Sunflower Competition

As part of our school Science Week, Primary Six have been learning about seed germination and plant growth.  Each group planted a variety of sunflower, cress and broad bean seeds. In the forthcoming weeks we shall be caring for our young seedlings and checking their progress each day.

With our sunflowers we have been set the challenge to see who can grow the tallest sunflower and the fullest bloom, to allow us to participate in this years Horticultural Society Competition. We shall keep you posted with updates.

DNA Detectives!!!!

Primary Six have really enjoyed Science Week in school with the help of our Wee Science Explorers Team. Our class DNA experiments were really successful. With the Strawberry DNA experiment, we  extracted, isolated, and observed the DNA of a strawberry in a matter of minutes. It sounds impossible, but thanks to special characteristics of strawberries, it was actually very possible… and simple!!

To extract the DNA we first had to squish some fresh strawberries. A mixture of dishwater soap and salt became our extraction liquid. After mixing the extraction liquid together with the strawberries we then sieved. Next we added a small amount of isopropyl to enable the separation process to begin. Slowly we mixed together for 30 seconds and we could clearly see the DNA strands of the strawberry  as a white layer on top of our test tube. Amazing results!!
