Have you ever grown a bean before or any type of plant? A few weeks ago Fiona(our teacher) gave us a bean, she said “You will need to set up growing conditions for it to make observations on what happens as it grows”. I was filled with excitement because I wanted to know what would happen. I started wondering
“ What type of bean is it?”. “ How much care does it need to grow?”,“How long does it take to grow?”. I also felt scared because it was a big responsibility, maybe my bean wouldn't grow.
I hypothesise that my bean seed will show its root or shoot in one week.
Fiona gave me a ziplock bag.
She gave us a tissue.
She said to wet the tissue with water.
Put the wet tissue in the bag.
She gave us a bean.
I put my bean in the bag.
I observed our bean. We have to observe our bean from time to time in our book and it take daily photos.
On the 9/8/16 I did my first observation of my bean was 1.4cm in length and 7mm in width. The colour was creamy white it was smooth to touch. The shape was like a jelly bean.
There was no leaf yet.
My inference is that it needs sunlight to grow.
On 18/8/16 I did my second observation of my bean was 1.8 cm in length and 1 cm in width. My bean has gotten longer and wider. It was still creamy white in colour and still very smooth. It was still like a jelly bean. The seed had no leaf.
My inference is that the shoot is going to come out soon.
My evidence is that there is a crack on the side of my bean.
On 29/8/16 I did my third observation of my beans length was 2.2cm and its width was 1.2cm. I noticed that my bean has gotten longer and wider. My bean is turning light green. The shape is like a purse.
It has no leaf. As the days go by I started seeing black dots on the tissue.
My inference is that the leaf is going to come out soon.
My evidence is that the root and shoot has already come out.
On 7/9/16 I did my fourth observation of my bean was 7 cm in length and 2.6cm in width. The leaves are lime green and the root was light brown. The shape from the roots to the leaves is like the letter C. My bean has 2 heart shaped leaves, stem and roots.
My inference is that the beans in the petri dish grows faster.
My evidence is there were 15 people in our class has petri dish and 12 plants grew and 24 people in our class has a bag and on 9 plants grew.
I think the petri dish gets more carbon dioxide.
On the 10/9/16 I measured the last time, my bean in length was 9cm and in width it was 3cm. The leaves are dark green and the root was light brown.
The leaves shape was like a heart shaped. It has 2 leaves, root and stem.
My inference is that it's ready to be planted.
My evidence is that it has a root, a shoot, a stem and 2 leaves. It looks like a young adult.
In conclusion, I learnt how a bean germinates and I learnt what germination mean. I also learnt that plants don't need soil to grow. The tissue just acted like soil.
