In class, we planted some green peas and kidney beans in a plastic cup. We predict that we think the beans in the cupboard will not grow. And the beans we left outside will grow strong and healthy. We left it for a few weeks. After, we took them out and see, the ones in the cupboard did grow, but they aren't as healthy as the ones outside sitting in the sun. The cup board beans were growing in any directions and some of the stems are starting to turn brown as in "rotting", the stems are also in pail white colored.our prediction:
1. It won't really grow in the dark.
2. The stems aren't as strong as the ones under the sunlight.
3. They won't be looking as healthy as the ones outside.
The other group which had the seeds growing outside, there is a BIG difference between 2 seeding groups results. The outside one has bigger leaves, thicker stems and looking healthier. The seeds got their energy from 2 different places, 1: water 2: sunlight. The stems are in bright green colored, and the leaves are also in bright green colored.Conclusion: The differences between both plants are:
1. different sources of energy.
2. different places been set.
And the result of course is different. But our prediction about the cup board seeds won't grow is wrong, they do grow!

Dear Anzz,
I enjoyed reading what you put on your blog. I have some more questions for you about your Tuesday, March 25, 2008, entry about the plants. Please answer my questions and then you can embed Task A and Task B onto your site to answer those questions.
1. Why did the seeds in the cupboard grow? Explain why by commenting on each of the folowing:
a. Where did the germinating seeds kept in the dark get their energy?
b. Where did the germinating seeds kept in the light get their energy? (Be careful...your answer should be the same as in # a above!)
Ok, you can move on and have fun completing the other activities.

Question 1.
a. The germinating seeds kept in the dark get there energy from the water, we watered.
b. The germinating seeds kept in the light get there energy from the sun light and the water, we watered.

Dear Anzz,
Thanks for answering my questions. I have cut and pasted your comments below and respond to them in CAPS. After you read them, then please read my comments on your blog entry from last week.
Question 1.
a. The germinating seeds kept in the dark get there energy from the water, we watered.
NOT QUITE. DO YOU REMEMBER THAT THE GERMINATING SEEDS GET THEIR ENERGY FROM THEMSELVES? THERE IS ENERGY STORED IN THE SEED!
b. The germinating seeds kept in the light get there energy from the sun light and the water, we watered.
NOT QUITE. REMEMBER THAT IN NORMAL CONDITIONS GERMINATING SEEDS ARE BURIED IN THE GROUND. THERE IS NO SUNLIGHT THERE. THE SEEDS GET THE ENERGY FROM THE STORED STARCH (GLUCOSE) WITHIN THE SEED. AFTER THE PLANT GERMINATES AND THE FIRST LEAVES GROW, THEN THE PLANT CAN MAKE ITS OWN ENERGY THROUGH PHOTOSYNTHESIS. IT IS IMPORTANT THAT YOU KNOW THIS ANSWER FOR THE TEST YOU'LL HAVE AT THE END OF THE UNIT.
GOOD LUCK TODAY!
