Book project on the human body--from the archives
I was looking through old TWIOC posts, and it looks like I never shared with you all something Becky and I did for the preschool kids one time when she and I were in charge of childcare for the morning SoulFood Bible study. Since we were going to have our kids with us, we decided to make the most of those hours every week by doing a unit on the human body. I just wrote about it on my blog, so if you are interested, please feel free to hop over and take a look. : )

snowflake art--wow!
I just saw this posted on another homeschool blog, a beautiful project for anyone still interested in studying snow this year. . . (myself, once Christmas is over I get into Spring mode. : ) So I think I will file this away for next year--but isn't it beautiful? And what amazing chemistry must be going on behind the scenes, which would be fun to figure out.

Plastic in Our World: Day 8
With your kids
1. Watch the short video, The Story of Bottled Water.
2. Talk about the idea of marketing: how companies try to persuade us to buy their products. Then watch these bottled water commercials (here and here) and discuss them as marketing strategies. (If your kids are like mine, they will think the commercials are fantastic. Which makes the discussion all the more interesting!)
If you like, compare those with this commercial, that shows a very different kind of bottled water. Excellent fodder for discussion about luxury versus necessity; wise, just, and compassionate ways to use money; and human rights.
3. Find a couple of magazines and have your kids look through them to see if they can find any bottled water ads. If you can, talk about the imagery, words, implied fears, desires, etc. in the ad. If you don't find any bottled water ads, speculate about why you didn't--what does that tell you about how the bottled water industry sees the audience of that particular magazine?
(My kids looked through Parenting magazine, and did not see any bottled water ads, which suggests moms are wise to those scare tactics by now. ; ) But we did find an ad for a new product--tablets of sugar, artificial color, and artificial flavor that your kid can drop into his/her glass of tap water so that he/she will then want to drink it. We talked about the subtle implications in the ads--that plain old tap water tastes bad, that your kids won't drink water without incentive, that artificial flavored and colored sugar water is just as good for you as plain water--that tried to create a need for their product.
Studying advertizing is always fascinating, and I don't think we can start educating our kids soon enough on the lies culture often tells us--esp. when someone wants something from us.)
Your kids might get really into this whole reading the messages in advertizing game--a fun thing to do when out and about!

Week 1 "Growing Greener Challenge": Eliminating Microbeads
Take a look at this article and consider eliminating any products you use that might contain plastic microbeads. These microbeads are so tiny they are even worse for our world than those durn nurdles--the microbeads are ingested by creatures so small that they work their way up the whole food chain. And to make matters more directly harmful to humans, the microbeads even manage to get through municipal water treatment systems--ending up in tap water.
Scary, no?
The good news is that there are plenty of more natural products that can be used instead--this article lists some, and gives resources for further investigation. And if you choose to up the Greenness and try an alternative that comes without a plastic container, you still have options! For example, baking soda is awesome for scouring when cleaning. And you can buy all kinds of beautiful, natural exfoliating facial soap bars online if you can't find them locally.
Anyone up for the challenge? Please post a comment to let us know what products you are using or plan to use instead of microbeads, to encourage others. : )
Plastic in Our World: Week 1 Reflection and Action

The key ideas for our family were that there are positive and negative things about plastic--plastic itself is not necessarily bad, but it is good for some applications, and not good for others. Also, some characteristics of plastic, like its long life, can be both good and bad. Similarily, all the ways we use plastic are not necessarily bad--but can be wise or unwise.
With your kids
1. Summarize some of the negative qualities and/or applications you have learned about plastic. Older kids can do this in their Plastic Research Journal (see Day 4).
Then summarize some of the positive.
To help brainstorm, use the list at the bottom of this article as a starting point. Or go back to Day 1's observations about how you use plastic in your own home. A couple of the things my family talked about were the ways doctors use plastics to help repair people's bodies--like hearts and joints. And in places in the world where the local water is not safe to drink, plastic bottles or bags of purified water can be a necessity of life (albeit not a permanent solution!).
2. When your one week of plastic collection is up, take the box/bag to the driveway or someplace where you can dump it all out and take a good look at what you have accumulated (don't dump in on grass, as you might lose small pieces). Observe the kinds of plastic your family seems to be using up and throwing out. Consider if these reflect wise or unwise use of plastic. If you determine together that some of your plastic waste is unnecessary, brainstorm alternative solutions.
3. Discuss as a family how you can together make one positive change in how you use plastic, and then start doing it. (See our family's list below, or check out Fake Plastic Fish for LOTS of ideas.)
Be sure to re-bag your Week 1 plastic trash collection--you will want to save it for one more week. But this is the time to start a second collection for Week 2, in a separate bag/box.
The guy who made the documentary "Addicted to Plastic" said it well; let's not demonize plastic, but instead treat it as the amazingly versatile, valuable product that it is. It comes down to being wise in our understanding and use of it. Wise is not making it just to throw away (as in all single-use applications, like disposable dinnerware). And some plastics are not as safe as we would like to think, and should not be used in some of the ways we routinely use them. And if everybody just made one small change in how we use plastic unwisely, it would add up big time.
Thanks for being a part of our first week's study! Please keep coming back for the second week, and lots more info and ideas. : )
Website of the day
Watch this free PBS documentary to see how scientists can use all that trash floating in the ocean (bad) to learn more about the ocean's currents (good)!*
Five ways our family is changing our plastic lifestyle, for the better:
--Choosing not to use plastic for storing food, whenever possible.
--Now that it is summer, using fresh tomatoes in all recipes, instead of plastic-lined cans of tomatoes.
--Buying produce at places where we can take our own bags for it, like the farmer's market or places that have bulk food.
--Being very careful when shopping at places that overpackage produce, like Trader Joe's.
--Choosing to go without personal items that come in plastic packaging (like shampoo and facial scrub) whenever possible.

Plastic in Our World: Day 5
There is one more way in which plastic affects our world and the creatures that live in it:

Okay, so that is not plastic. But it is natural oil, from which much of the world's plastic is made. It can be found deep under the ground, in enormous deposits. Oil has been an amazing resource for humankind for a long time, and is used for everything from fueling our cars and airplanes to making plastic. But when people dig to get the oil out, sometimes they make mistakes, and oil gets out into the natural world.



This article is one journalist's perspective of what it is like to be in the water with the oil, and helps the reader imagine what it would be like for the animals who live in the water.
This article gives an excellent overview of the details of an oil spill--and is clearly enough written that older (high school) kids will be able to follow it.
This article talks about all the kinds of things we use oil to make--a fascinating list!--and a few of the ways we can be wise about our dependence upon petroleum products.

Plastics in Our World: Day 4
With your kids
1. Start a journal or research folder to record some of the things you are learning about plastics. On one page start a vocabulary list of words you are learning. (For example, the words our family has come up with so far: marine debris, nurdles, gyre, food chain)
2. Add a couple of new words to the list, look them up, and discuss:
biodegrade
outgas
leach
phalates (I suggest you visit this wikipedia link, and jump to the section called "Health Effects--Exposure")
3. Start a science experiment to observe how plastics biodegrade in comparison with organic materials:
--Make a space outside where you can set up some containers. Use whatever you have on hand--yogurt tubs, flower pots, etc. A great way to repurpose some of your unwanted plastic! ; )
--With your kids, select a variety of things natural and plastic to bury in dirt, one item in each pot. You can also bury the items directly into the ground, if you prefer, but be sure to mark what is buried where. Our family buried one plastic candy wrapper, eggshell, a pine cone, a stick, a watermelon rind, a piece of old towel, a piece of paperboard, a fresh tree leaf. (It would be ideal to include a supposedly biodegradable plastic, which I am going to add to our collection when I can.)
--Water your "garden" and then sit back and see what happens! Ideally this project you would keep going all summer--or as long as your kids are still interested. You can dig up the items whenever you and the kids think a reasonable time has passed to see what is going on. Consider with your kids how conditions like dry or wet soil, heat or cold might contribute to the biodegrading.
(If you are composting, an alternate project could be throwing one or two plastic items into the mix for easy comparison.)
For further investigation
Watch Pt. 5 of "Addicted to Plastic" on youtube--let it buffer and then jump ahead to 1:56--and Pt 6.
And then read this article, and be sure to check out the related photo gallery.

Plastic in Our World: Day 3
1. Review what you learned in Day 2 about the ocean gyres and marine debris.
2. Speculate together what all that plastic in the ocean might be doing to the different kinds of animals that live in the ocean. Then watch this solemn youtube video. It is appropriate for all ages, but I recommend you watch it with your kids, because it is sad. (Can you recognize any of the plastic bits?)
3. Look at the other images below, and talk about them.



A turtle named "Mae West" who you can see more of here.



4. Read together this article about the three (mainly plastic) bits of your trash that are most dangerous to wildlife
5. Read together this article about how one woman took what she had learned about plastic and sea life and helped her community find ways to be part of a solution.
--a great website for research into marine debris.
--more photos and information about this issue of plastics in the ocean
Website of the day: Hawaii: Message in the Waves, the website of a new BBC documentary.
Note from Lisa--Today's lesson was a downer, that's for sure. The truth is often ugly. But we can't hide from it, as we are learning! If this post was too graphic for your taste, don't worry--we are moving on to other aspects of plastics tomorrow, and in upcoming days will discuss the good things about plastic as well as the bad. : )
Plastic in Our World: Day Two
(So sorry this post is coming so late. I was planning out the lessons this morning, and then the day had its way with me! Also, I was going to post this assignment tomorrow, but found out today is World Oceans Day AND No Plastics Day, so switched things around accordingly.)
On your own
1. Visit Fake Plastic Fish, peruse today's entry, and share with your kids what you want. *The art exhibit at the San Francisco Academy of Sciences to which she refers is one of the planned field trips at the end of this plastics unit! Stay tuned for more details.
2. Read about the Ocean Garbage Patches on wikipedia, and this article.
With your kids
3. Introduce the ideas you think are important from what you read.
4. Watch this clip on youtube.
If you want to learn more
--Check out the documentary Addicted to Plastic, parts One and Two on youtube.
Website of the day: Mindfully.org
Loads of helpful and interesting articles in this section on plastics.
(Please remember, I am making these little lessons super easy and accessible so that everyone feels like they can join in and get the basics. Once you get exploring, esp. online, there are loads more things to learn. Please build the fun and educational opportunity by sharing the things you and your family find in the comments section!)

Plastic in Our World: Day One

I will be keeping each day's assignment short and sweet, and it is up to you parents to decide how much or how little you want to invest in each day's exploration--but might I encourage you to consider comitting to 15 minutes a day for the next two weeks? You can learn a LOT in 15 minutes, and some of what you learn might positively impact your family and your world forever!
For DAY ONE:
With your kids
1. Briefly explain what plastic is. Of course a quick Google search will give you lots of fodder, but those speaking in generalities, the key ideas are that:
--the term plastic means it can be molded
--all plastics are man-made (compare to natural materials)
2. Go on a plastics hunt. If you have several children, have them each pick a different room of the house to explore. They can list or just point for you out all the different objects made of plastic. Talk briefly about how/why plastic is used in some of the examples, esp. compared to natural materials. (For example, is your milk jug plastic? Why or why not? Why might plastic be serving your family well in this example? Is there anything else that could be used to hold your milk? How does it compare to the plastic jug in its service?)
3. Start saving your plastic. Dedicate a big (plastic! ; ) trash bag or box to collecting all the plastic you will throw out this week. Every time you would throw out or recycle a piece of plastic, instead add it to your collection. (I recommend rinsing out sticky food items, so your collection does not get gross!) Collect in the same bag for one week. Then start a new bag/box for week 2. Our family saved our plastic for one month, and it was really eye-opening, so consider doing that. But 2 weeks is still plenty to get you and your family aware of how you use/consume plastic.
Website of the day: Fake Plastic Fish
This is the site from which I got the inspiration and much of my information for this unit--peruse at will!
Please join us in studying Plastic in our World!

Hello moms!
Our family has been learning about plastics for over a month now, and it is truly eye-opening and fascinating. So much of what we study and learn in our homeschooling is interesting and useful--but how often does what we learn have impact on our home, our health, and our world? This unit of study has been one of the most important we have done all year.
So, I have decided to create an EASY online unit for anyone interested, to help anyone jump in on the learning! I will make it a two week course, but you can of course delve deeper, or just touch on the basic elements. Each day here on TWIOC I will post one new lesson--expect it to be easy and short and not require special materials.
Our unit will culminate in one--potentially two--field trips, and a student art show!
So please pass the word around, and share the website link with anyone who might be intersted in joining us. This is not just for homeschoolers, of course! With school out for the summer, some public-school parents might be interested in channeling their kids towards something productive for a few minutes each day. : )
Questions? Post them here in the comments.
I hope you all consider joining us!
Lisa C.
P.S. I am not by any means an expert on this subject--so informational comments, resource suggestions, etc. will be more than welcome from any participants!

Worms!

One of the blogs I read shared the other day a complete how-to on making a worm wonderland--sounds like such a fun and educational project for kids. The author said it was a good rainy day project, but I get the urge to do such things outside when the weather is as beautiful as it is this week.
I am so going to do this.

The Great Sunflower Project
Hi everybody! Just received this email from another homeschooling family and thought it may be of interest here.
Enjoy!
Sarah
Recommended Website:
The Great Sunflower Project
The Great Sunflower Project is on for 2010! Join this nationwide endeavor to help biologists reach their goal of documenting bee pollination in the US and developing strategies to protect and restore native bees where they are threatened. To participate you simply:
- Sign up at the website.
- Get and plant "Lemon Queen" sunflower seeds.
- Once your plants have flowered, count the number of flowers on your plant with pollen.
- Use the instructions and data sheets provided at the website to record the number of bees that visit your sunflower over a period of 15 minutes.
- Enter your data online at the website.
The parameters have changed slightly for 2010, and the folks at The Great Sunflower Project are in the process of modifying the data entry form on the website to reflect the changes. It isn’t quite finished, however, that shouldn't stop you from getting your seeds in preparation to plant as soon as night temperatures stay above 55 degrees in the area where you live.
Last year, The Great Sunflower Project distributed free Lemon Queen sunflower seeds. Due to increased costs, they are asking people to get their own Lemon Queen sunflower seeds at a local nursery or store, or pay $3.00 (covers padded mailers and shipping) to order them directly from The Great Sunflower project.
That said, you can still get FREE SEEDS for children in kids' programs and school groups who participate in the project. I contacted the "Queen Bee" (who goes by the name of Gretchen LeBuhn) and asked if homeschoolers qualify for free seeds. She wrote:
I love having homeschooling families participate. The real issue is the cost of mailing. So, if they can group together [i.e., request on behalf of a homeschool support group], I'd be happy to send free seeds. Individual homeschool families can also send a business sized, self-addressed, stamped envelope (with first class postage stamp on it) to:
Gretchen LeBuhn
The Great Sunflower
Department of Biology
San Francisco State University
1600 Holloway Avenue
San Francisco, CA 94132
Include a note that explains you are a homeschooler who wants to participate in The Great Sunflower Project, and Gretchen will put seeds in the envelope and mail it back to you. You STILL have to sign up to participate online at the website, where you'll also find instructions for planting the seeds and caring for your sunflowers.
You'll also receive the free eNewsletter with updates on what the researchers are learning about bees.
