growing radish seeds

Some students from divisions 3, 6 and 7 helped me plant some radish seeds in the library.

We created a great little growing contraption re-using 2 litre plastic bottles. I used an utility knife to create a slit halfway up the bottle and the students then used scissors to continue cutting the bottle in half. A small hole was drilled through the lid of each bottle and a piece of cotton twine was threaded through the hole and knotted so that the knot and a small length of twine was on the inside of the lid. We filled the top part of the bottle with potting soil and inverted it into the bottom half of the bottle and watered it well. We planted the seeds and added a little extra water to the bottom of the bottle, making sure the twine coming out of the lid was in the water. This allows for the water to "wick" and keep the soil in the upper layer moist which is really important for seed germination.
Hopefully we'll be eating some radishes before the end of June, and if not, we'll enjoy a radish sprout snack!
