Our Crop Plant Study: Corn!

Our crop plant study as part of the June Newsletter suggestions focused on corn. Yes, corn. We haven't had much luck in the past growing corn but we wanted to try again this year as part of our Three Sisters Garden where we plant corn, beans, and squash as companions. (There is an official Corn Crop Plants Challenge on my sidebar. You can just observe an ear of corn and make an entry if you wish.)


We did some reading beforehand and realized that we needed to plant more corn than we usually do so it will have a better chance of pollinating. We planted the corn in mounds and have let it grow to around six inches high before planting the beans around the corn and then pumpkins in alternating mounds between the corn. You can find complete directions HERE on Renee's Garden website (love this website).


Here are our young corn plants. We have been using homemade compost to enrich our soil and every time I dig around to weed the mounds I find oodles of earthworms. I am hoping that is a good sign for our corn and its health.

We had to put tomato cages around each mound for now to keep the critters out.....human kind and canine kind as well.


I noticed that there is a potato growing in the row so we decided to leave it and see what happens with it. We have never grown potatoes but there must have been one left in the compost when it was dumped in this section of the garden.

We read in the Handbook of Nature Study that corn study can take place in the spring as soon as the leaves appear and that because the corn plant grows so fast that it is a great season long study. We will be watching anxiously as our corn grows and in Lesson 168 in the Handbook of Nature Study there are many interesting observations to make as the plant grows.



You can purchase a set of notebook pages to go along with all the Crop Plants studies in the Handbook of Nature Study HERE. There are also challenges listed on the right sidebar of my blog to go along with them.



We are also anxious for our green beans to start their vines...our poles are ready!

Don't forget to post and then share your crop plant study with the Outdoor Hour Challenge Blog Carnival. Here is the link to ENTER.

Corn Study, Fibonacci, and Our Garden: Our Family Outdoor Hour

We started off our study by reading the pages in the Handbook of Nature Study about corn. There were some great details in there about corn and how it grows and the purpose of each part of the ear of corn.


We followed the outline of the questions on page 603 to go a little more in depth with the ears of corn that we had purchased for this study. We ate the corn after our study and my son described the taste as "sweet and crunchy".


Here is a little excerpt from my son's journal page:
"The rows are more orderly near the top and become an irregular mess near the bottom. This is partly due to the lack of space but also because the slight curve of some pushes others over and they push the next and so on. The end has little definable shape but is long in some parts and stops short in other rows. "

Closely examining the ear of corn was really quite amazing, proving once again how taking a few concentrated minutes to study something commonplace produces a whole new appreciation for its beauty and design. We started wondering if corn follows the idea of a Fibonacci number or sequence and we did a little research. Here is a simple explanation about corn and the Fibonacci number (reference to evolution). Here is a video if you are interested in learning more about this fascinating topic.

We are constantly amazed at the design that our loving Creator has put before us if we only take the time to really see and appreciate.


Okay, back to our study. We germinated some corn kernels as part of our weekly nature study and we were all surprised that in a matter of days we had real corn plants growing. I unzipped the bag to allow the stems to poke out and they have continued to grow. The photo above is after five days of germination. I highly recommend this easy experiment as a way to see the process of growth. (The instructions are in the original challenge.)


We also planted some corn in our garden at the beginning of the crop plant challenges a few weeks ago. They are starting to get taller each day. I think we planted too many in our square foot...we shall see.

While we were out in the garden we noticed that our winter squash is finally forming.

We have two plants with about three squashes each so that will be a good crop for a first try.

Another new plant in our flower garden is the gladiola.

I planted shades of purple and they are gorgeous.


The glads are starting and the hydrangeas are fading. They are still very pretty even if their color is not as vivid. I am going to cut a bunch and keep them for dried flower arrangements.

Outdoor Hour Challenge: Crop Plants-Corn

This week we are going to learn about corn and hopefully you will be able to observe an ear of corn up close. In addition to learning about corn, do your best to spend some time outdoors enjoying the summer weather. If it is too hot in the afternoons, try going outside in the early morning right after breakfast or in the evening and see if that makes it more enjoyable for your family.

I found a YouTube video that I enjoyed watching that you may want to view and share with your children.



I like how it shows a lot of different aspects of corn growing that I never thought of before.

How about a video about popcorn?

I see something else we could eat this week!


Outdoor Hour Challenge
Crop Plants #3
Corn and Maize

Inside Preparation Work
1. Read in the Handbook of Nature Study pages 598-604. Highlight any facts about corn that can be shared with your children during the follow-up activity.




Suggested activity:
“Corn should be germinated between wet blotters in a seed testing experiment before observations are made on the growing corn of the fields.”
Handbook of Nature Study, page 601

Follow the same procedure that you did with the bean germination to germinate a few kernels of corn. The Germinator
http://pbskids.org/zoom/activities/sci/germinator.html
(This project was a part of Outdoor Hour Challenge #19 and the Bean Challenge.)

Outdoor Time
3. For this challenge, spend 10-15 minutes outdoors. Afterwards, you might include a trip to the grocery store to pick out some ears of corn to observe and then to eat at a meal. Check on any seeds or plants that you have in your garden for the challenges. Keep your eyes out for some clover if you have not had the chance to study some up close yet.

Follow-Up Activity
4. Allow time for discussion and a nature journal entry after your outdoor time. Follow up any interest in any subjects you observed during your outdoor time. You can use the questions in the Handbook of Nature Study on page 603 to help you observe an actual ear of corn. (If you purchased the Crop Plants notebook pages, there is a place on the corn page to record your answers.)

5. Prepare corn for eating and enjoy! You may want to pop some corn and have a popcorn feast as well. You may wish to view this YouTube video about popcorn: http://www.youtube.com/watch?v=q2lKV02JzPc

Here is a corn coloring page for you to print for younger students:

We are thinking about growing some popcorn next year. Here is a link with some information:

New for this series of challenges are custom made notebook pages for each crop plant we will study. I have designed simple to use pages that will complement each challenge and will be an easy way to start a nature journal. Each of the eight notebook pages is in full color, but they are just as great in black and white. These notebook pages can be purchased for $2.50.

SAMPLE

As usual, you can complete the challenges without the notebook pages or you can use freebies from the top tab of my blog.
