Science report

Do you have a garden at your house ? I don't so when kiri offered me a bean to grow I was excited because I had a responsibility to water my bean every day. I thought that would be impossible but from the first week of watering it has been easy. Kahukura has been focusing on observation so we grew beans to observe how they grow.

I hypothesise that my bean seed wouldn't grow because it wasn't in soil. 
Step 1: When I got my bean i got tissue and watered the tissue
Step 2: Then I put the bean on the tissue 
Step 3: Then put my bean on the tissue in the bag. 
Step 4: Then I watered it every day and observed it.

On my first observation on the 9th August my bean was 11mm long, pale white, smooth, shaped like a jelly bean and named Bean Jr.
My inference is that my bean will need sunlight and water.
I found evidence that confirms my inference and that was plants need sunlight so that their chlorophyll can use carbon dioxide gas from the air and water that they take in through their roots to make a kind of sugar. The sugar has energy inside and the plants use the energy to make new parts.

On my second observation the 15th August my bean has not got longer it is still 11mm, the colour has turned yellow, it is still smooth and the shape of a jelly bean. My inference is that my bean is growing because it is turning yellow. Evidence proves that my bean turned yellow in colour because the chlorophyll Is starting to develop.     

On my third observation the 18th August my bean was 17mm long, the colour was yellow, white, shrivelled and shaped like a jelly bean.
My inference is that my bean is going through stages of growing.

On my fourth observation the 4th September my bean was 17mm long,
yellow, white, smooth and shaped like a jelly bean.

On my fifth observation the 7th September my bean was 20mm long, brown, Shaped like a jelly bean and mouldy.
My inference is that my bean is dying, although that I gave the right doses of water every day and it was exposed to the sunlight I don't know why it is dying.


When I got my bean I didn't know that I was going to learn new stuff but I learnt that germination means growing and developing and I learnt that beans can grow without soil because I witnessed it geowing.
