Hike at Sunol Regional Wilderness

Last weekend our pick for the Sunday hike was Sunol regional wilderness near Fremont. As it was father's day my kids and I decided to give dad a good workout!

One of the staff members at the visitor's center helped us pick a trail along the Little Yosemite area which is a easy hike for a 4 year old and is a mix of open and shaded areas. The trail offers panoramic scenery of the green and brown mountains.

The Little Yosemite area is along the Alameda creek and as you walk on the trail you can hear the bubbling and flowing water, it is very soothing. I guess it is called so because there are few low water falls and flowing water stream and a lot of greenary around. We happened to spot a banana slug near the water. There were fish fry and tadpoles in the water.

We spotted butterflies : California Buckeye and the Variable Checkerspot.



The place seems to be very popular as we saw a good amount of crowd there. One thing that put my kids off and they decided that the park was not good was because some of the owners had left their dogs without leash.

Lifecycle of a silkworm

The best way to learn science is to get close to nature and observe the surroundings. Nature has immense number of secrets and wonders which can intrigue kids as well as adults. Metamorphosis is one such amazing natural phenomenon.

This spring my preschooler's teacher got some hatched silkworms from the RAFT organization so she could have her students observe their lifecycle. She initially put them them in a shoe box
(as they were tiny) with plenty of mulberry leaves. The mulberry leaves is their preferred food, however they can also eat spinach or lettuce leaves. These worms were tiny light green and rusty.

The pictures below are of the silkworm, two weeks after they were brought:



However due to their enormous appetite they kept feeding on the mulberry leaves and grew. She moved them to a big plastic container with lid. All of them grew at different rates, however not a single worm crawled out of the shoe box or the plastic container!



As the silkworms grew the teacher started keeping rolls made out of thick paper sheet in the plastic container. 4 - 5 weeks after they were brought to school the first one crawled in to the roll and started making a coccoon. It made the coccoon within a day!


In the following 1-2 weeks most of the silkworms had gone in to their coccoons. Some of the coccoons were yellow. It is normal since those were wild silkworms and can have their coccoons in non-white color. As people prefer white color (as it could be dyed in to any color) they started breeding silkworms that would give only white silk.


For commercial use the coccoons are put in to boiling water and treated while the moth is still inside the coccoon. The enzymes secreted by the moths to break the coccoon damages the silk and hence they are not given any chance to come out.
After about 4-5 weeks of being in the coccoon, the silkworm moths finally came out. At this stage they do not need any food, nor do they fly. They go through the reproductory phase, lay eggs and die. These eggs can be stored in the refrigerator and used in the next spring to hatch more silkworms.



The silk from the cocoons is very strong and is stretched in to a hankerchief after treating the coccoons. It is then spun in to thread.



The entire lifecycle of the silkworm
(egg -> catterpillar -> coccoon -> moth) spanned over 2.5 months and almost everyday me and my kids watched it with great excitement.

Wild Zone

After a very busy work schedule for last 2 weeks, I wanted to keep this weekend activity very light. So we went for the Wild Zones program. This program is free and focuses on "unstructured play in nature". All that the kids have to do is use their imagination and build!

Since this was our first visit, we were not very prepared for it. Just carried the basic necessities of a hot day... water,caps and sunscreens. When we reached this place first thing we saw was mucky water and kids standing in it and playing with the mud. The first thought that crossed my mind was... I am in the wrong place! I was very sure my kids won't even go near it, leave alone getting in to it. We watched the other kids play, and then slowly my kids went for the spade and shovel to dig in the mud. Good start, I thought.

After their heart was contented, we decided to build house with sticks. We tried our hands at building a teepee! Not bad for beginners! We decorated our house with some flowers and took some pictures.

We had a funfilled 1.5 hrs and the kids decided that next time they would come prepared to play in the mucky water too!

Another afternoon at Ardenwood Historic farm

Our last visit (it happened to be our first visit too!) to Ardenwood Historic farm had filled my kids with a love for this place. The simple layout of the farm, the animals and the activities all contributed to it. When I gave my kids few options for places to visit over the weekend, they unanimously voted for Ardewood farm.

So here we were back at the farm and this time th kids enjoyed :

Bountiful bubbles: On a hot and breezy day it is fun to blow big bubbles with unusual bubble wands. These were made with 2 sticks on each side and a flat rope loop. There were simple metal wands for younger kids.

Vanilla Icecream: If you were born in olden days you would have to make your own icecream before eating it! The kids made vanilla icecream with an icecream maker from olden times, the cranking one. After mixing the ingredients in a vertical container, ice and salt(to lower the freezing point of the ice and make it more cold) were added around the container and kids had to turn the crank, so the mixture inside gets equally exposed to the lower temperature outside.

The kids then got to eat their icecream!

Old fashioned games: Kids were provided with things that they needed to play the old fashioned games such as walking on the stilts, potato sack race, balancing potato on spoon. They had fun trying out all of them.

This time we saw few more farm animals turkey, chicken and pheasant
