Special Moments in Time

Time is such a difficult concept for children and even some adults.  I often take photos when the children are busy playing – snapshots of special moments. Often the camera doesn’t fully capture what I saw but the photo can still serve as reminder of that brief moment in time.  These are some recent photos of moments that I found interesting.

These are the props the children have set up as part of their ‘Santa’ game.  The little tree they built from Bunny Blocks and the snack they have put out for Santa.  These preschoolers initiate this dramatic play activity many times every week – not because it is Christmas time but rather because it is something they enjoy doing together – cementing their friendships.  They take turns being ‘Santa’.  The ‘children’ pretend to sleep in makeshift beds in the corner of the room while ‘Santa’ gathers their favorite toys from around the room to give each child as gifts.  They demonstrate such wonderful understanding of what their friends like and the importance of giving to others.  Christmas was months ago but time is irrelevant.

The children also enjoy purposely slipping on ice patches on the backyard deck and walkway. I keep breaking up the icy areas or covering them with sand – not because I don’t want the children to have fun but because I don’t like falling.  The activity was not a problem but there was a better place and time for it – I took them for a walk so they could slide here;

February was officially ‘I love to read month’ and I didn’t plan any special activities.  With this little group reading is always a special activity especially when you’re with your friends.

Another special time is the end of the day when there are only one or two children left – they wait for the ‘magic’.  When the conditions are right at the end of a sunny day if you’re lucky enough to be the last to go home you may be here when this happens.

For a very brief moment in time the sun will make the music area sparkle.

Sadly, now that the time has changed we probably won’t see this again for a while but some day in the future the magic will return.  It will just take time.

Sensory Play

Sometimes I can be a hoarder – buying and hiding supplies for ‘later’.  It could be that I think it may be a fun activity but not interesting for the group currently in care.  It may be that the time or space is not yet appropriate and the activity will be offered when the conditions are right. Yes, admittedly there have been times I’ve forgotten about some supplies and then re-discovered them while looking for something else.

Last summer I set aside supplies for two sensory play activities that I wanted to do in the winter.  Usually I like to do messy play activities outside so summer would be best but for these activities I thought a ‘cleaner’, indoor environment would be better.  Besides sometimes in the winter we can’t be outside as much as we’d like to and we need something different to do when we are cooped up inside.

So, earlier this month when it was bitterly cold outside, we tried a new play dough recipe.  Yes, we’ve made and played with play dough many, many times but this recipe claimed to make ‘stretchy’ play dough.  It used one part hair conditioner and two parts corn flour.  I let the children each mix their own batch.

18-01-sensory01

There was a lot of trial and error – too wet, add more flour – too dry, add more conditioner.  Maybe it was the quality of the dollar store conditioner but the mixture never did become stretchy however the ‘coconut’ scent was a pleasant break from winter.  Later the children added the paint colour of their choice and when done we bagged each one separately so we could play with them again on other days too.  Not exactly the result I envisioned but still enjoyable.

The second activity I offered was water beads. I’ll admit that when I first got them I doubted that teeny tiny bag of wee little dry beads would be enough for all the children and thought maybe I should have ordered two bags.  I put the package in my desk drawer to save for a week when it was really cold outside.

Last week I filled two bins with nice warm water and added some dry water beads – at first they were barely noticeable in all that water so I also added some pipettes and other water toys too.  The children enjoyed the water play and eventually the beads soaked up enough water that we could see them better but they were still almost impossible to pick up.

18-01-sensory02.jpg

Later that afternoon we checked and they had soaked up all the water – this was really exciting!  This is what HALF a teeny, tiny bag of water beads looks like when they are all wet;

18-01-sensory03

I love the way the water beads feel – they may be one of my favourite sensory bin items 🙂 and the children really like them too.  I don’t even mind when the occasional one bounces out of the bin – even when I accidentally step on one it doesn’t break. Picking up strays is a whole additional activity.

The instructions say the beads are reusable so we experimented by putting a few in a smaller container and letting them dry out.  It took just two days for them to dehydrate back to their original size.  If I had taken a ‘before’ picture you would see that when wet these beads had filled the whole bottom of this container – magic

I’m certain this is an activity we will enjoy many more times to come.  In fact, I’m wondering if we might even try putting some in a container on the light panel…

From Beginning to End

The project began last fall when we saved some of the seeds from the pie pumpkin that came in our Wild Earth Farms CSA bin.  I think it is important to not only know where your food comes from but also where your seeds come from.  Most of the plants we grow in our garden start as seeds we collect from plants we have grown or food we have eaten.

In the early spring we started some of our seeds indoors – the seedlings really liked the box window location.  The preschool table is located in front of this window so the children got to see the progress of seedlings every day.

16-11-be00

Once it got warm enough outside we moved all the seedling to our outdoor gardening space.  The various squash plants got planted a block away in my daughter’s back yard – she doesn’t use her outdoor space and we don’t have enough room for those sprawling plants.

Throughout the summer we often stopped by her yard when we were out for a walk.  We are supposed to do some weeding and yard work when we go but mostly all the plants are ‘wild’ and just grow however and wherever they want.  Between the squash plants and the weeds there are so many prickly things but the children are still excited to explore every time we visit.

By the end of September her yard looked more like a jungle than a garden.  The children enjoyed searching for things to harvest.

16-11-be01

We found quite a few on this trip over – had trouble carrying them all back.  All the drivers were smiling as they watched our little parade cross the street.

16-11-be02

When we got back we examined the various produce and discussed what we would do with them.

16-11-be03

The flowers were added to our spaghetti at lunch that day.  The zucchini was used in a stir fry the following week.The rest were displayed as decorations until the end of October when all the pumpkins had turned orange.  Then we cut open the pumpkins and scooped out the innards.

16-11-be04

Then I roasted the pumpkin halves to prepare them for the next phase.

16-11-be05

The following day the children took turns mashing the cooked pumpkin.

16-11-be06

We added the other ingredients – everyone got to smell and even taste some of them before we mixed them in.

16-11-be07

Almost done;

16-11-be08

We poured them in to pie shells and baked them in the oven. Afternoon snack on Friday – perfect end to a busy week;

16-11-be09

There were comments like “This is better than birthday cake”.  Some of the children recognized the taste or smell of the various spices – savoring every bit to pick out the individual flavours.

A year long project from beginning to end – but, its not really the end, is it;

Stick Insect(icide)

We have had stick insects as ‘pets’ for the past six years.  When we got our first one the children were all so excited and there was a long process to pick a name for her.  It didn’t take long for us to discover that stick insects are so prolific that naming them all is impossible.

I think having stick insects is a wonderful science activity.  As with any activity some of the children are very interested – watching the insects for long periods of time, eagerly anticipating the hatching and molting stages and more.  Other children have little interest and rarely even notice their existence in our room.

16-10-insects01

The ‘baby’ stage is my personal favourite.  They are cute when they first hatch although they can occasionally escape when they are that small;

16-10-insects02

I only keep a few of the eggs that are laid and even then when they hatch it sometimes seems like we may have too many.  Sadly (luckily?) only a small percentage of the babies make it to adulthood and lay eggs for our next generation of insects.

Sometimes the little ones are hard to find when they camouflage on the sticks or on the lettuce leaf;

16-10-insects03

As they continue to grow they are easier to see but they also make more mess;

16-10-insects04

On a few occasions we have run into a problem when we have a particularly large number of insects at various stages.  The adults make the cage very dirty but the numerous hatch-lings make it difficult to properly clean and keep everyone contained.  If it is winter I will take the container outside briefly to clean it – cold insects are slow insects.

Last month we were at the overcrowded, filthy cage level but it wasn’t yet cold enough outside to slow them down.  Then something unexpected happened.  I ran out of romaine lettuce and there was NONE in the fresh produce section of the store where I was shopping.  Instead of making a special trip to another store just for insect food I decided to buy a package of romaine hearts.

Back at home I tossed two leafs into the cage for the insects.  The next day ALL of them were dead.  A hundred + infant to adult stick insects were strewn across the bottom of the cage.  I assume insecticide caused the mass extinction and I know I won’t be buying packaged romaine hearts for any reason anymore.

For the first time in six years we have no stick insects.  I managed to save a few dozen eggs when I cleaned the cage but only time will tell if the insecticide affected them too 😦

Mud and More

June 29th is International Mud Day – something we celebrate every year.  This year the school-age children were thrilled that there was no school so they were able to join in the day’s activities.  I had the water table set up full of dirt – it was up to the children to add the water and make the mud;

16-6-mud01

I also put out another bin with plain water for hand washing but some of the children enjoyed making repeated trips from mud to hand washing and back so really there were TWO mud bins.  I cleaned the hand washing bin and added fresh water several times but it always looked like this;

16-6-mud02

Because of this;

16-6-mud03.JPG

We were outside all morning and the children took breaks from mud play to build bridges;

16-6-mud04

play tag, and capture things like this;

16-6-mud05.JPG

There was a five minute downpour which was very exciting after I reassured the children that we would NOT have to go back inside.  We do often play in the rain but because we didn’t have raincoats and boots some of the children were concerned that we were not properly dressed for the weather.  However, it was Mud Day and everyone had clean clothes waiting inside so  all that rain was just a bonus 🙂 It created some muddy puddles and the tarp became a slip and slide;

16-6-mud06

and the mud table got soupier;

16-6-mud07

Then, one of the children notice that the first tomato has begun to grow.  Three of the children decided to ‘watch’ it for nearly 20 minutes ‘waiting for it to turn red’.

16-6-mud08

I think maybe it will be ready when they return in two weeks – after my vacation.  I wonder if they will remember to check, or will they be too interested in exploring all the other new things – my ‘vacation to-do list’ is two pages long.  I love vacation time but the return of the children is so exciting too!

Bees and More

We have many insects in our yard.  Our garden has several plants chosen specifically because they attract insects.  The bees love the giant hyssop and we love watching the bees;

PB00

This butterfly was outside the yard when the children first saw it.  They called it repeatedly and finally it obliged and flew into our garden so we could see it better.

PB02

Earlier this spring we had a nest of baby spiders by the bench;

PB01

Those baby spiders entertained us for several days before they left to find homes elsewhere.  The children were very protective of the baby spiders and ensured no one sat on the bench and damaged the web.

Some of the children are afraid of bugs – especially spiders and wasps.  I believe that learning about the insects we encounter will help the children overcome any fear of them. When we know what these insect do we begin to understand how they can benefit us.

Even wasps are welcome to visit our yard – they have a job to do in the garden too.  We don’t let them build their nests where we play though.  When they are near we give them the respect they deserve.

Daily I am summoned to various parts of the yard by a child asking “What kind of bug is this?” That question is followed by many more.  I don’t always have the answers but we do research to find out more.

I always try to remain calm even when we discover insects that I don’t like – such as these aphids we just found on the oats in our garden;

PB04

Where are the lady bugs – we need them now!  A strong negative reaction may instil unnecessary fear.  I’ll explain why I dislike certain insects and what we can do to avoid contact with those that we don’t like.

Earlier this week two of the girls were sitting in the garden smelling the herbs and flowers.  They were conversing quietly and I overheard one say “Ok, it’s your turn to pet him now – he’s really soft.”

I moved closer to see what they had found.  It was a bee – possibly the biggest, fattest, fluffiest bumble bee I have ever seen.  It was busy moving from one flower to the next and every time it landed the girls would PET IT!?!?

I tried to remain calm as I said “Please don’t pet the bumble bee.” but I’m sure my voice was a much higher pitch than normal.

“But we love him” the girls replied.

“Yes, I know, but he’s busy working and we don’t want to make him angry.  Watch him but don’t interrupt what he is doing.”

Love my job 🙂

Outdoor Adventures

We’ve been spending a large portion of our days outdoors.  We still come in for meals and naps but go outside for the majority of our play time.

I’ve put up the sunshade and on a few occasions I’ve opened the umbrellas too to provide shelter from the sun’s rays.  There is also a new cover for the tipi:

NA00

We added some peat moss to our planters and planted some carrot seeds:

NA01

The baby prefers a more hands on approach to gardening:

NA02

‘Ben’ and ‘Jen’ – the two worm-like critters  we found in the garden last week – still have a ‘home’ even though they show no signs of life:

NA03

Full water barrels and warm weather have allowed the opportunity for some water play too.  This is something new for the babies.  They were hesitant at first but soon realized that they were welcome to join in so they did:

NA04

The older children made soup – of course.  This time they added a new ingredient that they called ‘vitamin R’ (rocks):

NA05

They also cleaned the yard with ‘cloths’ and a ‘sponge’:

NA06

That piece of bark ‘sponge’ did a suprisingly good job:

NA07

I’ve got many more pictures of our recent outdoor adventures but I’m running low on time so I’ll save them for the next post.  Make sure you head outdoors for some vitamin N too!
