So our plant experiments are a bust. There's no growing at all, and we know that plants do grow. We figured that the conditions we set up failed to make them grow. It's just too hot in our classroom and soaking the beans to give them the water they need looked like we may have drowned them.
But that's okay!
So like any good scientist does, we can depend on the work of other scientists. We watched this video in class to help us better understand where plants get their food from, and ultimately, make them grow bigger! It made us laugh knowing that other people think plants get their food from soil...but we know that's not the case at all!

Where Do Trees Get Their Mass From?
Complete unedited interviews: http://www.youtube.com/watch?v=8dcw98B2Nzg Trees can weigh hundreds or even thousands of tons, but where do they get this mass from? A few common answers are: the soil, water, and sunlight.
Mrs. Brinza also developed this model with the class to help understand how plants, along with water and air, have a relationship that helps plants grow.
It's a simplified model for a more complicated process (photosynthesis), but we're not there yet in our understanding.
That's for later in middle school!
