Turtles

We are still doing our weekly science co-op with 2 other families and I've really neglected posting about it. We are doing Exploring Creation Zoology 2: Swimming Creatures. I am thankful to have 2 other creative moms to teach with and we really seem to compliment each other in our teaching strengths. And, we have a great group of 8 kids! I'll try to do better keeping up with our (usually) weekly meetings, as I think we have some great resources to share.

This post on turtles is from back in December and it is only from one of our 2 meetings. Here are some of the things we did:
From this site we drew our own diagram of a turtle's carapace. We also discussed scientific terms like "vertebral", "costal", "dorsal", etc.


We played an Adventure Game from Euroturtles. It's a great survival game which demonstrates how hard it is to survive as a turtle. Not all of your baby turtles will survive in this game! (Since we have so many kids, I made a large board for this - you could even do a chalk drawing outside - and we only played 4 kids at a time.) This game can also send you "backwards" and we were very proud of one of our little girls who kept being sent back yet stuck in the game. It was a great lesson in sportsmanship!

You can also play this game online! You can play the full version which starts with the mother turtle trying to lay her eggs on the beach, or the shorter version which starts after the eggs have hatched. After trying these games of chance, you might try the Brain Game version where you get to make some decisions and see how they affect your turtle.


While half (4) of our kids were playing the board game, the other half played Once Upon a Beach (scroll down to page 9). This is another neat game where you learn how hard it is to survive as a sea turtle. And, again, not all of your baby turtles will survive!
We made our own paper plate turtles from this site. I actually just threw these out yesterday and didn't realize I hadn't taken any photos. They turned out so cute!

Journey North: Mystery Classes

I have wanted to participate in Journey North's Mystery Class Project for several years and have decided to do it this year. This year's mystery starts on Monday when you'll record your own sunrise & sunset time and determine your local photoperiod. Then, starting on Friday, you'll receive clues to your 10 mystery sites.

I like this project because it not only uses science, but also math, geography, and research skills. Possibly more! I haven't decided if we'll try to determine all 10 mystery sites or keep it smaller since it's our first year. Also, this project is geared to a classroom setting where each group of 2-3 students are only trying to find one of the mystery classes.

To prepare, we will be doing a few projects early in the week. I'll try to get them done on Tuesday (if it isn't too cloudy) so I can post about them.

We will also be learning more about what causes the seasons using this Sunbeams and Sundials site. And, I've just requested a few books from the libary.

Has anyone ever done this class before and can offer some tips? Or have you blogged about what you've done in past years? If so, please let me know. I'm a little unsure of what I'm doing, but ready to jump in this time. (Update: I just found where Melissa at Here in the Bonny Glen posted about these mystery classes last January. She wrote a wonderful post!)

Anyone want to join us on this mystery???

Where in the World is Mrs. Waffenschmidt?

We started something fun for geography this week. It's called "Where in the world is Mrs. Waffenschmidt?" There are 36 lessons and each lesson gives you a clue. Using the clues, you are supposed to figure out the name and location of each of Mrs. Waffenschmidt's trips. Here is clue #1:

Yesterday, I decided to get on a plane and take a trip. I found myself in a wonderful place. One of the most amazing things I saw was a huge white building that looks like a palace - but it's really a tomb for a dead woman! Seems when the man's wife died, he was so upset he wanted to build her the most beautiful tome in the world. The architect who designed it was "rewarded" by having his eyes pulled out! (Some people say his hands were crushed too.) Whatever really happened, it was done so the man couldn't build another building to rival this one. I am in a city called Agra. Can you tell what famous tourist place and country I am visiting?

We used google and I had Alexandra figure out some key words. She chose "white tomb Agra." Then, we looked at the results: Mrs. Waffenschmidt was in India visiting the Taj Mahal.

We read a few short articles about the Taj Mahal and found out this tomb was actually for the THIRD wife of the emperor. This surprised me as he built this tomb because he was so greif-stricken... and it wasn't even his first or his only wife.

My brother, "the world traveler" as I like to call him, has visited the Taj Mahal. So, I asked him to send me some photos - and he did! What's neat about the photo below is that he took it in a mirror. The emperor had a mirror built by his palace in Fort Agra so he could his wife's resting place from the palace.

My brother has been to 3 of the first 5 destinations (I've peeked and looked at the answers) so he's sending me photos from those, too. I think it'll make it more personal.

So, we're reading the clues, googling, reading about the destinations and looking at photos. We also need to find it on a map. I'd like to do something to keep, too. Maybe a lapbook or something. Any ideas???

Brainpop

Alexandra "rediscovered" BrainPop today. We don't have a subscription, but they have quite a few FREE videos. And, they're great! They also currently have an entire section of FREE videos and activities about Winter & Snow. What a fun way to learn!

Giant Pandas (Day 5)

The giant pandas at the San Diego Zoo were so beautiful. And, as with the rest of the zoo, the animals seemed well taken care of.

First of all, there was this sign at the entrance. And, people were very respectful and quiet. In fact, on our bus tour the guide told us that she would have to be off the microphone while driving by the pandas - and that she couldn't even use the brakes because the sound would bother the pandas. There were ropes up for long lines, but we were able to get right in.

There were 3 pandas all together - 1 in the first enclosure and 2 in the second. As you walk by the pandas, there are 2 lines - 1 in the front and 1 in the back. But, the back row is higher so you can see over the other people. First, you walk in the lower, closer line and then you "snake around" to the back, higher level. There is a lady speaking very quietly on a microphone telling you about the pandas. (And, I am sure she is there to make sure people stay quiet, too.)

The pandas looked so cuddly!

This panda was lounging in a hammock.

We watched this giant panda eating a snack - bamboo, of course!

San Diego Zoo (Day 5)

One of our favorite days in San Diego was the day we went to the zoo. We stayed there for only about 7 1/2 hours! It was a beautiful day and it is an incredible zoo.

One of Alexandra's favorite things at the zoo was the sky tram. Even though there was a fairly long ride, we rode it 4 times!

Here's my nephew, baby H, enjoying the petting zoo.

When we first got to the zoo, we took the bus tour. It helped us to learn our way around some. And, we were able to get a great view of some animals.

A camel - also from the bus ride.

And a warthog.

This heron was a "wild" bird. There were a few herons and LOTS of great egrets just hanging around the zoo.

a cute monkey

We really enjoyed watching this gorilla. This was the large male and he was really active. One great thing about the San Diego Zoo is how wonderfully they enrich the lives of these animals. They give them lots of toys. They don't feed them at the same time, or even in the same order, every day - so they never know when food is coming. The grounds are also just beautiful with plants and trees everywhere.

If you can enlarge this photo, please look at this gorillas hands. They are so human like! (And, no, I don't believe gorillas evolved into humans. I believe God created us separately. But, his hands are very like ours!)

We enjoyed watching this black monkey with her little white baby. They were kind of hidden and I don't think many people noticed them. But, if you knew where to look you could see them pretty well.

This was another bird that was flying around "wild." We saw it in other places besides the zoo. I believe it is a dark eyed junco, though it isn't something we see here in Texas. I just thought he was so cute!

And, this parrot was sitting close to the pathway, so I got a good shot of him. I thought it was one of my best shots at the zoo. Isn't he a beautiful bird?

We really enjoyed the pandas, too. But, I thought I'd make them a separate post.

La Jolla Cove (Day 4)

On Day 4, Alexandra and I went back to La Jolla to explore some more tide pools.

I liked seeing this sign about the tides, weather, etc. I enjoyed looking at a calendar that posted the high and low tides. Approximately every 24 hours, there is a high and a low tide, but they are all at different heights.

These are the rocks we walked on at La Jolla Cove. (This is just a few blocks away from the seals.) If you'll notice, the tops of the rocks are light grey while the rest of the rock is kind of brown. It's kind of sad, but these grey spots are where people walk and have killed all of the moss, etc. I was really nervous walking at the tide pools on the first day - there were some very slippery spots! But, after walking all over these rocks, I got pretty comfortable.

Another sea anenome - I could just sit and watch these, even though they aren't doing much! :-)

I need to look these up again, but I believe they are tube snails.

A pelican and some sea gulls. We saw TONS of pelicans!!!

I believe there are 7 caves in La Jolla. You can actually go kayaking into the caves!!! We decided not to do this, but Alexandra and I almost made it to the one "real" cave that you could walk into from a store. We just ran out of time! It is just about a block from this spot.

This is on the beach at the cove. You can see how the water has been cutting these caves out of the cliffs.

And, Alexandra playing in the waves! I enjoyed watching a man swim in the water and then emerge on this beach. And, we watched 2 SCUBA divers climb out here, too.

Scripps Aquarium (Day 3)

I literally took several hundred photos while in San Diego, so I'm really trying to narrow it down. On day 3 we went to Scripps Aquarium.

This is the first camera I've ever owned that has an "aquarium" setting and I'm just amazed at the quality of photos I can take at an aquarium!

This was a neat tank demonstrating a kelp forest. The kelp forests are the type of environment right off the coast in San Diego. One of the videos said they planted the kelp in this tank, but the other plants have all grown from the small plankton that were floating in the water. (In the corner are Alexandra, baby H (my nephew), and my mother-in-law.)

I was fascinated by some old videos of tuna fishing. They literally had 3 or even 4 men all pulling on fishing poles to pull out one of these large tunas! Somewhere around San Diego, we saw a large version of this small sculpture.

And, the 4 of us locked in a Shark Cage - mil holding baby H, Alexandra, and myself.

Seals (Day 2)

One of the highlights of our trip to San Diego was going to La Jolla to see the seals at Children's Pool. Children's Pool was built to allow a safe place for children to swim. But, the seals took over the spot and so it has become a wonderful place to view the seals. (The 20 or so dark "spots" are the seals.)

I found it interesting, as we were preparing for our visit, that some websites said there were seals at La Jolla, some said sea lions, and some said both. Well, we saw harbor seals so I'm still curious - do sea lions really come to La Jolla? Or do people not know the difference? We have been using Exploring Creation with Zoology 2: Swimming Creatures this year, so we were happy to be able to tell the difference. One of the main differences is that sea lions can kind of "walk" on their 2 front flippers and tail, while seals kind of "slither" more like a caterpillar. Also, seals have ear holes, while sea lions have ear flaps. (These seals were sure enjoying the sun!)

We only saw seals swimming a few times. We actually watched a few come on shore and a few leave, but most were content to bask in the sun.

This seal was our favorite - mainly because he was the closest. We walked out almost to the end of the walkway (see top photo) and he was lying on those rocks by the walkway. So, he was only about 15 feet away from us. I took lots of photos of him. Sometimes he'd stick out his tounge or move a bit or scratch himself. (No, I don't really know if it was a boy or girl - I'm just calling him a "him.")

But, I was really sad to see a hook in his mouth when I looked at him with the zoom lens. Can you see it? It's on this side by the corner of his mouth. You can see a short piece of wire curling around a few times, too. But, it does look like it has probably been here for some time and the seal is doing fine. (Also, you can note his ear "holes" - another sign that these are seals.)

Cabrillo National Park Tide Pools (Day 2)

The next morning, one of the things we did was visit the Cabrillo National Park - just in time for low tide. And, it was a very low tide. In fact, they were expecting their lowest tide of the year in only 3 days! I have never seen a real tide pool before and this was one of my favorite parts of the entire trip. I was suprised at how hard it was to get around on the slippery rocks, though!

Above is a chiton - it is a mollusk with 8 hard plates.

This was one of my favorite finds. It is probably about 4 or 5 inches long and is a Key Whole Limpet. Limpets browse on algae along the cliffs and some return to a "home" spot during low tide.

This is a green sea anenome. There were LOTS of sea anenomes around. I'm glad someone pointed one out to us as we arrived, or I would not have recognized them. When they aren't in water, they close up and they're covered in little pieces of shell. (This one is partially closed.) The volunteer told me they are covered in shell to prevent themselves from being dried out!

On the left is a green sea anenome which is opened, and on the right (the whitish "tube") is a tube snail. The tube snail starts its life with a coiled shell, but as it grows, the shell straightens.

(I got a lot of my information froma sign they had near the tide pools.)

A photo of Alexandra out on the slippery rocks. I was really timid at first, but my sil kept helping me along. After awhile, I was getting around pretty well!

Goose-Neck Barnacles - I was surprised at how big there were -

they were bigger than a quarter at their base.

My sil and Alexandra, who were both usually ahead of me!

Another sea anenome which is out of the water and therefore closed.

It looks like it has a round bone in its center! Can you see how easy these would be to miss unless you know what you were looking for?

Hopefully you can find this fish. (His face is towards us in the lower, middle of the photo) My sil found it. It is a sculpin, a "master of disguise." He was probably about 4 inches long.

I should have probably enlarged this, but this is one of MANY hermit crabs we saw. They were one of the few "active" animals we saw.

In the back are California Mussels - filter feeders. Hiding in front is a little Lined Shore Crab.

More Goose Neck Barnacles - they were everywhere.

And, my absolute favorite "find" - a sea star!!! The volunteer told me it was a knobby sea star and that they don't see them very often around this beach anymore. Unfortunately, the photo doesn't show the colors as well as in real life. He had beautiful blue spots with yellow, raised centers. Gorgeous!!!
