We have had a very busy two weeks in Atmospheric Science. On April 6th, we went to Gateway Elementary to visit one of the greenhouses where Gibran (of HOSCO) works. He showed the teens how to plant seeds, and each teen got to bring back a tray of seeds they had planted.
On April 13th, some of the teens worked extra hours in the Planetarium for its 50th anniversary. All the teens also started work on Science Corner, did self-evaluations of their work, and checked on their tiny seedlings. Gibran also showed the teens the new aquaponics system. Everyone in YES also had a speaker who came to talk to them about teen dating violence. We've been busy!
Last Saturday, the Atmospheric Science teens went out to Science Corner and gathered some soil samples. We then brought the samples back to our room and tested them. We tested for plant nutrients as well as lead contamination. Once all the chemical testing was done, we created a chart on the board to compare our results. We found that the soil is deficient in nitrogen and phosphorus, but the potassium and pH levels are fine. So we decided we need to add nitrogen and phosphorus to the soil on Science Corner to help our plants grow. And the lead test came back with safe levels. Here's pics:
