Cannonball Jellyfish

Another study from all angles ….

Cannonball jellyfish were strewn all over the beach on Hilton Head Island.

A Few Facts:

  • These common sea jellies do not usually sting humans and are not considered a threat.
  • Unlike other jellyfish, they do not have long trailing tentacles.
  • Leatherback sea turtles are one of their main predators.
  • They feed primarily on zooplankton.
  • Also called the cabbagehead jellyfish, they are commercially harvested for human consumption in Asian markets.
  • Their lifespan is generally three to six months.

Baby Bunnies

When my daughter looked over her deck, she unexpectedly spied a mother rabbit building a nest. The backyard, in her words, now belongs to the bunny family. She will keep me updated. That was all the inspiration I needed to wonder more about the rabbit life cycle.

I didn’t think this nest was well hidden, but according to Braelei Hardt, naturalist with the National Wildlife Federation, “Rabbits nest directly on the ground, often in the middle of lawns, gardens, and landscaped areas. This surprises most people, but it’s intentional. Mother rabbits choose to nest in open, visible locations because approaching predators are easier to spot. The nests are shallow dugouts, layered and covered over with dried leaves, grasses, and the mother rabbit’s hair—easy to stumble across while mowing your lawn or for your dog to uncover accidentally.”

“Rabbits’ nests are often easy to spot, but the mother rabbit is much harder to see. She does not stay at the nest; the babies are left alone,” says Leah Stallings, executive director of Aark Wildlife Rehabilitation and Education Center. “The mother rabbit returns to the nest in the early morning hours to nurse her young. She then leaves the nest but is usually in the area hidden from view,” says Stallings. “She returns in the evening to care for her babies and again leaves them alone for the night—you should rarely, if ever, see the mother.” Notice how camouflaged she is in the photo below.

I look forward to photos of the kits. “The babies grow quickly, and by about three weeks of age, they are weaned and ready to be on their own,” says Stallings.

I own these two charming non-fiction books about rabbit families. Although the illustrations aren’t photographs, they are realistic.

The Why Behind Teaching Science

Some thoughts…

Through my years in education, I’ve seen the time allotted to science (living, physical, and Earth sciences) and social studies (history, geography, economics, and civics) classes cut in elementary schools to add additional time to reading and math blocks.

HOWEVER, less time on these subjects is not what’s best for young children!

Children are sensory learners, driven by curiosity and active exploration, rather than passive receivers of knowledge.

Most of the problems in the world today, such as food insecurity, loss of animal habitats, world relations, climate change, and pandemics revolve around issues related to the sciences. We need informed citizens!

There are well documented health benefits to spending time outside in nature.

These subjects lend themselves to project-based activities with real-world applications, resulting in deeper learning and the development of critical thinking, communication, collaboration, and creativity skills.

Knowledge of these disciplines leads to a deeper appreciation of literature, art, and music.

Research has demonstrated that reading scores actually improve when additional time is spent studying science and social studies! Standardized tests often include non-fiction passages. Children who have greater background knowledge and a broader vocabulary score higher on these exams, but more importantly, read with greater understanding.

I hope teachers are reading non-fiction books to their students and using them in small groups, not just during a science lesson. Cross curricular instruction is the most effective and as I stated in a previous post, many children prefer informational books.

And engaging science lessons create JOY!

Note: More science does not mean additional time reading science textbooks and completing worksheets! Also, although I am a major advocate for STEM, I need to caution about STEM activities replacing time dedicated to science. The scientific method focuses on understanding natural phenomena, while the engineer design process attempts to create solutions to real-world problems. Both are important. Engineers use their knowledge of science, technology, and math.

My New Favorite Books!

There is nothing like an engaging picture book!  Research shows that many children prefer non-fiction over fiction. The illustrations in the following books will immediately draw you into them. They are extraordinary! Scientists of all ages will be fans!

I discovered the first three books in the children’s section of the Georgia Botanical Garden gift shop:

“From the best-selling illustrator of Flip-a-Feather, Mix-a-Mutt, and Flip-o-saurus comes another book with charming artwork and die-cut pages for flip-and-flop fun―this time with insects! Build-a-Bug lets you create wacky combinations of ten types of insects, including a curious beetle, a climbing caterpillar, and a buzzing honeybee. Each flap includes a fun fact about the pictured species, and inside the front cover is a chart showing the real-life sizes of the insects featured, from the ant to the praying mantis.” (Amazon)

Build-a-Bug - ACC Art Books UK

“From creation of the “compost cake” to curing and, finally, using the compost, budding composters will discover what it takes to have a successful bin―as well as the plethora of benefits a compost bin can have to the surrounding environment.” (Amazon)

Inside the Compost Bin, (Hardcover)

Inside the Compost Bin by Melody Sumaoang Plan, Vinh Nguyen, Rong Pham ...

“Featuring foil-stamped illustrations that accentuate the intricacy of spider-web designs, The Secret World of Spiderwebs is a remarkable, beautiful, and spine-tingling tribute to spiders.” (Amazon)

The webs glisten on these pages!

Thanks to StarrMatica for recommending the following two selections:

13 Ways to Eat Fly” is playful STEM picture book that explores how different animals capture
and consume flies, combining science, math, and humor.” (Amazon)

“Perfect for kids who are fascinated by insects and American history, The Spider Lady, a little-known hero of World War II, collected and bred spiders in her home and found new ways to use their silk to help the United States win the war.”  (Amazon) What a remarkable biography! Watch full screen.

Wren Photography recommended this new picture book. The author’s brother is the illustrator.

The Weedy Garden is a debut picture book that invites readers to explore the vibrant ecosystem of a wildlife friendly garden. Nan Renki creates a rich tapestry of life in the garden.”

A Gentle Reminder

I wrote this post three years ago, but I am reposting it with some additional thoughts and resources. I saw this photo first on Facebook. It really struck me. Just look at how the woman in the middle is savoring the moment. She is present. Being present means being fully aware of what is going on around you.

I think we miss so much. On my Greenway hikes, I’ve been surprised at the number of people distracted by their phones with so much beauty around them. I would have missed this if I hadn’t been present.

Be still and know that I am God. Psalm 46:10

Slow Dance, by David Weatherford.

You’d better slow down.
Don’t dance so fast.

Time is short
The music won’t last.

When you run so fast to get somewhere
You miss half the fun of getting there.

When you worry and hurry through your day,
It is like an unopened gift thrown away.

Connecting Environmental Science and STEM

This truck caught my eye. I’ve never seen a combo truck for both recycling and trash before and how fun that it is pink! However, wouldn’t it be great if the recycle side was larger than the trash compartment?

I often walk on the Big Creek Greenway which is a floodplain, and frequent flooding has resulted in the deterioration of the paths. As a result, large rocks were placed alongside the trail to prevent erosion, but I realized that these are actually broken chunks of sidewalks. What a clever way to repurpose them!

The terms recycle, reuse and reduce are familiar to most of us, but I also love the idea of reimagine. In the links below, you will find many ways to reuse and repurpose those items that would ultimately land in your recycle bin or your trash can. Try these STEM activities with your students or children!

The Beauty of Ice

Snow is something many of us look forward to in the South, but not ice! Ice brings power outages, dangerous driving conditions, and fallen trees, especially the top-heavy pine trees. Do you know the difference between sleet and freezing rain? Watch full screen.

Well, freezing rain arrived and I took a quick walk outside to capture the beauty while trying to ignore the damage to my garden.

Include a cooking activity with your study of ice at home or at school. Fun choices would be popsicles, shaved ice or an icee.

Young scientists will enjoy excavating ice. Use a plastic container and fill it with small toys – such as a Lego or plastic animals. Then fill the container with water and carefully set it in the freezer. After the water freezes, remove the block of ice from the container. What could you use to chisel the ice away?

Living Things Lab

I am the science enrichment teacher for learning pods at the ColLab. After observing the skulls of deer and comparing pinecones and evergreen needles, we investigated roly polies. A preassessment provided insight into our background knowledge of pill bugs.

Facts We Learned:

Pill bugs, also called roly polies, potato bugs, and isopods, are not bugs at all, but crustaceans and therefore related to shrimp, lobsters, and crayfish. They are the only terrestrial crustacean.

Roly polies breath through gills and must consequently live in a damp habitat. They are more active at night.

When threatened, pill bugs roll into a ball. Armadillos use the same defense mechanism.

Pill bugs have 14 legs (seven pairs).

They grow by molting a hard exoskeleton.

As decomposers, they eat rotting vegetation on the woodland floor.

Eggs are carried in a pouch under the female.
