers and melons belong to the gourd family.

They knew this was true because of the characteristics of the leaves.
