[00:03.08]Plant a Plant!My Grade One Tree My name is Anna.
[00:11.65]When I was in Grade One,I got a little tree.
[00:17.11]Everyone gets a little tree in Grade One.
[00:22.07]It's a spruce tree.See?When I brought my tree home,it was very little.
[00:30.22]It was about twenty centimetres tall--about as tall as my hand.
[00:37.49]I planted it in a pot.My mum helped me.I watered my tree a lot.
[00:45.14]In the pot,the soil got dry fast.Why did we plant my tree in a pot?
[00:54.10]Why didn't we plant it in the ground?We knew my tree was going to be big.
[01:02.56]We didn't know where we wanted a big tree.
[01:07.32]My tree slowly grew. After two years, it needed a new pot.
[01:14.45]Its roots had grown too big.So we planted it in a bigger pot.
[01:21.21]This spring,in May, we planted it in the garden.
[01:26.86]I'm in Grade Seven now and my tree is about fifty centimetres tall.
[01:34.62]It's up to my knees.Trees are good.

[01:58.15]I think that's why everyone gets a tree in Grade One.
[02:03.72]The world needs more trees!What does Anna mean by "the soil got dry fast"?
[02:12.86]This is what she means:she watered the soil,but soon it was dry again.

[03:06.93]Hi,Danny.We're doing a new project in school this week.
[03:12.89]We're learning about how plants grow. Our teacher gave each of us a pot.
[03:20.15]Then we each chose a seed.I planted a flower seed.
[03:26.32]I put it into my pot,and covered it with soil.
[03:31.77]Then I watered it.We made posters to show how our plants will grow.
[03:39.22]My seed will soon sprout.Then it will grow into a beautiful flower!
[03:46.48]This project is teaching me a lot of new English words.
[03:51.94]"Sprout":the first thing the seed does after you water it.
[03:57.58]"Stem":the long green thing that grows up.
[04:02.83]"leaves":the green things that grow on the stem.And "bud":the baby flower!
[04:11.90]Have you ever planted a seed, Danny?

[04:34.78]Date:18/03 7:02 AMDear Li Ming,Yes,I have planted a seed!
[04:48.44]We are also learning about plants in school.
[04:53.59]I told my teacher that I wanted to plant a donut.That way,
[05:01.95]I could grow lots of donuts.But the teacher laughed and said no.
[05:10.13]I asked him if I could plant an apple seed.
[05:15.59]He said that apple seeds take years to grow.That's too long!
[05:23.74]Then he said,"In Canada,we grow a lot of wheat.
[05:30.40]Maybe you should plant a wheat seed.
[05:35.15]Then you will learn how wheat grows."So I think I will plant a wheat seed.
[05:43.20]It will be fun to watch it grow!
[05:47.95]Danny How Do You Plant a Seed?What happens when you plant a seed?
[05:59.13]When a seed starts to grow,the roots sprout first.
[06:04.88]Next,the stem sprouts.As the stem grows,
[06:10.83]it pushes up through the soil.
[06:15.28]Soon you will see a little green stem above the soil.
[06:21.20]Then,the stem will grow two little leaves.
[06:26.48]Is it ok ay to plant a seed upside down?
[06:31.76]Yes!you can plant a seed upside down.
[06:37.01]It will always send its roots down and its stem up.
[06:44.66]Danny:What does "upside down" mean?I am upside down now
[06:51.61]What happens if you plant a seed too deep?
[06:56.94]Seeds need air to grow.If you plant a seed too far down in the soil,
[07:04.70]it will die.Remember not to cover your seed with too much soil.
[07:14.16]What happens after the seed has sprouted?
[07:18.83]Soon your new plant will grow more leaves.
