Tips for Planning Your Year in Science

  1. Choose two or three topics you would like to investigate.  You can use broad topics or activities you have always wanted to try.  You can let your child choose the topics.  You can let the test book choose for you.  Two or three is enough as you will want the freedom to let your child go further into a topic if it interests him or her.   If you have more than one child, it is easier if you study the same topic together, only on different levels.
  2. Choose the text or reference material you would like to use.  You may decide on a textbook.   Two points to remember about a textbook are:  early science texts are more readers than science references and later texts can get very boring if you use them as the sole guide for the class.  Choose a book for its information, its readability (by you not your student), and its pictures.  The younger children will learn a lot of science if it is read to them and if they can see the pictures as you explain them.
  3. Look through your science experiment books for ideas for hands-on fun.  Sometimes the book you have choosen for a reference has experiments in it.  Sometimes it is fun to use those cute little experiment books for ideas.  Choose experiments to go with  your topics.   Don’t worry about doing every experiment in the book, or every one on a topic.  Just plan for about one a week.  You don’t have to do them on that schedule though and you can add more as your children think them up.  Playing with science is important.
  4. Decide what you want for a product.  Do you want to grade something?  A test?  A paper?  A notebook?  Something aloud?  Or no grade at all?  Please try to keep a notebook.  In the notebook you can have sections for new terms, notes, maps, photos, experiment write-ups, reports, news clippings, speech notes, tests, and activity pages.  This way your child will have something concrete to remember all about his year in science.

Preschool Science: Roly Poly Hotel

By Rachel Paxton, homeschool-articles.com and Christian-parent.com

If you have a preschool-aged child running around your home, chances are he or she has brought in a roly poly or two from your garden.  Because children are fascinated by these little creatures, they make great subjects for science experiments.

Before you and your child begin this experiment, you will need to round up a few items from around your home and garden:

  • Small rubbermaid container
  • Dirt
  • Moist dead leaves
  • Sticks and twigs
  • Medium-sized flat rock

Have your child fill the plastic container about halfway full of dirt from your garden.  Explain to your child that you are trying to re-create a roly poly’s natural habitat.  Where are roly polies found?  They are found under rocks and piles of decomposing leaves.  After the dirt is in the container, have your child place the rock in the container on top of the dirt and arrange the leaves and twigs around the rock.

Next give your child a jar and have he or she collect some roly polies for the roly poly hotel.  This will be their favorite part of the experiment.  After the roly polies have been collected, have them place them in the container.

Help your child create a “sign” with their name on it for their roly poly hotel.  They can create it by hand or on the computer. Tape the sign to the front of the plastic container.

Now that the roly poly hotel is complete let your child sit and observe the roly polies and let he or she hold them and play with them a bit.  Help them make observations about the roly polies by asking them questions. Ask them what the roly polies look like and what they notice about them. Ask them what color they are and how many antennae the roly polies have. You’ll be surprised at the answers they come up with.  My boys told me that the roly polies roll up like armadillos!

If your child is going to keep their roly polies for further observation, have them keep the soil moist and keep the container out of direct sunlight.

If your children are older you can tailor this activity to their learning level.  You could check out a book from the library about roly polies or search for information about them online and do a number of science activities with them.  With preschoolers, however, you’ll find that their attention span won’t last much longer than the observation part of the activity.  After about five minutes of watching their roly polies my boys informed me they were done and were ready to go swimming!

The Butterfly Garden

The butterfly is a beautiful addition to your garden.  Because they can be easily grown and observed, because they occur all across North America, and because they are so beautiful, they are well studied in homeschool.  Here are some ideas for doing a unit on lepidoptera, butterflies.

Start with a trip to your dictionary and look up the words: butterfly, lepidoptera, moth, scales, wings, proboscis, and antennae.  Next, check out a book about butterflies and learn about their life cycles.  Then, go to your garden shop and ask about plants which attract butterflies and about the gardens they love best.  Now you are ready to put together your butterfly garden.

Planning your garden

There are a few qualities a garden should have in order to become a place which will attract butterflies.  The location should be sunny and have some protection from the wind.   Although butterflies look delicate, they are stronger than they appear, but wind will tend to carry them easily past the plants you want them to inhabit.  They do bask in the sun on low walls, log piles, and stones, all places of shelter and sun.  Butterflies have predators as well and low growing shrubs and rocks can provide some protection.

Butterflies need sources of rich nectar and are attracted to plants which smell sweet.  Choose plants like the butterfly bush or the coreopsis which will provide these things by growing beautiful flowers all season long.  The most obvious plants are local wildflowers; for example, honeysuckles, lupines, black-eyed susans, and, in Texas, bluebonnets.  See the list below the post for suggested plants.  In your local area there may not be many of those plants listed here, but do not worry as there are some generic plants which will probably be found either in nearby fields or at your plant store.  Other sources of butterfly attracting plants are mail order suppliers.  Mass plantings of colorful and sweet smelling plants are great for your butterfly garden.  Creeping phlox which cascades over walls is a good attractor as in Spanish heather.

Another, often overlooked plant type which must be present in the garden is the edible plant; edible, that is, for the caterpillars.  When you attract butterflies, they will lay eggs for the next generation of butterflies.  When the eggs hatch, the larvae (caterpillars) must have food so you need to provide for them.  Members of the carrot family, parsley family, lettuces, celery, and other herbs are feasts to caterpillar.  Don’t begrudge them the food because they represent your next group of butterflies.  Host plants will supply many needs of the butterfly in all of its life stages.  Some of these are Butterfly Weed (providing for the Monarch butterfly among others), herbs like dill, parsley, and fennel (which the Black Swallowtail enjoys), and the Tulip Tree (a home for the Tiger Swallowtail).  Willow, clover, milkweed, sassafras, Queen Anne’s Lace, and passion flower are other host plants.

Remember, too, that butterflies are insects and because of this are sensitive to insecticides and pesticides which you may be tempted to use in the garden.  If you need to use something to save your fruit trees or whatever, try to limit the area it may affect.  Only spray the effected area as overspray  will kill your butterflies.  According to the Wise Garden Encyclopedia, even herbicides and fungicides will harm the insects you want to cultivate.

So, now you have a garden which has attracted many different kinds of butterflies.  What do you do next?  Everything is not known about butterflies, their habits, their cycles.  This means that you may discover something important about butterflies.  So, keep a journal on what you see in your garden.  Record the numbers and varieties of the species you see.  Try to answer the questions: what, where, why, when, how, how many, and for how long, in your journal and as completely as you can.  Make colored drawings for your notebook.

Study the behavior of the butterfly. What are the favorite flowers to which each type of butterfly you see is most attracted?  Do they seem to migrate from yard to yard, or even farther?  How long do you notice one butterfly in your yard?

Study the biology of the butterfly: What are the butterflies’ sizes, colors, and flying characteristics?  How do they see and smell?  Can they recognize the colors of the flowers or it is only smell which attracts them?

What are the life cycle stages of your butterflies?  Study the adults and try to find the eggs they lay.  Keep careful watch over the eggs until they hatch, then observe the larvae.  Make sure that the larvae are getting plenty to eat and then watch over the chrysalises they produce.  At the correct time, perhaps ten days, the beautiful butterfly will come out of the chrysalis and begin to fly.  Keep records of the stages and the number of days each lasts in your journal.

Collect more butterflies for your garden: Go out into the field or forest and look for chrysalises hanging from limbs, leaves or rocks.  Collect them carefully and place them into a vivarium (a place for live specimen).  Later, when they come out you can place them in your garden on some good tasting (to larvae) plants for them to grow and mature.  Another way to collect butterflies for your garden is to look for caterpillars to place on the parsley or carrot plants.  Although some of them are not the prettiest thing in the garden, they mature into something of beauty, so remember that when you see them eating up your salad greens.

Observe the four stages of the life cycle: egg, larva (caterpillar), pupa (within the chrysalis), and adult (butterfly).  Make drawings or take photos to record the events.  To photograph a butterfly, you will find it best if you collect the caterpillar and wait it out until the adult emerges from the chrysalis.  For a brief time, the tissues have not hardened sufficiently for flight and the butterfly can be photographed fairly easily.

The butterfly is an insect and so is made up of three body parts: the head, the thorax and the abdomen.  The parts are segmented with the wigs usually coming from second and third segments of the thorax.  The head has compound eyes, segmented antennas, and a proboscis.  This proboscis can unroll into a long sucking tube which allows the butterfly to feed upon nectar.
If you wish to preserve some of the butterflies, catch them with a butterfly net, place them in a killing jar, dry them on a spreading board and pin them, labeled, in a box prepared for the collection.  Be sure to write on a slip of paper pinned with the specimen, the pertinent data:  place found, name of the butterfly species, common name, when the specimen was collected, and by whom.
The homeschooler has an advantage in the study of butterflies since they are usually active during the day.  There are many types of butterflies, over 700 varieties in North America, so there are plenty to study.  Build a butterfly garden, get out that journal, and begin a study of beautiful creatures which can last a lifetime!
