Balance

Squirrels often join me on my walks through the woods. They are the ideal animal to springboard lessons about balance. How do squirrels maintain their balance as they leap among branches?

Mollusks

Mollusks are invertebrates which means they have no bones. They are soft-bodied. There are three classifications:  cephalopods, gastropods, and bivalves. In the last post, I shared information about octopuses which are cephalopods. In this post, I will focus on bivalves and gastropods.

Bivalves and gastropods are born with shells. The shells grow with them. Shells are not actually homes but body parts. The mantle produces the shell from calcium carbonate.

Bivalves, such as oysters, clams, scallops, and mussels, have two shells that are hinged together. The shells grow from the outer edges and both shells must grow at the same rate. They can open and close the shells as they move and eat.

Look carefully, do you see the growth lines around the shell? It may remind you of growth rings on a trunk.

Gastropods, such as conch, snails, and whelks, live in a spiral shell. The spiral grows from the outside and wraps around the invertebrate as it grows.

Classifying is an important skill. If you collect shells on a beach holiday, ask your child to sort them. They may choose their own categories which may include size, color, like kind, and texture, but then suggest that they group them into bivalves and gastropods.

Seashells by the Seashore is an engaging book to learn the names of common shells. Click here for the Safeshare link. I gave a bag of the shells to my scientists and as the characters discovered shells on the beach, my students picked up the matching shell. If you go to the beach, try to find these twelve shells.

I made these years ago to integrate science and math for my youngest scientists. I used sandpaper to make the shore.

Inchworms – Math and Science

I discovered this inchworm climbing up my window frame. An inchworm isn’t a worm at all, but the larval stage or caterpillar of a geometer moth. All moths go through metamorphosis-egg, caterpillar (larva), pupa (cocoon), adult (moth). Inchworms are about an inch long and are commonly brown or green.

Do you see the six legs near its head? All insects have six legs. The inchworm’s name is derived from the way it arches to propel itself forward. Ask your children to move like an inchworm. Start in a plank, walk your feet toward your hands, and then walk your hands forward. Repeat.


Inch by Inch is an excellent book to teach beginning measurement skills. Cut green paper into inch strips (inchworms) and use them to measure items at home or in your classroom. Click here to watch the story.

Spirals

I believe in teaching with a multidisciplinary or cross-curricular approach (integrating subject areas) rather than teaching subjects in isolation. STEM also follows this methodology. I’ve found that students consequently reach a higher level of understanding, develop stronger connections, and see real-life applications. The following is an example of how standards can be chunked around a theme. In this case, it is the study of spirals.

How does the study of spirals connect with math? Click here for the Safeshare link.

Before you watch this, brainstorm where you see spirals in nature. Click here for the Safeshare link.

I am reposting links to past labs that focused on spirals found in nature.

I recently wrote posts about conifers and ferns. Add spirals to your study of these plants.

A vortex is spiral shaped. Click here to go to the lab.

Many shells are spiral shaped. Don’t pass by those broken shells!  Click here to go to a lab about shells.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Use loose parts you find to form spirals. Create spirals with patterns too. When you visit the beach, arrange shells and driftwood into spirals.

Turn spirals into snails or snakes.


From the Artful Parent

Doodle with spirals. Use this activity to teach the elements of design, such as line and space. Make large spirals with chalk outside on concrete sidewalks or driveways.

Cut paper into strips of various widths and lengths. Roll them around a cylinder, like a pencil, and place them inside a box with shallow sides. This would make a simple collaborative project and it is a fun way to strengthen hand muscles.

If you have any additional ideas, please leave them in the comments section.

In Honor of 2.2.22

It’s almost 2.2.22! (Hope you wear a tutu!) Enjoy the Veggie Tale song, Come in Twos, Click here.

LYRICS
The best things in life come in twos
Like salt goes with pepper
And carrots with peas
A sock with its mate
Macaroni and cheese
A cup and a saucer
A pair of shoes
The best things in life come in twos
Its cookies with milk
And ham with eggs
Two birds of a feather
Your arms and your legs
It’s making “wes” out of “mes” and “yous”
The best things in life come in twos
The best things in life come in twos Two o o o o o s

Try to add another verse. My new lines are:  a hamburger with fries, and glasses with eyes

The following activity is a fun and creative way to make a connection between math and language on this unique date. Create a class poster about the number 2 on an anchor chart with multiple answers to the sentence starters below or let your students choose a number and design their own number signs.

First brainstorm words, phrases, or expressions that are associated with each number. For example:

One – Uno, single, unicycle, solo, only child, one of a kind, penny, one in a million, all in one piece, one and only, one of those days

Two – double, tutu, pair, twins, duo, twice, bicycle built for two,

Ten – decade, dime, decimeter, decagon, Tennessee, tennis

The pictures below were made by my students almost twenty years ago!

Note: ‘Also known as’ could be a math expression. For example, four could be known as 2+2, 1/3 of 12, or 8/2.

Reading the entertaining story, 7 Ate 9, would be a perfect way to begin or end this lesson. Humorous puns about numbers fill the pages.

Great BACKYARD Bird Count

The Backyard Bird Count is scheduled for February 18-22. This is an easy and fun citizen science project for all ages! I have it on my calendar.

Click here to learn all about the Backyard Bird Count. There is information about a free webinar too.

From their site: (The link in this photo is not active.) Step 1 – Decide where you will watch birds.

Step 2 – Watch birds for 15 minutes or more, at least once over the four days, February 18-21, 2022.

Step 3 – Count all the birds you see or hear within your planned time/location and use the best tool for sharing your bird sightings.

Snow Experiment

A Simple Investigation:

Scoop snow into a tall clear cylinder. A vase or mason jar work well. In my science lab, I used a graduated cylinder. Measure how much snow is in the container. (Many children have difficulty using a ruler.) Leave the container on your counter and check back periodically. Make careful observations. After the snow melts, measure how much water is in the container. Analyze your results. What are your conclusions? Introduce a variable, and place identical jars in different spots, like a sunny window. Would you have the same results with different types of snow?

To extend this investigation, leave the jar on the counter and observe how quickly the water evaporates.

Snowflakes

Watching snowflakes is enchanting! The activities below connect art, science, math, and reading.

Click here for the Safeshare link.

“Snowflake Bentley” (1865-1931) was fascinated by snowflakes and in his quest to share their beauty discovered a way to photograph snowflakes in the early 1900s. Click here to see Snowflake Bentley’s photographs. Click here for the Safeshare link of Snowflake Bentley.

Snowflakes are beautiful, pure, and white,
And like God’s children,
No two are alike!

I tried to capture some photos of snowflakes. I’ve found that a material that is dark and water repellant, like a garbage bag works best. I need a better camera, but I had a little success.

Cutting snowflakes is always fun! Trace a circle on a piece of paper with a plate or other round item. Fold it in half. Then fold the half in thirds, so it looks like a pizza slice, then you will have six sections.

Click here for the Safeshare link to learn another method to make a six-sided snowflake.

Make giant snowflakes with larger paper.

Click here to watch real snowflakes form.

It’s also fun to make snowflakes with pattern blocks. These snowflakes were made by former kindergarten students. There are six pattern block shapes – square, triangle, trapezoid, rhombus, parallelogram, and hexagon. Each student began with a hexagon which has six sides, like a snowflake. Two trapezoids or six triangles also make a hexagon.

Winter Solstice-Information and Celebrations

Winter solstice, the shortest day of the year, is one of my favorite days because from this day forward, daylight will increase in Atlanta. This year, the winter solstice falls on Tuesday, December 21st.

According to Britannica, “We know that seasons are caused by Earth having a slight tilt on its axis. As Earth wobbles around the Sun, different points of the earth receive more or less sunlight throughout the year. If Earth wasn’t tilted, the Sun would just shine directly on the Equator all year long, leaving us without seasons. But we also wouldn’t have solstices or equinoxes. Solstices designate the point where the Sun’s path in the sky is the farthest north or south from the Equator, which occurs around the 20th and 21st of June and the 21st and 22nd of December. The summer solstice marks the beginning of summer and is the longest day of the year, just as the winter solstice marks the beginning of winter and is the shortest day of the year. But which solstice happens on which day depends on the hemisphere you live in.” Click here for the entire article.

Click here to watch a video about the winter solstice.

Around the world, many cultures celebrate this day with ancient traditions. I am a fan of the Tinkergarten Program. Click here for their family winter solstice celebration suggestions.

To connect science with math and geography, check a weather app on a regular basis to discover when the sun rises and sets in your location. Record the data and graph your results. Determine how many hours of sunlight you experience each day. Many students find calculating elapsed time challenging.

Comparing when the sun rises and sets in several different cities is another relevant activity. Find the locations you check on a map and analyze results based on the city locations.
