How do seeds grow

Plants come from seeds. Each seed contains a tiny plant waiting for the right conditions to germinate, or start to grow.

There are three needs to be met: water, warmth, and a good location (soil) .

During the early stages of growth, the seedling relies on the food supplies stored in the seed until it is large enough for its own leaves to begin making food through photosynthesis.

The seedling's roots push down into the soil to anchor the new plant and to absorb water and minerals from the soil. The seedling's stem with new leaves pushes up toward the light.

The new plant need water, warmth, nutrients from the soil, and light to continue to grow.

Materials: Jam jar, napkins, seeds.

We used black bean, and mung bean.

First we put some napkins in the jars, then I pushed some beans down the napkin near the jar.

I left those two jars in a sunny spot.

Please remember to water everyday, keep the napkin wet.
