Get ready. Here they come! Is your lesson plan finished? Have you lined up the materials needed? Have you arranged the greenhouse with signs needed for student work? Let's get serious. And prepare to take those pictures so that we can post them on this blog for Mrs. Nagle's students to see. Send a comment about your progress for a grade.

For additional ideas, read about "plant parts at work". See the link to this page.
Today please prepare a detailed outline of the lesson for Mrs. Nagle's class. You may work on the computer in room 106. Your work can be converted into a Smart Board lesson after you have provided the details.
Photography
Take digital photos of the greenhouse as it appears now.
Tomorrow
There should be more seeds planted for your own discovery purposes. Most of the plants in the greenhouse have been provided. Now let's see what you can do.

Please be sure that you log in your daily accomplishments in your notebooks. Your notebook is one of the assessments that I will use for your grade at the end of the term. If you were absent on a given date, write the date, and the word ABSENT.
Today, after you have watered your plants, turn your attention to the lesson building task for November 8.
Homework: Check the blog for instructions and send a comment.

I have reviewed your comment and want to make the followng suggestions for your presentation to the students. It should be a presentation with more detail. What do you know about seeds that you will tell them? Tell me what you will tell them! You have not given me enough details.
They will bring in a seed collection. Their collection may have a mixture of monocots and dicots. They won't know which seeds belong to which category. You may want to have them make a poster collectively of all the types of seeds they brought in. Can they name the plants they came from? Could you teach them to draw a seed and label its parts?
You can prepare a presentation that tells the kids what a seed is. Explain that it has parts, and that in a dicot seed, they can easily see the parts. You might give them peanuts to look at and pull apart. You could talk about the different shapes and sizes of seeds. Have some other seeds to show them that were grown in the greenhouse. Ask them if they want to plant any of their seeds in their milk boxes. Or give them all the same kind of seed to plant in the boxes so they can compare the rates of growth. You will have to include some information about the seeds needs for germination. You might also have the children predict how seeds get dispersed from one place to another.
They should be able to return to school with a completed project that day that Mrs. Nagle can post on a bulleting board perhaps. After reading the seed collection information, do you have any other ideas for projects? We need more brainstorming so that this is an effective presentation and collaboration.

A lesson for Grade 2.
Garden Girls,
Please read about seed collections by clicking on the link under "Readings". Write for me what you know about dicot and monocot seeds. List their parts and functions. Also tell me what seeds need for germination. Consider modifying the seed collection activity for your students when they come with their seeds. If you have a question, click on comments and post your questions.

Dennis-Yarmouth Regional High School had just completed renovations which had disrupted the school for more than two years. The science labs reopened and the greenhouse that had been renovated for handicap access was once again available for use.
It was time to fill it with greenery. The revitalized greenhouse came with a new potting bench and wider access to plant tables. I had previously written and received a grant that allowed us to purchase a new garden shed that we located next to the greenhouse. This allowed us to store potting mixes, buckets, shovels, pots and boots! I knew little about running a greenhouse however.
I was teaching Ecology during semester one of the 2006-2007 academic year. I decided that one way I could get the greenhouse back up and running would be to have my Ecology students learn more about plants. We began by conducting a competition study planting bean seeds in pots, some with few and some with many.
The first day that I brought students into the greenhouse, it was a cloudy, rainy winter day. They stood in the empty greenhouse with the rain dropping noisily above their heads. Amazingly, they expressed their wonder and pleasure about just being in this big glass room. And then, getting their hands dirty at the potting bench was another joy. They asked daily to check on their plants. And their plants grew! They pressured me to allow them to plant other things. I searched my garden shed and found packets of seeds that were certainly more than two years old. We planted them. To our collective amazements, many of them grew. We had sunflowers, marigolds, coreopsis, herbs, lettuce, and radishes. The space was becoming greener and greener.
When the semester was coming to a close and final projects were submitted, I asked my students to reflect on their experience in the greenhouse. Their response was more than positive. I asked them to suggest how I might use their bean plants during the next semester’s Ecology class. They responded that no one should touch their plants! In fact, they asked if I would provide a course in horticulture semester two. I explained that it takes time to develop a curriculum and that new courses also had to be approved by the School Committee. There were only five days between semesters to accomplish this feat. I did say that I could offer an Independent Study Course for any students who could fit it into their second semester schedule. Within that day, several students appeared in the guidance office to sign up for this Independent Study. I rushed myself to the Principal to request his permission to proceed with my proposal. He was delighted to do so.
Two students were able to adjust their schedules to take an Independent Study in Horticulture. None of us knew anything about greenhouse management but all of us liked to work with plants. The School to Career Coordinator at D.Y. sent me a message that an Externship Grant was available. She wanted to know if I would be interested in applying. What timing! I immediately applied to learn about greenhouse management and the propagation of plants. I have since worked for three different nurseries, Country Garden, Hyannis, MA, Hart Farm, Dennisport, MA and Seashell Gardens, West Dennis, MA. The experience not only informative but also amazing!
