Field Trip: Train Ride to Olvera Street

My girls and I love to "ride the rails"!  Today the destination was Union Station in LA and then a walk down Olvera Street.  With a 4 year old and a 6 year old in tow and teamed up with two other Moms with their little ones, we left Irvine headed for Union Station on the MetroLink.  Here are the highlights!

Train Ride to Union Station

The train is definitely a highlight of the trip.  We had maps of where we were going and coloring sheets to keep the kids busy on the train but they were more excited about riding on a train and looking out the window! 

Good to Know:

  • Free parking at Irvine Station is in the garage across the street.
  • Tickets can be purchased at the ticket machines.  Credit cards are accepted.  
  • Children under 6 ride for free.   
  • Tickets are checked on the train.  They were not checked this trip. 
  • This trip cost us adults $21 each (it would have cost us more in gas if we drove!) 
  • Navigating the station: figure out which track is headed north and that the train is going to the end of the line - Union Station.  Use the bridge to cross over to the other track if needed.  It also has a great view of the tracks and trains!
  • Oh, and don't pick the "quiet car" with a bunch of noisy kiddos.  The muffled voice on the loudspeaker will tell you which car is the quiet car.
  • Beware that the train stops for a quick 30 seconds - so have everything ready to go! 

First Stop: Union Station

Union Station is in the heart of LA.  It was opened in 1939 and it is still the hub of LA rail traffic today.


Conversation Starters:

  • Look up at the chandeliers!  Some of them weigh more than a car!
  • Look down at the tiles on the floor - they are made to look like rugs.
  • Point out the "Spanish Revival Architecture" - tall window arches, the browns and yellows with the blues (earth and sky) 
  • If you see a courtyard - step outside!  All the plants in the courtyards are "native".  Talk about the kinds of plants that grow naturally in LA - discuss how there isn't grass and trees with giant leaves.
  • Peer over the wall to the ticket counter. Use your imagination caps to paint a scene of busy ticket takers and crowds of people.  Describe how people would have had heavy trunks instead of suitcases with wheels.  



Next Stop: Fire House No 1 - the Plaza Fire House


This is a great historic landmark that will "wow" the kids while you say "Don't Touch!"  It really is not a hands-on place but it is a quick stop and it's free - you can't pass up free!


History Highlights:

  • The fire house was only in use for a short 8 years 1884-1892.
  • It had housing upstairs for men (you can see a little bed if you look at just the right angle) and 3 horses.
  • After being a fire house (the city apparently never actually owned the land it was built on) it was a saloon, a boarding house, drug store and according to our docent - a house of ill repute. 
  • The turntable on the floor is very neat!  The horses would bring the carriage in and be disconnected and placed in their stalls at the rear of the building.  The the turntable on the floor would turn the carriage around so that the horses could be easily hooked up for the next fire and they would pull the wagon out straight.  Moving the turntable was done by the fire fighters.
  • There is a lot of talk of the Volunteer 38.  This stands for the 38 volunteer fire fighters that worked at this station.  However...they were not so "volunteer" - they actually got paid per the number of fires that they helped extinguish.

Logistics:

  • Once you exit Union Station - you walk across the street and through the square and on the other side is the Fire House.
  • It is free but donations are appreciated.
  • It is open only Tuesday through Sunday 10-3.

Up Next: Olvera Street!


Walking back across the plaza and a little to the left - you will quickly find the brightly colored Olvera Street!  It is filled with carts and stores and restaurants.  It smells good and you can feel the energy!

What to do with kids there?!

  • Eat - we found a little taco stand where we ate some cheap yummy food and were serenaded by a mariachi band (for a tip of course)
  • Shop - plan on spending a few dollars for a souvenir - and I really mean a few!  We brought home a marionette puppet that the kids love for $5 and a little turtle figurine that my daughter just had to have for a $1.50.  We also did a little birthday present shopping and bought personalized guitars for $12 each - but really - can you top a personalized guitar - that is a great gift!
  • Bargain - go ahead and try to bargain.  Bargain out the sales tax or try to buy a few things and drop the price a little. You can bargain so you should - it is always good to practice bargaining and to demonstrate it for your kids.
  • Experience - Look at the old tall buildings.  Feel the vibe of the market and the crowds.  

History Highlights: 

  • Olvera Street is the oldest part of downtown LA. 
  • Originally Settlers had set up near the LA River but were forced to higher ground by unpredictable floods.  The new location grew into El Pueblo de Los Angeles where Olevra Street is located.
  • Olvera Street is the center for Mexican traditions in LA.
  • The Plaza was initially the civic center of LA but as the 1880s brought a new influx of people to the city, the city center was moved it its current location.  Olvera street fell into disrepair and took on a new position of welcoming immigrating families. 
  • It was Cristine Sterling who worked tirelessly to restore Olvera Street and close it off to car traffic.  She secured donations from local brick and cement companies.  Inmates were used to do the hard labor.

And Now - The Avila Adobe House!


The Avila Adobe House is a wonderful place that you can tour for free.

Highlights:

  • In the courtyard - there are beautiful grape vines growing on trellises above your head!
  • There is the actual Avila House that you can tour.  A docent was present to give you a little history.
  • It is remarkable the number of religious items in the house.
  • The house tour ends with a look at a child's bedroom.
  • There is a movie playing in one of the buildings of the courtyard...oddly enough the kids didn't want to stop watching it.

History:

  • It is the oldest standing house in Los Angeles.
  • The walls of the house are built of adobe and are about 3 feet thick!
  • Originally the floors were dirt and would be swept several times a day.  The wood plank floor was added later.

Logistics:

  • It is located about halfway down Olvera Street.
  • It is open every day 9-4.

And that was our trip - we headed back to the train station in time to pick up Starbucks for the ride home and hustled our tired kids back to the train for a fun ride home!

Science in the Park - Oranges and Colors!

This week - we looked at the buency of oranges and at colors. The kids has a blast!

Experiement 1: The Orange

Materials:

  • glass
  • orange
  • salt

Action!

We first started off with a simple orange and a simple question - would the orange float or sink in a glass of water?

Kids think - it will sink!
Experiement says - it floats!


The Science:

The orange peel acts like a life jacket - it has a bunch of tiny air pockets in the peel that give the orange buoyancy in water.

Next Step

Peel the orange and ask the kids now what they think will happen - will the orange float or sink?

Kids think - Sink!
Experiement says - Sink!

The Science:

This one is somewhat obvious. If we took the life jacket off the orange - then it will sink to the bottom of the glass.

A Twist

Add a few tablespoons of salt to the glass and stir. Ask again - will the orange sink or float in salt water?
Kids think - Sink!
Experiement says - Float!


The Science:

The salt changes the density of the water; making the water and salt mix more dense and allowing the orange to float. This can be "kid" explained by saying that the salt mixes with the water to create a salt-water that has more in it to hold up the orange!

Experiement 2 - COLORS!

In this experiement we will be making fireworks while exploring how oil and water do not mix.

Materials:

  • yogurt cup (or other small container)
  • food coloring
  • oil
  • spoon
  • jar with water in it

Step 1

Put a few tablespoons of oil in the cup and let the kids squirt a few drops of food coloring in it.

Step 2

Stir it up! If you skip this step - the colors will not look as pretty.


Step 3

Carefully pour the oil into the jar so that the oil stays on top.


While you watch the colors will fall through the oil and into the water where they will mix with the water and look like fireworks!

The Science:

The oil is less dense than the water - so it stays at the top of the jar. The food color is not so it slips down and then mixes with the water to create the fireworks!!

Enjoy!

Science in the Park - Balloon Science

Today's Science in the Park features balloons!  Since it is HOT out here - we are using some regular balloons to inspire conversation and some water balloons to cool off!

Material List:

  • baking soda
  • vinegar
  • balloons
  • empty water bottles
  • cooler full of water balloons
  • straws
  • scissors
  • tape
  • yarn/string
  • liquids that smell (ex. mouthwash, vanilla extract, etc)

Experiment 1: Smell the Balloon

Preparation: squeeze a little bit of a strong-smelling liquid into a balloon and then blow the balloon up.  We decided to use bubblegum mouthwash, vanilla extract, and lemon soap.

Action!  The kids took turns guessing what was in each balloon. 

The Science: Balloons are made of a porous material that allows the scents to escape.

Experiment 2: Blow up a Balloon

Preparation: Give each child a water bottle. 

Action! Spoon 3 teaspoons of baking soda into the bottle.  Then add about a 1/2 cup of vinegar quickly.  As it starts to fizz - slide the balloon on top of the water bottle so that the escaping gas fills up the balloon.

The Science: The vinegar (acid) neutralizes the baking soda (base) resulting in water and carbon dioxide.  It is the carbon dioxide gas that blows up the balloon.


Experiment 3: What floats?

Preparation: Give each child a tray of about an inch or two of water in it and a water balloon.

Action! Use the air filled balloon from the previous experiment and the water balloon and see which one floats.

The Science: The water balloon sinks while the air-filled balloon floats.  It's a simple observation but it reinforces that the water balloon is heavier than the air filled balloon and that is why it sank.

Experiment 4: Crazy Balloons

Preparation: Squeeze a water balloon into a deflated regular balloon.  Then blow up the regular balloon and tie it off.

Action! Gently throw the balloon and watch it move around like crazy!  Careful - they pop easily!

The Science: The center of gravity of the air filled balloon is in motion because of the water balloon inside moving around.

Break for a water balloon fight!


Experiment 5: Balloon Rockets


Preparation: Blow up a balloon and tape it to a straw.  Then feed a string through the straw so that the straw with the balloon on it can easily glide along the string.  Add a clothespin to the balloons knot for weight.  Tie something (we used leaves found on the ground) to either end of the string so that the straw/balloon cannot slide off.

Action! Fly the rocket!  Start it at the top of the play structures or stand on top of the picnic tables.  Talk about how to make it go faster! 

The Science: This science is physics.  Put the string at a steep angle and notice how it goes faster than at a small slant.

Science in the Park - Egg Science

This week's edition of "Science in the Park" featured "naked eggs"!  Naked eggs are eggs that have been soaked in vinegar for a few days dissolving the hard outside shell to reveal the rubber-like insides.  Since the eggs (although very cool) didn't take much time - we did a repeat experiment of "elephant toothpaste" that definitely "wows" the kids.

Naked Eggs

Preparation

  1. Soak 2 dozen eggs in vinegar for 4 days (no - it won't smell like anything other than vinegar). 
  2. On the night before, gently rub off the remaining "white material" to reveal the naked egg.  I found it easiest to do this under running water.  I started with 24 eggs, but I only got 14 naked eggs (I broke the rest). 
  3. After rubbing off the white material, put the eggs back in fresh vinegar and by the next morning, anything I couldn't rub off had come off by itself. 

Experimenting

Material List:

  • eggs soaked in vinegar (and transported in the vinegar)
  • gloves for the kids so they can touch the eggs
  • food coloring for coloring the eggs
  • recycled yogurt cups for holding the egg
     

Examination

Most of the experiment is just the egg itself - so start off by examining the egg.

Q&A Conversation Starters:

  • Ask: What is missing from the eggs?  When the answer "shell" is given, state that the eggs were put in vinegar for a long time to dissolve the shell.  <The science: the shell and the vinegar have an acid/base reaction!  The shell is made of calcium carbonate and the vinegar breaks it down into calcium and carbon dioxide which are the bubbles that form on top>
  • Ask: If there isn't a shell...then what is holding the egg together?  Mention that when you crack an egg, the egg is runny and liquidity.  The answer is that an egg actually has two membranes that stick together to look like one and then the egg shell is on top of that!  <The science: these semi-permissible layers are called the "outer shell membrane" and the "inner shell membrane" - very creative names - and they are made partly of keratin (the same as your fingernails!) >

Experimentation

Next we colored the eggs by putting the eggs in water with food coloring. After a few minutes the egg turns the same color as the water.
 

Conversation Starters:

  • Osmosis!  Talk about how the water traveled from the cup into the egg by using osmosis to get into the egg and since the water was colored - when the water went into the egg, it turn the egg the same color as the water!
  • Older kids : talk about how the egg is composed of 90% water and so when it is placed in a cup filled with 100% water - it wants to find its equilibrium meaning it wants to be the same inside the egg and outside the egg.  So that is why water travels into the egg via osmosis.
 

Ending


So - now what should you do with the naked egg...

  • Some kids couldn't wait to smash it!  When you break the membrane you get a vinegary runny egg and a membrane in your hard!
  • Some kids (mine!) wanted to take the egg home and let it sit for a few days outside of vinegar.  Then the egg becomes more like rubber and can be dropped and "bounced" a few inches off the ground. 
  • You can also let it sit in the colored water overnight
  • Or - you can soak in in corn syrup overnight to get a dehydrated egg!

Kids Cook - Lemon Garlic Chicken

Kids Cook!

Mom needs a break from the kitchen...so why not turn control over to the kids and let them cook dinner...well with boundaries of course! 

Kids cook is when the kids get together and make dinner for their families!  The best part is that it gives them a sense of accomplishment when Mom and Dad thank them for dinner!
 Everything is prepared ahead of time to make it easy for the kids to cook.

Recipe: Lemon Garlic Chicken

Ingredients

  • Chicken (it can be any type - legs, thighs, breasts whatever.  Personally I use half a chicken for my family so that is a thigh, leg, breast and tender)
  • Potatoes quartered (I used 4 small gold and 6 small red)
  • 2 handfuls of green beans
  • 2-3 Lemons (depending on how juicy they are)
  • 5 Tablespoons olive oil
  • 4 cloves garlic

Prep Work

  • Rinse Chicken
  • Quarter the potatoes
  • Snap the green beans (take off only the stem end of the bean)
  • Slice 1 lemon
  • Juice the remaining lemons (you want about 1/3 a cup of juice or a little more is just fine) and add to the garlic (chopped) and 4 tablespoons of oil - this is the sauce

 Kid's Turn

  • First the kids got a little bit of oil in their dish (about a tablespoon) 
  • They moved their dish so that the oiled covered most of their pan
  • Then make a layer of the lemons
  • Next layer is the green beans
  • The potatoes go around the edges
  • Then the chicken goes on top of the green beans
  • And the sauce goes on top of everything

 Cooking Instructions


  • Put in 450 degree oven for 50 minutes covered.
  • Then take the cover off and cook 10 more minutes.
  • Enjoy!
