Educate your kids and save the world with worms

Okay, I'm exaggerating about saving the world -- but maybe not too much. After nearly ten years of thinking about it, I am finally a worm farmer. We've had a compost bin for seven years, and we have compost piles all over our farm, but vermicompost is even richer than what you can make in a regular compost bin, so I finally took the plunge. Monday I attended a composting seminar, and at the end of the day I attended a session where we made our own bin and got our worms. I wrote about it on my farm blog.

I've always thought this would make a great homeschool project, and even apartment dwellers can do it. In fact, they should do it, because not only is it educational, but it will use up all of their kitchen scraps and keep them out of landfills. Worms will even eat things that you shouldn't put in a regular compost bin, like gravy and potato salad, which have too much fat in them for traditional composting. Then the vermicompost can be used to fertilize container plants, such as tomatoes and peppers grown organically in front of a sunny window or on a patio.

Now, what about saving the world? Garbage is one of the biggest problems we have facing our society -- really. When I was a reporter in the Chicago burbs, it was one of those topics that cities were always talking about. Landfills fill up, and no one wants a stinky landfill in their backyard, so municipalities are paying more for having their garbage hauled farther away. Solutions like worm bins can help our society.

But who wants a stinky worm bin in their apartment? Worms need oxygen, and as long as your bin has plenty of oxygen, it won't stink. It's an aerobic process, and if your worm bin or traditional compost bin starts to stink, it means you're heading into an anaerobic situation.

And, about saving the world -- it really isn't an exageration to say that educating your kids could save the world someday. It is entirely possible that some homeschooled kid with a worm bin could grow up to figure out a permanent and earth-friendly solution to all of our garbage problems.

InHome Conference 2009

The annual InHome Conference will be held March 5 to 7, at Pheasant Run Resort in St. Charles, IL. Registration is available on-line now.

Katherine and I will be presenting two sessions together. In Bringing Science to Life, we'll talk about many of the things we do that make life science practical. This will be geared to parents with kids of all ages, and we'll have lots of examples of how kids can learn science in the real world, whether you live in an apartment in Chicago or the middle of nowhere.

In Next Step: Community College, Katherine will talk about her first year at a community college, and I'll talk about the experiences of my other children as students at a community college, as well as my experience teaching at a community college.

Katherine and I will each be part of a panel discussion on college and homeschoolers. I'll be on the parent panel, and Katherine will be on a panel for teens. The point of these sessions is mostly to give the audience members an opportunity to ask whatever burning questions they might have about college.

I'll be presenting Preparing for College, where I talk about what your children need to know to succeed in college, from my dual-perspective as a college instuctor and a homeschool mom. I'll talk about the things that my college students are most lacking, as well as what presented challenges when my own homeschooled children started college.

If you're able to attend, please be sure to introduce yourself to us!

Need for science education

As I've written before, homeschoolers are in a perfect position to provide the best science education for their children, because we can take our kids out into the field and do things with them that make science fun and interesting! My daughter who blogs at Science on the Farm is taking her first college science class this semester, and she already said that she can see why most students say they "hate" science. There is a lot of memorization, and without the practical background, it seems pointless and boring. Here's a quote that pretty much sums up a great article on the need for better science education. (STEM is an achronym for science, technology, engineering, and math.)

"What is most dramatic about this survey is the extent to which the Fortune [1000] executives speak with one unequivocal voice on these issues," said Attila Molnar, president and CEO of Bayer Corp. "Almost without exception, they overwhelmingly recognize this country's great need to tap the potential of the entire STEM talent pool, and the importance of doing so at every point on the development continuum--beginning in elementary school with high-quality, hands-on, inquiry-based science education, through college where STEM talent is refined and recruited, and then into the workplace where it must be further nurtured and encouraged."

Yes -- hands-on, inquiry-based science education -- not memorizing anatomy charts and periodic table of the elements. The people in education know what we need, and the executives in businesses know what they need, but the current educational system is not equipped to provide it.

And I especially liked one of the comments posted by a reader:
Teaching "what" to think (STEM content) is insufficient; they also need to learn "how" to think. Too many of our best minds are crammed full of content but don't know how to make the most of the knowledge. We need to push critical thinking, creative thinking, and systems thinking in the curricula even before the STEM (or any other technical field, for that matter) content. It's like having a huge database but no program.

Again, kids need to be out in the field, getting dirty, doing stuff, rather than sitting in a classroom memorizing a bunch of stuff. Even if you live in an apartment without a yard, you can grow plants, keep an aquarium, or have a couple of pet mice. And you can head out to nature preserves, the zoo, and museums. Most good science teachers would do this if only they could, because they know this is how kids learn science. But alas the schools can't afford field trips every week for their students.

Science in the real world

When homeschoolers see me speak or first encounter something I've read, they might assume that I'm a science or math professional. Nothing could be further from the truth. However, I write and speak about math and science a lot more than writing -- I am a writer -- because I had such a hard time with math and science in school. Although my science grades were more consistent than math -- math fluctuated from As to Ds, while I almost always had Bs in science -- I struggled to earn those Bs. Teaching science in the classroom is as bad as trying to teach writing through sentence diagramming. Kids can't learn science without living science. My youngest has a blog where she writes about Science on the Farm. While most people don't have a 32-acre classroom in their backyard, they do have plenty of places to study science:
  • Even a small backyard has plenty of opportunitites to study science. Get a bird feeder and a bird guide for your state and start checking off your visitors.
  • Ask your child to help you decide which plants to put in your flower gardens. Does it need shade or sun? How many hours of sun does each area of your yard get in a typical summer day? How much water does the plant need? What type of soil?
  • Natural areas, such as parks and recreational areas have lots of plants and animals.
  • An aquarium is an ecosystem unto itself and provides great opportunities for kids to learn about aquatic animals and plants.
  • Zoos have programs for kids, such as the Junior Zookeeper program at the zoo in Bloomington, IL.

These are just a few ideas. The most important thing for parents to know is that science is one of the easiest things for kids to learn without textbooks. And having a strong foundation of practical science can make it easier for kids when they go into the college science classroom. When they start seeing all of those scientific names, they have a framework to make it all fit, rather than just trying to memorize a bunch of meaningless facts and names.

What surprises a lot of homeschoolers is that most public school teachers would be doing what we do if they were allowed to do it. Here's a post by a public school teacher in Alaska. He talks about what a positive experience it was to take his students into the woods for 20 minutes. We can take our kids into the great outdoors for hours. But it's a big deal for a public school teacher to do something like this for 20 minutes, because it takes away from the time they need to spend teaching kids what they need to know to pass the standardized tests.
