BIO: EYH Ecology - The Genius of Graeme Base #2 and a Refreshing Final Project

At first glance, you probably won't know how the following three items go together.






These three items did come together nicely, however, for a fun lesson. 

Odzala is a national park in the Republic of the Congo. The video we watched centered on a water hole within Odzala, which they call a bai. I had purchased Graeme Base's The Water Hole at the same time I purchased his other books and had been saving it for this unit. With the video using the word bai repeatedly, I wondered if that's where the name for the "new" Bai drinks came from. We'd never had Bai drinks before, so I purchased some to sample as a nice Eat Your Homework addition.

It turns out that bai is the Mandarin Chinese word for "pure" and it's also an acronym for botanical antioxidant infusions. That's what Bai, the company, has to say about it. The drinks are an interesting thing to learn about in and of themselves, and they fit right in with our ecology unit because a main ingredient of Bai drinks is coffeefruit--the part of the plant normally tossed as waste after coffee beans are taken out of the middle of the fruit. 

Anyway, this is how things went:  We watched the video and talked about our thoughts and reactions (because there are some unexpected things you learn relating to some animal's behavior).  A couple of days later we reviewed some things, including the word bai. The bai in Odzala is of course a very important source of nourishment for the animals there, and not just because they need water but because of what is growing in and around that water for food. I pulled out the Bai drinks I'd purchased and told them about my word association and what I'd learned about the drinks. Then, while sipping our nourishing, refreshing Bai drinks, I read aloud The Water Hole.

The Water Hole is, first and foremost, a visually delicious picture book. Base is a wonderful artist and a genius with clues, mysteries, and hidden pictures. The Water Hole is also a counting book, but we of course didn't need to use it for that. I used the book as a little test. We were nearing the end of our unit and in the background of each two-page spread is a geographical clue. My test for the kids was to see if they could name the biome and the location on the planet that each of these pictures represented. It was a fun little activity and they passed with flying colors. (They later examined the book individually, looking for the hidden animals.)

This segued into my assigning them their final project for the unit. Each was to choose a country--any country--and create a PowerPoint on that country from an ecological view. What biome(s) make up that country? What makes up the wildlife? How does it affect agriculture, industry, economy? What are people's lives like as a result? I required a minimum of 10 slides. Later, after each did the research and made their slide shows, they presented them to the family.

BIO: Ecology - Creating Mini Biomes

It would be awesome to have the budget to travel to every single biome in the world during a unit on biology/ecology. You can fake that with a trip to some top notch zoos or aquariums (14 thumbs up and a van-full-loud "Huzzah!" for Omaha's Henry Doorly Zoo & Aquarium in Nebraska in that respect--plus, it's just our favorite zoo).

You can also get up close and personal with identifying and matching plant and animal life to their proper biomes by creating miniature ones at home. 

For our unit, we created two:  a desert and a rainforest. Our local Walmart had an impressive variety of plants from all over the world, many of them identified by country. I had my kids go through all their old toys to find plastic animals and separate them into like ecosystems. (There were a few that we weren't sure exactly what they were so that made for some bonus research.) 

For the desert we used an old, large glass bowl. We put a layer of rocks on the bottom for drainage, then used some soil especially for cactus and succulents. No one wanted to chance touching the cacti, so I got to sacrifice for science. Lo and behold, some cactus plants have spines even in their roots, so this proved trickier than I thought. I did end up with bits of spine stuck in my fingers, but I lived.



The cool thing about creating a mini rainforest is that if you do it right, you get to watch the water cycle in action and you really do have a rainforest. I purchased a medium-sized, inexpensive glass aquarium to do this in but you could use anything clear that you can seal off, including a soda bottle. I just wanted it on a larger scale. Select your plants based on type, but also find varying sizes to represent the forest floor, the understory, the canopy, and an emergent tree. Again, we put a layer of rocks on the bottom for drainage, then I used just regular potting soil with fertilizer in it. We planted our flora, placed the fauna, and then thoroughly watered the soil. After that we put the cover over the aquarium. (Depending on the type or fit of your cover, you may need to use packaging tape to help seal it better.) We put it near a sunny window.





We didn't have to wait long for evaporation and transpiration to begin. That was followed by condensation... and "rain."





After a few days it's a good idea to take the top off and let some fresh air circulate. When you do this, let your kids get their faces and hands inside. It will smell and feel like being in a jungle!

Look! Raindrops on our plants!



We let ours air out for a while then we put the cover back on and watched it happen all over again.






BIO: Ecology - For Little Learners



One reason I have stuck with unit studies over the years is that it allows our family to "be on the same page," as in studying the same topic together, while adapting for different ages and stages. 

Regarding the topic of Ecology, Animal Friends is a great introduction for younger children. They will easily see how each animal has its own habitat and diet needs and it will segue beautifully into learning about habitats, ecosystems, and biomes on an elementary scale.



BIO: Ecology - Current Events



Newspapers are another great resource for unit studies.  In just the course of a couple of months there was an abundance of current events directly related to our unit and I shared them with my kids, following that up with a discussion when the topic led to one.

New Tiny Frog Species Found in India

New "Ant-Like" Bee Species Only in Western U.S.

"Feral Hog Apocalypse" in Texas

Wisconsin Hunter of Feral Cats a Target

Hundreds of North American Bees Face Extinction

Rusty Patched Bumblebee First to Be Endangered

Want Ad for Python Killers in Florida

Federal Cyanide Trap in Idaho Injures Boy, Kills Dog

Family Speaks Out After Cyanide Bomb

Cyanide Bombs Common in Utah and West

Group Asks for Idaho Ban on Cyanide Bombs

Utah Prairie Dogs Have Their Day in Court

China's Massive Pollution Problem

China Exports Pollution to Western US

(These last two aren't as current as far as publication goes. I looked them up, having remembered reading about it before.)


BIO: Ecology - Resources

I am often asked how I put my unit studies together, or what they look like. In an effort both to share that information and to keep better personal records on resources we've used, I've put together a fairly comprehensive list of the books, videos, and websites we used in our latest Ecology unit study. There is a good chance I have missed a book or site or two, but I've kept track of probably 95%.

These first three books we learned from together as I read them aloud. It's a good idea for every unit study to have at least one read aloud. The Last Egret is a true story from the journals of Charlie Pierce, written in an adventurous chapter book.







As you'll see later, chapter books/read alouds are accompanied by stacks of nonfiction. This particular unit was geared toward kids between the ages of 12 and 17. Some things were a bit over the 12-year-old and I adapted them. I did use some picture books; I value them and they work. Assignments and discussions then are tailored to ages and capabilities, obviously going deeper and expecting more from older kids.

We are so blessed in this era to have easy and free access to fabulous video content. YouTube has enhanced unit studies tenfold! Though not everything of value is there (like Planet Earth, which I highly recommend) there is a wealth of goodness to be found there, such as the video below.








Colleges and universities have put a wealth of information and educational resources on the Internet, along with high school teachers, museums, foundations, etc. They often have pages for children with games, video, worksheets, experiments, slide shows, and more. I definitely like using those. I was super excited to find ProCon.org, too, and will probably use it for critical thinking, debate and discussion on other topics. For this unit, we discussed at length the arguments ProCon had on Climate Change.

Hinckley's Be's


Gordon B. Hinckley's Way to Be! is a classic, and it fits perfectly as the next phase of morning devotionals that coordinate with our BIO year:  "9 Ways to Be Happy and Make Something of Your Life."

I decided to use Hinkley's "9 Be's" inside a mini unit on bees inside our ecology studies. I created a notebook page for each chapter or "be." Feel free to use them with your own devotionals.

Big Thumbs Up for NATURE BOOM TIME

A couple of months ago I came across a gem of a resource. Since I can't get my kids to the Everglades right now (no matter how awesome a field trip that would be and how much I would love to do it) I wanted some good video to watch while we learned about it, and I didn't want to have to pay for it. 

My YouTube search found me a fantastic miniseries that not only helped with our study of the Everglades but also with our entire Biology and Ecology units. Here is the series trailer, which is good to watch because it explains how the series came to be.


There are 14 videos in the series. Additionally, there are "Yeah Buddy, Friday" videos that have some interesting behind-the-scenes, preparation, and epic cross-country trip documentary.

What I love about this is that the Nature Boom Time videos are quality. They are interesting, informative, creative, and energetic. I am blown away (there's the boom part!) by the paper craft inserted for explanation. The time, work, and love that went into that!!! I also love that this is a brother and sister (and their best friend) taking on something huge together. 

It's no wonder Nature Boom Time won an award from and was picked up by National Geographic.

If you like Charlie and Kirby and what they do, they have also done some other DIY videos about other subjects.  Just head to World by Charlie on YouTube

Meanwhile, if someone were to ask you what the largest organism on the planet is, I betcha you'd never guess the answer.  Here it is:

Ecology - Wetlands Scavenger Hunt #2

As I mentioned in the first wetlands scavenger hunt post, I wanted to visit more than one wetland area. This is because each wetland location will have similarities and differences with the other locations. It's important to recognize things such as every time you see cattails or rushes, you know they are in water (or super soggy soil frequented by water). Children will note that wetlands are always full of birds, but the bird species will vary somewhat due to migratory patterns, food preferences and sources, and so on. For instance, you will almost always see and hear red-winged blackbirds, but pelicans will not be at every wetland location. Also, variances of visible wildlife arise due to the time of day of the visit, the size of the body of water, the current (or lack thereof), the weather, the noise of the kids, the thickness of vegetation and accessibility of habitat areas, etc.

Here are some of my favorite photos from our second wetlands scavenger hunt.

Ecology - National Endangered Species Day



May 20th (annually it's the third Friday of May) is National Endangered Species Day. Perfect timing for our Ecology unit!

Here are online resources I found handy:

*"What the Scriptures Say About: Ecology" New Era article
*"Lasting Impressions" New Era article on YW helping sea turtles
*Slide show of animals gone extinct in our lifetime
*Interactive map to learn about endangered species in your state and recovery efforts
*2016 Endangered Species Youth Art Contest finalists and winners
*Endangered Species Day Activity Book

We also used this book:


First we talked about the words extinct, endangered, and threatened, and then we shared ideas on why and how things become endangered or go extinct. Then we viewed all the slideshows together. I read the two articles aloud and we discussed them. I divvied out pages of the activity book, then independently the kids each read The Dodo is Dead book, researched and wrote a report on an endangered animal of his/her choice, and then created their own endangered species poster/piece of art.

Happy homeschooling!

Ecology - Wetlands Scavenger Hunt


As a child in later public elementary school, I hated science. All I can remember about it was textbook reading. I do recall that sometimes there were colorful, intriguing pictures in the book, and some of the things we read about sounded like they might be interesting, if only...  if only I could see and do and feel and explore instead of just read about it. Instead, we were all supposed to follow along and read a paragraph when it came to be our turn, at the end of the day, when all we really wanted was for the bell to ring so we could go home.

So, I want my kids to do more than just read about science. As we learn about biomes, ecosystems, and habitats, I want things to be as real as possible. Thus, the wetlands scavenger hunt was born. 



I created a 4-page worksheet packet for my kids to take along to help with focus and observation as we visited a wetland area. (To start, I used "The Top 75 Wetland Plants" from Among the Stately Trees as a guide, clicking on the USDA links for the map to make sure the plants I put on our list were actually found in our area, as well as the Wikipedia links for the photos.) If you'd like to use the packet I created, you can access it here:  Wetlands Scavenger Hunt Worksheets. Just remember that I created it for my state (Utah) so if you live elsewhere, some of these things will be the same and you may have other native plants and animals in your area that should be searched for. Also, my packet was by no means all inclusive, it was a starting point.  And we carried bird identification books with us. My plan is to visit several different wetland areas on different days, using a new set of these worksheets at each location.

Here are a few of my favorite photos from our first wetlands scavenger hunt.
