Turtles Teach: Springtime Science!

The weather is warming up, the sun is starting to shine (sometimes) and flowers are starting to bloom! All of this makes a wonderful combination to do some science! In this project we’re going to create rainbow flowers.

White flowers Supplies

What you’ll need:

  • white flowers, like carnations
  • small jars
  • water
  • food coloring
  • paring knife or scissors
  • tape
  • adult assistance or supervision

Step One: Trim the Stems

Trim the stemsCut the stems of the flowers so they are 10-12 inches long. (Have an adult help!) Using a sharp knife carefully cut a 6 inch slit through the bottom of the stem. Remove any large leaves. Be sure to keep the cut edges moist since exposure to oxygen will make the flowers wilt at a faster rate.

Step Two: Add Dye

DyeFill your jars with water and add between 10-20 drops of food color (or more depending on your preference). Place each separate stem end into a cup of colored water. Prop up the flowers so they don’t fall over. We had some fancy mason jar covers, but tape should work as well to help prop the flowers.

Step Three: The Waiting Game

Waiting gamePlace the jars by a window and hopefully you will begin to see the first hints of color after a few hours, but wait 24 hours to see an even more dramatic change.


What’s Happening?

Flowers go through a process called transpiration, where it releases moisture into the atmosphere. As moisture is released, more water is pulled up through tiny tubes in the stem called xylem. Water molecules have the tendency to stick together, so as one water molecules leaves the flower, it brings another one up with it.

 

Did you like this activity? Then you might be interested in our single-day Spring Break Camp!

Turtle Bay will be offering single day camps April 11th – 13th for children 7-10. Campers can register for one, two, or all three days. Each day will be different from the next as we cover matter, energy, and forces. All camps will feature hands-on and self-led activities that encourage collaboration and innovation.

Tuesday, April 11th – Magnificent Matter

With all things hot and cold, campers will discover the states of matter and how they’re important to us. Some activities include changing milk into one of our favorite desserts to stacking liquids on top of each other!

Wednesday, April 12th – Energy in Action

Campers will explore the sights, sounds, and properties of energy in many forms. From discovering the power from the sun to watching the effects of sounds, we will be learning all about the power or power!

Thursday, April 13th – Fantastic Forces

Though our superhero forces may be lacking, there are still many super forces to be explored! Campers will check out the unseen forces of our Sundial Bridge and see if they can explain the mystery behind magnets.

Whether you have enrolled into one of our camp programs before, or if this is your first time hearing about them, we invite you to check us out! For additional information and registration forms, visit www.turtlebay.org/learn/camps. We have a limited space, so hurry!

From the Vault: Water, water everywhere!

California residents know that when it comes to precipitation, it is often a matter of feast or famine. Currently, Redding is experiencing the feast after a relatively dry spell. We wanted the drought to end but not, you know, all at once! At 79,000 cubic feet per second, releases from Keswick Dam are the highest they have been since the El Niño/La Niña cycle of 1997-98. Heavy rains have flooded valley towns and aging infrastructure is threatened. We are, however, lucky this isn’t 1862. In that year flooding was terrible. A United States Geological Survey paper confirms newspaper accounts that the Sacramento Valley was a 350-mile long, 20-30-mile wide lake!

Here at Turtle Bay, we are perfectly poised to watch the Sacramento River as it rises and falls with each controlled change in the release level and with every rainstorm. The plaza under the Sundial Bridge is underwater, but that has happened a few times since it was completed in 2004.

February 13, 2017. The sign you can see in the 2011 photo is completely under water in the 2017 image.

The Turtle Pond on the trail on the north side of river is currently part of the river and last week the river began flowing over the south trail for the first time since it was paved, filling the wetlands behind the museum.

The South Trail was impassable on February 14, 2017

Before Shasta Dam, this area flooded regularly. One of the dam’s primary purposes is to control those floods. The flood of 1906 washed out the old Freebridge, south of the current Cypress Street Bridge. It was rebuilt and then damaged again the following year. Floods in 1909 and 1913 affected the roads and rail lines. High river flows in 1915 threatened to take out the Diestelhorst Bridge while it was under construction.

While Shasta Dam was being built, Redding experienced its last major flood, the devastating Flood of 1940. On February 28, 1940 the city was cut off by the floodwaters. The storms that month caused the river to peak at more than 185,000 cubic feet per second at the dam site. In his 1997 article for the Covered Wagon, engineer Clair Hill cites a 189,000 cfs maximum flow. Hill also noted that he remembers driving south to Sacramento through water two feet deep on Highway 99. On February 29, 1940, the Oakland Tribune reported that the river was up to six miles wide in some places near Redding. I have heard anecdotal reports that the water crossed the buffer of floodplain farmland and reached the downtown Safeway on Cypress and Market streets.

The east abutment of the old Free Bridge washed away, the abutments of North Market Street Bridge were damaged, and both ends of the Diestelhorst Bridge were under water, effectively cutting off vehicle traffic both north and east. The new rail trestle over the river was badly damaged as well.

In a 1994 Covered Wagon article, John Fitzpatrick recounts pushing a “borrowed” flat car of dairy products north across the trestle to replenish communities, such as Buckeye, that were completely cut off from the food supply. Sadly, that car was also used to ferry back the body of 19-year-old Irene Clement who had drowned in Salt Creek as the result of a car accident. Fitzpatrick reports that on the return trip, the trestle began to buckle as one of the supports gave way. They abandoned the flat car and carried Irene back to Redding.

As we know from this February, Shasta Dam only controls river flooding; it does not prevent it entirely. Nor does it prevent downstream flooding from heavy rains or localized flash flooding. River flooding severe enough to make news across the state has occurred many times since 1940. For example, the San Bernardino County Sun reported a 70,000 cfs release in January of 1953 that flooded homes, ruined a new dance hall, and flooded the Riverview golf course. In February of 1970, the Red Bluff Daily News announced that 14 northern counties, including Shasta, were to receive Federal Disaster Relief funds as a result of heavy flooding. The El Niño of 1983 brought February flash floods and high releases, as reported in the Santa Cruz Sentinel.

What’s the moral of this story? Pay attention to the weather because Mother Nature bats cleanup and chin up, it could be 1862!

Turtles Teach: What is Dry Ice?

Known for its spooky fog and subzero temperatures, dry ice is a mysterious and fascinating substance… but what is it?

dry ice

Everything is made of matter. Matter can exist in many states: solid, liquid, or gas. For instance, water can be liquid, solid (ice), or a gas (vapor or steam). We can change the state of matter by changing the environment that matter is in. You may know we can change water’s state just by changing the temperature. To make water into ice, we freeze it! To make water into a gas, we boil it! However, temperature is not the only factor that determines a substance’s state. Pressure is just as important. Water can be in all three states in normal pressure (1 atmosphere or 14.7 psi); this is not the case with dry ice.

Dry Ice is not made with water, but carbon dioxide. You may know carbon dioxide as a gas, the gas we exhale when we breathe. It too can freeze and change into a solid, but our freezers at home can’t do the job. Special factories use extremely low temperatures and high pressure just to make it. The extremely cold and pressurized carbon dioxide is brought to normal pressures and will solidify into dry ice. This ice is -109 degrees F. But what makes dry ice so fascinating is its ability to sublimate (Sublimation is when matter changes from a solid to a gas). At normal pressure, dry ice cannot be a liquid. When it “melts” it turn directly into carbon dioxide gas! You may see the fog that comes from its icy surface, but carbon dioxide is a clear and colorless gas that we can’t see… The fog is actually the result of water vapor in the air condensing from the cold gas, similar to your warm breath meeting the icy cold air during the winter. When dry ice is added to water, the carbon dioxide gas bubbles up to the surface quickly making the water look like its boiling.

Matter comes in all shapes, sizes, colors, temperatures, and states! Dry ice is just one of the cooler substances.

Hope you learned something new, from your favorite educators at Turtle Bay!

The New Bee Exhibit

To update the blog from last year, I will show how the beehive exhibit finally turned out.

Dr. R. Boyd fabricated the wooden case of the Kiosk. The challenge was to fit in the electronics, get the Kiosk to look nice, tamperproof the Kiosk, and have everything work:

q1

We screwed the Kiosk onto the side of the current Beehive exhibit. It has a leg (visible at lower left) to add more support and stability. In the picture I am tightening the bolts that hold the Kiosk.

q2

As can be seen above, the Kiosk is nearly self contained. It holds the computers to run the monitors, the wires to connect the computers to the monitors, and the wires to connect trackpads to the computers. We have those zipties to make all of those wires neater.

There is even a powerstrip to provide electricity. The only input it needs is electricity for that powerstrip!

When it was finally installed, it turned out great!

q3

The Kiosk feels like an integral part of the original exhibit due to its colors and the use of repurposed wood. It also provides access to a plethora of information for everyone, regardless of prior knowledge.

The Kiosk contains 232 slides about the bees and allows the visitor to explore topics from a variety of levels, from beginner to advanced. It delves into the properties of a beehive, like the one at Turtle Bay, and how to make sense of what you see in the hive and beecam.

Speaking of the beecam, it turned out to be a wild success!

 

It was no problem to weld it together, and it provides a beautiful view of the entrance.

(This photo is not from the Beecam, but is similar to what it would show)

The beecam view is routed into this wall monitor:

q7

It makes plainly visible the exterior beehive entrance from within the warm and cozy museum, even on cold and rainy days.
In the spring the hive will be renewed and there will be plenty to see and explore!

Things to Do in 2017

In case you are looking for something to do with you little ones while the big kids head back to school, or are wanting to provide fun learning opportunities for your children… Turtle Bay is a good place to start! Turtle Bay is already a place for interactive, exploratory fun, but did you know about some of our regular programming that is available to you? As the New Year starts, we invite you to join us as we experience the following programs this year.

Little Explorers

Little Explorers
These little ones got an up close meet and greet with Virginia, the box turtle.

Every Thursday morning, little ones ranging from 2 to 5 years old come with their families for the Little Explorers Program. This program facilitates a play-based learning environment where young children can investigate, create, and discover. Because Little Explorers is in the Mill Building, you can join in rain or shine. A typical program usually includes a story, an activity, and a take home craft all led by one of our docents. January’s theme is Nighttime Wonders. Join us in February to learn all about what’s On the Farm!

Family Second Saturday

Family Second SaturdayIt’s in the name! Every second Saturday of the month, we invite everyone in the family to join us for an afternoon of interactive and educational fun. Although we offer new and exciting activities each month, we occasionally pull out some of our popular favorites! Keep an eye on our calendar for upcoming Family Second Saturday topics and activities; we hope to see you and the whole family there!

This month’s Family Second Saturday: Dry Ice Investigations

February: Innovations

Science Saturday

Science Saturday
Chemical Reactions come in all colors and sizes! Here we have colored Alka-Seltzer tablets being dissolved in warm and cold water. Do you think they had the same reaction?

Following our family Saturday program, each third Saturday of the month we feature Science Saturday. During this event, guests will have the opportunity to experiment, observe demonstrations, and hopefully will be able to answer the question, “What is going on?” as we explore and investigate.

This month’s Science Saturday: Science of Small

Science Saturday
How many glass beads in each glass do you see? Hint: there’s 3 altogether. Come see us this Science Saturday and find out what is going on!

February: On the Ranch

 

We hope to see you here soon!

Shasta County’s First Mini Maker Faire

Trilogy Challenge
During the faire, Trilogy Architecture hosted the “You Shall Not Pasta!” Bridge Building Challenge. Students from Cypress show off their pasta bridges before they are tested.

November 12th was the first Shasta County Mini Maker Faire. With 100+ vendors, over 2000 attendees and countless opportunities to create, this event met all of our expectations and more! Here are some highlights and pictures from the faire.

Bridges

Loom
Turtle Bay’s very own loom gave many makers the opportunity weave yarn to create a textile.

The Shasta County Mini Maker Faire was an opportunity for makers from all over North State and beyond to come together to not only showcase their passion, but to celebrate and inspire creativity, collaboration and hands-on experiences. This event was geared to be family-friendly and we are excited to share that over half of our attendees were under 18! We hope to continue this celebration as our younger community members are inspired by our local makers, educators, parents, and enthusiasts to build, design, innovate, and create.

Set up
Finalizing all the details before the participants arrive!

Although many of the activities provided by our makers are more difficult to recreate than others, we couldn’t help but to give you some ideas and activities you could do at home! Stay connected with the our maker community by following us on Facebook. Happy making!

North State Giving Tuesday is almost here!

Did you know we must raise over $1,000,000 each year to keep Turtle Bay operating? We rely on the generosity of our community to keep the Park serving as a safe, educational gathering place for all families in our community. If we charged admission that covered our expenses (without fundraising) admission would be about $40 a person – and that simply won’t do!

So we fundraise! This time of year, we send out holiday mailers. The past few years, we have raised about $10,000 for the park through generous people who mail back checks. These unrestricted funds help us with everything from keeping the lights on to booking exhibitions to feeding the animals!

Redding Bank of CommerceAlso, for the 2nd year, we are participating in the Shasta Regional Community Foundation’s North State Giving Tuesday. We hope whether you love the exhibitions, cultural and science educational programming, animals, gardens or trails, you’ll include Turtle Bay in your selected charities through www.northstategives.org.

United WayNSGT is the best time to support Turtle Bay as Shasta Regional Community Foundation is offering a variety of incentives to deepen the impact of your gift! Shout outs to Redding Bank of Commerce and United Way of Northern California for making these possible!

Donate online on Nov. 29 from 6 am – 6 pm

In appreciation for your donation of $20+ online to Turtle Bay on Giving Tuesday, we have some pretty amazing incentives:

  • Automatic entry into a raffle to win a 1-hour Family Photo Shoot + digital photos by Heather Armstrong Photography in Wildlife Woods with an Animal Ambassador!

A limited-edition Turtle Bay Wonder-Full foil temporary tattoo – the perfect little stocking stuffer! temporary tattoos

  • PLUS, if we hit our goal of $12,000, our President & CEO Mike Warren will be dunked in the dunk tank aka Visible River Aquarium! Watch on Facebook Live or at the Park on Wednesday, Nov. 30 @ 3:30 pm.
