Field Trip Friday: World of Wonders Science Museum

While compiling my list of 400+ Northern California field trips, I came across a hands-on science museum in Lodi and decided to check it out.

The World of Wonders Science Museum certainly encourages hands-on science discovery. Although situated in busy downtown, the museum showcases a relatively large space filled with dozens of exhibits. Admission is more than reasonable:

Stellaluna (Bats) Unit Study

I'm behind on my posts but trying to catch up!

Post-Halloween, Aidyn and I learned all about bats with a Stellaluna unit study.

Stellaluna (by Janell Cannon) is a sweet story about a baby bat who loses her mother and lands among a family of birds. Stellaluna learns to adapt to her new life as a "baby bird" by eating insects, doing her best to perch upright, and sleeping during the night. When Stellaluna reunites with her own kind, she learns how wonderful it really is to be a bat!

Aidyn loved this story and the touching illustrations of Stellaluna's vulnerable eyes and her wacky face when she tries flying like a bird.

Reading:

We snuggled on the couch every day and read this story. After the first reading, we learned new vocabulary words with a set of cards I printed from a Stellaluna unit study on homeschoolshare.com.

Aidyn acted out each word as I read the definition, and we read back to see how Cannon used the word in her story. Then we played Vocabulary Bingo to practice the words.

The next day, Aidyn reviewed the vocabulary cards and chose a favorite word (clutched) and wrote his own sentence with it.

During the rest of the week, we read other bat-themed books like Bats at the Library and Bats at the Ballgame (both by Brian Lies), Bats (a nonfiction book by Gail Gibbons), Baby Bat's Lullaby (by Jacquelyn Mitchard) and Little Lost Bat (a sad little story by Sandra Markle). Aidyn independently read an easy reader called Batbaby Finds a Home (by Robert M. Quakenbush).

Science:

We were fascinated by bats' keen sense of smell after watching some YouTube videos about bats. Inspired by Delightful Learning, I set Aidyn up for a Batbaby Scent Experiment. I scented about six or seven cotton balls with different aromas and showed him his "baby" and let him sniff the scent. I then blindfolded him and let him try to find his lost baby.

He carefully smelled each baby until he found his own!

This scent activity delighted him. We also talked about echolocation, and he impersonated a bat navigating the night sky using echolocation.

He also watched the cartoon version of Stellaluna on YouTube.

Fun Food:

On the first day, I made Aidyn a bat PB&J sandwich with fresh fruit.

Later in the week, I made  him a watermelon bat and an orange bat.

Writing:

Each day after reading vocabulary cards, Aidyn wrote sentences with his favorite words. We also brainstormed some bat facts, and he wrote about his favorite fact and illustrated it.

Pretend Play:

Prompted by his own imagination, Aidyn donned his Spider-Man bath towel and pretended to be a bat. He called himself a "bean bat," a species he made up apparently. He flew around the house and used echolocation and his sharp sense of smell to collect beans. Throughout the day, he provided me with bean bat stats--their diets of fruit and meat, their habitats, their personality and the fact that they shifted from nocturnal to diurnal creatures depending on if they stayed with humans or not. He also said they were gliders, not flyers, and demonstrated said ability all over the house.

We thoroughly enjoyed our little bat unit study! We're still reading Roald Dahl books, and just finished George's Marvelous Medicine. Aidyn is still honing his reading skills and loving math and ukulele practice.

Here's Aidyn playing the opening music of Super Mario Bros.

We have begun a fall/Cranberry Thanksgiving unit study. Last year we covered Cranberry Thanksgiving and had so much fun we want to do it again. Check back soon to see what we do!

Ancient Egypt Unit Study

The breadth of this unit study lasted close to three weeks, so I will try to remember everything we did!

Geography:

We learned about the geography of Egypt and created a simple map. We learned that the Nile River flows northward and splits off into a delta.

Writing:

We learned about many different ancient Egyptian gods, and Aidyn created his own god: a half-tiger, half-man god.

We learned all about pyramids and what was stored in them.

Reading:

For fun, we read Who's Your Mummy? by R.L. Stine

And Bill and Pete Go Down the Nile by Tomie dePaola

And the hilarious Skippy Jon Jones in Mummy Trouble by Judy Schachner.

Aidyn also learned to read some Egyptian words.

Hands-on Learning/Art:

We made hieroglyph stamps using potatoes. 

We read about how the early Mesopotamians  made cuneiform tablets while the Egyptians made papyrus. We made both to see which was easier to make and which was most durable.

Mixing the batter for cuneiform tablets.

Rolling out the dough.

Carving messages.

Then we baked the tablets to harden them.

We read about ancient Egyptians who used reed to make papyrus. Without reed around, we substituted with strips of paper.

Dipping the paper strip in the flour-and-water mixture.

Laying the strips evenly.

He loved dunking his fingers in the goo.

Afterward we smashed blueberries to make blueberry ink.

I don't have pictures, but we waited for the papyrus to dry and wrote on it using the blueberry ink. The writing was very light at first, but once it dried it was a solid blue-red color. We noted that the papyrus seemed pretty fragile and the coloring could easily be washed away if it water got on it. Cuneiform tablets, though heavier and harder to make, were much more resistant to destruction.

We also constructed our own Nile River. We put dirt in a large pan and divided it down the middle for the river. We lay aluminum foil on the bottom and used rocks to keep it down.

We planted grass seeds along the banks, and Aidyn flooded the Nile.

Again, no pictures, but now our Nile has grass sprouted on either side of it!

World Religions/Mythologies

We read about Osiris and many other Egyptian gods. We also watched some Christian mythologies, The Prince of Egypt and Joseph, King of Dreams.

He watched them both a few times and absolutely loved The Prince of Egypt.

(Gross) Science Experiment:

We peeled and carved seven apples to represent mummies and set them in different variations of preservatives to see which would last the longest. We got busy around this time, so the poor apple-heads were sitting pretty for two weeks.

Isn't he gorgeous?

Not so bad.

He's seen better days.

He was our most eligible apple--a 50/50 mix of epsom salt and table salt did wonders for his skin.

Speaks for itself.

Overall, this was a pretty gross but entertaining (and educational!) little experiment. (excuse the boxes in the background; we're in the process of moving.)

We had a blast learning about ancient Egypt!

We just started a Kindness Project unit study, so check back to see what we do!

First Day of Second Grade: Spelunking at the Moaning Caverns

Although we officially start today, we wanted to begin the school year with a field trip that included David. Yesterday, the whole family drove down to Vallecito, Ca. to go spelunking in the Moaning Caverns. We will be studying earth science for the first 18 weeks so a cavern tour was very fitting.

Highway signs have dotted our region for decades, but this was a first-time experience for all of us. We didn't really know what to expect but were willing to venture below the earth anyway.

The entrance to the Moaning Cavern sits inside the gift shop where narrow, steep stairs descend between craggy rocks. Soon enough, spelunkers reach a iron spiral staircase that reaches 165 feet into the cavern.

Once we reached the bottom, it was astounding how far below the surface we were. There were interesting rock formations with funny names (like the Chocolate Waterfalls).

David snapped this picture while I was in awe of the depth

This is what I saw

Safe and sound at the bottom

This is the bottom of the cavern entrance where our tour guide explained that prehistoric people reached the bottom in only 7 seconds... (bones on display in a glass case by the gift shop)

Barely noticeable, this pool of water creates a moaning echo each time a drop of water falls in it

Aidyn is excited to return for zip-lining, which was closed while we were there. When he's 12, he wants to try rappelling into the cavern, but that looked terrifying from our side! 

All in all, not a bad first day of school although atypical. : )
