PLANT GROWTH

-


I believe that the science activity from the previous article needs a little more explanation. A great way of  constructing the knowledge of kids is the constructivism. What is it? The child discovers the knowledge whereas the role of the teacher (or parent) is supportive. The main goal of the following activities is to help kids develop abilities and scientific knowledge regarding the natural environment.
Phase1: Orientation and Promotion of ideas
Firstly at the observation center you may present to your kids images that plants flowers and trees are shown.




What do plants need to grow?
Which is the food of plants?
Why the leaves are green?

You let the kids think the questions individually and may give them the following worksheet. (I found the flower here to make the worksheet)


After you may gather the children's work and discuss all together the answers without telling them the right answer. You may hang the worksheets on the bulletin board (or on the wall) so as later to compare them with the new reconstructive knowledge.

Phase 2: Reconstruction of ideas
At this phase the children may plant the beans. The kids may put some beans and cotton in two utensils. The one utensil should be at the sun whereas the other should be hidden in a box or wardrobe (wherever we can keep it away from the sun). The kids need to water both utensils with the seeds. After one to two weeks the plants will grow.



What happened at the seeds which were in the sun?
What happened at the seeds which weren't in the sun? 
Why do you believe this happened?

Phase 3: Implementation of ideas

You may ask children the next question so as to see if the new knowledge which kids get can be implemented in other similar situations.


What if we cover some plant's leaves with silver foil while the whole other part of the plant is in the sun?


Phase 4:Review
At this phase the kids are asked to see and compare their first ideas about the plant's growth with the reconstructive knowledge they acquired. You may give the worksheet that kids have answered at the first phase. Then you may discuss about the answers and may make a craft which may present the plant growth.


The kids may draw with liquid glue the sun, the cloud, the rain, the seed, the plants and the roots. You should let it dry and then the children may paint the cardboard with watercolors and stick beans to the seeds.

CHRISTMAS TREE CRAFT

Christmas are coming! So I am starting preparing crafts for kids. The first Christmas craft which my children wanted to create was a Christmas tree . Firstly the kids   painted their hands with green tempera and left their handprint on the white cardboard. When the tempera dried, the kids put in the red and yellow tempera their finger so as to make the Christmas lights of the tree.   Then I joined the lights with a black marker, I draw the tree trunk with a brown marker and finally with the glitter glue I created the star !!

KIDS AND THE BEANSTALK

While I was walking yesterday, I found this huge beanstalk which touched the clouds and just below it a young man. His name was Jack and he wanted to climb on the beanstalk. He suggested me wait until he returned. So I was waiting and waiting and waiting when a letter fell on my head: Here starts the first activity. At this point you start " hiking " with your kids. You stretch your body and hands upside down while you are on your toes. You with your toddlers go from branch to branch stretching a little more your body. You may need to take great steps (like a giant) so as to pass over a branch or to jamb (like a rabbit) so as to pass over a huge bean or even to go down on the ground (like a snake) to pass over some leaves. During these exercises you may listen the song of Grieg "In the hall of the mountain king" and as the song becomes faster you may do the exercises more quickly.  Some point we arrived at a broken branch. To pass ove...

Christmas Ornament Craft

We are going to decorate our classroom’ s Christmas Tree the next week so kids decided to make their own ornaments. Their favorite handmade Christmas ornament is the following. To make this I cut bottle corks (each one in three pieces). The kids have been divided in two groups. The first group painted the corks with light green tempera whereas the other with dark green. When the last group finished I sprinkle the corks with green dust. Just the corks dried kids glue one light green cork and one dark green cork together alternate in the shape of circle. Finally I glue a red bow at the middle of the Christmas Wreath and a rope just behind the bow! We are looking forward to decorating our Christmas Tree!!!
