When we turned a corner in Venice and discovered a musician playing the glass harp, I was able to check an item off my bucket list. It was such a delight to see this in person! Such artistry!

Go here to watch her play.

Might be fun to try this investigation at your next dinner party or family meal! There are numerous ways to add to this investigation. Collect a variety of goblets, give your student or child a pitcher of water, and let the discoveries begin!

Is It a Frog or a Toad?

Do you know the difference between frogs and toads? After watching the video, try to identify the amphibians below.

In general frogs have a longer body and legs made for jumping, while toads are squatter and hop or walk. The skin of a frog is smooth and moist, but a toad’s skin is bumpy and drier than a frog’s. Toads have poison glands behind their eyes (note the photo above), so their eyes are not as bulbous as a frog’s eyes. Frogs live close to water because they breathe through their moist skin, while a toad uses its lungs, and can therefore live further from water. Frogs also tend to be brighter in color. Both frogs and toads lay their eggs in water, but frogs lay them in clusters and toads in strings. Click here to see the eggs we had in lab. Amphibians go through metamorphosis during their life cycle.

This decomposing frog, gifted by a student, illustrates the length of a frog’s legs.

A Study of Lily Ponds

If you are visiting a pond or studying pond life, be sure to include lily pads as part of your investigation. This aquatic plant thrives in full-sun and grows in still shallow water or at the edge of a deeper body of fresh water. I snapped these photos at Western Lake in Watercolor, Florida.

The rounded notched lily pad leaf has a waxy coating and repels water. Stomas, openings in the leaves, help the leaves float and exchange gases. Lily pads appear to be freely floating, but they are attached to a stem that extends down to where it is rooted at the bottom of a lake or pond. These perennials reproduce by producing root-like stems called rhizomes.

Many water lilies open from early morning to mid-afternoon, but others bloom at night. Blooms last three to five days.

Sometimes thought to be invasive, the leaves provide food and shelter for aquatic life and shade which lowers water temperature and reduces algae growth.


Seeing these animals, reminded me of The Little White Duck, a traditional children’s song.

Claude Monet, a French impressionist, is known for numerous large paintings of his lily ponds.

Another story to connect art, reading, and science:

The giant water lily can be found at the St. Louis Botanical Gardens.


I was surprised to discover water lilies in Montana!

Add plastic lily pads and pond animals (such as these) to your child’s pool, bathtub or in a water table for hours of fun!

Apple Study

Fall food is my favorite – apples, pumpkins, and butternut squash! North Georgia mountains are well known for their apple orchards and my family visits an orchard annually. Click here for an apple orchard field trip with my first-grade botanists.

There are numerous ways to integrate the study of apples with other subject areas. Click here for an oxidation experiment with apples.

Integrate math with science and weigh apples and other objects with a balance scale. Click here for directions.

Then explore the concept of balance using the story, Ten Apples up on Top. Place an apple on a child’s head and direct him or her to balance it as he or she walks across the room. How many apples can you balance on top of one another like the characters in the story? Ask your students to work in small groups or create a balancing apples center. Use this rhyming story to introduce or practice the concepts of more, less, and equal, as well as addends that equal 10.

Love this musical version! Click here for full screen.

Taste a variety of apples or a red, yellow, and green apple and create a tally, pictograph or bar graph of your students’ favorite apples.

Celebrate apples with an apple tasting party (apple butter, apple pie, apple sauce, apple cider, apple turnovers, and apple muffins). Make apple sauce or apple crisp.

Estimate how many seeds are in an apple, and then cut the apple to reveal the star inside. Cut several more and count the seeds. Do all apples have the same number of seeds? Does one variety of apples have more seeds than another? Be sure to use the correct terms to describe the parts of an apple – skin, core, seeds, stem, and flesh. Of course, apples can be used to introduce fractions.

There are many engaging apple stories! Use The Seasons of Arnold’s Apple Tree to learn about the life cycle of an apple tree. Sequence the life cycle. Click here to watch full screen.

Acorns

Leaves aren’t the only things falling from the trees around my house. The oak trees are also dropping acorns. Not only are acorns the seeds of the oak tree, but they are also food for animals, such as deer, mice, wild boar, squirrels and opossums.

The hundreds of species of oak trees result in a variety of acorns. Just look at the diversity-color, shape, and size!

 

If you see small round holes in acorns, acorn weevils are present. In the fall, the fully grown acorn weevil larva chews a hole in the side of the nut and emerges.

This story illustrates the interdependence of living and nonliving things in creation. Also, a great lesson for cause and effect and sequencing. Click here to watch full screen.

Sing The Acorn Song with your students. Instead of clapping, make a clicking sound with your tongue. Click here for the tune.

I’m a little acorn brown,
Lying on the cold, cold, ground.
People always step on me,
That is why I’m cracked you see!
I’m a nut (clap, clap),
I’m a nut (clap, clap),
I’m a nut (clap), nut (clap), nut, (clap, clap).

I’ve been watching the acorns grow on oak trees around my home since spring. Just think, everything the tree needs to grow is inside the acorn! Acorns don’t appear on an oak tree until it is mature, usually around twenty years old.

Acorns change from green to brown and their caps (cupules) fall off.

Collect acorns and try to germinate them. Do a little research before you begin. Some acorns should be stored in the refrigerator first, while some species of acorns can be planted right away. Place the acorns in water. Floating acorns will not sprout and should be discarded and composted. Why?

Play “Where is the Acorn?” as you teach positional words. After giving each student an acorn, give them commands. Suggestions:
Put the acorn in your left hand.
Hold the acorn behind your back.
Place the acorn between your fingers.
Lay the acorn under the table.
Hold the acorn in front of your face.

Progress to multi-step directions.
Turn around, jump two times, and balance the acorn on your head.

Play the following game to develop self-control and observational skills:

Choose one student to be the squirrel. Other students (squirrels) sit around the selected student in a circle. The teacher places an acorn behind the squirrel while the squirrel’s eyes are closed and then points to a child to quietly take the acorn and hide it in the student’s lap. All students also pretend to be hiding the acorn in their laps. Children repeat, “Squirrel, squirrel, look and see. Someone took your acorn. Who could it be?” The squirrel is given three chances to guess who removed the acorn without leaving the center of the circle.

Grizzly Bears

When my husband and I were in Yellowstone and the surrounding areas, we were frequently reminded that encountering grizzly bears was a real possibility and warned not to hike without bear spray.

I saw two bears from a distance but was unable to photograph them. These photos were captured by my friends, Susan and Ted, who live in Montana.

Felt as if I was on a bear hunt which reminded me of one of my favorite children ‘s books. This story is easily dramatized and it’s always fun to add sound effects using your body, common objects, or instruments. Use this book as an engaging way to teach positional words (under, over, and through) as well as descriptive words (long and wavy), and onomatopoeia (sound words). I have made a map of this story on a long sheet of bulletin board paper with prior classes to introduce map skills and to retell and sequence the events.

Bumblebees vs Honeybees

I recently posted about honeybees, but how do they differ from bumblebees? Although they are both insects with six legs and three body parts, there are many differences between the two species.

Honeybees are domesticated and produce honey, while bumblebees are always wild and produce a minimal amount of honey. The bumblebee body is large, round and furry while the honeybee is much thinner, and its four wings are distinct. Most bumblebee species prefer to make hives underground and the colony is smaller than the above ground hives of the honeybee. A bumblebee can sting multiple times, unlike a honeybee that can only sting once. Only the queen bumblebee will survive the winter, but the honeybee colony will remain intact through the winter months.

Look at those compound eyes! See previous post about insect eyes.

There are more species of bumblebees than honeybees, and of the two groups, they are the better pollinators. Using your knowledge of their bodies, why do you think this is true? Observe bumblebees at work.

In a past lab, we pretended to be pollinators. Sugar water (nectar) was in the cup and “pollen” rubbed off the Cheetos (stamens) onto our hands, like it does on a bee’s legs. The straw was our long tongue that we inserted inside the flower.

Praying Mantis

I spied a praying mantis as I walked through my garden.

A praying mantis is a carnivore. The mantis will grab its prey with those front legs. Gardeners are a fan!

Do you know what is unique about the head of a praying mantis?
