Can plants grow in different soils? by Daimai

I wanted to know if plants could grow in different soils. My hypothesis is that I thought that the sand plant won’t grow,and I thought the soil plant was going to grow.
How I did the experiment was I got two buckets then I got sand and soil then put  the sand in  one bucket and put the soil in the other bucket.

Later  I made two holes so both buckets have one hole. Finally I put some  bean seeds in the hole  then covered the holes with soil then we put some water  in each week. I noticed that the sand plant grew a little bit and the soil plant grew big and fast.

The  sand plant  grew slow. The colour of the sand plant was white and sort of grey and it grew facing the floor. The other plant was green and tall and the leaves were huge. 

I found out that the reason the sand plant was white and grey was because it was not facing the sun. The other plant was facing the sun. The leaves on the sand plant were small because they didn't have enough water and I gave the other plant lots of water. I found out that plants need nutrients to grow big and healthy.         

Can plants grow without oxygen? by Fa'amanu

Can plants grow without oxygen? My hypothesis is that the plant might not grow without oxygen.

I planted two bean plants, one with oxygen and one with no oxygen. I tied it up with a plastic bag.
I wanted to find out if plants can grow without oxygen.

I noticed that the plant went curly when it grew inside the plastic bag. I also noticed that the leaves of the bean plant were thin and small. When this plant grew it took so long to grow. The plant that was out the plastic bag grew very fast and well. It looked very healthy and strong. The next thing I noticed was the size of the plant. The plant that was out of the plastic bag was the size of a book. The one in the plastic bag was the size of a pencil.
I found out that the reason the bean plant inside the plastic bag grew really slow because it didn't have any oxygen in the plastic bag. The bean plant in the plastic bag did not have any space to grow that's why it grew curly. The reason the leaves were thin and small was because it was not strong and healthy. I still think that if the plant had no oxygen it would not grow, but there were holes in the plastic bag that's why it grew a little bit.
I found out the plants need oxygen, sunlight, water and nutrients to grow big and healthy.

Experimenting with Plants and Sunlight - by Kauri

I wanted to find out if plants can grow without sunlight.

My hypothesis is that I thought the plant was not going to grow.

For my experiment I got two plants and put one plant in the sunlight and the other plant under a box so it had no sunlight.

I noticed that the plant without sunlight is curved and the one with sunlight is tall and has big leaves.
I also noticed that the plant without sunlight looked very sick and the plant with sunlight does not look sick.The sick plant grew slow and the other plant grew fast.

I found out that the reason the plant that is sick grew sideways was because it got trapped in the box. The plant with sunlight grew with nice leaves because it got lots of sunlight. The sunlight gives the plant lots of chlorophyll to make the leaves green. I found out that plants need oxygen, sunlight, water and nutrients to grow big and healthy.
