SGS growers (Bridget, Owen, Mila, Liam)
Transcript of SGS growers (Bridget, Owen, Mila, Liam)
We could use rain water to water the plants.
The placement of the seeds in the ground and
how far down you place
them has a BIG impact on their Development .
My claim is that compost water/soil helped the lettuce to grow.
Worms can consume dry soil and release nitrogen with moist compost
It took more time for things to decompose than it did for
things to start growing!
Nom nom nom
Earthworms release slime, which contains nitrogen
days to start decomposing.
Worms ingest dry soil partially, and release it into the dirt, creating healthy, moist soil, ready for use as compost
days to start growing.
Worms help Decomposters but they
are small and there are not a lot of them:
As long as the seeds get everything
they need, they can grow quickly:
Bacteria fix nitrogen in the soil, the earthworms consuming soil may or may not interrupt the fixation process

Bacteria in the soil fixes nitrogen so it may be used by plants to continue the process of photosynthesis
Bacteria fits here
Nitrogen fits here
My claim is that plants grow better when they have compost water/soil.
When we first started out with a few handfuls of soil and some fruit scraps, there weren't any animals in the soil to process it so it would create liquid compost at a faster rate, but when earthworms appeared in the soil, there was a dramatic climb in compost water produced on that day.
Covering the seeds in a little soil
= GOOD GROWING
My evidence is that Brigdet got compost water and soil, and her plants grew a lot better than mine
my explanation is that the compost has nitrogen that the plants need to survive, and grow healthy
put seeds too far down
= Bad Growing
During the first round we placed our seeds too far down and we grew 3-4 small sprots that died soon after.
During the second round, we covered the seeds with a little soil and they were growing great.
energy in order to photosythesis/ produce food.
If the seed is buried DEEP under soil, the
light energy will never be able to reach the plant
Tap Water is unsustainable
How We Get Our Water
1. It rains into a river/lake/pond.
2. The water is flitered and cleaned
3. The water is sent to us through the sink
= Little progress
= Decent progress
Water is cleaned/filtered
The water is sent out to the sink
Nom nom nom nom
The seed is covered with a little dirt so the light is able to reach it.
The seed is placed too far under the soil, therefor it is unable to get light energy.
