G’day, I’m David from the Questacon Science Squad, and today I’m
going to show you how to make your very own mini greenhouse.
This is what you're going to need: a couple of plastic cups,
some seeds, some cotton balls, some water and some sticky tape.
Alright, so take one of your cups and grab a few cotton balls out
of your bag here and place them in the bottom. That’s plenty.
Next off, grab a few seeds, you don’t want too many, and put
them in top of your cotton balls there. Few more. There.
And a little bit of water. Now this is difficult,
you don’t want to use too much and you don’t
want to use too little. You want the cotton balls
to just be a little bit damp. There we go.
If you see water floating around the bottom, it probably
means you’ve used too much. That looks just about right.
Ok, now, take your second cup and place it on top of your
first one, with your seeds and your cotton balls inside it.
Grab a nice big bit of sticky tape, and sticky tape it all together.
There we go. You might need a few different pieces on here.
Looks like I’ve done pretty well this time.
Alright, so you’re going to want to leave your
little greenhouse in an area that gets a little
bit of sun each day and also gets a little bit
of shade, it isn’t too hot, it isn’t too cold.
You should leave it for about two weeks, checking it daily. And when you come back
after about two weeks you might have a few little plants growing inside there.
Now if you want to find out more about greenhouses you can head on
down to the Questacon Science Squad website.
I’ll see you next time.
