Here’s the October Edition of the Simple Science Strategies Blog Carnival!

Follow Me on Pinterest

Welcome to the October 31, 2012 edition of the Simple Science Strategies Blog Carnival!

I delayed publishing for a few days, as I know many of my readers have been struggling with weather-related issues, in the wake of Hurricane Sandy and the Superstorm that followed. I pray that all are safe and sound and back to full power soon, if not today.

Thank you for participating in the October Edition of the Simple Science Strategies Blog Carnival!

 

Changing Seasons

Kim Bennett presents Signs of Autumn: Our Trip to the Orchard posted at A Child’s Garden, saying, “We took the opportunity to enjoy a beautiful autumn day and pick some tasty apples, in the process! We could have filed this under “Fruits and Seeds,” too.”

 

Fruits and Seeds

The Bennett family then follows up with Two Easy Apple Experiments posted on Squidoo, saying, “This lens was an extension of our apple orchard field trip (see “A Child’s Garden”), and was fun to do for some “kitchen counter science.””

 

Potpourri

freelee presents “Be a Backyard Scientist” posted at 52 Days to Explore, saying, “Botany, biology and other sciences in the back yard with simple items you may have.”

That concludes this edition. Thank you to all participants! Each submission earns a free copy of “Autumn Leaves: A Plant Study,” a 23-page science journaling e-Book for studying fall leaves.

Cause and Effect: Using a Multi-Flow Map in a Science Center

Follow Me on Pinterest

Why Study Cause and Effect?

Scientific investigation and experimentation is all about connecting things. In  order for students to connect two events, or a treatment and its effects, students have to understand that things stay the same, unless acted upon by something else, and that things have the ability to change the behavior of other things.

Understanding cause and effect is a complex skill, involving many subskills:

  • Direct observation of objects and their attributes
  • Observation of objects through the use of simple tests and tools
  • Connection of two events
  • Making predictions based on facts, observations and past experiences
  • Evaluation of the probability and possibility of past and future events, based on observations, the body of scientific knowledge and past experiences
  • Understanding and communication of scientific ideas in words, diagrams and writing
  • Understanding causality and correlation

In short, the understanding of cause and effect, and communication about it, is at the heart of scientific experimentation and investigation.

Tools for Communication Cause and Effect

David Hyerle has established a system of eight Thinking Maps to organize thinking around distinct cognitive processes. One of these maps, the Multi-Flow Map, is specifically created, by the learner, to demonstrate cause-and-effect relationships. (Please click on the link, below, for resources prepared by Wappinger Central School District, in Fishkill, New York, for teaching about the Multi-Flow Map and using it with students:

The Multi-Flow Map

The Multi-Flow Map: useful for demonstrating an understanding of cause and effect relationships.

Using a Multi-Flow Map in the Classroom

This month, we have been using some typical October events to teach questioning:

  • the formation of fruits and seeds from flowers
  • fall color development
  • bird migration
  • changes in the weather

Here are some ways that you could use a multi-flow map in a science center, to provide independent practice in showing cause and effect. Provide the object identified, blank observations sheets and the directions for making a multi-flow map (see the link, above). Leave “cue cards” with the words “What happened here?” and “What will happen next?” Provide a basket for completed work, or create a class bulletin board for students to combine all their thinking into a classroom display (use different colored cards for causes, the event, and effects, and connect with string — leave a stapler at the bulletin board to facilitate student independence).

Fruit and Seed formation

  • an apple with a poke in the side
  • a cut or bitten apple that has begun to discolor
  • an apple with a bruise or rotten spot
  • a photograph of a chipmunk with full cheek pouches
  • a photograph of a blue jay with an acorn in its beak

Fall color formation

  • a branchlet with leaves in different stages of color development
  • a skeletonized leaf
  • a leaf with scorched leaf margins
  • a leaf with sooty mold, powdery mildew, or leaf spot
  • a leaf with insect galls

Bird migration

  • a photograph of geese in V-formation
  • a photograph of blackbirds congregating near a feeder
  • a photograph of vultures climbing a thermal
  • a photograph of goldfinches or other bird in transition plumage

Weather changes

  • a photograph of flooding after Hurricane Sandy
  • a photograph of a tree on downed power lines
  • a photograph of houses collapsed on a beach after a hurricane
  • a photograph of a person chopping wood
  • a photograph of wood smoke coming from a chimney
  • a photograph of  a pile of student jackets on the playground

A Note About Centers

Whenever possible, use real objects, and any relevant tools, instead of photographs or pictures. When photographs or pictures are used, make them relevant to the students. For example, after our experiences with Hurricane Sandy,  I would photograph downed trees or flooding in my town, or the school’s flooded playground, instead of another location. Always use whatever has the most meaning to your students.

From Apple Flower to Apple Fruit

On Stability and Change: The Apple

This month, we are studying the concepts of stability and change. The first of our nature-based studies involves a favorite autumn topic in New England: apples.

The apple: a great opportunity for year-round botany study. (c) Kim M. Bennett, 2012.

Apples present an excellent opportunity to study stability and change, in both spring and fall, where we can study the transformation of the bare tree to one with leaves, the emergence of leaves and flowers from buds, the growth of apple fruits from the spent blossoms, the gradual ripening of the fruit, and the ultimate dropping of fruits and leaves as the fall winds down to winter.

This is also a nice opportunity to begin to talk about the structures of flowers and fruits, using the familiar, and accessible, apple, even during the winter months. Use the Apple a Day” notebooking pages, for these, and other, activities.

A Year of Studies, by Season

An apple tree, all year round

Using the “Adopt-a-Plant” strategy, choose an apple tree (or, if you do not live near one, a crabapple tree will do), and observe it very early in the spring, before the leaves emerge (March or so, here in New England). Sketch the tree, or one branch on the tree in one frame, and provide a narrative to accompany each drawing. Add additional pages, as necessary. Here are some questions you might use as prompts for sketching and writing:

Winter (March)

science strategies apple tree flower botany

Sample page. This frame and lines journaling page is useful for multiple sketches over time, or multiple views.

  1. Sketch a bud on a twig. How are the buds protected in the winter? Carefully dissect a bud. What do you see inside?
  2. As the bud opens, what parts of the bud remain? What happens to the other parts? Why do you think this happens?
  3. Notice the markings and scars near the buds. What do you think cause them? Explain.
  4. Count the number of nodes from the tip of a branch to the trunk. How old is the branch? Explain how you figured this out.

Spring (May)

science strategies apple tree flower botany

Sample page. Botanical drawings and content vocabulary for journaling, word study, vocabulary building, or penmanship.

  1. Sketch an opening bud. What parts do you see first, the flowers or the leaves? Do they come out at the same time? Do all buds produce leaves and flowers? Describe what you see.
  2. Draw an opening apple blossom. Label these parts: stem, stipules, calyx, sepals.
  3. Sketch an open apple blossom. How many petals do you see? Draw the calyx behind the petals. What shape is the apple blossom? Color your drawing. Are the petals the same color on the inside as the outside? Why do buds and the blossoms appear different colors?
  4. Draw an open apple blossom. Label these parts: petals, stamens, filament, anther, pistil, stigma.
  5. Have an adult help you cut open the base of the apple blossom. What do you see inside? What do you think these become? Use what you know about apples to help you answer.
  6. Carefully sketch the arrangement of the new leaves as they grow around the blossom. What color are they? Do they stay this color?

Summer (June)

science strategies apple tree flower botany

Sample page. Diagrams with labels, or boxes for labeling. Pages with and without word banks as a scaffold for labeling.

  1. Sketch a twig or blossom after the petals fall. What parts remain? What parts are missing? Why do you think some parts fall off? What part do you think becomes the apple fruit that you eat? What becomes the seeds?
  2. Use a piece of colorful tape to mark one twig with developing apples. Return to sketch one developing apple, once a week. Identify any parts of the original blossom that remain.
  3. How many apples grow from one winter bud? How many leaves? Draw a branch and show the arrangement of apples and leaves.
  4. Does the apple branch keep on growing? What part grows after the fruit forms?

Fall (September)

science strategies apple tree flower botany

Sample page. Woodcuts from botanical texts: useful for rendering accurate colors when observing.

  1. Sketch three apples of different varieties, making sure to render the shape accurately. Describe the differences and similarities in these areas: shape, stem, color.
  2. Observe a ripe apple on a tree. Notice the color. Is it the same color everywhere? Develop a hypothesis about the role of air temperature and sunlight in the development of apple fruit color.
  3. Carefully draw and color one apple. Is it the same color everywhere? Are they spots or streaks? Is it the same color on both sides?
  4. Draw a ripe apple (outside and inside views). Identify the flower parts that created the structures you see.
  5. Use words to describe the texture of the apple skin. What function does the skin serve? (See Experiment 1)
  6. Cut up apples of five varieties. Create a data table to compare and rate them from 1-5 based on these factors: color (1=greenest skin, 5=reddest skin), texture (1=coarsest pulp, 5=finest pulp); crispness (1=crispiest, 5=softest), juiciness (1=juiciest, 5=driest), taste (1=most sour, 5=sweetest), aroma (1=no aroma, 5=strongest aroma).
  7. Cut apples of several varieties from stem to flower end. Draw and compare the core area.

Winter (December)

science strategies apple flower botany

Sample page. A variety of lined pages, in both regular rule and primary rule, for copywork, handwriting practice, observations or thematic writing.

  1. Gather an apple, a pear, a peach, a plum and a cherry. Carefully cut each in half, starting at the stem end. Sketch what you see. What is the same about all these fruits? What is different?
  2. Cut an apple from end to end, along the core. Sketch what you see. Note the core line. Can you connect the stem to the flower end through the core? Why?
  3. Cut another apple across the core. Sketch what you see in this view. Identify the flower parts that formed what you see. Draw the seed cells. Can you see faint dots between the cells? What do you think these are? How many seeds do you find in each cell (carpel)?
  4. List all the apple varieties you know. Use other resources to find more names. Sort them by use, color, country of origin.

Two Experiments

These experiments are adapted from The Handbook of Nature Study (Anna Botsford Comstock), where you can get many other ideas for prompts for botany journaling or classroom discussion, as well as great background information for you, the teacher.

Experiment 1. The role of the apple peel

Take three apples of similar size, shape, and soundness. Peel one. Place the peeled apple on a desk or shelf. Place one of the unpeeled apples so that it is touching the peeled apple. Place the remaining unpeeled apple on the other side of the peeled apple, but at a distance, so it does not touch.

Which one would you predict would rot first? Which one would you predict would rot next? Where would the rot start? Why do you think this?

Develop a hypothesis to explain your thinking. Explain what you think the role  the skin serves in the life cycle of the apple tree.

Observe the apples for rot over the next several days. Evaluate your hypothesis.

Experiment 2: More on the role of the apple peel

Take the rotten apple from the first experiment. Use a safety pin or a needle to prick the flesh of the rotten fruit, then use the juice-covered pin to prick a healthy fruit. Go back and forth, pricking the rotten fruit once, then pricking the good fruit, making your initials in the good fruit. Put the inoculated apple on a desk or table. Throw away the rotten fruit or compost it.

Develop a hypothesis about where rot will begin on the inoculated fruit.

Observe the inoculated fruit over the next several days. Note where rot begins. Explain why you think this is so. Also relate your findings to how apples should be handled at the orchard, in shipping, and in the grocery store, to ensure long shelf life.
